Spring MVC:DispatcherServlet中没有名称为mvc-dispatcher的映射

Question

我是Spring新手,当我尝试使用以下URL访问我的应用程序时,我收到错误消息 - DispatcherServlet中没有名称为mvc-dispatcher的映射

http://localhost:8090/springexample/helloWorld

1.web.xml

<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>

2.mvc - 调度 - servlet.xml中

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

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

3.HelloWorldController

package com.test;

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("/helloWorld")
public class HelloWorldController {

        @RequestMapping(method = RequestMethod.GET)
        public String hello(ModelMap model) {

            model.addAttribute("name", "Hello World!");
            return "helloWorld";

        }

    }

4.pom.xml

  <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-core</artifactId>
            <version>${spring.version}</version>
        </dependency>

        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-webmvc</artifactId>
            <version>${spring.version}</version>
        </dependency>
  </dependencies>
<properties>
        <spring.version>4.0.2.RELEASE</spring.version>
    </properties>

Answer 1

你错过了

<mvc:annotation-driven />

以及servlet上下文中相应的名称空间声明.

没有它,将为您生成一个默认的MVC堆栈,其中不包含您的控制器.
