maven多模块工程打包部署的方法步骤

本篇文章主要介绍了maven多模块工程打包部署的方法步骤，小编觉得挺不错的，现在分享给大家，也给大家做个参考。一起跟随小编过来看看吧

 

一般maven多模块工程结构如下图，图中分为dao数据层和上层web层(当然还可以有service层),在进行多模块划分的时候，一般将dao层采用jar进行打包，web层进行war打包。在进行war包部署时，发现dao是以jar包形式存在于lib包目录下，如果在部署服务器上需要进行相关配置修改会比较麻烦。因此研究了下用maven进行合并打包的方法：

1.确保dao pom.xml中有以下配置

1 2 3 4 5 6 7 8 9 10 11 12

<resources>   <resource>     <directory>${basedir}/src/main/javadirectory>     <includes>       <include>**/*.xmlinclude>       <include>**/*.propertiesinclude>     includes>   resource>   <resource>     <directory>${basedir}/src/main/resourcesdirectory>   resource> resources>

2.在dao目录下执行：mvn clean install -Dmaven.test.skip=true,以生成jar包

3.在web工程pom.xml添加以下插件配置

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25

<plugin>   <groupId>org.apache.maven.pluginsgroupId>   <artifactId>maven-dependency-pluginartifactId>   <executions>     <execution>       <id>unpackid>       <phase>generate-resourcesphase>       <goals>         <goal>unpackgoal>       goals>       <configuration>         <artifactItems>           <artifactItem>             <groupId>com.testgroupId>             <artifactId>daoartifactId>             <version>1.0version>             <type>jartype>             <overWrite>trueoverWrite>             <outputDirectory>./target/classesoutputDirectory>           artifactItem>         artifactItems>       configuration>     execution>   executions> plugin>

上述插件表示将dao-1.0.jar解压至web工程的target/classes目录中(即工程编译源码目录)

4.运行web工程，即可发现dao相关配置文件及源码已合并过来。（注意，此时在默认的war包的lib中还会包含dao的jar）

若还需要对war工程进行jar打包部署，则在web工程pom.xml中添加jar打包插件即可

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22

<plugin>   <groupId>org.apache.maven.pluginsgroupId>   <artifactId>maven-jar-pluginartifactId>   <executions>     <execution>       <id>1id>       <phase>packagephase>       <goals>         <goal>jargoal>       goals>       <configuration>         <classesDirectory>./target/classesclassesDirectory>         <excludes>           <exclude>*.propertiesexclude>           <exclude>*.xmlexclude>         excludes>         <finalName>webfinalName>         <outputDirectory>./target/WEB-INF/liboutputDirectory>       configuration>     execution>   executions> plugin>

加入后，在web下重新执行mvn install命令，会在target/WEB-INF/lib目录下生成web.jar文件,jar中不包含properties和xml文件(去掉excludes，默认情况下会将所有文件进行打包)。

在上面情况下并没有将配置文件打包，因此需要将配置文件进行拷贝：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48

<plugin>   <groupId>org.apache.maven.pluginsgroupId>   <artifactId>maven-resources-pluginartifactId>   <version>2.4.3version>   <executions>     <execution>       <id>copy-resourcesid>       <phase>packagephase>       <goals>         <goal>copy-resourcesgoal>       goals>       <configuration>         <encoding>UTF-8encoding>         <outputDirectory>./target/WEB-INF/classesoutputDirectory>         <resources>           <resource>             <directory>./target/classesdirectory>             <includes>               <include>*.propertiesinclude>             includes>             <filtering>truefiltering>           resource>         resources>       configuration>     execution>          <execution>       <id>copy-web-xmlid>       <phase>packagephase>       <goals>         <goal>copy-resourcesgoal>       goals>       <configuration>         <encoding>UTF-8encoding>         <outputDirectory>./target/WEB-INFoutputDirectory>         <resources>           <resource>             <directory>./src/main/webapp/WEB-INFdirectory>             <includes>               <include>*.xmlinclude>             includes>             <filtering>truefiltering>           resource>         resources>       configuration>     execution>   executions> plugin>

通过上面配置方式，则可将配置文件拷贝至target/WEB-INF/classes目录下

通过上述配置，对于web工程部署，还缺少所依赖的其他jar包，因此需要将jar包拷贝过来(同时去除依赖的dao)：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

<plugin>   <groupId>org.apache.maven.pluginsgroupId>   <artifactId>maven-dependency-pluginartifactId>   <executions>     <execution>       <id>copyid>       <phase>installphase>       <goals>         <goal>copy-dependenciesgoal>       goals>       <configuration>         <outputDirectory>./target/WEB-INF/liboutputDirectory>         <excludeGroupIds>com.testexcludeGroupIds>       configuration>     execution>   executions> plugin>

通过以上步骤可在target目录看到web常规工程部署结构：
