The default CachingProvider can be accessed via +Caching.getCachingProvider()+. This interface provides access to a number of +CacheManager+s. 12 | 13 | * +CacheManager+ 14 | 15 | A +CacheManager+ provides access to a number of named +Cache+s. 16 | 17 | * +Cache+ 18 | 19 | A temporary key-based store, similar to a +Map+. A cache can store a number of entries for fast lookup for a period of time until the entry expires. 20 | 21 | Using JCache in a Java SE way is shown in the "Hello world" example below. 22 | 23 | [source,java,numbered] 24 | ---- 25 | CachingProvider provider = Caching.getCachingProvider(); 26 | CacheManager manager = provider.getCacheManager(); 27 | 28 | Configuration configuration = new MutableConfiguration().setTypes(String.class, String.class); 29 | Cache cache = manager.createCache("simpleCache", configuration); 30 | 31 | cache.put("phrase", "Hello, world!"); 32 | 33 | String value = cache.get("phrase"); 34 | System.out.println("Value: " + value); 35 | ---- 36 | 37 | There's nothing wrong with taking this approach within a Java EE application, but notice that this example has a reasonable amount of 38 | boilerplate code, and the JCache objects created aren't managed by the Java EE container - we cannot inject them into EJB or CDI beans 39 | for example. 40 | 41 | Java EE doesn't include JCache as yet, although hopefully that will change in future Java EE specifications. In the meantime though, we 42 | can use a little of CDI fairy dust to start using JCache in a Java EE application with minimal fuss. 43 | 44 | == CDI 45 | 46 | Contexts and Dependency Injection (https://jcp.org/en/jsr/detail?id=346[JSR-346]) first arrived in Java EE in version 6, and is a 47 | required part of the Web Profile as well as the Full Profile. CDI provides the container with the capability to manage the lifecycle of a 48 | bean and the ability to inject beans into other managed components. 49 | 50 | CDI includes support for: 51 | 52 | * Injection (with scoping, names, qualifiers, stereotypes and alternatives) 53 | 54 | * Producers (factory methods) 55 | 56 | * Interceptors 57 | 58 | * Observers 59 | 60 | In addition, you can define your own CDI extensions which allow a great deal of flexibility within the CDI container. We'll specifically 61 | focus on Producers and Interceptors here. There are some easy to follow CDI examples on the TomEE website (http://tomee.apache.org/examples-trunk/index.html) 62 | and some great YouTube videos on CDI presented by Alex Soto (https://www.youtube.com/user/lordofthejars/videos). 63 | 64 | == About this library 65 | 66 | This library is made up from the interceptors and annotations from the JCache reference implementation (https://github.com/jsr107/RI/tree/master/cache-annotations-ri/cache-annotations-ri-cdi) 67 | and an additional extension that will load the JCache provider at deployment time and create CachingProvider and CacheManager CDI beans that 68 | can be directly injected into managed beans. 69 | 70 | In effect that means the code above, can now become: 71 | 72 | [source,java,numbered] 73 | ---- 74 | public class MyBean { 75 | 76 | @Inject 77 | private CacheManager mgr; 78 | 79 | public void doSomething() { 80 | 81 | final Configuration configuration = new MutableConfiguration().setTypes(String.class, String.class); 82 | final Cache cache = mgr.createCache("simpleCache", configuration); 83 | 84 | cache.put("phrase", "Hello, world!"); 85 | 86 | final String value = cache.get("phrase"); 87 | System.out.println("Value: " + value); 88 | } 89 | } 90 | ---- 91 | 92 | Note that +CacheManager+ does not need to be created any more, it is injected straight in. 93 | 94 | == Using JCache with CDI in your Java EE application 95 | 96 | To use this library in your Java EE application, include