在dao层中引入entity-module模块

 

 

 

如上图操作,在service层引入 entity和dao层

在action层引入entity层和dao层

 

 

将web层下的src目录删除，因为用不着

 

 

 在web层的 pom目录中

 

 

 然后新建resources资源目录，以及webapp网页资源目录

紧接着，在web目录的pom文件继续添加

<build>
         <resources>
             <resource>
                 <directory>resources</directory>
             </resource>
         </resources>
         <plugins>
             <plugin>
                 <groupId>org.apache.maven.plugins</groupId>
                 <artifactId>maven-war-plugin</artifactId>
                 <version>3.2.2</version>
                 <configuration>
                     <webResources>
                         <resource>
                             <directory>webapp</directory>
                         </resource>
                     </webResources>
                 </configuration>
             </plugin>
         </plugins>
     </build>

在webapp目录下新建WEB-INF在WEB-INF目录下新建web.xml，插入如下代码

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1">

    <!--这是springmvc的配置-->
    <servlet>
        <servlet-name>springmvc</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:springmvc.xml</param-value>
        </init-param>
    </servlet>

    <servlet-mapping>
        <servlet-name>springmvc</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

    <!--这是spring的配置-->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext.xml</param-value>
    </context-param>
    <!-- Spring监听器 -->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    <!-- 字符编码过滤器 -->
    <filter>
        <filter-name>CharacterEncodingFilter</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>CharacterEncodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
    <!-- 允许返回html视图 -->
    <servlet-mapping>
        <servlet-name>default</servlet-name>
        <url-pattern>*.html</url-pattern>
    </servlet-mapping>
</web-app>

在resources新建applicationContext.xml、jdbc.properties、springmvc.xml

分别插入如下代码

applicationContext.xml

 

<?xml version="1.0" encoding="UTF-8"?>

emm，说实话我觉得这篇文章写得相对乱，唉，不管了，反正就是贴代码，反正只是怕自己忘记，你们的想法不重要

 

https://github.com/Loudsa/student 项目已经提交GitHub，想试试的朋友可以看下，
