[BUG] <title>Incomplete data returned

### Is there an existing issue for this?

- [X] I have searched the existing issues

### Current Behavior

返回数据比较多，经过网关时候被截断了，前端接收数据不全，比如：

"names": [
{
"language": "en-US",
"name": "12122"
},
{
"language": "zh-CN",
"name": "21212"
}
],
"sort": 14,
"status": 1
}
],
"message": "Success",
"success"

这个是我这边的打印结果，理论上完整大数据还有

### Expected Behavior

{
"cateCode": "G",
"children": [],
"id": 31,
"name": "12122",
"names": [
{
"language": "en-US",
"name": "12122"
},
{
"language": "zh-CN",
"name": "21212"
}
],
"sort": 14,
"status": 1
}
],
"message": "Success",
"success": true
}

这个是期望的结尾， 是一个完整的json数据

### Steps To Reproduce

_No response_

### Environment

```markdown

org.apache.shenyu

### Anything else?

有3个怀疑：
1. 返回数据被截断了，可能是返回数据量有限制，这个需要怎么调整
2. 返回数据被截断了，可能是块传输机制导致的，这个需要怎么配置
3. 返回数据不是截断了，而是有一层拦截器，并且这块对json解析有问题，导致漏了最后的

Start with the shenyu-spring-boot-starter-sync-data-center entry point at version 2.6.1 and reproduce the large response through the gateway. Trace where the JSON response is truncated; done means the frontend receives the complete valid JSON, including the final success field.