the following dependencies in your pom.xml (I'm using Hazelcast 97 | as the JCache implementation here): 98 | 99 | [source,xml,numbered] 100 | ---- 101 | 102 | javax.cache 103 | cache-api 104 | 1.0.0 105 | 106 | 107 | com.hazelcast 108 | hazelcast 109 | 3.4.1 110 | 111 | 112 | org.tomitribe 113 | jcache-cdi 114 | 0.1-SNAPSHOT 115 | 116 | ---- 117 | 118 | and you will need to add an empty +beans.xml+ file. 119 | 120 | [source,xml,numbered] 121 | ---- 122 | 126 | ---- 127 | 128 | This is everything you need to add JCache to your existing project. This library has been tested with Hazelcast on TomEE, but 129 | should be portable in work in different application servers and with different JCache implementations. 130 | 131 | === Producer 132 | 133 | You've already seen the example above, where +CachingProvider+ and +CacheManager+ can be directly injected into beans 134 | managed by the container. But, wouldn't it be nice if we could eliminate the configuration and +CacheManager.createCache()+ call, and just 135 | inject +Cache+ straight into our beans? Well, with a little work with CDI, we can. The solution here is to use a producer. 136 | 137 | At a very simple producer would look like this: 138 | 139 | [source,java,numbered] 140 | ---- 141 | public class CacheProducer { 142 | 143 | @Inject 144 | private CacheManager mgr; 145 | 146 | @Produces 147 | @Singleton 148 | public Cache createCache() { 149 | final Configuration configuration = new MutableConfiguration().setTypes(String.class, String.class); 150 | final Cache cache = mgr.createCache("simpleCache", configuration); 151 | 152 | return cache; 153 | } 154 | } 155 | ---- 156 | 157 | Notice that we simply moved the configuration and +createCache+ call into a factory method. Now we can use +@Inject Cache+ in 158 | our application code. This has some limitations though - for example we cannot use this to create different caches with different names. 159 | 160 | We could take this one step further, and use a qualifier to define different caches. To use a qualifier, you need to define an annotation. 161 | For example: 162 | 163 | [source,java,numbered] 164 | ---- 165 | @Retention(RetentionPolicy.RUNTIME) 166 | @Inherited 167 | @Target({ElementType.METHOD, ElementType.FIELD}) 168 | public @interface DefaultCache { 169 | } 170 | 171 | @Retention(RetentionPolicy.RUNTIME) 172 | @Inherited 173 | @Target({ElementType.METHOD, ElementType.FIELD}) 174 | public @interface AnotherCache { 175 | } 176 | ---- 177 | 178 | and then define different producers: 179 | 180 | [source,java,numbered] 181 | ---- 182 | @Produces 183 | @Singleton 184 | @DefaultCache 185 | public Cache createCache() { 186 | // create the cache 187 | } 188 | 189 | @Produces 190 | @Singleton 191 | @AnotherCache 192 | public Cache createCache() { 193 | // create the cache 194 | } 195 | ---- 196 | 197 | This provides us with a little more flexibility, but could become unwieldy down the line. Another approach is to define some options 198 | on the annotation that we create, and then use these within our Producer method to control the configuration and creation of the cache. 199 | 200 | For example - add a name option to the annotation 201 | 202 | [source,java,numbered] 203 | ---- 204 | @Retention(RetentionPolicy.RUNTIME) 205 | @Inherited 206 | @Target({ElementType.METHOD, ElementType.FIELD}) 207 | public @interface MyCache { 208 | String name() default "default"; 209 | } 210 | ---- 211 | 212 | and access the annotation added to the field using an InjectionPoint parameter on the Producer. Note that this does not 213 | include the +@Singleton+ annotation. 