超时动态 HTTP 出站网关请求工厂 [英] timeout dynamic HTTP outbound gateway request-factory

问题描述

我已经为 HTTP 出站网关配置了超时，使用 request-factory 属性提供对 ClientHttpRequestFactory bean 的引用:

I have configured timeouts for the HTTP Outbound Gateway providing a reference to a ClientHttpRequestFactory bean using the request-factory attribute:

<int-http:outbound-gateway request-channel="channelGetByCustomer"
    request-factory="requestFactoryGetByCustomer"
    reply-channel="jsonToObjectChannel" url="${getbycustomer.endpoint.url}"
    http-method="GET" expected-response-type="com.mbracero.integration.dto.Item[]">

    <int-http:uri-variable name="customerid" expression="payload.customerid"/>

</int-http:outbound-gateway>

<beans:bean id="requestFactoryGetByCustomer" class="org.springframework.http.client.SimpleClientHttpRequestFactory">
    <beans:property name="connectTimeout" value="${getbycustomer.timeout}"/>
    <beans:property name="readTimeout" value="${getbycustomer.timeout}"/>
</beans:bean>

但我想从 DDBB(或以编程方式)而不是从 Spring 初始启动动态加载这些属性.

But I want to load these attributes dynamically from DDBB (or programmatically) and not from Spring initial boot.

我该怎么做?

推荐答案

您可以通过编程方式执行此操作，只需从您的任何服务注入 requestFactoryGetByCustomer bean 并使用其设置器即可:

Programmatically you can do that just from any your service injecting that requestFactoryGetByCustomer bean and using its setters:

@Autowired
private SimpleClientHttpRequestFactory requestFactoryGetByCustomer;

....

this.requestFactoryGetByCustomer.setConnectTimeout(30_000);

要从 DB 中读取这些选项并使用 Spring Container 功能将它们填充到 bean 定义中(例如在您当前的情况下的属性占位符)，您应该查看 Commons Configuration 框架并从 DB SELECT 填充 Properties 对象代码>.

To read those options from the DB and populate them to the bean definition using Spring Container features (e.g. Property Placeholder like in your current case) you should take a look to the Commons Configuration framework and populate Properties object from the DB SELECT.
