springboot添加addEmp.jsp页面
1、控制器：
@Controller @RequestMapping("emp") public class EmpController { @Autowired private EmpService empService; @PostMapping("save") public String save(Emp emp){ empService.save(emp); return "redirect:/emp/findAll"; }
2、业务层
public interface EmpService { List<Emp> findAll(); void save(Emp emp); }
@Transactional @Service public class EmpServiceImpl implements EmpService { @Autowired private EmpDAO empDAO; @Override public void save(Emp emp) { emp.setId(UUID.randomUUID().toString()); empDAO.save(emp); } @Override public List<Emp> findAll() { return empDAO.findAll(); } }
3、dao层
@Repository public interface EmpDAO { public List<Emp> findAll() ; // void save(Emp emp); }
4、.xml
<?xml version="1.0" encoding="utf-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
<mapper namespace="com.chinaunicom.ems.dao.EmpDAO">
<select id="findAll" resultType="Emp">
select * from t_emp
</select>
<insert id="save" parameterType="Emp">
insert into t_emp values (#{id},#{name},#{salary},#{age})
</insert>
</mapper>
