在params字段，我初始取到的数据就是json字符串，此时在经过我的接口 @ReController，导致相应结果多了很多转义字符，类似如下。
｛"params": "{\"autoExtIP\":\"on\",\"BlobUrl\":\"ws://blob.tvupack.com/1\",\"useElasticPublicIp\":\"on\",\"coderiport\":\"\",\"latitude\":\"\",\"available\":\"1\",\"memo\":\"\",\"codereport\":\"\",\"AuthWebUrl\":\"\",\"AuthWebPort\":\"\",\"routingMethod\":\"0\",\"deviceId\":\"1111111111110212\",\"deviceName\":\"chrisrrrrrrrrrr\",\"mineport\":\"10000\",\"GridWebUrl\":\"\",\"iport\":\"\",\"TPDSSendStatusInterval\":\"1\",\"maxiport\":\"30000\",\"tag\":\"\",\"customizedRelay\":\"\",\"Debug\":\"false\",\"longitude\":\"\",\"deviceType\":\"X\",\"eport\":\"\",\"maxeport\":\"30000\",\"miniport\":\"10000\",\"statExternalPort\":\"\",\"LiveSwitchWebUrl\":\"http://liveswitch.tvunetworks.com/tvugs/Tvugs4XServlet\",\"TPDSSendThumbnailInterval\":\"10\",\"statInternalPort\":\"\",\"relayId\":\"\",\"ConstMode\":\"false\",\"GridUpdateInterval\":\"\",\"region\":\"us-east-2\",\"externalIp\":\"1_0_1.0_10.12.22.97\"}"｝
如何解决
