使用版本 2.2.0

问题： xxl-rpc json解析失败

2.2.0版本xxl-rpc调用api/registry结果返回json为 { "code": 200, "msg": "", "content": {} } 结果显示xxl-rpc json解析失败。完整信息是： `2020-07-09 17:25:01.905 ERROR 21564 --- [rRegistryThread] c.xxl.job.core.util.XxlJobRemotingUtil : xxl-rpc remoting (url=http://localhost:8400/xxl-job-admin/api/registry) response content invalid({"code":200,"msg":"","content":{}}).

可能原因

由于AdminBizClient的registry方法结果json结果参数解析为String.class，导致content为空json解析为String失败 @Override public ReturnT<String> registry(RegistryParam registryParam) { return XxlJobRemotingUtil.postBody(addressUrl + "api/registry", accessToken, timeout, registryParam, String.class); } 请问这个问题怎么解决 @xuxueli？
