Spring Cloud Openfeign使用DTO发起GET

在Openfeign中使用@QueryMap，Spring Cloud Openfeign使用@SpringQueryMap。
如果不加的话，客户端请求时会发起一个POST请求，导致HTTP 405错误。

import org.springframework.cloud.openfeign.SpringQueryMap;

@Operation(description = "根据对象中的值搜索费用")
@GetMapping(value = "/searchCharge")
List<Charge> searchCharge(@SpringQueryMap Charge searchParam);
