  • Spring总结--> 第二结 SpringAOP日志

    SpringAOP日志记录一下，代码就贴完整代码，一劳永逸。

    SpringAOP面向切面编程，拦截指定代码，对该代码进行增强。

    SpringAOP实现日志很简单

    • 第一种方式配置XML文件
      • 在Spring的XML文件中配置拦截
      • 定义增强代码就OK了
      • 运行结果
        •  
    • 第二种方式注解
      • 配置Spring.xml文件 
        • 1 <!-- 声明自动为spring容器中那些配置@aspectJ切面的bean创建代理 -->
2 <aop:aspectj-autoproxy proxy-target-class="true" />
      • 定义增强代码 
        •  1 package com.xxw.util;

48         String targetName = joinPoint.getTarget().getClass().getName();
49         // 获取方法名
50         String methodName = joinPoint.getSignature().getName();

52         SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
