1.首先在pom文件里面加dependency依赖

             
              
                  
       
        org.mybatis
                   
       
        mybatis-spring
                   
       
        ${mybatis-spring}
               
              
                  
       
        org.mybatis.generator
                   
       
        mybatis-generator-core
                   
       
        1.3.2
               
              
                  
       
        mysql
                   
       
        mysql-connector-java
                   
       
        5.1.8
               
          
     

2.在pom文件里面加入插件依赖

             
                  
                       
        
         org.apache.maven.plugins
                        
        
         maven-source-plugin
                        
        
         2.2.1
                        
                            
                                 
          
           attach-source
                                  
           
           
            jar
            
                                  
           
            
            
             **/org/**
             
            
                              
                         
                    
                   
                       
        
         org.apache.maven.plugins
                        
        
         maven-jar-plugin
                        
        
         2.4
                        
                            
                                 
          
           attach-jar
                                  
           
           
            jar
            
                                  
           
            
            
             true
             
             
            
             org.mybatis.generator.api.ShellRunner
             
            
            
            
             **/org/**
             
            
                              
                         
                    
                   
               
          
     

3.创建generatorConfig.xml

4.创建自动生成逆向工程的类

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;/** * mybatis逆向工程 * Created by fwj on 16-3-18. */public class Generator {    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 {            Generator generatorSqlmap = new Generator();            generatorSqlmap.generator();        } catch (Exception e) {            e.printStackTrace();        }    }}
