1.建立Maven工程
2.建立appliaction.properties
加入mybatis-config.xml配置及掃描mapper.xml文件夾配置
3.把mybatis工程中寫好的mappe接口，mapper的xml文件，mybatis-config.xml以及實體類拷貝過來
4.Pom文件修改
1）log4j的依賴只留Log4j其餘兩個刪除
2）加入sprongBoot以及mybatis-Springboot依賴包
３）mybatis-java驅動確認
2）要加上紅框的内容
不然啓動時會出現Unsatisfied dependency expressed through bean property 'sqlSessionFactory'錯誤
5.編寫啓動類
---------------------------------------------------------------
package mybatis.simple;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
@MapperScan(basePackages = {"mybatis.simple.mapperInterface"})
public class MybatisSpringbootApp {
public static void main(String[] args) {
SpringApplication.run(MybatisSpringbootApp.class, args);
}
}
---------------------------------------------------------------
6.編寫Controler
----------------------------------------------------------------
package mybatis.simple.controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;
import mybatis.simple.mapper.UserMapper;
import mybatis.simple.model.SysUser;
import java.util.List;
import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;
@RestController
@RequestMapping("/")
public class UserController {
@Resource
private UserMapper userMapper;
@GetMapping("getOne")
public SysUser selectByUserId(@RequestParam(value = "id") Long id){
return userMapper.selectById(id);
}
@GetMapping("getAll")
public List<SysUser> selectByUserId(){
return userMapper.selectAll();
}
@RequestMapping(value = "/deleteById")
@ResponseBody
public List<SysUser> getBookDetails(HttpServletRequest request) {
String userId = request.getParameter("id");
SysUser sysUser = new SysUser();
sysUser.setId(Long.valueOf(userId));
userMapper.deleteById(sysUser);
return userMapper.selectAll();
}
}
