spring拦截器学习小结

为了实现网站的日志管理,研究了几天的spring事务管理终于OK了!两种方法

方法一:实现对目标类进行拦截(对于有接 口 的类,使用的是Java内部类提供的Proxy;而对于那些不实现接口 的类,使用的是cglib库)

xml 代码

 <!-- Bean configuration -->
    < bean   id = "businesslogicbean"
     class = "org.springframework.aop.framework.ProxyFactoryBean" >
       < property   name = "proxyInterfaces" >
          < value > IBusinessLogic </ value >
       </ property >
       < property   name = "target" >
          < ref   local = "beanTarget" />
       </ property >
       < property   name = "interceptorNames" >
          < list >
             < value > theAroundAdvisor </ value >
          </ list >
          </ property >
    </ bean >
    <!-- Bean Classes -->
    < bean   id = "beanTarget"
     class = "com.safetys.service.UserService" />

    <!-- Advisor pointcut definition for around advice -->
    < bean   id = "theAroundAdvisor"
        class = "org.springframework.aop.support.RegexpMethodPointcutAdvisor" >
       < property   name = "advice" >
          < ref   local = "theAroundAdvice" />
       </ property >
       < property   name = "pattern" >
          < value > .* </ value >
       </ property >
    </ bean >

    <!-- Advice classes -->
    < bean   id = "theAroundAdvice"
        class = "com.safetys.iface.TestBeforeAdvice" />

 

方法二:拦截ACTION(我现在用的就是这方法)

xml 代码

 < bean   id = "actionBeanNameProxyCreator"
 class = "org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator" >
 < property   name = "beanNames" > < value > *Action </ value > </ property >
 < property   name = "interceptorNames" >
 < list >
 < value > theBeforeAdvice </ value >
 </ li  st >
 </ property >
 </ bean >
 < bean   id = "theBeforeAdvice"   class = "com.safetys.iface.TestBeforeAdvice" />
