(转载)spring AOP获得session
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Spring AOP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，Spring AOP中获得Session对象。
//这个是保存request和session的类public class SysContent {private static ThreadLocal<HttpServletRequest> requestLocal = new ThreadLocal<HttpServletRequest>();private static ThreadLocal<HttpServletResponse> responseLocal = new ThreadLocal<HttpServletResponse>();public static HttpServletRequest getRequest() {return (HttpServletRequest) requestLocal.get();}public static void setRequest(HttpServletRequest request) {requestLocal.set(request);}public static HttpServletResponse getResponse() {return (HttpServletResponse) responseLocal.get();}public static void setResponse(HttpServletResponse response) {responseLocal.set(response);}public static HttpSession getSession() {return (HttpSession) ((HttpServletRequest) requestLocal.get()).getSession();}}//这个是配置的过滤器public class GetContent implements Filter {@Overridepublic void destroy() {// TODO Auto-generated method stub}@Overridepublic void doFilter(ServletRequest arg0, ServletResponse arg1,FilterChain arg2) throws IOException, ServletException {SysContent.setRequest((HttpServletRequest) arg0);SysContent.setResponse((HttpServletResponse) arg1);arg2.doFilter(arg0, arg1);}@Overridepublic void init(FilterConfig arg0) throws ServletException {// TODO Auto-generated method stub}}//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@Aspectpublic Class AopTest{@Around(value="execution(* com.aptech.service.*.*(..))")public void aroundTest(ProceedingJoinPoint pj) throws Exception { HttpServletRequest request = SysContent.getRequest(); HttpServletResponse response = SysContent.getResponse(); HttpSession session = SysContent.getSession(); //其他操作 if(true){ pj.proceed(); } throw new Exception("您没有该权限"); } }
