Jackson在处理字符串时存在长度限制，是否可以添加配置项，供业务控制其所能解析的字符传长度？

当前遇到一个问题，是服务端返回的响应消息中，字符串长度过长，导致jackson解析失败
```

```
20000000是jackson提供的默认值；从chassis源码中来看，并没有提供配置该长度的配置项，是否可以加一个

跟踪从 ProduceJsonProcessor.doDecodeResponse 经过 ProduceProcessor.decodeResponse 到 DefaultHttpClientFilter.extractResponse 的响应解码过程，重点关注 Jackson 的 StreamReadConstraints 对字符串长度的验证。确定可以在哪里配置服务级别的最大字符串长度，然后验证在解码超大响应时会遵守已配置的限制。
