Java Reflect如何利用反射获取属性上的注解

@Retention(value = RetentionPolicy.RUNTIME)
@Target(value = {ElementType.METHOD,ElementType.TYPE,ElementType.FIELD,ElementType.PARAMETER} )
public @interface MyParam1 {

    String value() default "";
}

@Retention(value = RetentionPolicy.RUNTIME)
@Target(value = {ElementType.METHOD,ElementType.TYPE,ElementType.FIELD,ElementType.PARAMETER} )
public @interface MyParam2 {

    String value() default "";
}

@ControllerAdvice
@Controller
@MyAnnotation(name = "李四",age=12)
public class Test {

    @MyField1("name1")
    @MyField2("name2")
    @Value("name")
    private String name;

    @MyField1("email1")
    @MyField2("email2")
    @Value("email")
    private String email;

}
