dubbo-admian的打包和平臺搭建

本文簡單介紹下dubbo-admin的搭建過程,包括dubbo-admin的打包細節,以及在打包過程中jdk8的一些坑的解決。


全部程式碼下載:Github連結:github連結,點選驚喜;寫文章不易,歡迎大家採我的文章,以及給出有用的評論,當然大家也可以關注一下我的github;多謝;

1.dubbo-admin介紹:

dubbo-admin從名字可知就是對dubbo進行管理,主要內容包括路由規則,動態配置,服務降級,訪問控制,權重調整,負載均衡,等管理功能。
dubbo的介紹和使用連結

2.下載地址:

3.打包dubbo-admin工程為war

打包其實就是使用maven將dubbo-admin工程變為war可以被Tomact使用的檔案。

3.1.maven和Tomcat安裝:

1.maven安裝:

1.下載我上面的maven軟體
2.然後解壓到特定目錄:apache-maven-3.3.3
3.在path後面追加環境變數:E:\Program Files\eclipse\apache-maven-3.3.3\bin(注意:這是我的地址)
4.測試:在命令視窗下輸入:mvn

2.Tomcat安裝:

1.下載我上面的Tomcat壓縮包
2.直接解壓後就安裝成功

3.2.打包成war檔案

我的jdk8版本和jdk7版本都在之前下載的壓縮檔案中,請各取所需。
1.步驟:

1.開啟命令視窗並cd到dubbo-admin
資料夾(下載的地方) 2.執行mvn package -Dmaven.skip.test=true

打包成功會顯示如下:
00
打包成功之後,就會發現dubbo-admin下多了個target資料夾,開啟target資料夾,裡面有兩個檔案:1.資料夾dubbo-admin-2.5.4-SNAPSHOT和dubbo-admin-2.5.4-SNAPSHOT.war檔案。兩者都可以放入Tomcat,只需要要放一個。
01

3.3除錯與執行:

1.啟動ZooKeeperZooKeeper環境搭建
2.將打包後的檔案dubbo-admin-2.5.4-SNAPSHOT.war或者資料夾拷貝到Tomcat的webapps
3.然後到Tomcat的bin目錄下面雙擊startup.bat,啟動後再點選shutdown.bat停止
4.修改webapps下的dubbo-admin-2.5.4-SNAPSHOT/WEB-INF/dubbo.properties的檔案

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

5.到Tomcat的bin目錄下面雙擊startup.bat
6. 在瀏覽器輸入http://localhost:8080/dubbo-admin-2.5.4-SNAPSHOT/ 注意:我改了資料夾名為dubbo
02
7.輸入密碼後:啟動provider和consumer測試,點選服務

如果可以訪問並且顯示,可以不觀看下面,如果報錯下面或許會有幫助

4.錯誤解決:

4.1打包好後放入Tomcat啟動報錯:

1.錯誤:ERROR context.ContextLoader - Context initialization failed org.springframework.beans.factory.BeanCreationException:
2.主要原因:主要是由於jdk8不能正常執行,切換成jdk8一下的可以執行
3.jdk8解決辦法:

修改pom.xml檔案
1、webx的依賴改為3.1.6版;

    <dependency>
        <groupId>com.alibaba.citrus</groupId>
        <artifactId>citrus-webx-all</artifactId>
        <version>3.1.6</version>
    </dependency>
2、新增velocity的依賴,我用了1.7;

    <dependency>
        <groupId>org.apache.velocity</groupId>
        <artifactId>velocity</artifactId>
        <version>1.7</version>
    </dependency>
3、對依賴項dubbo新增exclusion,避免引入舊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>
參考於:https://github.com/alibaba/dubbo/issues/50

4.2打包時Maven依賴找不到

1.錯誤:[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包不能被公網訪問到
3.解決辦法:
1.根據報的依賴錯修改version
2.下載相應的jar包放到本地倉庫
3.參考網址:https://github.com/alibaba/dubbo/issues/22

4.3我的pom.xml檔案

這個檔案可以被正常打包,jdk8也行
