[GitHub] [servicecomb-java-chassis] zhufeizzz opened a new issue #1837: 2.0.2使用highway调用时报“Could not parse syntax”
zhufeizzz opened a new issue #1837:
URL: https://github.com/apache/servicecomb-java-chassis/issues/1837
客户端和服务端版本都是2.0.2
接口声明如下：
```
@RequestMapping(path = "/simple", method = RequestMethod.GET)
@Override
public String testSimple(String input) {
return input;
}
```
错误日志如下：

ApplicationID是demo，冒号是ServiceComb自己拼的

你的接口定义和下面的异常消息看不出来有任何关联。 能否先使用一个简单DEMO验证下你的使用方式？避免复杂系统的影响。

@liubao68 找到问题了
是因为这里：“package demo:cse_perf_test_server.HighwayPerfTestService;”，因为ApplicationID后面是冒号，不符合语法规范，请看下怎么换一个分隔符。

按照你说的，这个问题应该是必现的问题，但实际不是。 是不是你的客户端的代码比较特殊， 能共享下你的客户端代码是怎么发起对这个服务的调用的吗？

It's a bit strange, I can not reproduce your problem. [see my code here ](https://github.com/liubao68/java-chassis/commit/c95c032cefd7c64ae22b937e86b3ad8b1d1c85d0

Invoker.createProxy("demo:cse-perf-test-server", "PerfTestService", PerfTestService.class);
通过这种方式调用，当指定ApplicationID时不行，如果大家ApplicationID一样不用指定则没问题

@liubao68 我又建了一个极简的接口一样报错
接口定义：
```
@RestSchema(schemaId = "HighwayPerfTestService")
@RequestMapping(path = ServiceConstants.SERVICE_URL_PREFIX + "/highway-perf")
public class HighwayPerfTestServiceImpl implements HighwayPerfTestService {
@RequestMapping(path = "/empty", method = RequestMethod.GET)
@Override
public String testEmpty() {
return "";
}
@RequestMapping(path = "/simple", method = RequestMethod.GET)
@Override
public String testSimple(String input) {
return input;
}
}
```
错误日志：
```

看起来不是你发的接口的影响导致的错误，是其他接口。 比如： BaseInstance 里面采用的 JSONObject 参数。 可以试试是不是由于这个接口影响的。
