    使用JavaAPI实现数据库基本操作

    Controller

    package cn.techny.demo.Controller;
    
    import cn.techny.demo.Service.DemoService;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.web.bind.annotation.GetMapping;
    import org.springframework.web.bind.annotation.RestController;
    
    @RestController
    public class DemoController {
    
        public DemoService demoService;
    
        @Autowired
        public DemoController(DemoService demoService){
            this.demoService = demoService;
        }
        @GetMapping(path = "/demo")
        public int demo(){
            return demoService.DemoInsert();
        }
    }

    Service

    package cn.techny.demo.Service;
    
    import cn.techny.demo.dao.StuInfoDao;
    import cn.techny.demo.entity.StuInfoEntity;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.stereotype.Service;
    
    import java.util.Date;
    
    @Service
    public class DemoService {
    
        private final StuInfoDao stuInfoDao;
    
        @Autowired
        public DemoService(StuInfoDao stuInfoDao) {
            this.stuInfoDao = stuInfoDao;
        }
    
        public int DemoInsert() {
            StuInfoDao stuInfoDao = this.stuInfoDao;
            int res = 1;
            Date date = new Date();
            StuInfoEntity stuInfoEntity = new StuInfoEntity(
                    "test", "test", "1", (short) 1, "test", "test", "test", date, "test");
            res = stuInfoDao.insert(stuInfoEntity);
            return res;
        }
    }

    封装sql语句到mapper中,直接调用执行即可
