发送POST请求后，我收到了400错误。
curl localhost:8888/bills/addbill -H "Content-Type: application/json" -X POST -d '{"number":"111A111", "customer":"Customer Cuustomer Rrrr", "phone":"1 800 5551212", "manager":"Manager Manager Manager", "date":"2012-09-17", "curId":{"id":"1"}, "payments":{["id":"1"]}}'
响应如下：
{"timestamp":1503684882518,"status":400,"error":"Bad Request","exception":"org.springframework.http.converter.HttpMessageNotReadableException","message":"Bad Request","path":"/bills/addbill"}
当我尝试反序列化我的JSON数据时，出现了异常。如何正确地反序列化JSON？
账单实体文件如下：

BillView文件是什么？
package ru.test.practice.view;
import io.swagger.annotations.ApiModelProperty;

import java.util.Date;
import java.util.List;
public class BillView {
@ApiModelProperty(hidden = true)
public Integer id;
public String customer;
public String phone;
public String manager;
public String number;
public Date date;
public Currency curId;
public List<PaymentView> payments;
//для jackson
public BillView() {
}
public BillView(Integer id, String number, String customer, String phone, String manager, Date date, Currency curId, List<PaymentView> payments) {
this.id = id;
this.number = number;
this.customer = customer;
this.phone = phone;
this.manager = manager;
this.date = date;
this.curId = curId;
this.payments = payments;
}
@Override
public String toString() {
return "{id:" + id +
"billNumber:" + number +
";customer:" + customer +
";phone:" + phone +
";manager:" + manager +
";date:" + date +
";currencyId:" + curId +
";payments:" + payments +
"}";
}
}
在BillController类中处理POST请求的控制器。
@Override
@ApiOperation(value = "addBill", nickname = "addBill", httpMethod = "POST")
@ApiResponses(value = {
@ApiResponse(code = 200, message = "Success", response = String.class),
@ApiResponse(code = 404, message = "Not Found"),
@ApiResponse(code = 500, message = "Failure")})
@RequestMapping(value = "/addbill", method = {POST})
public void bill(@RequestBody BillView bill) {
billService.add(bill);
}
@Override
@ApiOperation(value = "getBills", nickname = "getBills", httpMethod = "GET")
@RequestMapping(value = "/list", method = {GET})
public List<BillView> bills() {
return billService.bills();
}
最后是我的支付实体类:
import com.fasterxml.jackson.annotation.JsonIgnoreProperties;
import javax.persistence.*;
import java.util.ArrayList;
import java.util.List;
@JsonIgnoreProperties({"hibernateLazyInitializer", "handler"})
@Entity
@Table(name = "Payments")
public class Payment {
@Id
@GeneratedValue
@Column(name = "id")
private Integer id;
@Version
private Integer version;
@Column(name = "name", nullable = false, length = 256)
private String name;
@Column(name = "price", nullable = false)
private float price;
@ManyToMany(targetEntity = ru.bellintegrator.practice.model.Bill.class, mappedBy = "curId")
private List<Bill> bills = new ArrayList<>();
public List<Bill> getBills() {
return bills;
}
public void setBills(List<Bill> bills) {
this.bills = bills;
}
public Integer getId() {
return id;
}
public int getVersion() {
return version;
}
public void setVersion(int version) {
this.version = version;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public float getPrice() {
return price;
}
public void setPrice(float price) {
this.price = price;
}
}
