Spring AOP中如何获取HttpServletResponse?

Question

//ServletRequestAttributes may be null, check it first.
HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest();
这样试试

Answer 1

@defondes
我是想要response啊
不是request...
我想回写cookie...

Answer 2

sorry，看看这个
@Aspect
public class MyAspect {    private Logger logger = LoggerFactory.getLogger(this.getClass());    @Pointcut("execution(public * com..controller.*Controller.*(..)) &&" +
            "!execution(public * com..NotThisController.*(..))") 
    private void pointCut(){} 
    
    @Before("pointCut()")
public void beforeInit() throws Throwable {
     ServletWebRequest servletContainer = (ServletWebRequest)RequestContextHolder.getRequestAttributes();
     HttpServletRequest request = servletContainer.getRequest();
     HttpServletResponse response = servletContainer.getResponse();
//do something
}
    @After("pointCut()")
public void afterInit() throws Throwable {
     ServletWebRequest servletContainer = (ServletWebRequest)RequestContextHolder.getRequestAttributes();
     HttpServletRequest request = servletContainer.getRequest();
     HttpServletResponse response = servletContainer.getResponse();
             //do something
}
}

Answer 3

ServletWebRequest servletContainer = (ServletWebRequest)RequestContextHolder.getRequestAttributes();
这个会抛异常:
error is java.lang.ClassCastException: org.springframework.web.context.request.ServletRequestAttributes cannot be cast to org.springframework.web.context.request.ServletWebRequest
我开题的时候已经说明了...
我的springMVC版本是 3.0.5.RELEASE

Answer 4

这样试试HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest();
ServletWebRequest servletWebRequest=new ServletWebRequest(request);
HttpServletResponse response=servletWebRequest.getResponse();

Answer 5

就没人在aop里写cookie吗
除了参数注入或者ThreadLocal就没别的办法？

Answer 6

你可以写一个Filter  然后把Response 放在Reqeuest-Scoped的Bean里面
