初始化配置

1、Maven配置

先說Maven的項目依賴配置文件pom.xml，我們進入mvn repository 查找需要搜索的包結果如圖：

點擊進入第一個搜索結果，然後各種版本

點擊所需版本。如圖：

裏面的dependency即爲所需標籤。

2、web配置

web.xml配置添加如下信息：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
         id="ssm" version="2.5">

  <!-- 初始化spring容器 -->
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:applicationContext.xml</param-value>
  </context-param>
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>


  <!-- 解決post亂碼 -->
  <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>

  <!-- 解決jsp include html 亂碼問題 -->
  <jsp-config>
    <jsp-property-group>
      <description>html encoding</description>
      <display-name>JSPConfiguration</display-name>
      <url-pattern>*.html</url-pattern>
      <el-ignored>true</el-ignored>
      <page-encoding>UTF-8</page-encoding>
      <scripting-invalid>false</scripting-invalid>
      <include-prelude></include-prelude>
      <include-coda></include-coda>
    </jsp-property-group>
  </jsp-config>

  <!-- springmvc的前端控制器 -->
  <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>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>springmvc</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>
</web-app>

使用spring框架的默認DispatcherSerlet。load-on-starup標籤表示servlet的啓用時間，servlet-name指定了serevlet配置文件myspring。url -pattern是指所有路徑均會被該servlet攔截。而filter一句是防止中文亂碼，啓用uft-8。

配置Servlet springmvc.xml

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

配置mybatis-config.xml

"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>

   <settings>
      <setting name="cacheEnabled" value="true" />
   </settings>
</configuration>

配置jdbc.properties

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://127.0.0.1:3306/ssm?useUnicode=true&characterEncoding=utf-8
jdbc.username=root
jdbc.password=root

配置log4j.properties

# Global logging configuration\uff0c\u5efa\u8bae\u5f00\u53d1\u73af\u5883\u4e2d\u8981\u7528debug

log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%5p [%t] - %m%n

使用MyBatis Generator逆向工程生成代碼

配置jdbc.properties

1、配置Maven pom.xml 文件

在pom.xml增加以下插件：

配置好Maven插件，下面需要配置插件需要配置文件

二、在maven項目下的src/main/resources 目錄下建立名爲 Maven的項目配置文件存放路徑如下圖：generatorConfig.xml和jdbc.properties配置文件，

Maven的項目配置文件存放路徑如下圖：

generatorConfig.xml代碼如下：

配置jdbc.properties

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE generatorConfiguration PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN" "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd" >
<generatorConfiguration>
    <properties resource="jdbc.properties"></properties>
    <classPathEntry
        location="E:\npm\react4pe\workspace\SSMTestProject\src\main\webapp\WEB-INF\lib\mysql-connector-java-5_1_.1.6-bin.jar" />
    <context id="context1" targetRuntime="MyBatis3">
        <!-- 序列化pojo -->
        <plugin type="org.mybatis.generator.plugins.SerializablePlugin" />
        <commentGenerator>
            <property name="suppressDate" value="true" />
            <property name="suppressAllComments" value="true" />
        </commentGenerator>
        <!--<jdbcConnection driverClass="com.mysql.jdbc.Driver"
            connectionURL="jdbc:mysql://localhost:3306/ssm?characterEncoding=utf-8"
            userId="root" password="root" />-->


        <jdbcConnection driverClass="${jdbc.driver}" connectionURL="${jdbc.url}" userId="${jdbc.username}" password="${jdbc.password}">
        </jdbcConnection>
        <!--指定生成的實體類-->
        <!-- Model模型生成器,用來生成含有主鍵key的類，記錄類 以及查詢Example類
        targetPackage     指定生成的model生成所在的包名
            targetProject     指定在該項目下所在的路徑-->
        <javaModelGenerator targetPackage="com.dyq.model"
            targetProject="src\main\java" />

        <sqlMapGenerator targetPackage="com.dyq.dao"
            targetProject="src\main\java" />
        <javaClientGenerator targetPackage="com.dyq.dao"
            targetProject="src\main\java" type="XMLMAPPER" />
        <table schema="" tableName="user">
            <!-- 實體類中的成員變量和表的列明一一對應 -->
           <property name="useActualColumnNames" value="true"/>
        </table>
    </context>
</generatorConfiguration>

3、在 IDEA添加一個“Run運行”選項，使用maven運行mybatis-generator-maven-plugin插件

點擊 菜單run中Edit Configurations,會出現

點擊+號，選擇maven，會出現

配置jdbc.properties

在name和Commond line分別填上如上圖所示，apply和ok

最後點擊run，生成model，mapper，dao

測試
