@RequestBody没有在春季启动工作

Question

您好我是新来的春天开机，已经发布采购信息问题

我收到以下错误

 2019-01-31 10:41:56.011  WARN 9532 --- [nio-8090-exec-1] .w.s.m.s.DefaultHandlerExceptionResolver : Resolved [org.springframework.http.converter.HttpMessageNotReadableException: I/O error while reading input message; nested exception is java.net.SocketTimeoutException]

我使用的邮差用于测试目的

我有下面的代码片段

控制器：

@RestController
public class EmployeeController {

    @Autowired
    private EmployeeService employeeService;

    public EmployeeController() {}
    public EmployeeController(EmployeeService employeeService) {
        this.employeeService = employeeService;
    }

    @GetMapping("/employee")
    public List<Employee> getAllEmployee() {
        System.out.println("EmployeeController.getAllEmployee()");
        return this.employeeService.getAllEmployee();
    }

    @PostMapping(value="/employee")
    public Employee addEmployee( @RequestBody Employee employee ) {
        System.out.println("EmployeeController.addEmployee()");
        System.out.println(employee.toString());
//      this.employeeService.addEmployee( employee );
        return employee;
    }
}

实体类为：

@Entity
@Table(name="emp_table")
public class Employee  {

    private static final long serialVersionUID = 1L;
    @Id
    private Long id; 
    private String firstName;
    private String lastName;
    private String city;
    private Double salary;

    public Employee() {}
    public Employee(Long id, String firstName, String lastName, String city, Double salary) {
        this.id = id;
        this.firstName = firstName;
        this.lastName = lastName;
        this.city = city;
        this.salary = salary;
    }
    // Getters and Setters + toString()
}

邮差POST请求

从邮差响应堆栈跟踪

改变从邮差API测试工具高级REST客户端，然后将其worked.Don't知道为什么吗？ 任何一个可以解释......？
