Question

这是我的控制器

@Controller
public class UserController {

    @RequestMapping(value = "/user", method = RequestMethod.GET,headers="Accept=application/json")
    public @ResponseBody RegisterUser getUser() {
        RegisterUser registerUser = new RegisterUser();
        registerUser.setId(1);
        registerUser.setName("John");
        registerUser.setDob("15-04-1993");
        registerUser.setAddress("US");
        registerUser.setDepartment("IT");
        return registerUser;
    }
}

这是我的spring-servlet.xml文件

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

      http://www.springframework.org/schema/beans/spring-beans-4.1.xsd

      http://www.springframework.org/schema/mvc
      http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">


    <context:component-scan base-package="com.user.test" />
    <bean
        class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/view/" />
        <property name="suffix" value=".jsp" />
    </bean>
</beans>

这是我的web.xml文件

<web-app>
    <display-name>Archetype Created Web Application</display-name>
    <servlet>
        <servlet-name>spring</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>spring</servlet-name>
        <url-pattern>/*</url-pattern>
    </servlet-mapping>
    </web-app>

当我收到用户详细信息时，我的提前休息客户端出现了404错误。我在控制台窗口中收到的错误是：

2017年1月8日下午3:02:18 org.springframework.web.servlet.PageNotFound handleNoSuchRequestHandlingMethod警告：没有匹配的处理程序方法找到servlet请求：路径＆＃39; / user＆＃39;，方法＆＃39; GET＆＃39;，参数地图[[空]]

Your web.xml is not complete

**Add the following into your web.xml which creates Spring Container shared by all Servlets and Filters**


    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <servlet>
        <servlet-name>spring</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>/WEB-INF/spring/spring-servlet.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
