java项目构建部署包

發(fā)布時間：2023/12/2 编程问答 34 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(xiàn)在分享給大家,幫大家做個參考.

JAVA

???? Java 工程在生產(chǎn)環(huán)境運行時，一般需要構(gòu)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(chuàng)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(shè)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(dǎo)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(gòu)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(chuàng)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(gòu)建部署包時，需要我們手動去創(chuàng)建這樣的目錄，把文件拷貝相應(yīng)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(jié)構(gòu)

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(yīng)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(fù)制到bin目錄。同時設(shè)置文件模式為unix，文件具有可執(zhí)行權(quán)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(shè)計

在學(xué)習(xí)metamorphosis的時候，對它的啟動腳本做了一些了解，發(fā)現(xiàn)服務(wù)stop方式設(shè)計比較優(yōu)雅，通過JMX連接JVM，去關(guān)閉系統(tǒng)內(nèi)部資源，再kill掉進程。

UeapServerMBean定義stop方法，實現(xiàn)類UeapServer完成系統(tǒng)啟動加載和停止功能。ServerStartup是main方法入口，調(diào)用 UeapServer啟動方式，并注冊 UeapServer到JMX中。

4：啟動腳本

系統(tǒng)啟動腳本分為了兩個文件：

env.sh 配置一些環(huán)境變量和JVM參數(shù)，實際應(yīng)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(tài)查詢、重啟功能，實際應(yīng)用中不需要改動該文件。

env.sh

?4：執(zhí)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(tǒng)，解壓縮即可運行。（不考慮window環(huán)境）
