Spring-Boot禁用响应头中的传输编码 [英] Spring-Boot disable transfer-coding from response header

问题描述

问题语句-Spring-Boot(2.0.1.RELEASE和嵌入式Tomcat Server)中的一个简单的RESTful服务返回如下响应，

Problem statement - a simple RESTful service in Spring-Boot (2.0.1.RELEASE, and embedded Tomcat Server) returns response like,

HTTP/1.1 200
Content-Type: application/json;charset=UTF-8
Transfer-Encoding: chunked
Date: Tue, 01 May 2018 00:33:04 GMT

7d
{the-json-response-anticipated}
0

经过查找后，我发现这是由于标头Transfer-Encoding: chunked引起的.尝试在application.properties

After a search-and-find, I found that this is caused due to the header Transfer-Encoding: chunked. Tried setting the following in application.properties

spring.http.encoding.force=false
spring.http.encoding.enabled=false

但是，没有用.有什么办法可以禁用相同的功能吗?
我应该编写显式代码以将参数设置为false的标题形成标题，并将其设置为响应的标题吗?

But, to no use. Any means to disable the same ?
Should I write explicit code to form a header with the parameter set asfalse and set it to the header of the response ?

推荐答案

这可以通过显式添加HttpHeaders.CONTENT_LENGTH标头来实现，如下所示:

This can be achieved by explicitly adding the HttpHeaders.CONTENT_LENGTH header like the below:

一个例子:

@RequestMapping(value = "/contacts", method = RequestMethod.POST)
public Map<String, ContactInfo> addContactInfo(
                            @RequestBody Map<String, ContactInfo> ContactInfoDto,    
                            @RequestHeader(value = HttpHeaders.CONTENT_LENGTH, required = true) Long contentLength)
{ 
    ... 
}
