思考

1、查看了服务端口

在这里插入图片描述

查看端口结果是是默认的8080， 我的yml配置里是server.port=88, 我联想到yml配置文件没生效？

server:
  port: 88
 
spring:
  cloud:
    gateway:
      routes:
        - id: pms_route
          uri: lb://gulimall-pms
          predicates:
            - Path=/pms/**, /api/index/**, /api/item/**
          filters:
            # {} 是用来取值的
            - RewritePath=/api/(?<segment>.*), /$\{segment}

        - id: oms_route
          uri: lb://gulimall-oms
          predicates:
            - Path=/oms/**
            # filters:
            # - AddResponseHeader=heyijie,666
        - id: sms_route
          uri: lb://gulimall-sms
          predicates:
            - Path=/sms/**
        - id: ums_route
          uri: lb://gulimall-ums
          predicates:
            - Path=/ums/**, /api/ums/**
          filters:
            # {} 是用来取值的
            - RewritePath=/api/(?<segment>.*), /$\{segment}

        - id: wms_route
          uri: lb://gulimall-wms
          predicates:
            - Path=/wms/**
        - id: gulimall_search_route
          uri: lb://gulimall-search
          predicates:
            # 可能会有特殊字符转义 \{
            - Path=/api/search/**
          filters:
            - RewritePath=/api/(?<segment>.*), /$\{segment}

2、查看编译目录

如图，编译目录果然没有applicaiton.yml文件，springcloud gateway服务直接报错，路由也不生效

在这里插入图片描述

解决

3、修改application.yml重新编译 打包

编译目录下一定要有application.yml

查了一下可能是我application.yml的语法错了，修改了一下，重新编译打包后，编译目录下就有application.yml了，且该配置生效

建议不要添加devtools依赖

这个我也不太清除，加devtools的依赖，在有多个路由的时候，重启服务应用程序 application.yml文件时有时无的，建议还是不要加了, 如果有大佬能指点一二，就更好了

如果application.yml 不在编译目录下，那么访问网关的路由地址就会报错

深入理解 Mocha 测试框架：从零实现一个 Mocha

前言什么是自动化测试自动化测试在很多团队中都是Devops环节中很难执行起来的一个环节，主要原因在于测试代码的编写工作很难抽象，99%的场景都需要和业务强绑定，而且写测试代码的编写工作量往往比编写实际业务代码的工作量更多。在一些很多业务场景中投入产出比很低，适合写自动化测试的应该是那些中长期业务以及一些诸如组件一样的基础库。自动化测试是个比较大的概念，其中分类也比较多，比如单元测试，端对端测试，集

(20200916 Solved)docker-compose up创建容器自动退出

问题描述如题，创建容器后自动退出了。并且docker start container无效解决方案原因是缺失了控制终端的配置，需要在docker-compose.yml中增加tty:true ，有时候这样也不行，需要再增加一个command:/bin/bash，命令不一定是这个，需要是一个不会退出的命令，然后用-d后台启动容器。Referencesdocker-compose启动容器后自动退出...
