本文简单介绍下dubbo-admin的搭建过程,包括dubbo-admin的打包细节,以及在打包过程中jdk8的一些坑的解决。

1.dubbo-admin介绍:

dubbo-admin从名字可知就是对dubbo进行管理,主要内容包括路由规则,动态配置,服务降级,访问控制,权重调整,负载均衡,等管理功能。 dubbo的介绍和使用链接

2.下载地址:

官网地址: https://github.com/alibaba/dubbo 我的地址:有修改pom.xml文件方便jdk8打包 tomcat和maven安装下载:http://download.csdn.net/detail/peace1213/9645188 dubbo-admin配套下载:http://download.csdn.net/detail/peace1213/9645191

3.打包dubbo-admin工程为war

打包其实就是使用maven将dubbo-admin工程变为war可以被Tomact使用的文件。

3.1.maven和Tomcat安装:

1.maven安装:

1.下载我上面的maven软件 2.然后解压到特定目录:apache-maven-3.3.3 3.在path后面追加环境变量:E:\PRogram Files\eclipse\apache-maven-3.3.3\bin(注意:这是我的地址) 4.测试:在命令窗口下输入:mvn

2.Tomcat安装:

1.下载我上面的Tomcat压缩包 2.直接解压后就安装成功

3.2.打包成war文件

我的jdk8版本和jdk7版本都在之前下载的压缩文件中,请各取所需。 1.步骤:

1.打开命令窗口并cd到dubbo-admin文件夹(下载的地方) 2.执行mvn package -Dmaven.skip.test=true

打包成功会显示如下: 00 打包成功之后,就会发现dubbo-admin下多了个target文件夹,打开target文件夹,里面有两个文件:1.文件夹dubbo-admin-2.5.4-SNAPSHOT和dubbo-admin-2.5.4-SNAPSHOT.war文件。两者都可以放入Tomcat,只需要要放一个。 01

3.3调试与运行:

1.启动ZooKeeperZooKeeper环境搭建 2.将打包后的文件dubbo-admin-2.5.4-SNAPSHOT.war或者文件夹拷贝到Tomcat的webapps 3.然后到Tomcat的bin目录下面双击startup.bat,启动后再点击shutdown.bat停止 4.修改webapps下的dubbo-admin-2.5.4-SNAPSHOT/WEB-INF/dubbo.properties的文件

dubbo.registry.address=zookeeper://127.0.0.1:2181##zk地址 dubbo.admin.root.passWord=root##root密码 dubbo.admin.guest.password=guest##guest密码

5.到Tomcat的bin目录下面双击startup.bat 6. 在浏览器输入http://localhost:8080/dubbo-admin-2.5.4-SNAPSHOT/ 注意:我改了文件夹名为dubbo 02 7.输入密码后:启动provider和consumer测试,点击服务 04 05 05 05 如果可以访问并且显示,可以不观看下面,如果报错下面或许会有帮助

4.错误解决:

4.1打包好后放入Tomcat启动报错:

1.错误:ERROR context.ContextLoader - Context initialization failed org.springframework.beans.factory.BeanCreationException: 2.主要原因:主要是由于jdk8不能正常运行,切换成jdk8一下的可以运行 3.jdk8解决办法:

修改pom.xml文件 1、webx的依赖改为3.1.6版; <dependency> <groupId>com.alibaba.citrus</groupId> <artifactId>citrus-webx-all</artifactId> <version>3.1.6</version> </dependency> 2、添加velocity的依赖,我用了1.7; <dependency> <groupId>org.apache.velocity</groupId> <artifactId>velocity</artifactId> <version>1.7</version> </dependency> 3、对依赖项dubbo添加exclusion,避免引入旧spring <dependency> <groupId>com.alibaba</groupId> <artifactId>dubbo</artifactId> <version>${project.parent.version}</version> <exclusions> <exclusion> <groupId>org.springframework</groupId> <artifactId>spring</artifactId> </exclusion> </exclusions> </dependency> 参考于:https://github.com/alibaba/dubbo/issues/50

4.2打包时Maven依赖找不到

1.错误:[ERROR] Failed to execute goal on project dubbo-common: Could not resolve dependencies for project 2.原因:dubbo-admin工程下pom.xml中有些jar包不能被公网访问到 3.解决办法: 1.根据报的依赖错修改version 2.下载相应的jar包放到本地仓库 3.参考网址:https://github.com/alibaba/dubbo/issues/22

4.3我的pom.xml文件

这个文件可以被正常打包,jdk8也行
