[GitHub] [servicecomb-java-chassis] hypggg opened a new issue #2130: java.lang.IllegalStateException: not allow complex type for query parameter, type=java.util.List.
hypggg opened a new issue #2130:
URL: https://github.com/apache/servicecomb-java-chassis/issues/2130
GET 请求里边有List参数怎么办？ Get没有requestBody
这个https://github.com/apache/servicecomb-java-chassis/issues/1737 没办法解决get的问题，

参数有点多，所以就封装了个对象，这是要把这种方法都改成post吗？

我们是定义的对象，对象中包含了List<Integer>,代码如下：
@RequestMapping(
value = "/XXXX",
produces = { "application/json" },
method = RequestMethod.GET)
public ResponseEntity<byte[]> exportXXXX(
@Valid OpOrderReq opOrderReq)
throws Exception
{
XXXX;
}
OpOrderReq类包含了这种字段，还有其它基本类型字段
@Valid
@JsonProperty("status_array")
private List<Integer> statusArray = new ArrayList<Integer>();
这种还不是直接传了List<String>类型的参数，这个要怎么改

`List<String>`这种是合法的
但是`List<User>`这种复杂类型是不可以的，没办法编码，并且这些复杂类型在url上传输，可能还涉及敏感信息泄漏的问题
如果服务自行评估，不存在信息泄漏，可以尝试使用2.1.3版本中新增加的query参数json编解码功能
（增加这个功能仅仅为了兼容某些系统的陈旧接口，没有特殊情况，不建议使用）
```java
@GetMapping("queryArrJSON")
public String queryArrJSON(@ApiParam(collectionFormat = "json") @RequestParam("queryArr") String[] queryArr) {
return Arrays.toString(queryArr) + queryArr.length;
}
```
https://github.com/apache/servicecomb-java-chassis/blob/master/integration-tests/it-producer/src/main/java/org/apache/servicecomb/it/schema/DataTypeSpringmvcSchema.java
如果还需要其他query codec，可以自行实现自己的QueryCodec

如果是这个场景，在2.1.3版本中，我们是这样用的：
```java
public class SomeAggrParam {
@ApiParam(value = "query lists的描述")
@QueryParam("query_lists")
private List<String> queryLists;
@ApiParam(value = "header name的描述")
@HeaderParam("header_name")
private String headerName;
其他参数定义
getter/setter
}
@RequestMapping(path = "......")
public class MyController {
@GetMapping(path = "......")
public String query(@BeanParam SomeAggrParam param) {
return ......;
}
｝
```
这里使用的是jax-rs标准中的@BeanParam参数聚合特性
在servicecomb最新版本中，无论是jax-rs，还是springmvc开发模式，均可使用这个特性

说实在的，我真的无法理解，为何要这样将对象在url上传递，这是相当不规范的做法……
