8 | 9 | SpringBoot默认采用slf4j+logBack 10 | 11 | * 在SpringBoot中，只需要使用Logger logger = LoggerFactory.getLogger(Xxx.class)(sif4j包)即可获得日志对象; 12 | * yml文件中可以实现日志文件简单的配置： 13 | ~~~ 14 | logging: 15 | pattern: 16 | #控制台日志输出格式 17 | # console: "%d - %msg%n" 18 | #日志配置文件的路径 19 | # config: 20 | #日志文件输出路径，只是路径名 21 | # path: D://log 22 | #日志文件输出路径，包含文件名 23 | # file: D://a.log 24 | #最低输出日志等级 25 | # level: 26 | #如果下写法在level中可以配置某个类的最低输出日志等级 27 | # com.zx.LoggerTest: debug 28 | ~~~ 29 | * 也可以直接在resources文件夹下添加logback-spring.xml文件，配置日志 30 | 31 | #### 实体类getter/setter/toString方法的省略 32 | 该框架并非程序运行时动态添加，而是打包时添加到class文件中的,所以不会对性能产生影响 33 | * 在pom.xml中引入lombok jar(SpringBoot中似乎很多jar都可以不写version): 34 | ~~~ 35 | 36 | org.projectlombok 37 | lombok 38 | 39 | ~~~ 40 | * 然后在IDEA中安装插件lombok,Eclipse去lombok官网下载jar，安装到eclipse中即可 41 | * 然后在实体类上写上注释 42 | ~~~ 43 | @Data ：注解在类上；提供类所有属性的 getting 和 setting 方法，此外还提供了equals、canEqual、hashCode、toString 方法 44 | @Setter：注解在属性上；为属性提供 setting 方法 45 | @Getter：注解在属性上；为属性提供 getting 方法 46 | @Log4j ：注解在类上；为类提供一个 属性名为log 的 log4j 日志对象 47 | @@Slf4j:注解在类上，为类提供一个 属性名为log的slf4j日志对象 48 | @NoArgsConstructor：注解在类上；为类提供一个无参的构造方法 49 | @AllArgsConstructor：注解在类上；为类提供一个全参的构造方法 50 | ~~~ 51 | 52 | #### BeanUtils工具类的使用 53 | * 可以将A实体类中所有和B实体类中属性名相同的属性的值复制到B，注意，Null值也会被复制过去 54 | * 当含有util.Date属性时，尤其是util.Date为null时，会出错;其子类sql.util是可以被支持的 55 | 56 | #### CollectionUtils类的使用 57 | * 可以判断集合是否为空或者元素为0，以及是否包含某些元素等 58 | 59 | #### timestamp格式在从数据库取出转为date后，是ms（毫秒）格式，如果需要返回的是s（秒），也就是需要除以1000 60 | * 可以构造一个类，继承JsonSerializer类，然后重写serializer()方法，在该方法中将date.getTime()/1000 61 | * 然后在被转换的实体类的对应Date属性上，加上@JsonSerializer(using=类名.class)注解即可 62 | * 这样的作用是SpringMVC把后台实体类转为JSON返回给前端时，对T类型的数据进行特殊的操作 63 | * 详见Date2LongSerializer类和OrderDTO类 64 | 65 | * 自己写了个String2TestStringSerializer类，实现了将返回的String属性末尾都加上了一串字符串 66 | 67 | #### SpringMVC，在要返回成JSON的实体类上+ @JsonInclude(JsonInclude.Include.NON_NULL)注解，不会返回空对象 68 | * 也可以直接在yml文件中作 spring:jackson:default-property-inclusion: non_null的全局配置，不用加注解 69 | * 如果需要返回默认的值，可以直接在实体类中给对应属性赋初始值 70 | 71 | #### 微信开发可以使用https://github.com/wechat-group/weixin-java-tools该项目上的依赖 72 | 73 | #### 枚举类 74 | 如果需要枚举类拥有相同的属性，可以定义一个接口； 75 | 例如一个A接口定义了getCode()和getMessage()方法； 76 | 那么所有实现该接口的枚举类都需要定义code和message属性； 77 | 然后可以写工具类，一个泛型方法，可以对实现该接口的所有枚举，通过code返回对象 78 | 79 | #### 分布式系统：物理架构中不共享主内存，通过网络发送消息合作 80 | * 多节点 81 | * 消息通信 82 | * 不共享内存 83 | * 集群是指同一服务多节点；分布式是不同服务多节点 84 | 85 | #### 分布式session 86 | * 登录时生成一个token，存入redis和cookie 87 | * 登出时删除用户的cookie即可 88 | 89 | * 可以使用spring mvc中的aop来进行登录校验 90 | * 如果失败可以抛出指定异常 91 | * 然后定义SpringMVC的ExceptionHandler，在其中指定处理该异常，跳转到登录页面 92 | * @ResponseStatus注解可以返回给前端指定的HTTP状态码 93 | * 在被@ControllerAdvice注解的异常处理类中，也可以直接返回ModelAndView等；包括@ResponseBody等注解都可以使用 94 | * 所以可以在其他位置抛出对应的AException，然后定义一个AException处理方法，将对应的错误码和错误信息直接返回给前端 95 | 96 | #### Apache ab 压测工具 简单的语句即可，非常方便 97 | 98 | #### Redis实现分布式锁 99 | ~~~ 100 | //可以直接注入这个对象redisTemplate.opsForValue()获取的对象 101 | @Autowired 102 | ValueOperations valueOperations;
