gwt + spring通过aop记录日志获取request、session

86530499 2012-04-25

由于Spring的AOP面向切面编程,与Servlet容器没有任何关联,所以想要获得Session会话比较麻烦。

当然Struts2同样不依赖Servlet容器,可以在SpringAOP中可以使用com.opensymphony.xwork2.ActionContext,就可以获得Session。

但是在Servlet中或struts1中,可以通过ThreadLocal方式将session保存,SpringAOP中获得Session对象。

具体思路和代码:

这个是保存request和session的类

/**

*

*@author株洲健坤北大青鸟周钢

*

*/

publicclassSysContent{

privatestaticThreadLocal<HttpServletRequest>requestLocal=newThreadLocal<HttpServletRequest>();

privatestaticThreadLocal<HttpServletResponse>responseLocal=newThreadLocal<HttpServletResponse>();

publicstaticHttpServletRequestgetRequest(){

return(HttpServletRequest)requestLocal.get();

}

publicstaticvoidsetRequest(HttpServletRequestrequest){

requestLocal.set(request);

}

publicstaticHttpServletResponsegetResponse(){

return(HttpServletResponse)responseLocal.get();

}

publicstaticvoidsetResponse(HttpServletResponseresponse){

responseLocal.set(response);

}

publicstaticHttpSessiongetSession(){

return(HttpSession)((HttpServletRequest)requestLocal.get()).getSession();

}

}

这个是配置的过滤器

/**

*

*@author株洲健坤北大青鸟周钢

*

*/

publicclassGetContentimplementsFilter{

@Override

publicvoiddestroy(){

//TODOAuto-generatedmethodstub

}

@Override

publicvoiddoFilter(ServletRequestarg0,ServletResponsearg1,

FilterChainarg2)throwsIOException,ServletException{

SysContent.setRequest((HttpServletRequest)arg0);

SysContent.setResponse((HttpServletResponse)arg1);

arg2.doFilter(arg0,arg1);

}

@Override

publicvoidinit(FilterConfigarg0)throwsServletException{

//TODOAuto-generatedmethodstub

}

}

使用AOP进行环绕通知切入所有com.aptech.service包下的所有类的方法

/**

*@author株洲健坤北大青鸟周钢

*/

@Aspect

publicClassAopTest{

@Around(value="execution(*com.aptech.service.*.*(..))")

publicvoidaroundTest(ProceedingJoinPointpj)throwsException{

HttpServletRequestrequest=SysContent.getRequest();

HttpServletResponseresponse=SysContent.getResponse();

HttpSessionsession=SysContent.getSession();

//其他操作

if(true){

pj.proceed();

}

thrownewException("您没有该权限");

}

}
