逆向生成MySQL对应的pojo和mybatis通过单独的一个工程不影响现有的业务逻辑。
mybatis-generatorConfig工程
通过源码里面的sql生成对应的表结构和表数据。
mybatis-generatorConfig的pom文件
4.0.0 com.idig8 0.0.1-SNAPSHOT mybatis-generatorConfig UTF-8 org.springframework.boot spring-boot-starter-log4j 1.3.8.RELEASE com.alibaba druid 1.1.0 com.alibaba druid-spring-boot-starter 1.1.0 mysql mysql-connector-java 5.1.41 org.mybatis.spring.boot mybatis-spring-boot-starter 1.3.1 tk.mybatis mapper-spring-boot-starter 1.2.4 com.github.pagehelper pagehelper-spring-boot-starter 1.2.3 org.mybatis.generator mybatis-generator-core 1.3.2 compile true
添加generatorConfig.xml文件
GeneratorDisplay.java类
package com.idig8.mybatis.utils; import java.io.File; import java.util.ArrayList; import java.util.List; import org.mybatis.generator.api.MyBatisGenerator; import org.mybatis.generator.config.Configuration; import org.mybatis.generator.config.xml.ConfigurationParser; import org.mybatis.generator.internal.DefaultShellCallback; public class GeneratorDisplay { public void generator() throws Exception{ Listwarnings = new ArrayList (); boolean overwrite = true; //指定 逆向工程配置文件 File configFile = new File("generatorConfig.xml"); ConfigurationParser cp = new ConfigurationParser(warnings); Configuration config = cp.parseConfiguration(configFile); DefaultShellCallback callback = new DefaultShellCallback(overwrite); MyBatisGenerator myBatisGenerator = new MyBatisGenerator(config, callback, warnings); myBatisGenerator.generate(null); } public static void main(String[] args) throws Exception { try { GeneratorDisplay generatorSqlmap = new GeneratorDisplay(); generatorSqlmap.generator(); } catch (Exception e) { e.printStackTrace(); } } }
添加MyMapper.java文件

运行GeneratorDisplay的main方法
复制com.idig8.mapper目录到wx-springboot-mapper项目下
复制com.idig8.pojo 目录到wx-springboot-pojo项目下
复制com.idig8.utils 目录到wx-springboot-common项目下
复制resources mapper到wx-springboot-api的resources里面
PS:mybatis-generatorConfig 可以看成一个单独的项目,主要的目的就是为了升成对应的mapper.xml和对应的pojo实体类,mapper对应的实体。
