使用Maven搭建SpringMVC

1.创建Maven Project

注意选择webapp

2.添加Maven依赖

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <groupId>springmvctest</groupId>
    <artifactId>com.test</artifactId>
    <packaging>war</packaging>
    <version>0.0.1-SNAPSHOT</version>
    <name>com.test Maven Webapp</name>
    <url>http://maven.apache.org</url>
    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <spring.version>3.1.2.RELEASE</spring.version>
    </properties>
    <dependencies>
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>3.8.1</version>
            <scope>test</scope>
        </dependency>
        <!-- spring -->
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-webmvc</artifactId>
            <version>${spring.version}</version>
        </dependency>

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

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

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

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

        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-test</artifactId>
            <version>${spring.version}</version>
        </dependency>
        <!-- spring end -->
    </dependencies>
    <build>
        <finalName>com.test</finalName>
    </build>
</project>

注意：1.jar包下不下来解决方案：找到Maven本地仓库，删除对应文件重新下载，如果还不能下载，到网上下载jar包放在对应目录。

           2.${spring.version}对应的版本<spring.version>3.1.2.RELEASE</spring.version>

3.设置Properties

3.1.Project Facets把java改为1.7

3.2.Java Build Path 更改JRE System Library为

3.3.Java Build Path 点击Add Library；点击Server Runtime；然后...

4.配置web.xml文件

<web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
    http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
    
  <display-name>Archetype Created Web Application</display-name>
  
  <servlet>
      <servlet-name>dispatcher</servlet-name>
      <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
      <!--1.如果使用下面注释配置请将名为springContext.xml配置文件放在src/main/resources下
          2.如果注释请用dispatcher-servlet.xml放在WEB-INF下,程序默认搜索WEB-INF名为xxx-servlet.xml
            xxx为自己定义的<servlet-name>dispatcher</servlet-name>的dispatcher
        -->
         <!-- <init-param>
             <param-name>contextConfigLocation</param-name>
          <param-value>classpath*:springContext.xml</param-value> 
         </init-param> -->
      <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
      <servlet-name>dispatcher</servlet-name>
      <url-pattern>/</url-pattern>
  </servlet-mapping>
</web-app>

注意：使用classpath*把配置文件放在webapp下或者WEB-INF下程序运行不会出错（一般找不到文件），但是Controller会拦截不到。

5.配置dispatcher-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"
    xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.0.xsd">
    
    <!-- 搜索Controller包 -->
    <context:component-scan base-package="com.test"></context:component-scan>
    <!-- 视图页面配置 -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix">
            <value>/WEB-INF/views/</value>
        </property>
        <property name="suffix">
            <value>.jsp</value>
        </property>
    </bean>
</beans>

6.编写Controller代码和jsp

省略

7.配置tomcat及运行
