Spring Aop 日志拦截应用
浏览数：32 /
时间：2015年06月08日
近期，一个小伙伴遇到了此需求。要解决的问题就是：
记录用户在系统的操作，通过注解来灵活控制。 注解可以对方法进行修饰，描述。 后面会将注解上描述以及方法被调用时入参记录到数据库。 同时还需要对不同的操作进行分类（插入，修改，查看，下载/上传文件之类的），记录用户，时间以及IP，客户端User-agent . 我在这里将部分实现写了出来，实际在项目中可以直接参照进行修改就可以满足以上功能。
开发环境：W7 + Tomcat7 + jdk1.7 + Mysql5
框架：spring,springmvc,hibernate
于是乎，下班后动手写了个小demo,主要使用注解实现，思路如下：
1.打算在service 层切入，所以在springmvc配置文件中排除对service层的扫描
2.在spring配置文件中扫描没有被springmvc扫描的service层，aop对其增强
3.实现注解，注解要能满足记录【方法描述，参数描述，操作类型】等等
4.对拦截到的方法进行统一处理，持久化日志
代码结构图：
1.springmvc-servlet.xml配置
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<bean class="cn.org.rapid_framework.spring.web.servlet.mvc.support.ControllerClassNameHandlerMapping" >
<!-- <property name="caseSensitive" value="true"/> -->
<!-- 前缀可选 -->
<property name="pathPrefix" value="/"></property>
<!-- 拦截器注册 -->
<property name="interceptors">

</property>
</bean>
<!-- Default ViewResolver -->
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
<property name="prefix" value="/pages"/>
<property name="suffix" value=".jsp"></property>
</bean>
</beans>2.spring配置文件中扫描service层,还有其他几个配置文件相关性不大，可以下载项目后查看。这里不再贴出

}
开启测试模式：
1.直接请求insert方法:
浏览器request to :http://bill/SpringAopLogDemo/Person/insert.do
好了，下面放开断点了。 看看控制台输出，以及数据库日志记录.
控制台：
数据库：
好了，问题到这里就差不多了。 关于AOP 相关理论，请自行查阅文档学习噢。 这里不描述了，忙着搞别的去了。 哈哈。
