springcloud网关属性文件声明变量

Question

我在springboot应用程序中有application.yaml，如下所示

spring:
  cloud:
    gateway:
      routes:
      - id: pgService
        uri: http://localhost:2005/
        predicates:
        - Path=/employee/**
      - id: inMateService
        uri: http://localhost:2006/
        predicates:
        - Path=/consumer/**

上面声明的变量是与spring云网关相关的

我想在application.properties文件中声明这些相同的变量。我不想使用yaml文件。请帮我实现这一点谢谢

Answer 1

您可以在application.properties文件中按如下方式定义变量：

spring.cloud.gateway.routes[0].id=pgService
spring.cloud.gateway.routes[0].uri=http://localhost:2005/
spring.cloud.gateway.routes[0].predicates[0]=Path=/employee/**
spring.cloud.gateway.routes[1].id=inMateService
spring.cloud.gateway.routes[1].uri=http://localhost:2006/
spring.cloud.gateway.routes[1].predicates[0]=Path=/consumer/**

刚刚更新了ans。

它应该类似于下面的格式：

spring.cloud.gateway.discovery.locator.predicates[0].name: Path
spring.cloud.gateway.discovery.locator.predicates[0].args[pattern]: "'/'+serviceId+'/**'"
spring.cloud.gateway.discovery.locator.predicates[1].name: Host
spring.cloud.gateway.discovery.locator.predicates[1].args[pattern]: "'**.foo.com'"
spring.cloud.gateway.discovery.locator.filters[0].name: Hystrix
spring.cloud.gateway.discovery.locator.filters[0].args[name]: serviceId
spring.cloud.gateway.discovery.locator.filters[1].name: RewritePath
spring.cloud.gateway.discovery.locator.filters[1].args[regexp]: "'/' + serviceId + '/(?<remaining>.*)'"
spring.cloud.gateway.discovery.locator.filters[1].args[replacement]: "'/${remaining}'"

参考https://cloud.spring.io/spring-cloud-gateway/multi/multi__configuration.html

如果你使用的是intelliJ，下面的插件对在.yaml和.properties之间转换格式很有帮助：https://plugins.jetbrains.com/plugin/13804-convert-yaml-and-properties-file

这对我很管用

spring.cloud.gateway.routes[0].id=USER-SERVICE
spring.cloud.gateway.routes[0].uri=lb://USER-SERVICE
spring.cloud.gateway.routes[0].predicates[0].name=Path
spring.cloud.gateway.routes[0].predicates[0].args[pattern]=/user/**

spring.cloud.gateway.routes[1].id=USER-SERVICE
spring.cloud.gateway.routes[1].uri=lb://USER-SERVICE
spring.cloud.gateway.routes[1].predicates[0].name=Path
spring.cloud.gateway.routes[1].predicates[0].args[pattern]=/department/**
