将JSON数据从JSP传递到ResponseBody中的控制器时出错.

Ajax调用:

$.ajax({ 
                        url: "/BusinessReimbursment/addDepartment", 
                        method: 'POST', 
                        dataType: 'json', 
                        data: "{\"message\":\"abc\",\"success\":true}",
                        contentType: 'application/json',
                        mimeType: 'application/json',
                        success: function(data) { 
                            alert(data.id + " " …

我的 JavaScript 变量包含一个字符串：

{"start":{"lat":19.0759842,"lng":72.87765630000001},"end":{"lat":18.5206624,"lng":73.8567415},"waypoints":[[18.8753235,73.52948409999999]]}

但是当我将它显示到 HTML 组件中时，它看起来像：

{"start":{"lat":19.0759842,"lng":72.87765630000001},"end":{"lat":18.5206624,"lng":73.8567415},"waypoints":[[18.8753235,73.52948409999999]]}

我的项目中有以下建筑

我的UI服务（端口8080）对网关服务（端口8085）进行虚假调用。
我从UI服务获得的呼叫是“ http：// localhost：8080 / invoice-list？startDate = 2018-08-05＆endDate = 2018-10-05 ”
来自网关服务的类似呼叫“ http：// localhost：8085 / invoice-下载服务/发票清单？startDate = 2018-08-05＆endDate = 2018-10-05 “

当我通过UI服务进行此GET调用时，我在一分钟内收到以下错误消息

 is feign.RetryableException: Read timed out executing GET http://localhost:8085/invoice-download-service/invoice-list?startDate=2018-08-05&endDate=2018-10-05] with root cause

java.net.SocketTimeoutException: Read timed out

但是，当我从网关服务器直接拨打微服务时，我没有收到错误。

网关服务的Application.properties文件

hystrix.command.default.execution.isolation.thread.timeoutInMilliseconds=160000000

ribbon.OkToRetryOnAllOperations=true
ribbon.ReadTimeout=5000000
ribbon.ConnectTimeout=5000000
ribbon.MaxAutoRetries=3
ribbon.MaxAutoRetriesNextServer=3


zuul.host.socket-timeout-millis= 5000000
zuul.host.connect-timeout-millis= 5000000

在这里，我在8到10分钟左右设置了readtimeout和connecttimeout属性，因此我没有收到错误。

UI服务的Application.properties文件

spring.application.name=external-ui-service

server.port=8080

在UI服务中，这里没有超时属性。我在这里尝试了上面的属性，但是没有用。显然，此UI服务未使用功能区，zuul等。这只是对网关的虚假调用。

那么我该怎么做才能增加UI服务的超时时间呢？
