Idea打包的多种方式研究
Idea打包方式
- 打一个empty只包含编译文件的包，artifact===> 点击+ ====> jar =====> Empty ===> Output layout ===> 选择相关模块下的 complie output即可
- 打包一个Empty包含编译文件和依赖的包，artifact===> 点击+ ====> jar =====> Empty ===> Output layout ===> 选择相关模块下的 complie output&& 相关依赖【extratct into output root】
- 打包一个带有main方法的jar包，artifact===> 点击+ ====> jar =====> From modules with dependcies ===> 选择module main方法类
- 运行方式
- java -cp jar包 com.test.main主类
- java -jar jar包
Maven打包方式
- maven-jar-plugin,打出来是一个不包含依赖的包几十kb大小
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>3.0.2</version>
<configuration>
<archive>
<addMavenDescriptor>false</addMavenDescriptor>
<manifest>
<addClasspath>true</addClasspath>
<classpathPrefix>lib/</classpathPrefix>
<mainClass>com.test</mainClass>
</manifest>
<manifestEntries>
<Class-Path>./</Class-Path>
</manifestEntries>
</archive>
<!-- 过滤掉不希望包含在jar中的文件 -->
<excludes>
<!-- <exclude>*.xml</exclude>-->
<!-- <exclude>spring/**</exclude>-->
<!-- <exclude>config/**</exclude>-->
</excludes>
<!-- <includes>-->
<!-- <include>**.keytab</include>-->
<!-- <include>*.conf</include>-->
<!-- </includes>-->
</configuration>
</plugin>
- maven-assembly-plugin打包方式，打出来也是一个不包含依赖的包，几十kb大小
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-assembly-plugin</artifactId>
<configuration>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
<archive>
<manifest>
<mainClass>com.test</mainClass>
</manifest>
</archive>
</configuration>
<executions>
<execution>
<id>make-assembly</id>
<phase>package</phase>
<goals>
<goal>single</goal>
</goals>
</execution>
</executions>
</plugin>
3.maven-shade-plugin可以打包出来一个包含依赖的包
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
<version>3.0.0</version>
<executions>
<!-- Run shade goal on package phase -->
<execution>
<phase>package</phase>
<goals>
<goal>shade</goal>
</goals>
<configuration>
<artifactSet>
<excludes>
<exclude>org.apache.flink:force-shading</exclude>
<exclude>com.google.code.findbugs:jsr305</exclude>
<!-- <exclude>org.slf4j:*</exclude>-->
<!-- <exclude>log4j:*</exclude>-->
</excludes>
</artifactSet>
<filters>
<filter>
<!-- Do not copy the signatures in the META-INF folder.
Otherwise, this might cause SecurityExceptions when using the JAR. -->
<artifact>*:*</artifact>
<excludes>
<exclude>META-INF/*.SF</exclude>
<exclude>META-INF/*.DSA</exclude>
<exclude>META-INF/*.RSA</exclude>
<exclude>resources</exclude>
</excludes>
</filter>
</filters>
<transformers>
<transformer
implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
<mainClass>com.test</mainClass>
</transformer>
</transformers>
</configuration>
</execution>
</executions>
</plugin>
