ViewResolver 不解析视图名称，而是请求 URL，Spring 3.0

Question

viewresolver 正在解析请求 url 而不是返回的视图名称，请帮帮我，因为我是 Spring 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 配置：

<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？

我也遇到了同样的问题，解决方法很简单——不用导入包

import org.springframework.web.servlet.ModelAndView;

你已经导入

import org.springframework.web.portlet.ModelAndView;

Answer 2

这是一种变通方法，但它会起作用。 执行以下操作 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);
 }

如果你在这里添加url-pattern as /home，这意味着servlet 将只映射/home 目录。 于是我们改成了/

我在添加<aop:aspectj-autoproxy/> 时遇到了类似的问题。从我的配置文件中删除它后，一切都很好。
