CSE版本：3.1.5 ServiceComb版本：2.1.2 Jackson版本：2.11.0
业务代码：
```
API接口
public interface ApiInterface {
QueryRsp query(@Valid QueryParam queryParam);
}
API实现类
@RestSchema(schemaId = "apiImpl")
@Path("")
@Consumes({MediaType.APPLICATION_JSON, MediaType.TEXT_XML})
@Produces({"application/json; charset=UTF-8", "text/xml; charset=UTF-8"})
public class ApiImpl {
@GET
@Path("/query")
@Override
QueryRsp query(@BeanParam QueryParam queryParam) {
//TODO
}
}
QueryParam
@Data
public class IncidentLogQueryParam{
@QueryParam("params")
private List<@NotNull Integer> params;
}
```
浏览器请求：
`http://localhost:8080/query?params=`
结果:
`params:[null]`
另外新增Post接口
业务代码：
`Param private List<String> params`
请求参数：
`{
params: ''
}`
结果:
`params:[""]`
