This article mainly introduces how to achieve Springboot version of mybatis reverse generation, the article is very detailed, has a certain reference value, interested friends must read it!

Code generator

Reverse generation of pojo and mybatis corresponding to mysql does not affect existing business logic through a separate project.

Mybatis-generatorConfig project

Generate the corresponding table structure and table data through the sql in the source code.

Pom file for mybatis-generatorConfig

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

Add a generatorConfig.xml file

GeneratorDisplay.java class

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 {List warnings = new ArrayList (); boolean overwrite = true / / specify reverse engineering configuration files 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 ();}

Add a MyMapper.java file

Run the main method of GeneratorDisplay

Copy the com.idig8.mapper directory to the wx-springboot-mapper project

Copy the com.idig8.pojo directory to the wx-springboot-pojo project

Copy the com.idig8.utils directory to the wx-springboot-common project

Copy resources mapper into the resources of wx-springboot-api

PS:mybatis-generatorConfig can be seen as a separate project, the main purpose is to upgrade to the corresponding mapper.xml and the corresponding pojo entity class, mapper corresponding entity.
