整合MybatisPlus心得

整合MybatisPlus心得

关于我在整合MybatisPlus中，遇到的bug、错误提示

1. 逻辑删除的时候，在数据库中创建删除字段时千万不要使用delete关键字

2. MybatisPlust3.2以上自带逻辑删除插件，所有可不用写这个代码

   //逻辑删除插件
   @Bean
   public ISqlInjector sqlInjector(){
       return new LogicSqlInjector();
   }
   

   mybatis-plus:
       #设置逻辑删除的值：1-已删除；0-没有删除
       #可自行设置值，但是一般不设置，1和0为默认值
     global-config:
       db-config:
         logic-delete-value: 1
         logic-not-delete-value: 0
   

3. 测试时，控制台会报各种样儿的错误，原因是版本不配置（兼容）。下边是整合MybatisPlus的pom.xml文件
