Use SpringBoot to process JSON data (2)

Create an entity class and encapsulate the Employee class

@Data Role: get getter() and setter() method
@AllArgsConstructor role: construct full parameter method
@NoArgsConstructor role: construct empty parameter method

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

@Data
@AllArgsConstructor
@NoArgsConstructor
public class Employee {
    private String name;
    private String department;
    private String number;
    private Integer salary;
}

Create the EmployeeController class

import com.example.helloworld.pojo.Employee;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RestController;
import java.util.Arrays;
import java.util.List;

@RestController
public class EmployeeController {

    //获取单个对象信息
    @GetMapping("/findOneEmployee")
    public Employee getEmployee(){
        return new Employee("张三","销售部","A3333",9000);
    }

    //获取多个对象信息
    @GetMapping("/findMultiEmployee")
    public List<Employee> getEmployees(){
        return Arrays.asList(
                new Employee("张三","销售部","A3333",9000),
                new Employee("黄三","技术部","B3333",19000),
                new Employee("李三","财务部","C3333",10000),
                new Employee("王三","销售部","A2222",9000)
        );
    }

    //新增一个对象
    @PostMapping("/addOneEmployee")
    public String addEmployee(@RequestBody Employee employee){
        System.out.println("添加："+ employee); //后台返回添加员工信息
        return "成功添加一个对象！";//前端返回添加成功信息
    }

    //新增多个对象
    @PostMapping("/addMultiEmployee")
    public String addEmployees(@RequestBody List<Employee> employees){
        employees.forEach(employee -> {System.out.println("添加："+employee);});
        return "成功添加多个对象！";
    }
}
