MyBatis自动生成Dao层,从数据库的表映射到Java的数据层。包括 Mapper接口的定义,Mapper文件中的sql脚本以及接口中用到的对象

新建Maven项目(我的是基于SpringBoot)

根据需求更改数据库配置信息,驱动包信息,目录数据 以及表信息即可
<?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> <!--JDBC驱动jar包的位置--> <classPathEntry location="D:/app/maven/repository/mysql/mysql-connector-java/8.0.17/mysql-connector-java-8.0.17.jar"/> <context id="default" targetRuntime="MyBatis3"> <!--创建Java类时是否取消生成注释--> <commentGenerator> <property name="suppressDate" value="true"/> <property name="suppressAllComments" value="true"/> </commentGenerator> <!--JDBC数据库连接--> <jdbcConnection driverClass="com.mysql.cj.jdbc.Driver" connectionURL="jdbc:mysql://10.22.33.86:4000/test1?characterEncoding=utf8" userId="root" password="111"> </jdbcConnection> <!-- Model模型生成器,用来生成含有主键key的类,记录类 以及查询Example类 targetPackage 指定生成的model生成所在的包名 targetProject 指定在该项目下所在的路径 --> <javaModelGenerator targetPackage="com.imodule.product.generated.pojo" targetProject="./src/main/java"> <!-- 是否允许子包,即targetPackage.schemaName.tableName --> <property name="enableSubPackages" value="false"/> <!-- 是否对model添加构造函数 --> <property name="constructorBased" value="true"/> <!-- 是否对类CHAR类型的列的数据进行trim操作 --> <property name="trimStrings" value="true"/> <!-- 建立的Model对象是否 不可改变 即生成的Model对象不会有 setter方法,只有构造方法 --> <property name="immutable" value="false"/> </javaModelGenerator> <!-- mapper映射文件生成所在的目录 为每一个数据库的表生成对应的SqlMap文件 --> <sqlMapGenerator targetPackage="generator" targetProject="./src/main/resources"> <property name="enableSubPackages" value="false"/> </sqlMapGenerator> <!-- 客户端代码,生成易于使用的针对Model对象和XML配置文件的代码 type="ANNOTATEDMAPPER",生成Java Model和基于注解的Mapper对象 type="MIXEDMAPPER",生成基于注解的Java Model和相应的Mapper对象 type="XMLMAPPER",生成SQLMap XML文件和独立的Mapper接口 --> <javaClientGenerator type="XMLMAPPER" targetPackage="com.imodule.product.generated.mapper" targetProject="./src/main/java"> <property name="enableSubPackages" value="false"/> </javaClientGenerator> <!--tables--> <table tableName="PRD_BASE" domainObjectName="PrdBase" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"> </table> <table tableName="prd_property" domainObjectName="PrdProperty" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"> </table> </context> </generatorConfiguration>
IDEA- 点击Maven - Plugins - 选中 Mybatis-generator 双击即可
[WARNING] Table configuration with catalog null, schema null, and table XXX did not resolve to any tables
请注意表明的大小写是否与数据库一致 ,我将表名改为大写就都欧克啦!!!
到这里就欧克啦,后期要使用的时候 maven 打包一下即可啦,然后在别的项目直接引用即可!
这里有个不好的点是所有的表要一一配置,我再康康有没有啥更快捷的办法,能对整个数据库自动生成的哈哈哈哈 找到了我再来更新~