214 | 215 | [source,java,numbered] 216 | ---- 217 | @Produces 218 | @MyCache 219 | public Cache createCache(final InjectionPoint injectionPoint) { 220 | 221 | final MyCache cache = injectionPoint.getAnnotated().getAnnotation(MyCache.class); 222 | 223 | Cache cache = mgr.getCache(cache.name()); 224 | if (cache == null) { 225 | final MutableConfiguration config = new MutableConfiguration() 226 | .setTypes(Object.class, Object.class); 227 | 228 | cache = mgr.createCache(cache.name(), config); 229 | } 230 | 231 | return cache; 232 | } 233 | ---- 234 | 235 | === Built-in Interceptors 236 | 237 | Being able to create your own producer is great, but you still need to do all the work of figuring out when to add objects to the cache, 238 | when to remove invalid objects and when to fetch objects from the cache. 239 | 240 | Fortunately the JCache specification defines a set of annotations specifically for implementations to provide interceptors to do the heavy 241 | lifting for you. The JCache reference implementation provides a default implementation of these interceptors and these have been 242 | shaded into this library. 243 | 244 | These built in interceptors can be used by annotating the methods to you want to be intercepted with the appropriate annotation. 245 | 246 | The interceptors are outlined briefly below, and full Javadoc can be found here: https://github.com/jsr107/jsr107spec/tree/master/src/main/java/javax/cache/annotation 247 | 248 | ==== +@CacheResult+ 249 | 250 | +CacheResult+ will cache the result of a method call, using specified parameters as the key, using the +@CacheKey+ annotation below. 251 | Subsequent calls to the method will be checked against the cache, and the result returned from cache if available. +CacheResult+ provides 252 | some simple options, including: 253 | 254 | +cacheName+: The name of the cache to use for the result 255 | +skipGet+: Always caches the result, but does not use the value in the cache to return from the method. 256 | 257 | In a very simple case, the result of method could be cached simply by adding +@CacheResult(cacheName="myCache")+: 258 | 259 | [source,java,numbered] 260 | ---- 261 | @CacheResult(cacheName = "results") 262 | public List getResults(final Integer firstResult, final Integer maxResults, final String field, final String searchTerm) { 263 | // TODO: search code here... 264 | } 265 | ---- 266 | 267 | ==== +@CacheKey / @CacheValue+ 268 | 269 | +@CacheKey+ and +@CacheValue+ should be specified on method parameters when using any of these interceptors. +@CacheValue+ identifies the object that should 270 | be cached, and +@CacheKey+ identifies the objects that should make up the key for the for cache entry. 271 | 272 | +@CacheKey+ can be used in conjunction with +CacheKeyGenerator+ (below) to apply some logic to generate the actual key to use for the cache from the parameters 273 | annotated with +@CacheKey+. 274 | 275 | ==== +CacheKeyGenerator+ 276 | 277 | Your method may accept a domain object as a parameter, but you may not wish to use the domain object itself as the key for the cache, instead you may just wish 278 | to use an id field, for example. The +CacheKeyGenerator+ allows you to provide a class that can apply this logic. 279 | 280 | For example, a +@CachePut+ method such as 281 | 282 | [source,java,numbered] 283 | ---- 284 | @CachePut(cacheName = "domainCache", cacheKeyGenerator = DomainObjectCacheKeyGenerator.class) 285 | public void addObject(@CacheKey @CacheValue final DomainObject domObj) { 286 | entityManager.persist(domObj); 287 | } 288 | ---- 289 | 290 | could use a +CacheKeyGenerator+ like this: 291 | 292 | [source,java,numbered] 293 | ---- 294 | public class DomainObjectCacheKeyGenerator implements CacheKeyGenerator { 295 | @Override 296 | public GeneratedCacheKey generateCacheKey(final CacheKeyInvocationContext cacheKeyInvocationContext) { 297 | 298 | final CacheInvocationParameter[] allParameters = cacheKeyInvocationContext.getAllParameters(); 299 | for (final CacheInvocationParameter parameter : allParameters) { 300 | if (DomainObject.class.equals(parameter.getRawType())) { 301 | final DomainObject domObj = DomainObject.class.cast(parameter.getValue()); 302 | return new DefaultGeneratedCacheKey(new Object[] { domObj.getId() }); 303 | } 304 | } 305 | 306 | throw new IllegalArgumentException("No domain object argument found in method signature"); 307 | } 308 | } 309 | ---- 310 | 311 | ==== +@CachePut+ 312 | 313 | +@CachePut+ allows you to add or update a value in the cache with a value passed into the method as a parameter. The parameter to cache 314 | should be annotated with +@CacheValue+ and the parameters that make up the key, should be annotated with +@CacheKey+. +@CacheKey+ can be used in conjunction with 315 | a +CacheKeyGenerator+ and +@CacheKey+ and +@CacheValue+ can be applied to the same parameter if appropriate. For example, to cache an entity that is being added 316 | to the database, the following code could be used: 317 | 318 | [source,java,numbered] 319 | ---- 320 | @CachePut(cacheName = "domainById", cacheKeyGenerator = DomainObjectCacheKeyGenerator.class) 321 | public void addObject(@CacheKey @CacheValue final DomainObject domObj) { 322 | entityManager.persist(domObj); 323 | } 324 | ---- 325 | 326 | ==== +@CacheRemove+ 327 | 328 | +@CacheRemove+ can be used to remove a specific +@CacheKey+ from the cache. This might be particularly useful when the method called removes an entity from the system. 329 | For example: 330 | 331 | [source,java,numbered] 332 | ---- 333 | @CacheRemove(cacheName = "domainCache") 334 | public void deleteById(final long id) { 335 | final DomainObject domObj = entityManager.find(DomainObject.class, id); 336 | entityManager.remove(movie); 337 | } 338 | ---- 339 | 340 | ==== +@CacheRemoveAll+ 341 | 342 | +@CacheRemoveAll+ is similar to +@CacheRemove+ but will remove *all entries* from the specified cache. 343 | 344 | ==== +@CacheDefaults+ 345 | 346 | The +@CacheDefaults+ annotation can be applied at class level to provide a set of defaults for the method-level annotations. For example, you can save yourself 347 | specifying +cacheName+ and +cacheKeyGenerator+ on each method annotation by providing a +@CacheDefaults(cacheName = "domainCache", cacheKeyGenerator = DomainObjectCacheKeyGenerator.class)+ 348 | on the class itself. 349 | 350 | ==== Some limitations 351 | 352 | These annotations and interceptors can provide a really simple way to introduce JCache into your application. One specific limitation to be aware of though, is that 353 | only one +Cache+ annotation can be used on a method. So you can't for example, do this: 354 | 355 | [source,java,numbered] 356 | ---- 357 | @CachePut(cacheName = "domainById", cacheKeyGenerator = DomainObjectCacheKeyGenerator.class) 358 | @CacheRemoveAll(cacheName = "searchResults") // this is now invalid because we added an new object 359 | public void addDomainObject(@CacheKey @CacheValue final DomainObject movie) { 360 | entityManager.persist(movie); 361 | } 362 | ---- 363 | 364 | You'd need to either work with the caches manually, or define your own interceptor. 365 | 366 | === Creating your own 367 | 368 | Creating your own interceptor with CDI is really easy. Firstly, define a "marker" annotation: 369 | 370 | [source,java,numbered] 371 | ---- 372 | @InterceptorBinding 373 | @Target({ TYPE, METHOD }) 374 | @Retention(RUNTIME) 375 | public @interface MyCacheAnnotation { 376 | } 377 | ---- 378 | 379 | Next, create the interceptor. The key here is the +@AroundInvoke+ annotation and the +InvocationContext+ parameter. 