Spring Boot & H2 - 更新记录



现在让我们更新迄今为止创建的项目,以准备一个完整的更新记录 API 并对其进行测试。

更新控制器

// Use service.saveOrUpdate() to update an employee record
@PutMapping("/employee")
public void updateEmployee(@RequestBody Employee employee) {
   employeeService.saveOrUpdate(employee);
}	

员工控制器

package com.tutorialspoint.controller;

import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.DeleteMapping;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.PutMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import com.tutorialspoint.entity.Employee;
import com.tutorialspoint.service.EmployeeService;

@RestController
@RequestMapping(path = "/emp")
public class EmployeeController {
   @Autowired
   EmployeeService employeeService;

   // Get all employees   
   @GetMapping("/employees")
   public List<Employee> getAllEmployees(){
      return employeeService.getAllEmployees();
   }
   
   // get an employee by id
   @GetMapping("/employee/{id}")
   public Employee getEmployee(@PathVariable("id") int id) {
      return employeeService.getEmployeeById(id);
   }
   
   // delete an employee by id   
   @DeleteMapping("/employee/{id}")
   public void deleteEmployee(@PathVariable("id") int id) {
      employeeService.deleteEmployeeById(id);
   }
   
   // create an employee 
   @PostMapping("/employee")
   public void addEmployee(@RequestBody Employee employee) {
      employeeService.saveOrUpdate(employee);   
   }
   
   // update an employee details
   @PutMapping("/employee")
   public void updateEmployee(@RequestBody Employee employee) {
      employeeService.saveOrUpdate(employee);
   }	
}

运行应用程序

在 Eclipse 中,运行在 应用程序设置 期间准备的“员工应用程序”配置。

Eclipse 控制台将显示类似的输出。

服务器启动并运行后,使用 Postman 发出 POST 请求 -

在 POSTMAN 中设置以下参数。

  • HTTP 方法 - POST

  • URL - https://127.0.0.1:8080/emp/employee

  • 主体 - 一个员工 JSON

{  
   "id": "1",  
   "age": "35",  
   "name": "Julie",  
   "email": "[email protected]"  
}   

点击发送按钮并检查响应状态是否为 OK。

{  
   "id": "1",  
   "age": "35",  
   "name": "Julie",  
   "email": "[email protected]"  
}
