在进行maven开发时，经常需要进行修改配置信息，如果将所有东西都打包进一个jar文件中，在修改时候不方便，需要重新打包，本文将讲解如果在maven中将jar和resource进行分离，具体操作步骤如下：
- 在pom.xml文件中添加以下插件
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.8.0</version>
<configuration>
<target>1.8</target>
<source>1.8</source>
<encoding>UTF-8</encoding>
</configuration>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>3.1.1</version>
<configuration>
<excludes>
<exclude>*.**</exclude>
<exclude>*/*.xml</exclude>
</excludes>
<archive>
<manifest>
<addClasspath>true</addClasspath>
<classpathPrefix>lib/</classpathPrefix>
<useUniqueVersions>false</useUniqueVersions>
<mainClass>com.xxx.AppStarter</mainClass>
</manifest>
<manifestEntries>
<Class-Path>./conf/</Class-Path>
</manifestEntries>
</archive>
<outputDirectory>${project.build.directory}</outputDirectory>
</configuration>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<version>2.8</version>
<executions>
<execution>
<id>copy-dependencies</id>
<phase>package</phase>
<goals>
<goal>copy-dependencies</goal>
</goals>
<configuration>
<outputDirectory>${project.build.directory}/lib/</outputDirectory>
</configuration>
</execution>
</executions>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-resources-plugin</artifactId>
<version>3.0.2</version>
<executions>
<execution>
<id>copy-resources</id>
<phase>package</phase>
<goals>
<goal>copy-resources</goal>
</goals>
<configuration>
<resources>
<resource>
<directory>src/main/resources</directory>
</resource>
</resources>
<outputDirectory>${project.build.directory}/conf</outputDirectory>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
- 再使用mvn package进行打包
mvn package
-
查看效果
maven分离jar和resource 运行
直接进入此目录，并使用java -jar命令运行
java -jar xxx.jar
