springcloud gateway 项目打包部署运行

新建一个springboot项目然后做了一个小demo跳转到baidu

其中项目同其他随笔上的pom项目，由于springcloud gateway 不能在tomcat运行，所以一定要注释掉web依赖

属性文件：

spring:
  application:
    name: gateway
  cloud:
    nacos:
      discovery:
        server-addr: 192.168.135.129:8848
    gateway:
      routes:
        - id: test-gateway
          uri: http://www.baidu.com
          predicates:
            - Path=/test/**
          filters:
          - StripPrefix=1
server:
  port: 8800

我将该项目注册在nacos上，另外注意

- StripPrefix=1不加的话就会报错，因为跳转后有前缀导致跳转错误不能跳转到百度
本项目搞的是个demo，nacos上没有其他服务，所以启动类上可以不加任何注解去发现注册到nacos上的服务
项目结构如下：

assembly.xml

<?xml version="1.0" encoding="UTF-8"?>

    <!-- 不配置会报错：Assembly ID must be present and non-empty -->
    <id>bin</id>

打包后target目录

部署项目

将tar.gz部署到linux上解压，进入bin文件启动，启动后，开放端口，然后再重新加载一下

注意：启动时候要确保nacos已经启动且端口可以访问

然后查看nacos

浏览器中输入：http://192.168.135.130:8800/test，回车

然后看到跳转至百度页面
