AspectWebLog 访问Controller时会有相关日志打印

需要引入以下包

        <dependency>
            <groupId>org.aspectj</groupId>
            <artifactId>aspectjrt</artifactId>
            <version>1.6.11</version>
        </dependency>

 

主要打印 元素有

1、controller名

2、方法名

3、HTTP方法类型 post or get

4、sessionId

5、session存活时长 

6、方法执行完成时间

7、ip地址
