SpringBoot JdbcTemplate

引入需要的pom文件节点

<dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-jdbc</artifactId>
</dependency>

(1. )创建GradeDao类

package com.qzy.dao;

import com.qzy.entity.Grade;

import java.util.List;

public interface IGradeDao {
    public int insertGrade(Grade grade);

    public  int updateGrade(Grade grade);

    public  int deleteGrade(Integer id);

    public List<Grade> findAll();
}

(2. )创建IGradeService类

package com.qzy.service.impl;

import com.qzy.dao.IGradeDao;
import com.qzy.entity.Grade;
import com.qzy.service.IGradeService;
import org.springframework.stereotype.Service;

import javax.annotation.Resource;
import java.util.List;

@Service("iGradeService")
public class IGradeServiceImpl implements IGradeService {
    @Resource
    private IGradeDao iGradeDao;


    @Override
    public int insertGrade(Grade grade) {
        return iGradeDao.insertGrade(grade);
    }

    @Override
    public int updateGrade(Grade grade) {
        return iGradeDao.updateGrade(grade);
    }

    @Override
    public int deleteGrade(Integer id) {
        return iGradeDao.deleteGrade(id);
    }

    @Override
    public List<Grade> findAll() {
        return iGradeDao.findAll();
    }
}

(3. )创建JDBCTemplateController类

package com.qzy.controller;

import com.qzy.entity.Grade;
import com.qzy.service.IGradeService;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import javax.annotation.Resource;
import java.util.List;

@RestController
public class JDBCTemplateController {
    @Resource
    private IGradeService iGradeService;


    @RequestMapping("/insertGrade")
    public int insertGrade(){
        return iGradeService.insertGrade(new Grade("S10"));
    }
    @RequestMapping("/updateGrade")
    public int updateGrade(){
        return  iGradeService.updateGrade(new Grade(10012,"S1"));
    }
    @RequestMapping("/deleteGrade")
    public int deleteGrade(){
        return iGradeService.deleteGrade(8);
    }
    @RequestMapping("/findAll")
    public List<Grade> findAll(){
        return iGradeService.findAll();
    }
}
