Question

viewresolver正在解析请求url而不是返回的视图名称，在这里帮助我，因为我是Spring的新手

日志显示：

MethodName : springController()

ClassName : ModelAndView: reference to view with name 'StartPage'; model is {message=Hey welcome to Spring 3.0!! }
-------------------------------------------------------------------------------
MethodName : springContoller

Invoking afterPropertiesSet() on bean with name 'home'
Rendering view [org.springframework.web.servlet.view.JstlView: name 'home'; URL [/jsp/home.jsp]] in DispatcherServlet with name 'spring'
Forwarding to resource [/jsp/home.jsp] in InternalResourceView 'home'
Successfully completed request

bean config：

<bean id="viewResolver"
        class="org.springframework.web.servlet.view.UrlBasedViewResolver">
        <property name="viewClass"
            value="org.springframework.web.servlet.view.JstlView" />
        <property name="prefix" value="/jsp/" />
        <property name="suffix" value=".jsp" />
    </bean>

控制器：

@Controller
public class HomeController {

    @Autowired
    private ObjectMapper objmapper;

    @Autowired
    public SLogger tLogger;

    @RequestMapping("/home")
    public ModelAndView springContoller(){
        String message = "Hey welcome to Spring 3.0!! ";
        System.out.println("in controller");
        tLogger.writeToLog(HomeController.class.getName(), "springController()", Level.DEBUG);
        return new ModelAndView("StartPage","message",message);
    }
    }

不是解析为/jsp/StartPage.jsp而是解析为/jsp/home.jsp，为什么？

弹簧servlet.xml中

 <servlet>

 <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
 <load-on-startup>1</load-on-startup>
 </servlet>
 <servlet-mapping>

Answer 1

我有同样的问题，解决方案非常简单 - 而不是导入包

import org.springframework.web.servlet.ModelAndView;

您已导入

import org.springframework.web.portlet.ModelAndView;

Answer 2

这是解决方法，但它会起作用。做如下在web.xml中

 <servlet-mapping>
        <servlet-name>appServlet</servlet-name>
        <url-pattern>/</url-pattern>
 </servlet-mapping>

在你的HomeController中

//first landing controller
 //it will redirect to your home controller
 @RequestMapping(value = "/", method = RequestMethod.GET)
 public ModelAndView home() {
    return new ModelAndView("redirect:/home")
 }

 @RequestMapping("/home")
 public ModelAndView springContoller(){
    String message = "Hey welcome to Spring 3.0!! ";
    System.out.println("in controller");
    tLogger.writeToLog(HomeController.class.getName(), "springController()",
    Level.DEBUG);
    return new ModelAndView("StartPage","message",message);
 }

如果添加url-pattern as /home，这意味着servlet将仅映射/ home目录。所以我们改为/

Answer 3

我添加<aop:aspectj-autoproxy/>时遇到类似问题。从配置文件中删除后，一切都很好。

ViewResolver没有解析查看名称，而是请求URL，Spring 3.0
