Spring Cloud Gateway背后的Camunda没有返回驾驶舱的CSS文件
Spring Cloud Gateway背后的Camunda没有返回驾驶舱的CSS文件

我有一个嵌入在Spring Boot应用程序中的Camunda实例(称为服务工作流)，它在动态端口上启动，并通过Eureka注册到Spring Cloud。
Camunda服务的主类很简单：
@EnableDiscoveryClient
@SpringBootApplication
@EnableConfigurationProperties(ServiceContextConfig.class)
public class WorkflowServiceApplication {
public static void main(String[] args) {
SpringApplication.run(WorkflowServiceApplication.class, args);
}
}和配置属性：
server.port=0
eureka.client.healthcheck.enabled=true这些服务位于本地Spring Cloud Gateway后面，该网关在使用尤里卡注册主机的端口上运行，并且可以通过http://localhost:8080访问和路由
网关的代码为：
@SpringBootApplication
@EnableDiscoveryClient
public class GatewayServiceApplication {
public static void main(String[] args) {
SpringApplication.run(GatewayServiceApplication.class, args);
}
}和配置属性：
server.port=8080
spring.cloud.gateway.discovery.locator.enabled=true
spring.cloud.gateway.discovery.locator.lowerCaseServiceId=true没有定义路由-它完全依赖于Eureka来查找路由。这对于REST连接来说是没有问题的。
任何使用runtimeService的客户端都可以使用带有URL: feign.client.config.remoteRuntimeService.url=service-workflow/rest/的feign启动工作流
因此，可以通过REST API的网关URL访问工作流服务。
当Camunda服务启动，并获得分配的端口x时，我可以通过http://localhost:x/app/cockpit/default/查看驾驶舱。但是，如果我尝试通过网关，即http://localhost:8080/service-workflow/app/cockpit/default/，它无法返回任何CSS文件-网关日志显示：

我最终解决这个问题的方法是在网关中添加一个自定义路由：
.route("camunda", r -> r.path("/camunda/**")
//.filters(f -> f.rewritePath("/report/(?<segment>.*)", "/${segment}"))
.uri("lb://my-camunda-service"))页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
