1.在pom.xml下导入依赖包

（1）Spring四个核心依赖包

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

（2）SpringMVC依赖包

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

（3）数据库连接包

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

待补充.........

依赖包版本号设置

    <properties>
        <!-- 进行相关插件的属性定义 -->
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <maven.compiler.source>1.10</maven.compiler.source>
        <maven.compiler.target>1.10</maven.compiler.target>
        <maven-compiler-plugin.version>3.8.1</maven-compiler-plugin.version>
        <!-- 定义profile的相关处理 -->
        <profiles.dir>src/main/profiles</profiles.dir>   <!-- 定义profiles父路径 -->
        <resources.dir>src/main/resources</resources.dir>   <!-- 定义resources父路径 -->
        <!-- 定义依赖库的版本编号 -->
        <spring.version>5.1.7.RELEASE</spring.version>
        <junit.version>4.12</junit.version>
        <javax.annotation-api.version>1.3.2</javax.annotation-api.version>
        <mysql.version>5.1.47</mysql.version>
    </properties>

2.在子pom.xml下导入依赖包

3.在spring/spring-mvc.xml下设置扫描路径

       <context:component-scanbase-package="com.lion.service,com.lion.dao,com.lion.vo" />
       <context:component-scan base-package="com.lion.service.Impl,com.lion.dao.Impl" />
       <context:component-scan base-package="com.lion.action"/>
       <mvc:annotation-driven/>
       <mvc:default-servlet-handler/>  <!-- 使用之前配置的DispatcherServlet类处理请求 -->

4.配置spring-mvc.xml，添加bean

<bean id="memberSource" class="org.springframework.context.support.ResourceBundleMessageSource" >
       <property name="basenames">
                 <array>
                        <value>com.lion.member.pages</value>
                  </array>
        </property>
</bean>

5.配置WEB-INF下前缀与后缀匹配路径

<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
              <property name="prefix" value="/WEB-INF/pages/"/>   <!-- 路径前缀配置 -->
              <property name="suffix" value=".jsp"/> <!-- 匹配路径后缀 -->
       </bean>

6.把所有的webapp页面目录下网页文件移动到WEB-INF目录下，

（1）bootstrap

（2）css

（3）imags

（4）js

（5）lib

（6）pags

7.添加过滤的基本配置文件路径到webapp目录下的web.xml目录下

 <!-- 1、SpringMVC本身是运行在Spring容器之中，所以需要定义一个Spring容器的基本配置文件路径 -->
    <context-param> <!-- 配置全局的初始化参数，这个参数依靠ServletContext.getInitParameter()获取 -->
        <param-name>contextConfigLocation</param-name>  <!-- 属性标准名称 -->
        <!-- 所有的Spring配置文件只允许加载一次，不要重复加载 -->
        <param-value>classpath:spring/spring-mvc.xml</param-value>
    </context-param>
    <!-- 2、通过WEB容器启动的时候实现Spring容器的启动操作 -->
    <listener>
        <listener-class>
            org.springframework.web.context.ContextLoaderListener
        </listener-class>
    </listener>
    <!-- 3、配置SpringMVC的分发处理Servlet，利用此Servlet找到所有的Action -->
    <servlet>
        <servlet-name>SpringMVCServlet</servlet-name>
        <servlet-class>
            org.springframework.web.servlet.DispatcherServlet
        </servlet-class>
        <!-- 此时配置的是SpringMVC的启动文件，该配置文件不要重复的加载 -->
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:spring/spring-mvc.xml</param-value>
        </init-param>
    </servlet>
    <servlet-mapping>
        <servlet-name>SpringMVCServlet</servlet-name>
        <!--<url-pattern>*.action</url-pattern>现在不适用action也可以--> <!-- 设置扫描的访问处理路径 -->
        <url-pattern>/</url-pattern>
    </servlet-mapping>
    <!-- 4、配置项目中的编码过滤器 -->
    <filter>
        <filter-name>EncodingFitler</filter-name>
        <filter-class>
            org.springframework.web.filter.CharacterEncodingFilter
        </filter-class>
        <init-param>
            <param-name>encoding</param-name>
            <param-value>UTF-8</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>EncodingFitler</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
</web-app>

8.在spring-web目录下的资源文件resources创建配置的页面资源文件 pages.properties,例如：resources/com/lion/member/pages/pages.properties

member.add.page = admin/member/member_add
member.delete.page = admin/member/member_delete_do
member.edit.page = admin/member/member_edit
member.list.page = admin/member/member_list

9.在index.jsp页面设置跳转路径

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>Title</title>
</head>
<body>
<jsp:forward page="/pages/admin/member/list"></jsp:forward>   //设置初始跳转路径
</body>
</html>

10.在数据层xxxDAOImpl中添加注解  “@Repository” ；

11.在业务层xxxServiceImpl中添加注解  “@Service” ；

12.在控制层设置跳转路径，不在jsp页面传参了，可以在业务层传参，设置参数

@Controller
@RequestMapping("/pages/admin/member/*")
public class MemberAction extends AbstractAction {
    @RequestMapping("list")
    public ModelAndView list() {
        System.out.println("Hello");
        ModelAndView mav  = new ModelAndView("admin/member/member_list");
        return  mav;
    }
}

相对应的JSP页面路径

<html>
<head>
    <jsp:include page="/pages/plugins/basepath.jsp"/>
    <jsp:include page="/pages/plugins/common.jsp"/>
    <script type="text/javascript" src="js/admin/member/member_add.js"></script>
</head>
<body>

component-scan
