1 明明是get请求报错为post请求 （这个问题已经坑了我两次了）

package com.dianrong.rbms.common.client.matrix;import com.dianrong.rbms.common.client.matrix.result.ReportResult;import feign.Headers;import feign.Param;import feign.RequestLine;/** * @author: wangjun * @create: 2018-06-29  **/public interface MatrixClient {  @Headers({"Content-Type: application/json", "Accept: application/json"})  @RequestLine("GET /api/v3/phone/getReport?ssn={ssn}&phone={phone}")  ReportResult getReport(@Param("ssn") String ssn, @Param("phone") String phone);}

报错 :

Exception in thread "main" feign.FeignException: status 405 reading Mongo#findSingleArchiveByDeviceId2(String,String,String); content:{"timestamp":1488507926013,"status":405,"error":"Method Not Allowed","exception":"org.springframework.web.HttpRequestMethodNotSupportedException","message":"Request method 'POST' not supported","path":"/api/v3/phone/getReport"}    at feign.FeignException.errorStatus(FeignException.java:62)    at feign.codec.ErrorDecoder$Default.decode(ErrorDecoder.java:91)    at feign.SynchronousMethodHandler.executeAndDecode(SynchronousMethodHandler.java:134)    at feign.SynchronousMethodHandler.invoke(SynchronousMethodHandler.java:76)    at feign.ReflectiveFeign$FeignInvocationHandler.invoke(ReflectiveFeign.java:103)    at com.sun.proxy.$Proxy4.findSingleArchiveByDeviceId2(Unknown Source)    at com.chinamobile.iot.App.main(App.java:18)    at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)    at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62)    at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43)    at java.lang.reflect.Method.invoke(Method.java:497)    at com.intellij.rt.execution.application.AppMain.main(AppMain.java:144)

提示"Request method 'POST' not supported" 找GET是否配置错误，找不到原因 最后结果是 @Herders里边的键值对冒号后面必须有个空格 @Headers("key: {value}")

另外，如果GET方法有一堆参数： 想要设置一个request实体类，把所有参数都包进去，放到HTTP 的body来上传，也会被当成POST。一句话：GET参数不支持复杂对象（只支持String、Integer这些简单对象）
