spring MVC 拦截器怎么获取controller返回值

[揍敌客小强]

使用springMVC拦截器需要实现3个方法，分别是preHandle、afterCompletion、postHandle

postHandle是controller返回后调用的，获取controller返回的值，


@RequestMapping(value = "/goSetBank")
public ModelAndView gotoBind() {

ModelAndView mv = new ModelAndView();
mv.addObject("webAddr", webAddr);

return mv;
}
ModelAndView .getModel();可以获取上面这种情况的返回值，但是下面这种要怎么获取？

@ResponseBody
@RequestMapping(value = "/marginStep0")
public Map<String, Object> marginStep0() {
Map<String, Object> resMap = new HashMap<String, Object>();



return resMap;
}

怎么获取resMap

直接弄不了，自己写aop吧

[龙兴江]

resMap。getName()啊

[李德胜1995]

用AOP使用@AfterReturning可以得到

楼主解决了么？解决方法可以分享下吗？

[揍敌客小强]

Map<String, Object> resMap1 = (Map<String, Object>) request.getAttribute("resMap"); 这样就可以获取到了

@Aspect @Component public class CreditApplyAspect { @Around("execution(* com.wandaph.api.standard.rest.*.creditApply(..))") public Object handleControllerMethod(ProceedingJoinPoint pjp) throws Throwable { StringBuffer key = new StringBuffer(); Integer failTimes = null; Object[] args = pjp.getArgs(); CreditApplyDto dto = null; for (Object arg : args) { if(arg instanceof CreditApplyDto){ dto = (CreditApplyDto)arg; }else if(arg instanceof HttpServletRequest){ HttpServletRequest request = (HttpServletRequest)arg; dto = ResponseUtil.getRequestData(request,CreditApplyDto.class); } .... } Object object = pjp.proceed(); .... return object; } } Controller方法: @RequestMapping(value="/creditApply",method = RequestMethod.POST) public ApiResult creditApply(HttpServletRequest request){ ...... }
