现在项目使用得是springcloud,把每个模块得切成一个个服务，用来解耦，如何将他们联系起来呢，就是fegin远程调用，虽然操作比较简单，但是还是遇到了不少坑，所以在这里做下记录。
具体微服务操作常用介绍,以及fegin得简单运用可以见SpringCloud微服务框架搭建
这里主要讲fegin如何传参

1.marven配置

<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-feign</artifactId>
</dependency>

2.在启动类上加入注解

@EnableDiscoveryClient
@EnableFeignClients

3.重点fegin得inter接口

@FeignClient(value = "mgmtServer", name = "mgmtServer")
public interface ParkClientService {
@RequestMapping(value = "/srv/parkinghis/insert",method = RequestMethod.POST)
public SrvResult<?> insert(@RequestBody Map<String,Object> map);
}
重点是上面得@RequestBody

controller中如何进行调用呢

@ResponseBody
@RequestMapping(value = "/srv/parkinghis/insertyiku", method = RequestMethod.POST)
public SrvResult<?> insertyiku(@RequestBody Map<String,Object> map) {
Object reqInfoObject = map.get("requestinfo");
HttpRequestInfo reqInfo = JSON.parseObject(JSON.toJSONString(reqInfoObject), HttpRequestInfo.class);//将传过来

4.如果要传对象，只要把map换成对象即可，但是我这里一直报错。以下是报错以及我要进行传递得类

java.lang.LinkageError: loader constraint violation: when resolving interface method
 "com.macxen.mgmt.client.ParkClientService.insertyiku(Lcom/macxen/zhuang/client/HttpRequestInfo;)

需要传递得类

5.思考:应该是引用jar包当中有重复得类导致，但是全局搜了下，没有重复得。为了安心，marven clean,marven deploy,然后在marven install下载下来，依然没有重复，可是还是报这错，无奈之下换方案之。
