IDEA 下 hibernate 反向生成实体和映射文件

IDEA 下 hibernate 反向生成实体和映射文件

选中项目，鼠标右键项目，选择Add Frameworks Support 或者 选中项目+F4

或者 选中项目+F4

现在看resources多了hibernate.cfg.xml

接下来配置hibernate.cfg.xml

  
    
    jdbc:mysql://localhost:3306/disaster_tolerant
    
    com.mysql.jdbc.Driver
    
    root
    
    123456
  

连接你的数据库

在Persistence中右键项目，然后点击Generate Persistence Mapping，选择By Database Schema

勾勾选选的，你懂的

最后生成的pojo文件给  大家 OB一哈

package com.nelsoner.pojo.test;
