spring - 如何在Spring Boot API中通过requestbody获取对象列表

Question

通过 Controller 中的@RequestBody获取对象列表并处理list中的每个对象以进行业务逻辑。

我已经尝试过了，但是没有用

@RequestMapping(value="/updateservicetype", method=RequestMethod.POST,produces="application/json")
    public @ResponseBody ServiceTypesMessage updateServiceType(@RequestBody List<BarberServiceType> serviceTypes,final HttpServletResponse response){

还尝试了以下方法:

@RequestMapping(value="/updateservicetype", method=RequestMethod.POST,produces="application/json")
    public @ResponseBody ServiceTypesMessage updateServiceType(@RequestBody BarberServiceType[] serviceTypes,final HttpServletResponse response){

Answer 1

下面对我有用

@RequestMapping(value = "/payments", method = RequestMethod.POST, consumes = MediaType.APPLICATION_JSON_VALUE, produces = MediaType.APPLICATION_JSON_VALUE)
public @ResponseBody List<Payment> batchCreate(@RequestBody List<Payment> payments) {
  return paymentService.create(payments);
}

您需要在类(class)路径中使用 jackson

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>2.6.0</version>
</dependency>

杰森(Json)是

[{"sort":"10-20-30","account":"1234"},{"sort":"10-20-30","account":"1234"}]
