如何实现Springboot版mybatis逆向生成

这篇文章主要介绍如何实现Springboot版mybatis逆向生成，文中介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们一定要看完！

代码生成器

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{        List warnings = 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

1. 复制com.idig8.mapper目录到wx-springboot-mapper项目下
   
   

   
   

2. 复制com.idig8.pojo 目录到wx-springboot-pojo项目下
   
   

   
   

3. 复制com.idig8.utils 目录到wx-springboot-common项目下
   
   

4. 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。
