SpringMVC，Controller的返回页面类型以及路径设置默认值

一般设置在spring-servlet.xml里面设置

<!-- 对转向页面的路径解析。prefix：前缀， suffix：后缀 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsp/"/>
<property name="suffix" value=".jsp"/>
</bean>

@RequestMapping(value="/appAuthCallBack")
    public String redirect(HttpServletRequest request,HttpSession session, ModelMap model){
        String authCode=request.getParameter("auth_code");
        LoggerUtil.info(logger, "回调入参：{0}", authCode);
        Map<String, String> map=payservice.getAccessToken(authCode);//获取accessToken
        session.setAttribute("accessToken", map.get("accessToken"));
        session.setAttribute("userId", map.get("userId"));
        LoggerUtil.info(logger, "获取map的值：{0}", map);
        model.addAttribute("userId", map.get("userId"));
        model.addAttribute("accessToken", map.get("accessToken"));
        return "showtoken.vm";
    }

设置生效时不管返回前缀后缀是什么都会加上路径前缀和后缀
