java项目构建部署包

發布時間：2023/12/2 编程问答 36 豆豆
生活随笔 收集整理的這篇文章主要介紹了 java项目构建部署包 小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

  • JAVA

???? Java 工程在生產環境運行時，一般需要構建成一個jar，同時在運行時需要把依賴的jar添加到classpath中去，如果直接運行添加classpath很不方便，比較方便的是創建一個shell腳本。在公司項目中看到把工程代碼和依賴jar包合并到一塊，省去設置classpath的麻煩。但這樣把項目jar依賴綁定死，被其它項目引入，容易造成jar依賴沖突，如果用maven管理java項目，導致提交到公司倉庫jar過于龐大，同時也失去maven對jar依賴管理的作用。
??? 為了方便java項目部署運行，這里為構建部署包定義一個固定格式：

/java 項目
?? /lib??? --存放所有依賴jar
?? /conf?? --存放配置文件，例如：log4j, spring, properties等配置文件，不放入jar是為
???????????? 了方便修改這些配置文件
?? /logs?? --運行時自動創建的目錄，存放日志文件
?? /bin??? --存放運行腳本: server.sh 啟動和停止項目運行。

如果在構建部署包時，需要我們手動去創建這樣的目錄，把文件拷貝相應目錄，實在是太繁瑣了，幸好maven為我們這樣“懶惰”coder提供了一個很好的plugin：maven-assembly-plugin，可以去定制這樣的部署結構

1：配置maven-assembly-plugin

Java代碼 ?
  • <plugin> ??
  • ????<groupId>org.apache.maven.plugins</groupId> ??
  • ????<artifactId>maven-assembly-plugin</artifactId> ??
  • ????<configuration> ??
  • ????????<descriptors> ??
  • ????????????<descriptor>src/main/assembly/assembly.xml</descriptor> ??
  • ????????</descriptors> ??
  • ????</configuration> ??
  • ????<executions> ??
  • ????????<execution> ??
  • ????????????<id>make-assembly</id> ??
  • ????????????<phase>package</phase> ??
  • ????????????<goals> ??
  • ????????????????<goal>single</goal> ??
  • ????????????</goals> ??
  • ????????</execution> ??
  • ????</executions> ??
  • </plugin>??
    • <plugin><groupId>org.apache.maven.plugins</groupId><artifactId>maven-assembly-plugin</artifactId><configuration><descriptors><descriptor>src/main/assembly/assembly.xml</descriptor></descriptors></configuration><executions><execution><id>make-assembly</id><phase>package</phase><goals><goal>single</goal></goals></execution></executions> </plugin>


    2：assembly 配置打包格式

    ? ? 定義在assembly.xml文件中，文件中配置信息不作過多解釋，可以參考相應文檔

    Java代碼 ?
  • <assembly ??
  • ????xmlns="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.2"??
  • ????xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"??
  • ????xsi:schemaLocation="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.2?http://maven.apache.org/xsd/assembly-1.1.2.xsd"> ??
  • ???? ??
  • ????<id>bin</id> ??
  • ????<formats> ??
  • ????????<format>tar.gz</format> ??
  • ????</formats> ??
  • ????<dependencySets> ??
  • ????????<dependencySet> ??
  • ????????????<useProjectArtifact>true</useProjectArtifact> ??
  • ????????????<outputDirectory>lib</outputDirectory> ??
  • ????????????<scope>runtime</scope> ??
  • ????????</dependencySet> ??
  • ????</dependencySets> ??
  • ????<fileSets> ??
  • ????????<fileSet> ??
  • ????????????<outputDirectory>/</outputDirectory> ??
  • ????????????<includes> ??
  • ????????????????<include>README.txt</include> ??
  • ????????????</includes> ??
  • ????????</fileSet> ??
  • ????????<fileSet> ??
  • ????????????<directory>src/main/scripts</directory> ??
  • ????????????<outputDirectory>/bin</outputDirectory> ??
  • ????????????<lineEnding>unix</lineEnding> ??
  • ????????????<fileMode>0755</fileMode> ??
  • ????????????<includes> ??
  • ????????????????<include>*.sh</include> ??
  • ????????????</includes> ??
  • ????????</fileSet> ??
  • ????????<fileSet> ??
  • ????????????<directory>target/classes</directory> ??
  • ????????????<outputDirectory>/conf</outputDirectory> ??
  • ????????????<includes> ??
  • ????????????????<include>*.xml</include> ??
  • ????????????</includes> ??
  • ????????</fileSet> ??
  • ????</fileSets> ??
  • </assembly>??
    • <assemblyxmlns="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.2"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.2 http://maven.apache.org/xsd/assembly-1.1.2.xsd"><id>bin</id><formats><format>tar.gz</format></formats><dependencySets><dependencySet><useProjectArtifact>true</useProjectArtifact><outputDirectory>lib</outputDirectory><scope>runtime</scope></dependencySet></dependencySets><fileSets><fileSet><outputDirectory>/</outputDirectory><includes><include>README.txt</include></includes></fileSet><fileSet><directory>src/main/scripts</directory><outputDirectory>/bin</outputDirectory><lineEnding>unix</lineEnding><fileMode>0755</fileMode><includes><include>*.sh</include></includes></fileSet><fileSet><directory>target/classes</directory><outputDirectory>/conf</outputDirectory><includes><include>*.xml</include></includes></fileSet></fileSets> </assembly>



    下面這段配置主要從src/main/scripts目錄獲取shell腳本復制到bin目錄。同時設置文件模式為unix，文件具有可執行權限。

    Java代碼 ?
  • <directory>src/main/scripts</directory> ??
  • <outputDirectory>/bin</outputDirectory> ??
  • <lineEnding>unix</lineEnding> ??
  • <fileMode>0755</fileMode> ??
  • <includes> ??
  • ????<include>*.sh</include> ??
  • </includes>??
    • <directory>src/main/scripts</directory> <outputDirectory>/bin</outputDirectory> <lineEnding>unix</lineEnding> <fileMode>0755</fileMode> <includes><include>*.sh</include> </includes>

    3：啟動類設計

    在學習metamorphosis的時候，對它的啟動腳本做了一些了解，發現服務stop方式設計比較優雅，通過JMX連接JVM，去關閉系統內部資源，再kill掉進程。

    UeapServerMBean定義stop方法，實現類UeapServer完成系統啟動加載和停止功能。ServerStartup是main方法入口，調用 UeapServer啟動方式，并注冊 UeapServer到JMX中。


    4：啟動腳本

    系統啟動腳本分為了兩個文件：

    env.sh 配置一些環境變量和JVM參數，實際應用中只需要修改 SERVER_NAME、? STARTUP_CLASS和 UEAP_JVM_ARGS變量名稱。

    server.sh 實際運行腳本，提供啟動、停止、運行狀態查詢、重啟功能，實際應用中不需要改動該文件。

    ?

    env.sh

    ?

    ?4：執行mvn install或者mvn package 可以再target生成tar.gz后綴文件。提交到linux系統，解壓縮即可運行。（不考慮window環境）
