Intellij IDEA中使用MyBatis-generator 自動生成MyBatis程式碼

1、在idea中安裝MyBatis-generator外掛,點選 File -> Settings -> Plugins，輸入mybatis-generator找到這個外掛，如下圖

2、建立一個maven工程，此過程略

3、在pom檔案中新增以下程式碼

<dependencies>
    <!-- mybatis -->
    <!-- https://mvnrepository.com/artifact/org.mybatis/mybatis 
 
-->
    <dependency>
      <groupId>org.mybatis</groupId>
      <artifactId>mybatis</artifactId>
      <version>3.4.2</version>
    </dependency>

    <!-- mybatis整合spring 的適配包 -->
    <!-- https://mvnrepository.com/artifact/org.mybatis/mybatis-spring 
 
-->
    <dependency>
      <groupId>org.mybatis</groupId>
      <artifactId>mybatis-spring</artifactId>
      <version>1.3.1</version>
    </dependency>

    <!-- mybatis逆向工程 -->
    <!-- https://mvnrepository.com/artifact/org.mybatis.generator/mybatis-generator-core 
 
-->
    <dependency>
      <groupId>org.mybatis.generator</groupId>
      <artifactId>mybatis-generator-core</artifactId>
      <version>1.3.2</version>
    </dependency>

  </dependencies>

  <build>
    <finalName>generator</finalName>
    <plugins>
      <!--mybatis 逆向工程外掛-->
      <plugin>
        <groupId>org.mybatis.generator</groupId>
        <artifactId>mybatis-generator-maven-plugin</artifactId>
        <version>1.3.2</version>
        <configuration>
          <configurationFile>${basedir}/src/main/resources/generatorConfig.xml</configurationFile>
          <overwrite>false</overwrite>
          <verbose>true</verbose>
        </configuration>
        <dependencies>
          <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>5.1.38</version>
          </dependency>
        </dependencies>
      </plugin>
    </plugins>

4、在resources中建立generatorConfig.xml 

<?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>

    <context id="DB2Tables" targetRuntime="MyBatis3">
        <commentGenerator>
            <!-- 是否去除自動生成的註釋 true：是 ： false:否 -->
            <property name="suppressAllComments" value="true" />
            <!-- 是否去除所有自動生成的檔案的時間戳，預設為false -->
            <!-- <property name="suppressDate" value="false"/> -->
        </commentGenerator>
        <!-- 配置資料庫連線 -->
        <jdbcConnection driverClass="com.mysql.jdbc.Driver"
                        connectionURL="jdbc:mysql://localhost:3306/資料庫名?useSSL=true"
                        userId="root"
                        password="root">
        </jdbcConnection>
        <!--Oracle資料庫的連線資訊-->
        <!-- <jdbcConnection driverClass="oracle.jdbc.OracleDriver"
            connectionURL="jdbc:oracle:thin:@127.0.0.1:1521:yycg"
            userId="yycg"
            password="yycg">
        </jdbcConnection> -->

        <!-- 預設false，把JDBC DECIMAL 和 NUMERIC 型別解析為 Integer，為 true時把JDBC DECIMAL 和
             NUMERIC 型別解析為java.math.BigDecimal -->
        <javaTypeResolver>
            <property name="forceBigDecimals" value="false" />
        </javaTypeResolver>

        <!-- 指定javaBean生成的位置 -->
        <!-- targetPackage:包名稱(自定義)  targetProject：專案路徑(自定義)   -->
        <javaModelGenerator targetPackage="com.xhanglog.entity"
                            targetProject=".\src\main\java">
            <!-- enableSubPackages:是否讓schema作為包的字尾 -->
            <property name="enableSubPackages" value="true" />
            <!-- 從資料庫返回的值被清理前後的空格  -->
            <property name="trimStrings" value="true" />
        </javaModelGenerator>

        <!--指定sql對映檔案生成的位置 -->
        <sqlMapGenerator targetPackage="mapper"
                         targetProject=".\src\main\resources">
            <property name="enableSubPackages" value="true" />
        </sqlMapGenerator>

        <!-- 指定dao介面生成的位置，mapper介面 -->
        <javaClientGenerator type="XMLMAPPER"
                             targetPackage="com.xhanglog.dao"
                             targetProject=".\src\main\java">
            <property name="enableSubPackages" value="true" />
        </javaClientGenerator>


        <!-- table指定每個表的生成策略 domainObjectName="Abnormal"-->
        <table tableName="artical" ></table>
        <table tableName="tag" ></table>
        <table tableName="member" ></table>
        <table tableName="link" ></table>
        <table tableName="comment" ></table>
    </context>
</generatorConfiguration>

 5、點選 Maven Projects -> mybatis-generator,如下圖所示

 6，執行後的目錄結構如下
