Question

我一直想弄清楚一整天让我烦恼的事情。我试图运行一个非常简单的SpringMVC但是webapp似乎没有找到我设置的任何控制器。任何帮助都会很棒

Web.xml中

<web-app version="2.4" 
  xmlns="http://java.sun.com/xml/ns/j2ee" 
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
  xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee 
  http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

  <servlet>
    <servlet-name>mvc-dispatcher</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> 
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>mvc-dispatcher</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping> 

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

  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/mvc-dispatcher-servlet.xml, /WEB-INF/application-context.xml</param-value>
  </context-param>

</web-app>

MVC-调度-servlet.xml中

<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"
    xsi:schemaLocation="
    http://www.springframework.org/schema/beans     
    http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
    http://www.springframework.org/schema/context 
    http://www.springframework.org/schema/context/spring-context-4.0.xsd">

    <context:component-scan base-package="com.thehit.*" />

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

应用context.xml中

<?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:context="http://www.springframework.org/schema/context"
    xmlns:tx="http://www.springframework.org/schema/tx"
    xsi:schemaLocation="http://www.springframework.org/schema/beans 
    http://www.springframework.org/schema/beans/spring-beans.xsd
    http://www.springframework.org/schema/context
    http://www.springframework.org/schema/context/spring-context-4.0.xsd
    http://www.springframework.org/schema/tx
    http://www.springframework.org/schema/tx/spring-tx-4.0.xsd" 
    default-autowire="byType">

    <context:annotation-config/>
    <context:component-scan base-package="com.thehit.*" />

    <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName" value="com.mysql.jdbc.Driver"/>
        <property name="url" value="jdbc:mysql://localhost:3307/thehit"/>
        <property name="username" value="root"/>
        <property name="password" value="Password01"/>      
    </bean> 

</beans>

HelloWorldController.java

package com.thehit.controllers;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
@Controller
@RequestMapping("/welcome")
public class HelloWorldController {

    @RequestMapping(value="/hello", method = RequestMethod.GET) 
    public String printWelcome(ModelMap model) {
        model.addAttribute("message", "Spring 3 MVC Hello World. This is HelloControllerClass.");
        return "hello"; 
    } 
}

jsp文件位于WEB-INF / pages

中

当我导航到以下地址"http://localhost:8080/TheHitWebProject/welcome"或"http://localhost:8080/TheHitWebProject/hello"时，我收到以下错误：

HTTP Status 404 -

type Status report

message

description The requested resource is not available.

Apache Tomcat/7.0.53

我知道我错过了一些基本的东西，但我已经在这里待了好几个小时而且无法弄明白。任何帮助将非常感谢

你错过了mvc：annotation-driven：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="
        http://www.springframework.org/schema/beans 
        http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">

    <mvc:annotation-driven/>

</beans>

另请注意，来自@RequestMapping的{{1}}在方法@Controller之前添加，因此网址将为：

@RequestMapping

Webapp找不到控制器
