在 AWS ELB 后面带有嵌入式 Undertow 的 Spring Boot - HTTP 到 HTTPS 重定向 [英] Spring Boot with Embedded Undertow behind AWS ELB - HTTP to HTTPS redirect
问题描述
我正在 AWS EC2 实例的端口 8080 上运行 Spring Boot (Jhipster/Undertow) 应用程序.
I'm running a Spring boot (Jhipster/Undertow) application on port 8080 on an AWS EC2 instance.
我有一个配置为重定向的 AWS ELB
I have an AWS ELB configured to redirect
80 -> 8080
443 (SSL termination happens here) -> 8080
应用程序使用 Spring Security,如果您的用户到达 http://example.com 我希望它重定向到 https://example.com,使用 SSL.
The application uses Spring Security and if you user arrives to http://example.com I want it to redirect to https://example.com, to use SSL.
我在中找到了各种配置示例Tomcat 但没有使用 Undertow.
I have found various examples of configuring this in Tomcat but none using Undertow.
我已经尝试过这个,使用第二个端口 8089,它确实根据需要重定向,但这会导致端口 8080 也重定向我不想要的.
I have tried this, with a second port 8089, and it does redirect as required, but this causes port 8080 to also redirects which I don't want.
80 -> 8089
443 (SSL termination happens here) -> 8080
@Bean
public EmbeddedServletContainerFactory undertow() {
UndertowEmbeddedServletContainerFactory undertow = new UndertowEmbeddedServletContainerFactory();
undertow.addBuilderCustomizers(builder -> builder.addHttpListener(8089, "0.0.0.0"));
undertow.addDeploymentInfoCustomizers(deploymentInfo -> {
deploymentInfo.addSecurityConstraint(new SecurityConstraint()
.addWebResourceCollection(new WebResourceCollection()
.addUrlPattern("/*"))
.setTransportGuaranteeType(TransportGuaranteeType.CONFIDENTIAL)
.setEmptyRoleSemantic(SecurityInfo.EmptyRoleSemantic.PERMIT))
.setConfidentialPortManager(exchange -> 443);
});
return undertow;
}
如何配置 Undertow 来实现这一点?
How can I configure Undertow to achieve this?
推荐答案
当我遇到同样的问题时,这对我有用:
This worked for me when I had the same problem:
从 jhipster 中暴露 80 端口(您可以在 application-prod.yml
中更改它).
Expose the port 80 from jhipster (you can change it in the application-prod.yml
).
Amazon ELB 在从 http 重定向到 https 时添加了一些标头,您应该在同一文件中处理这些标头:
Amazon ELB when redirecting from http to https adds some headers, which you should address in the same file:
<代码>服务器:使用转发标题:true端口:80
此外,您需要从 jhipster 强制执行 https:https://jhipster.github.io/tips/007_tips_enforce_https.html
Also, you need to enforce the https from jhipster: https://jhipster.github.io/tips/007_tips_enforce_https.html
