IDEA中使用mybatis-generator【逆向工程】

1.在pom坐标中导入generator坐标
<!--mybatis逆向工程依赖-->
    <dependency>
      <groupId>org.mybatis.generator</groupId>
      <artifactId>mybatis-generator-core</artifactId>
      <version>1.3.7</version>
    </dependency>
2.在pom中加入generator插件
<!--逆向工程插件-->
      <plugins>
        <plugin>
          <groupId>org.mybatis.generator</groupId>
          <artifactId>mybatis-generator-maven-plugin</artifactId>
          <version>1.3.5</version>
          <dependencies>
            <dependency>
              <groupId>mysql</groupId>
              <artifactId>mysql-connector-java</artifactId>
              <version>${mysql.version}</version>
            </dependency>
          </dependencies>
          <configuration>
            <!--允许移动生成的文件-->
            <verbose>true</verbose>
            <!--允许自动覆盖文件-->
            <overwrite>true</overwrite>
            <configurationFile>src/main/resources/generatorConfig.xml</configurationFile>
          </configuration>
          <executions>
            <execution>
              <id>mybatis generator</id>
              <phase>package</phase>
              <goals>
                <goal>generate</goal>
              </goals>
            </execution>
          </executions>
        </plugin>
      </plugins>
3.在main/resource中创建generatorConfig.xml文件
<?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="mybatisGenerator" targetRuntime="MyBatis3">
        <commentGenerator>
            <!-- 是否去除自动生成的注释 true:是 : false:否 -->
            <property name="suppressAllComments" value="true" />
        </commentGenerator>
        <!--数据库连接的信息:驱动类、连接地址、用户名、密码 -->
        <jdbcConnection driverClass="com.mysql.jdbc.Driver"
                        connectionURL="jdbc:mysql://localhost:3306/ssm?
                                serverTimezone=CTT&amp;useUnicode=true&amp;characterEncoding=utf-8&amp;allowMultiQueries=true"
                        userId="root" password="root">
        </jdbcConnection>

        <!-- 默认false,把JDBC DECIMAL 和 NUMERIC 类型解析为 Integer,为 true时把JDBC DECIMAL 和
            NUMERIC 类型解析为java.math.BigDecimal -->
        <javaTypeResolver>
            <property name="forceBigDecimals" value="false" />
        </javaTypeResolver>

        <!-- targetProject:生成PO类的位置 -->
        <javaModelGenerator targetPackage="cn.wuyiz.entity"
                            targetProject="src/main/java">
            <!-- enableSubPackages:是否让schema作为包的后缀 -->
            <property name="enableSubPackages" value="false" />
            <!-- 从数据库返回的值被清理前后的空格 -->
            <property name="trimStrings" value="true" />
        </javaModelGenerator>

        <!-- targetProject:mapper映射文件生成的位置 -->
        <sqlMapGenerator targetPackage="cn.wuyiz.mapper"
                         targetProject="src/main/resources">
            <!-- enableSubPackages:是否让schema作为包的后缀 -->
            <property name="enableSubPackages" value="false" />
        </sqlMapGenerator>
        <!-- targetPackage:mapper接口生成的位置 -->
        <javaClientGenerator type="XMLMAPPER"
                             targetPackage="cn.wuyiz.mapper"
                             targetProject="src/main/java">
            <!-- enableSubPackages:是否让schema作为包的后缀 -->
            <property name="enableSubPackages" value="false" />
        </javaClientGenerator>
        <!-- 指定数据库表 -->
        <table tableName="user"
               enableCountByExample="false" enableDeleteByExample="false"
               enableSelectByExample="false" enableUpdateByExample="false"
               selectByExampleQueryId="false" />

        <!-- 有些表的字段需要指定java类型
         <table schema="" tableName="">
            <columnOverride column="" javaType="" />
        </table> -->
    </context>
</generatorConfiguration>

4.添加maven命令启动项

命令:mybatis-generator:generate
