                .execute();
    }

}

2.3 主启动类一定要配置mapper的路径

配置到mapper文件所在的文件夹路径

package com.example.demo;

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
@MapperScan("com.example.demo.system.mapper")
public class DemoApplication {
    
    

    public static void main(String[] args) {
    
    
        SpringApplication.run(DemoApplication.class, args);
    }

}

2.4 测试文件

package com.example.demo;




import com.example.demo.system.po.UserEntity;
import com.example.demo.system.service.UserService;
import org.junit.jupiter.api.Test;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import java.util.List;

@SpringBootTest
class DemoApplicationTests {
    
    

    @Test
    void contextLoads() {
    
    
    }

    @SpringBootTest
    public static class SampleTest {
    
    

        @Autowired
        private UserService userService;

        @Test
        public void testSelect() {
    
    
            System.out.println(("----- selectAll method test ------"));
            List<UserEntity> userList = userService.list();
            for(UserEntity user:userList){
    
    
                System.out.println(user.toString());
            }

        }

    }
}

2.6 自动填充配置

2.6.1 自动填充配置

 //自动填充
        TableFill gmtCreate = new TableFill("gmt_create", FieldFill.INSERT);
        TableFill gmtModified = new TableFill("gmt_modified", FieldFill.INSERT_UPDATE);

2.6.2 基础类配置

 //设置BaseEntity
        strategy.setSuperEntityClass("com.atguigu.guli.service.base.model.BaseEntity");
        // 填写BaseEntity中的公共字段
        strategy.setSuperEntityColumns("id", "gmt_create", "gmt_modified");

2.6.3 逻辑字段配置

strategy.setLogicDeleteFieldName("is_deleted");//逻辑删除字段名
        strategy.setEntityBooleanColumnRemoveIsPrefix(true);//去掉布尔值的is_前缀
