Spring MVC通过添加自定义注解格式化数据的方法

@Target({ElementType.TYPE, ElementType.METHOD})  //类名或方法上@Retention(RetentionPolicy.RUNTIME)//运行时@component//自定义多个注解，且在一个类中添加两个或以上的，只需要加一个 否则会实例化多次。public @interface SocketMapping { String value() default "";//参数}

@SocketMapping("/a")public class TestAnno { @SocketMapping(value="/b") public void ss(){ System.out.println(11); } }

ResourcePatternResolver rpr = new PathMatchingResourcePatternResolver();   Resource[] res = rpr.getResources("classpath*:websocket/**.class");//测试类的包    for(int i=0;i<res.length;i++){  String className = res[i].getURL().getPath();  className = className.split("(classes/)|(!/)")[1];  className = className.replace("/", ".").replace(".class", "");//获取到文件结构 com.xl.joe.testAnno  Class<?> cla = Class.forName(className);//获取到文件类     if(cla.isAnnotationPresent(SocketMapping.class)){//判断是否存在自定义注解   System.out.println(cla.getAnnotation(SocketMapping.class).value());//获取自定义注解的属性值      }      Object o = SpringContextUtil.getBean("testAnno");//获取类对象      Method[] methods = cla.getMethods();//获取类的方法   for(Method method:methods){   if(method.isAnnotationPresent(SocketMapping.class)){//找到自定义注解    method.invoke(o, new Object[]{});//反射改方法   }   }    }
