mybatis-generator代码生成

mybatis-generator代码自动生成文件

1、替换本地仓库的mybatis-generator-core-1.3.2.jar
该jar是改写了源码，实现实体类根据表注释生成属性注释功能
jar放在目录：C:\Users\XXX.m2\repository\org\mybatis\generator\mybatis-generator-core\1.3.2

2、pom.xml

<build>
    <plugins>
      <plugin>
        <groupId>org.mybatis.generator</groupId>
        <artifactId>mybatis-generator-maven-plugin</artifactId>
        <version>1.3.2</version>
        <configuration>
          <configurationFile>src/main/resources/generatorConfig.xml</configurationFile>
          <verbose>true</verbose>
          <overwrite>true</overwrite>
        </configuration>
        <executions>
          <execution>
            <id>Generate MyBatis Artifacts</id>
            <goals>
              <goal>generate</goal>
            </goals>
          </execution>
        </executions>
      </plugin>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        <configuration>
          <source>1.8</source>
          <target>1.8</target>
        </configuration>
      </plugin>
    </plugins>
  </build>

  <dependencies>
    <dependency>
      <groupId>org.mybatis.generator</groupId>
      <artifactId>mybatis-generator-core</artifactId>
      <version>1.3.2</version>
    </dependency>
    <!-- mysql驱动包 -->
    <dependency>
      <groupId>mysql</groupId>
      <artifactId>mysql-connector-java</artifactId>
      <version>5.1.46</version>
    </dependency>
  </dependencies>

如果是其他数据库，如oracle，就添加该依赖就好了

3、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>
    <!-- 数据库驱动 -->
    <classPathEntry    location="src/main/resources/lib/mysql-connector-java-5.1.46.jar"/>
    <context id="mysqlTables"    targetRuntime="MyBatis3">
        <!-- JavaBean 实现 序列化 接口 -->
        <plugin type="org.mybatis.generator.plugins.SerializablePlugin"/>
        <!-- genenat entity时,生成toString -->
        <plugin type="org.mybatis.generator.plugins.ToStringPlugin" />

        <commentGenerator type="org.mybatis.generator.internal.DefaultCommentGenerator">
            <!--生成的注释包含时间戳-->
            <property name="suppressDate" value="true"/>
            <!-- 是否去除自动生成的注释 true：是 ： false:否 -->
            <property name="suppressAllComments" value="false"/>
            <!-- 生成的Java文件的编码 -->
            <property name="javaFileEncoding" value="UTF-8" />
            <!-- 格式化java代码 -->
            <property name="javaFormatter" value="org.mybatis.generator.api.dom.DefaultJavaFormatter" />
            <!-- 格式化XML代码 -->
            <property name="xmlFormatter" value="org.mybatis.generator.api.dom.DefaultXmlFormatter"/>
            <property name="beginningDelimiter" value="`"/>
            <property name="endingDelimiter" value="`"/>
        </commentGenerator>
             
        <!-- 数据库连接 -->
        <jdbcConnection driverClass="com.mysql.jdbc.Driver"
                        connectionURL="jdbc:mysql://ip地址/数据库名称?characterEncoding=utf8"
                        userId="用户名称"
                        password="密码">
        </jdbcConnection>

        <!-- 数据库类型与java类型转换: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="true"/>
        </javaTypeResolver>

        <!-- 生成Model类存放位置 -->
        <javaModelGenerator targetPackage="实体包名" targetProject="src/main/java/">
            <property name="enableSubPackages" value="true"/>
            <property name="trimStrings" value="false"/>
        </javaModelGenerator>

        <!-- 生成映射文件存放位置 -->
        <sqlMapGenerator targetPackage="mapper" targetProject="src/main/resources/">
            <property name="enableSubPackages" value="true"/>
        </sqlMapGenerator>

        <!-- 生成Dao类存放位置 -->
        <javaClientGenerator type="XMLMAPPER" targetPackage="dao包名" targetProject="src/main/java/">
            <property name="enableSubPackages" value="true"/>
        </javaClientGenerator>

        <!-- 生成对应表及类名 -->
        <table tableName="表名" domainObjectName="实体类类名" enableCountByExample="false" enableUpdateByExample="false"
               enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false">
        </table>
    </context>
</generatorConfiguration>

4、运行

然后就可以生成实体、mapper、xml,就可以复制到自己的项目中使用了
