自定义注解，结合AOP实现日志功能
在做AOP日志的的时候，注意：
<aop:aspectj-autoproxy proxy-target-class=”true”/>
如果将上面的话放在spring-context.xml/applicationContext.xml中，这里的aop设置将不会生效！！
源代码下载地址：

代码以下

import java.lang.annotation.Documented;
import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;
@Retention(RetentionPolicy.RUNTIME)//注解会在class中存在，运行时可通过反射获取
@Target(ElementType.METHOD)//目标是方法
@Documented//文档生成时，该注解将被包含在javadoc中，可去掉
public @interface OpLogger {
