Spring MVC 视图问题,访问 jsp 却返回字符串,紧急求助!

  • java
  • 404错误

war 包结构如下:

spring-mvc 配置文件如下:

<?xml version="1.0" encoding="UTF-8"?>

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"

<!-- 注解扫描包 -->

<!-- 开启注解 -->

<!-- 定义跳转的文件的前后缀 ,视图模式配置-->  
<bean id="viewResolver"  
    class="org.springframework.web.servlet.view.InternalResourceViewResolver">  
    <!-- 这里的配置我的理解是自动给后面action的方法return的字符串加上前缀和后缀,变成一个 可用的url地址 -->  
    <property name="prefix" value="/WEB-INF/jsp/" />  
    <property name="suffix" value=".jsp" />  
</bean>  

<!--  配置静态资源,直接映射到对应的文件夹,不被DispatcherServlet处理,3.04新增功能,需要重新设置spring-mvc-3.0.xsd   -->

<mvc:resources mapping="/css/**" location="/css/" />

通过Controller 层访问jsp 页面,返回的是字符串“index”

但是输入jsp 以外的请求,又能正常访问:

请各位帮帮忙解答,十分感谢!!!!

对应的controller class 如下:
@Controller
public class PtestProjectController {
@Autowired
private PtestProjectService ptestprojectservice;

@RequestMapping("/project/list/{id}")
@ResponseBody
public PtestProject getProjectById(@PathVariable int id) throws Exception{
     PtestProject result = ptestprojectservice.getProjectById(id);
     return result;
    }

@RequestMapping("/index")
@ResponseBody
public String getIndex() throws Exception{
     return "index";
}
}

为什么不返回jsp页面?
