-------------------------------------------------------------------------------- /springboot(三)/SpringBoot(三)_controller的使用.md: -------------------------------------------------------------------------------- 1 | 2 | 3 | > 针对controller 中 如何使用注解进行解析 4 | 5 | #### @RestController 6 | 7 | - 返回数据类型为 Json 字符串，特别适合我们给其他系统提供接口时使用。 8 | 9 | #### @RequestMapping 10 | 11 | (1) 不同前缀访问同一个方法,此时访问hello和hi 都可以访问到say（）这个方法 12 | 13 | ``` 14 | @RequestMapping(value = {"/hello","/hi"},method = RequestMethod.GET) 15 | public String say(){ 16 | return girlProperties.getName(); 17 | } 18 | ``` 19 | （2）给类一个RequestMapping, 访问时就是：http://localhost:8099/hello/say 20 | 21 | ``` 22 | @RestController 23 | @RequestMapping("/hello") 24 | public class HelloController { 25 | 26 | @Resource 27 | private GirlProperties girlProperties; 28 | @RequestMapping(value = "/say",method = RequestMethod.GET) 29 | public String say(){ 30 | return girlProperties.getName(); 31 | } 32 | } 33 | ``` 34 | 35 | #### @PathVariable：获取url中的数据 36 | 37 | ``` 38 | @RestController 39 | @RequestMapping("/hello") 40 | public class HelloController { 41 | 42 | @Resource 43 | private GirlProperties girlProperties; 44 | @RequestMapping(value = "/say/{id}",method = RequestMethod.GET) 45 | public String say(@PathVariable("id") Integer id){ 46 | return "id :"+id; 47 | } 48 | } 49 | ``` 50 | 访问http://localhost:8099/hello/say/100, 结果如下 51 | 52 | ``` 53 | id :100 54 | ``` 55 | 56 | #### @RequestParam :获取请求参数的值 57 | (1) 正常请求 58 | ``` 59 | @RestController 60 | @RequestMapping("/hello") 61 | public class HelloController { 62 | 63 | @Resource 64 | private GirlProperties girlProperties; 65 | @RequestMapping(value = "/say",method = RequestMethod.GET) 66 | public String say(@RequestParam("id") Integer id){ 67 | return "id :"+id; 68 | } 69 | } 70 | ``` 71 | 访问 http://localhost:8099/hello/say?id=111 结果如下 72 | ``` 73 | id :111 74 | ``` 75 | （2）设置参数非必须的，并且设置上默认值 76 | ``` 77 | @RestController 78 | @RequestMapping("/hello") 79 | public class HelloController { 80 | 81 | @Resource 82 | private GirlProperties girlProperties; 83 | @RequestMapping(value = "/say",method = RequestMethod.GET) 84 | public String say(@RequestParam(value = "id",required = false,defaultValue = "0") Integer id){ 85 | return "id :"+id; 86 | } 87 | } 88 | 89 | ``` 90 | 访问http://localhost:8099/hello/say 结果如下 91 | ``` 92 | id :0 93 | ``` 94 | #### @GetMapping ，当然也有对应的Post等请求的简化写法 95 | 96 | - 这里对应的就是下面这句代码 97 | ``` 98 | @GetMapping("/say") 99 | //等同于下面代码 100 | @RequestMapping(value = "/say",method = RequestMethod.GET) 101 | ``` -------------------------------------------------------------------------------- /springboot(七)/girl/pom.xml:

##### 简单web实战 27 | 28 | （1） 创建controller 类 29 | 30 | ``` 31 | @RestController 32 | public class HelloController { 33 | @RequestMapping(value = {"/hello"},method = RequestMethod.GET) 34 | public String say(){ 35 | return "Hello Spring Boot!"; 36 | } 37 | } 38 | ``` 39 | （2）启动主程序，打开浏览器访问 http://localhost:8080/hello，就可以看到以下内容 40 | ``` 41 | Hello Spring Boot! 42 | ``` 43 | ##### 三种启动方式 44 | 45 | （1）启动主程序进行启动 46 | 47 | （2）进入工程目录, mvn spring-boot:run 48 | 49 | ![enter image description here](http://p9d3cdwaf.bkt.clouddn.com/TIM%E6%88%AA%E5%9B%BE20180524064821.png) 50 | 51 | (3) jar包启动 52 | 53 | - 执行mvn install 54 | ![enter image description here](http://p9d3cdwaf.bkt.clouddn.com/TIM%E6%88%AA%E5%9B%BE20180524064906.png) 55 | - 执行 java -jar 56 | ![enter image description here](http://p9d3cdwaf.bkt.clouddn.com/TIM%E6%88%AA%E5%9B%BE20180524065026.png) 57 | 58 | ##### 单元测试 59 | 在 Spring Boot 中，Spring 给出了一个简单的解决方案；使用 mockmvc 进行 web 测试，mockmvc 内置了很多工具类和方法，可以模拟 post、get 请求，并且判断返回的结果是否正确等，也可以利用print()打印执行结果。 60 | 61 | ``` 62 | @SpringBootTest 63 | public class GirlApplicationTests { 64 | 65 | private MockMvc mockMvc; 66 | 67 | @Before 68 | public void setup(){ 69 | mockMvc = MockMvcBuilders.standaloneSetup( new HelloController()).build(); 70 | } 71 | @Test 72 | public void contextLoads() throws Exception { 73 | mockMvc.perform(MockMvcRequestBuilders.get("/hello").accept(MediaType.APPLICATION_JSON_UTF8)).andDo(print()); 74 | } 75 | 76 | } 77 | ``` 78 | 运行结果 79 | 80 | ``` 81 | MockHttpServletRequest: 82 | HTTP Method = GET 83 | Request URI = /hello 84 | Parameters = {} 85 | Headers = {Accept=[application/json;charset=UTF-8]} 86 | Body = 87 | Session Attrs = {} 88 | 89 | Handler: 90 | Type = com.imooc.controller.HelloController 91 | Method = public java.lang.String com.imooc.controller.HelloController.say() 92 | 93 | ... 94 | MockHttpServletResponse: 95 | Status = 200 96 | Error message = null 97 | Headers = {Content-Type=[application/json;charset=UTF-8], Content-Length=[18]} 98 | Content type = application/json;charset=UTF-8 99 | Body = Hello Spring Boot! 100 | Forwarded URL = null 101 | Redirected URL = null 102 | Cookies = [] 103 | ``` 104 | 105 | ##### 总结 106 | 使用 Spring Boot 可以非常方便、快速搭建项目，而不用关心框架之间的兼容性、适用版本等各种问题，我们想使用任何东西，仅仅添加一个配置就可以，所以使用 Sping Boot 非常适合构建微服务。

211 | userEntity.setAddress("山东济南"); 212 | amqpTemplate.convertAndSend("hello", userEntity); 213 | return "消息已发送"; 214 | } 215 | ``` 216 | 217 | （5）接收者 218 | 219 | 注意使用注解`@RabbitListener`，使用 queues 指明队列名称，`@RabbitHandler`为具体接收的方法。 220 | 221 | ``` 222 | @Component 223 | @RabbitListener(queues = "hello") 224 | @Slf4j 225 | public class HelloReceiver { 226 | 227 | @RabbitHandler 228 | public void process(String hello) { 229 | log.info("消息接受为：{}",hello);
