0.在Intellij IDEA创建maven项目

1. 在maven项目的pom.xml 添加mybatis-generator-maven-plugin 插件

         
      
       xxx
          
            
               
        
         org.mybatis.generator
                
        
         mybatis-generator-maven-plugin
                
        
         1.3.2
                
                  
         
          true
                   
         
          true
                 
              
           
        
     

2. 在maven项目下的src/main/resources 目录下建立名为 generatorConfig.xml的配置文件，作为mybatis-generator-maven-plugin 插件的执行目标，模板如下：

这里使用了外置的配置文件generator.properties，可以将一下属性配置到properties文件之中，增加配置的灵活性：

jdbc.driverLocation=D:\\maven\\com\\oracle\\ojdbc14\\10.2.0.4.0\\ojdbc14-10.2.0.4.0.jar  jdbc.driverClass=oracle.jdbc.driver.OracleDriver  jdbc.connectionURL=jdbc:oracle:thin:@//localhost:1521/XE  jdbc.userId=LOUIS  jdbc.password=123456

项目目录如下：

3. 在Intellij IDEA添加一个“Run运行”选项，使用maven运行mybatis-generator-maven-plugin插件 ：

之后弹出运行配置框，为当前配置配置一个名称，这里其名为"generator",然后在 “Command line” 选项中输入“mybatis-generator:generate  -e”

这里加了“-e ”选项是为了让该插件输出详细信息，这样可以帮助我们定位问题

如果添加成功，则会在run 选项中有“generator” 选项，如下：

点击运行，然后不出意外的话，会在控制台输出：

看到BUILD SUCCESS，则大功告成，如果有错误的话，由于添加了-e 选项，会把具体的详细错误信息打印出来的，根据错误信息修改即可
