tomcat上的项目访问出现错误403.

请问,docker部署后如何修改spring boot 的应用配置文件?

  我是个java开发菜鸟,以前一直维护的是spring mvc+tomcat在linux的web项目,最近在学习spring boot +docker(docker-compose),试图改造我手上的Web项目,但遇到一个问题百思不得其解,还希望哪位大神伸手援助。   先说说我的需求,很简单,以前维护pring mvc+tomcat的时候,只是先在Linux部署tomcat、mysql等组件,然后将我的spring应用放至tomcat/webapps下就可以正常运行,因为部署环境不同,该应用经常需要根据现场实际情况,修改web的config等配置文件然后重启,如果应用报错还可以在指定目录下查看项目打印的各类log日志(log4j输出不同的日志)。虽然前期部署麻烦了一些,但有安装脚本什么的,维护起来也方便。  这段时间接触了spring boot +docker以后,也能够将应用通过docker(docker-compose)方式部署起来,但后续的问题怎么也搞不定,比如我想修改应用配置文件中的某一参数,然后重启docker容器就可以正常运行项目,但不知道如何修改application.xml。   我能想到的方法有三种:   1、通过volume将tomcat映射出来,docker-compose配置如下 ``` #docker-compose的版本 version: '3' #定义服务 services: #服务名称,可随意定义 gwqserive: build: #dockerfile的路径 context: gwqapp #dockerfile的名称 dockerfile: appDockerfile #相当于docker run -v的作用 volumes: - "./jar:/tmp" #容器名称 container_name: gwq-compose-app-container #该服务依赖的其他服务,该配置选项可修改启动顺序 depends_on: - mysqldbserver - redisServer links: - mysqldbserver - redisServer ``` appDockerfile: ``` FROM java:8-jre-alpine #维护者信息 MAINTAINER Gaowq VOLUME /tmp ADD SpringBootRedisDemo-0.0.1-SNAPSHOT.jar app.jar #为构建镜像设置监听端口,使容器在运行时监听 EXPOSE 8080 ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"] ``` 好吧,然后容器运行以后,前往/tmp或jar目录下,发现全是tomcat缓存类似的文件,没啥用,跟之前的webapps完全不是一回事  2、想docker exec进去看看,然后。。。一脸meng bi!完全不知道需要的文件在哪  3、我能想到的方式,就是修改好应用配置文件,重新打包jar生成新的镜像,但。。。未免有点太复杂了吧!而且也没有解决我获取不同各类log4j日志的问题。   因为项目最终打包完毕后,将交于专门技术人员安装与维护,故上述情况经常会遇到,由于本人技术太菜,还请各位大神不吝赐教!谢谢!

Docker中的SrpingBoot项目无法访问redis

在本地可以通过Redis的外网IP和密码访问 ![图片说明](https://img-ask.csdn.net/upload/202002/19/1582119339_522394.png) 但是在服务器的docker容器里,连接redis会出错 ![图片说明](https://img-ask.csdn.net/upload/202002/19/1582119485_549362.png) 在服务器上进入redis容器内部开启监控,可以看到通过本地的项目访问redis的记录 ![图片说明](https://img-ask.csdn.net/upload/202002/19/1582119696_974260.png) 但是将这个项目打包成镜像,通过docker起来之后,连接redis,就会报第二张图的错误,其他mysql,rabbitmq都是正常的,很奇怪,求助。。。

Spring clouud eureka feign调用问题

最近在学习使用spring cloud 的时候遇到这样一个问题,项目划分了3个模块 注册中心、服务提供方、服务消费方. 分别启动3个项目后 在注册中心的web管理页面 能看到服务提供方和服务消费方都已经注册上来了。但是 当服务消费方调用方法时,通过日志看到是以服务提供方的别名为IP地址发起调用的 一调用就报错 请各位大神们帮忙看看 最好能给我讲讲为什么会出现这个问题 注册中心启动类 ```/**
