尝试使用Spring启动MVC在post方法中传递List，我试图将一个json数组传递给一个带有List的rest api，但是它说Request主体格式不正确。
这是我传递的JSON格式
[{"quotation":100001,"customer":"ZOMRAN KHALED MEDICAL UNIT",
"currency":"Algerian dinar (DZD)","country":"Algeria","language":"English",
"product":"9100C","modality":"LCS","subModality":"ARC","services":"PM,CM",
"serviceType":"SWIFT","price":"1500","responseTime":"24H","createdTime":"24/04/2018"},
{"quotation":100002,"customer":"ZOMRAN KHALED MEDICAL UNIT",
"currency":"Algerian dinar (DZD)","country":"Algeria","language":"English",
"product":"9100C","modality":"LCS","subModality":"ARC","services":"PM,CM",
"serviceType":"SWIFT","price":"1500","responseTime":"24H","createdTime":"24/04/2018"}
]
这是我的Java控制器，我正在捕捉数组。
@RequestMapping(value = "/carePlanQuotationHistory", method = RequestMethod.POST, produces = {
MediaType.APPLICATION_JSON_VALUE, MediaType.TEXT_PLAIN_VALUE })
public @ResponseBody Response CarePlanQuotationHistory1(@RequestBody List<CarePlanHistoryRequest> carePlanQuotationHistory1) throws Exception {
int a;
try {
a = productService.CarePlanQuotationHistory1(carePlanQuotationHistory1);
} catch (Exception ex) {
return new Response("400", ex.getMessage());
}
return new Response("200", a);
}
这是我的pojo
package com.careplan.springbootstarter.request;
public class CarePlanHistoryRequest {
private String quotation;
private String customer;
private String currency;
private String country;
private String language;
private String product;
private String modality;
private String subModality;
private String services;
private String serviceType;
private String price;
private String responseTime;
private String createdTime;
public CarePlanHistoryRequest() {
super();
// TODO Auto-generated constructor stub
}
public CarePlanHistoryRequest(String quotation, String customer, String currency, String country, String language,
String product, String modality, String subModality, String services, String serviceType, String price,
String responseTime, String createdTime) {
super();
this.quotation = quotation;
this.customer = customer;
this.currency = currency;
this.country = country;
this.language = language;
this.product = product;
this.modality = modality;
this.subModality = subModality;
this.services = services;
this.serviceType = serviceType;
this.price = price;
this.responseTime = responseTime;
this.createdTime = createdTime;
}
public String getQuotation() {
return quotation;
}
public void setQuotation(String quotation) {
this.quotation = quotation;
}
public String getCustomer() {
return customer;
}
public void setCustomer(String customer) {
this.customer = customer;
}
public String getCurrency() {
return currency;
}
public void setCurrency(String currency) {
this.currency = currency;
}
public String getCountry() {
return country;
}
public void setCountry(String country) {
this.country = country;
}
public String getLanguage() {
return language;
}
public void setLanguage(String language) {
this.language = language;
}
public String getProduct() {
return product;
}
public void setProduct(String product) {
this.product = product;
}
public String getModality() {
return modality;
}
public void setModality(String modality) {
this.modality = modality;
}
public String getSubModality() {
return subModality;
}
public void setSubModality(String subModality) {
this.subModality = subModality;
}
public String getServices() {
return services;
}
public void setServices(String services) {
this.services = services;
}
public String getServiceType() {
return serviceType;
}
public void setServiceType(String serviceType) {
this.serviceType = serviceType;
}
public String getPrice() {
return price;
}
public void setPrice(String price) {
this.price = price;
}
public String getResponseTime() {
return responseTime;
}
public void setResponseTime(String responseTime) {
this.responseTime = responseTime;
}
public String getCreatedTime() {
return createdTime;
}
public void setCreatedTime(String createdTime) {
this.createdTime = createdTime;
}
}
这是我们遇到的错误

看起来您传入的JSON格式不正确。您已将引用定义为String，但将其作为数值传递。我建议将引用更改为Integer，或者在将其作为JSON传递时将其值包装在引号中。
