Question

我正在尝试使用hello world示例测试spring mvc框架。我创建了控制器并配置了bean和web.xml文件（你会发现代码如下），但我不知道为什么当我做了response.sendRedirect（＆＃34; / hello＆＃34;）我得到了这个错误资源不可用。这是我的代码：

我的控制器

@Controller

public class TestController {


    @RequestMapping("/hello")  
    public ModelAndView helloWorld() {  

        String message = "HELLO SPRING MVC";  
        return new ModelAndView("test", "message", message);  
    }  
}

我的spring-servlet.xml位于WEB-INF

下

<?xml version="1.0" encoding="UTF-8"?>
<beans  xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"

    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">  
        <property name="prefix" value="/WEB-INF/jsp/" />  
        <property name="suffix" value=".jsp" />  
    </bean>  
</beans>

我的web.xml
