application.properties中添加配置

PersonDTO
package com.example.demo1019.dto;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;@Table(name = "person")
@Entity
public class PersonDTO {
@Id
@GeneratedValue
// 这里的id必须为int类型,采用自增长的顺序往数据库添加,并且注意引用正确的包,否则会报错
private int id;@Column(name = "name", nullable = true, length = 20)
private String name;@Column(name = "age", nullable = true, length = 4)

return name;
}public void setName(String name) {

}}
PersonRepository
package com.example.demo1019.dao;
import org.springframework.data.jpa.repository.JpaRepository;
import com.example.demo1019.dto.PersonDTO;
public interface PersonRepository extends JpaRepository<PersonDTO, Long> {
}
新建PersonService
package com.example.demo1019.service;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;import com.example.demo1019.dao.PersonRepository;
import com.example.demo1019.dto.PersonDTO;@Service
public class PersonService {
@Autowired
private PersonRepository personRepository;public List<PersonDTO> findAll() {
return (List<PersonDTO>) personRepository.findAll();
}public void save(PersonDTO personDTO) {
personDTO = new PersonDTO();
personDTO.setAge(26);
personDTO.setName("啾啾");
personRepository.save(personDTO);
}public void deletePerson(Long id) {
personRepository.deleteById(id);
}
}
PersonController
package com.example.demo1019.controller;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;import com.example.demo1019.dto.PersonDTO;
import com.example.demo1019.service.PersonService;@Controller
public class PersonController {
@Autowired
private PersonService personService;@RequestMapping("/getPersonList")
@ResponseBody
public List<PersonDTO> getPersonList() {
return personService.findAll();
}@RequestMapping("/addPerson")
@ResponseBody
public String addPerson(PersonDTO personDTO) {
personService.save(personDTO);
return "添加成功";
}@RequestMapping("/deletePerson/{id}")
@ResponseBody
public String deletePerson(@PathVariable("id") Long id) {
personService.deletePerson(id);
return "删除成功";
}
}
整体路径如下:
