基于consul的注册发现的微服务架构迁移到servicemesh_springcloud consul 服务往 istio 迁移

现有的服务架构，是基于consul、springcloud gateway的一套微服务架构，近期公司也是打算把所有的系统都迁移到servicemesh上，所以我们系统涉及到一次架构变更。

变更的内容如下

//@FeignClient(name = "pcms-uniquerypolicy", path = "pcms/uniquery/policyapp/rest")
//@FeignClient(name = "pcms-uniquerypolicy", url = "http://localhost:19001/pcms/uniquerypolicy/policyapp/rest")
//@FeignClient(name = "pcms-uniquerypolicy", path = "pcms/uniquerypolicy/policyapp/rest")
//@FeignClient(name = "pcms-uniquerypolicy",path = "http://10.30.59.14:9002/pcms/uniquerypolicy")
//@FeignClient(name = "testClient",path = "http://10.30.59.14:9002/pcms/uniquerypolicy/policyapp/rest")
//@FeignClient(value = "testClient",path = "http://10.30.59.14:9002/pcms/uniquerypolicy/policyapp/rest")
@FeignClient(name = "pcms-uniquerypolicy",url = "http://localhost:19001/pcms/uniquerypolicy/policyapp/rest")
public interface PolicyCbpsApi {
 
@RequestLine(value = "POST /stdContract/getStdContractBOList")
List<StdContractBO> getStdContractBOList(
       @Param(value = "stdContractQRY") StdContractQRY stdContractQRY, @Param(value = "routeInfo") RouteInfo route);
 
}
//@FeignClient(name = "pcms-uniquery-gateway")
@FeignClient(name = "pcms-uniquery-gateway",url="http://localhost:19001")
public interface CpnstApi {
 
   /**
    * @throws
    * @Title: getCpnstApplList
    * @param: @param appl
    * @param: @param sysNo
    * @param: @param branchNo
    * @param: @return
    * @return: List<CpnstApplPO>
    */
   @RequestMapping(value = ConstUtil.CONTEXT_PATH+"/cpnstAppl/getCpnstApplList", method = RequestMethod.POST, produces = "application/json; charset=utf-8")
   List<CpnstApplPO> getCpnstApplList(@RequestBody CpnstApplQRY appl, @PathVariable(value = "sysNo") String sysNo, @PathVariable(value = "branchNo") String branchNo);
}
 
public class ConstUtil {
   private ConstUtil(){}
//    public static final String CONTEXT_PATH="/pcms-uniquery{sysNo}{branchNo}/pcms/uniquery/{sysNo}-{branchNo}/daoapp/rest";
   public static final String CONTEXT_PATH="/pcms/uniquery{sysNo}{branchNo}/{sysNo}-{branchNo}/daoapp/rest";
   public static final String EXT_FLAG = "1"; // 附加险标识
}

1. 之前用的FeignClient中的path匹配，path=contextPath+server.servlet.path，用于定义当前FeignClient的统一前缀
2. 现在改为url，官方文档里面url的解释是 an absolute URL or resolvable hostname,绝对路径的url或者可解析的主机名。localhost:19001，网格中的默认端口，而后面两段定义的是rancher里面服务的系统名+service_name，最后两段是server.servlet.path
