mybatis代码生成器

1.pom.xml文件添加依赖

 

<build>
    <finalName>mybatis</finalName>
    <pluginManagement>
            <plugins>
                <plugin>
                    <groupId>org.apache.maven.plugins</groupId>
                    <artifactId>maven-compiler-plugin</artifactId>
                    <configuration>
                        <source>1.7</source>
                        <target>1.7</target>
                    </configuration>
                    <version>3.3</version>
                </plugin>
                <plugin>
                    <groupId>org.mybatis.generator</groupId>
                    <artifactId>mybatis-generator-maven-plugin</artifactId>
                    <version>1.3.2</version>
                    <dependencies>
                        <dependency>
                            <groupId>mysql</groupId>
                            <artifactId>mysql-connector-java</artifactId>
                            <version>5.1.35</version>
                        </dependency>
                    </dependencies>
                    <configuration>
                         <!--配置文件的路径-->
                         <configurationFile>${basedir}/src/main/resources/generatorConfig.xml</configurationFile> 
                        <overwrite>true</overwrite>
                    </configuration>
                </plugin>
            </plugins>
        </pluginManagement>
  </build>

 

注意generatorConfig文件的路径！

2.在resources下新建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="test" targetRuntime="MyBatis3">
    
        <!-- 是否去除自动生成的注释 true：是 ： false:否 -->
        <commentGenerator>
            <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/mybatis" 
　　　　　　　　　　userId="root" password="root">
        </jdbcConnection>
        
        <!-- 生成模型的包名和位置 -->
        <javaModelGenerator targetPackage="com.mybatis.springmvc.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 .xml -->
        <sqlMapGenerator targetPackage="com.mybatis.springmvc.dao.mapping" targetProject="src/main/java">
            <property name="enableSubPackages" value="true" />
        </sqlMapGenerator>

        <!-- 生成DAO的包名和位置 -->
        <javaClientGenerator type="XMLMAPPER"
            targetPackage="com.mybatis.springmvc.dao" implementationPackage="com.mybatis.springmvc.dao"  targetProject="src/main/java">
            <property name="enableSubPackages" value="true" />
        </javaClientGenerator>
        
        <!--对应数据库表名 -->
        <table tableName="sys_user" domainObjectName="SysUser"
            enableCountByExample="false" enableUpdateByExample="false"
            enableDeleteByExample="false" enableSelectByExample="false"
            selectByExampleQueryId="false">
        </table>
    </context>
</generatorConfiguration>

3.选中项目右键Run AS ----->Run Configurations ---->Maven Build 新建 mybatis-generator:generate命令

运行成功后在项目中可以看到
