1、Role类:
package com.wbg.springbootdemo.entity; import javax.persistence.Entity; import javax.persistence.Id; import javax.persistence.Table; @Entity @Table public class Role { @Override public String toString() { return "Role{" + "id=" + id + ", roleName=‘" + roleName + ‘\‘‘ + ", note=‘" + note + ‘\‘‘ + ‘}‘; } @Id int id; String roleName; String note; public Role() { } public int getId() { return id; } public Role(int id) { this.id = id; } public void setId(int id) { this.id = id; } public String getRoleName() { return roleName; } public void setRoleName(String roleName) { this.roleName = roleName; } public String getNote() { return note; } public void setNote(String note) { this.note = note; } public Role(int id, String roleName, String note) { this.id = id; this.roleName = roleName; this.note = note; } }
2、 RoleMapper接口继承JpaRepository
package com.wbg.springbootdemo.dao; import com.wbg.springbootdemo.entity.Role; import org.springframework.data.jpa.repository.JpaRepository; import org.springframework.stereotype.Repository; @Repository public interface RoleMapper extends JpaRepository<Role,Integer> { }
3、RoleService
package com.wbg.springbootdemo.service; import com.wbg.springbootdemo.entity.Role; import java.util.List; import java.util.Optional; public interface RoleService { List<Role> listAll(); void save(Role role); void update(Role role); void delete(int id); Optional<Role> findById(int id); }
4、RoleServiceImpl实现类
package com.wbg.springbootdemo.service.impl; import com.wbg.springbootdemo.dao.RoleMapper; import com.wbg.springbootdemo.entity.Role; import com.wbg.springbootdemo.service.RoleService; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; import java.util.List; import java.util.Optional; @Service public class RoleServiceImpl implements RoleService { @Autowired private RoleMapper roleMapper; /** * * 查询全部 * @return */ @Override public List<Role> listAll() { return roleMapper.findAll(); } /** * 添加 * @param role */ @Override public void save(Role role) { roleMapper.save(role); System.out.println("添加"); } //如果有就修改、没有就添加 @Override public void update(Role role) { roleMapper.saveAndFlush(role); } /** * 删除 * @param id */ @Override public void delete(int id) { roleMapper.delete(new Role(id)); } /** * 查询 * @param id * @return */ @Override public Optional<Role> findById(int id) { return roleMapper.findById(id); } }
5、RoleController
package com.wbg.springbootdemo.controller; import com.wbg.springbootdemo.entity.Role; import com.wbg.springbootdemo.service.RoleService; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.web.bind.annotation.*; import java.util.List; import java.util.Optional; @RestController @RequestMapping("/role") public class RoleController { @Autowired private RoleService roleService; @GetMapping("/all") public List<Role> listAll(){ return roleService.listAll(); } @GetMapping("/delete") public List<Role> delete(int id){ roleService.delete(id); return roleService.listAll(); } @GetMapping("/getById") public Optional<Role> getById(int id){ return roleService.findById(id); } @PostMapping("/insert") public List<Role> insert( Role role){ roleService.save(role); return roleService.listAll(); } @PostMapping("/update") public List<Role> update(Role role){ roleService.update(role); return roleService.listAll(); } }
