mybatis逆向工程 Idea + Eclipse

IDEA

1. maven quickstart构建maven工程，安装插件MyBatis Generator

 

 2. pom依赖引入 ， 直接copy

    <dependency>

      <artifactId>mysql-connector-java</artifactId>

    </dependency>
    <!-- mybatis依赖 -->

          </dependency>
        </dependencies>
      </plugin>
    </plugins>
  </build>
</project>

3. 会引入mybatis插件

4. 配置generatorConfig.xml文件

5. mybatis-generator:generate生成

Eclipse

1. 新建maven项目, 目录结构

 2. 增加pom依赖包

<!-- 添加mybatis依赖 -->
<dependency>
  <groupId>org.mybatis</groupId>
  <artifactId>mybatis</artifactId>
  <version>x.x.x</version>
</dependency>
<!-- 添加mybatis/spring整合包依赖 -->
<dependency>
  <groupId>org.mybatis</groupId>
  <artifactId>mybatis-spring</artifactId>
  <version>x.x.x</version>
</dependency>
<!-- 添加mysql驱动依赖 -->
<dependency>
  <groupId>mysql</groupId>
  <artifactId>mysql-connector-java</artifactId>
  <version>x.x.x</version>
</dependency>
 
<build>
        
            <plugins>
                <!--mybatis逆向工程 -->
                <plugin>
                    <groupId>org.mybatis.generator</groupId>
                    <artifactId>mybatis-generator-maven-plugin</artifactId>
                    <version>x.x.x</version>
                    <configuration>
                        <!-- 如果出现jdbc异常在此处引入jdbc包 -->
                    </configuration>
                </plugin>
            </plugins>
        
</build>

3. src/main/resources中新建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="test" targetRuntime="MyBatis3">
        <plugin type="org.mybatis.generator.plugins.EqualsHashCodePlugin"></plugin>  
        <plugin type="org.mybatis.generator.plugins.SerializablePlugin"></plugin> 
         <plugin type="org.mybatis.generator.plugins.ToStringPlugin"></plugin> 
        <commentGenerator>
            <!-- 这个元素用来去除指定生成的注释中是否包含生成的日期 false:表示保护 -->
            <!-- 如果生成日期，会造成即使修改一个字段，整个实体类所有属性都会发生变化，不利于版本控制，所以设置为true -->
            <property name="suppressDate" value="true" />
            <!-- 是否去除自动生成的注释 true：是 ： false:否 -->
            <property name="suppressAllComments" value="true" />
        </commentGenerator>
        <!--数据库链接URL，用户名、密码 -->
        <jdbcConnection driverClass="com.mysql.jdbc.Driver"
            connectionURL="jdbc:mysql://127.0.0.1:3306/db_second_kill" userId="root" password="root">
            </jdbcConnection>
        <javaTypeResolver>
            <!-- This property is used to specify whether MyBatis Generator should 
                force the use of java.math.BigDecimal for DECIMAL and NUMERIC fields, -->
            <property name="forceBigDecimals" value="false" />
        </javaTypeResolver>
        <!-- 生成模型的包名和位置 -->
        <javaModelGenerator targetPackage="com.jay.kill.entity"
            targetProject="src/main/java">
            <property name="enableSubPackages" value="true" />
            <property name="trimStrings" value="true" />
        </javaModelGenerator>
        <!-- 生成映射文件的包名和位置 -->
        <sqlMapGenerator targetPackage="mapper"
            targetProject="src/main/resources">
            <property name="enableSubPackages" value="true" />
        </sqlMapGenerator>
        <!-- 生成DAO的包名和位置 -->
        <javaClientGenerator type="XMLMAPPER"
            targetPackage="com.jay.kill.dao"  targetProject="src/main/java">
            <property name="enableSubPackages" value="true" />
        </javaClientGenerator>
        
        <!-- 要生成哪些表 -->
        <table tableName="item" domainObjectName="Item"
            enableCountByExample="false" enableUpdateByExample="false"
            enableDeleteByExample="false" enableSelectByExample="false"
            selectByExampleQueryId="false">
        </table>
        <table tableName="item_kill" domainObjectName="ItemKill"
            enableCountByExample="false" enableUpdateByExample="false"
            enableDeleteByExample="false" enableSelectByExample="false"
            selectByExampleQueryId="false">
        </table>
        <table tableName="item_kill_success" domainObjectName="ItemKillSuccess"
            enableCountByExample="false" enableUpdateByExample="false"
            enableDeleteByExample="false" enableSelectByExample="false"
            selectByExampleQueryId="false">
        </table>
        <table tableName="random_code" domainObjectName="RandomCode"
            enableCountByExample="false" enableUpdateByExample="false"
            enableDeleteByExample="false" enableSelectByExample="false"
            selectByExampleQueryId="false">
        </table>
        <table tableName="user" domainObjectName="User"
            enableCountByExample="false" enableUpdateByExample="false"
            enableDeleteByExample="false" enableSelectByExample="false"
            selectByExampleQueryId="false">
        </table>
    </context>
</generatorConfiguration>

3.  配置run Configurations --> 点击Workspace选中当前目录 --> 填写mybatis-generator:generate --> 运行