380 | 381 | [source,java,numbered] 382 | ---- 383 | @Interceptor 384 | @MyCacheAnnotation 385 | public class CacheInterceptor { 386 | 387 | @Inject // use your Producer to create this 388 | private Cache cache; 389 | 390 | @AroundInvoke 391 | public Object cache(final InvocationContext ctx) throws Exception { 392 | 393 | final Object[] parameters = ctx.getParameters(); 394 | final Object result = ctx.proceed(); 395 | 396 | // TODO: your code here to work with the cache 397 | 398 | return result; 399 | } 400 | } 401 | ---- 402 | 403 | Now, you can use your interceptor in your code: 404 | 405 | [source,java,numbered] 406 | ---- 407 | @MyCacheAnnotation 408 | public void addDomainObject(@CacheKey @CacheValue final DomainObject movie) { 409 | entityManager.persist(movie); 410 | } 411 | ---- 412 | 413 | Finally, you need to enable interceptors in your +beans.xml+ file: 414 | 415 | [source,xml,numbered] 416 | ---- 417 | 421 | 422 | 423 | org.superbiz.jcache.interceptors.CacheInterceptor 424 | 425 | 426 | ---- 427 | 428 | NOTE: As well as enabling interceptors, +beans.xml+ also defines the order the interceptors run in. -------------------------------------------------------------------------------- /pom.xml: -------------------------------------------------------------------------------- 1 | 2 | 18 | 20 | 21 | 4.0.0 22 | 23 | 24 | org.tomitribe 25 | oss-parent 26 | 2 27 | 28 | 29 | jcache-cdi 30 | 0.1-SNAPSHOT 31 | jar 32 | 33 | Tomitribe :: JCache CDI 34 | 35 | 36 | UTF-8 37 | 38 | 39 | 40 | scm:git:git@github.com:tomitribe/jcache-cdi.git 41 | scm:git:git@github.com:tomitribe/jcache-cdi.git 42 | scm:git:git@github.com:tomitribe/jcache-cdi.git 43 | HEAD 44 | 45 | 46 | 47 | 48 | snapshots 49 | http://repository.tomitribe.com/content/repositories/snapshots 50 | 51 | true 52 | 53 | 54 | 55 | Sonatype-public 56 | Sonatype snapshot and release 57 | https://oss.sonatype.org/content/groups/public/ 58 | 59 | true 60 | 61 | 62 | true 63 | 64 | 65 | 66 | 67 | 68 | 69 | org.jsr107.ri 70 | cache-annotations-ri-cdi 71 | 1.0.0 72 | 73 | 74 | junit 75 | junit 76 | 4.11 77 | test 78 | 79 | 80 | org.apache.openejb 81 | javaee-api 82 | 6.0-6 83 | provided 84 | 85 | 86 | javax.cache 87 | cache-api 88 | 1.0.0 89 | provided 90 | 91 | 92 | org.apache.openejb 93 | openejb-core 94 | 4.7.1 95 | test 96 | 97 | 98 | 99 | 100 | com.hazelcast 101 | hazelcast 102 | 3.4.1 103 | test 104 | 105 | 106 | 107 | 108 | 109 | 110 | org.apache.rat 111 | apache-rat-plugin 112 | 0.10 113 | 114 | 115 | src/**/* 116 | pom.xml 117 | 118 | 119 | **/*/MANIFEST.MF 120 | .git 121 | .gitignore 122 | derby.log 123 | **/META-INF/services/* 124 | **/bootstrap-* 125 | **/js/jquery-* 126 | **/*.json 127 | src/test/resources/**/*.txt 128 | **/src/main/resources/archetype-resources/**/* 129 | **/javax.enterprise.inject.spi.Extension 130 | 131 | 132 | 133 | 134 | validate 135 | 136 | check 137 | 138 | 139 | 140 | 141 | 142 | org.apache.maven.plugins 143 | maven-compiler-plugin 144 | 3.1 145 | 146 | 1.6 147 | 1.6 148 | 149 | 150 | 151 | org.apache.maven.plugins 152 | maven-shade-plugin 153 | 2.3 154 | 155 | 156 | package 157 | 158 | shade 159 | 160 | 161 | true 162 | true 163 | false 164 | 165 | 166 | javax.enterprise:cdi-api 167 | org.jboss.spec.javax.interceptor:jboss-interceptors-api_1.1_spec 168 | javax.annotation:jsr250-api 169 | javax.inject:javax.inject 170 | 171 | 172 | 173 | 174 | org.jsr107.ri:cache-annotations-ri-cdi 175 | 176 | META-INF/services/javax.enterprise.inject.spi.Extension 177 | 178 | 179 | 180 | 181 | 182 | 183 | 184 | 185 | 186 | 187 | 188 | -------------------------------------------------------------------------------- /src/main/java/org/tomitribe/jcache/cdi/AnyLiteral.java: -------------------------------------------------------------------------------- 1 | /* 2 | * Licensed to the Apache Software Foundation (ASF) under one 3 | * or more contributor license agreements.
