1. 打包插件的介绍
打包插件是把class文件,配置文件打包成一个jar(war或者其他格式)的包。而且可执行jar包中包含或者不包含相应的依赖包包,当不包含相应的依赖包时,我们需要建立lib目录,且jar和lib目录在同级别目录。
2. 常见的打包插件
2.1 maven-jar-plugin
可执行jar包与依赖包是分开的,需要建立lib目录来存放所需的依赖包,且jar包与lib目录在同级别目录中,相应的pom配置如下:
- <plugin>
- <groupId>org.apache.maven.plugins</groupId>
- <artifactId>maven-jar-plugin</artifactId>
- <version>2.6</version>
- <configuration>
- <archive>
- <manifest>
- <addClasspath>true</addClasspath>
- <classpathPrefix>lib/</classpathPrefix>
- <mainClass>com.xxx.xxxService</mainClass>
- </manifest>
- </archive>
- </configuration>
- </plugin>
- <plugin>
- <groupId>org.apache.maven.plugins</groupId>
- <artifactId>maven-dependency-plugin</artifactId>
- <version>2.10</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>
2.2 maven-assembly-plugin
该插件会将所有的依赖包放入可执行jar包,但是该插件会缺失spring的xds文件,导致jar包无法运行,而且当同级别目录下还有其他可执行文件依赖可能会产生冲突,相应的pom配置如下:
- <plugin>
- <artifactId>maven-assembly-plugin</artifactId>
- <configuration>
- <descriptorRefs>
- <descriptorRef>jar-with-dependencies</descriptorRef>
- </descriptorRefs>
- <archive>
- <manifest>
- <mainClass>com.xxx.xxxService</mainClass>
- </manifest>
- </archive>
- </configuration>
- <executions>
- <execution>
- <id>make-assembly</id>
- <phase>package</phase>
- <goals>
- <goal>single</goal>
- </goals>
- </execution>
- </executions>
- </plugin>
2.3 maven-shade-plugin
该插件将所有的依赖包放入可执行的jar包中,当同级别目录中有其他的可执行jar包时,依赖可能会产生冲突,且运行jar包时,有时候会出现类似SF,DSA,RSA文件冲突的提示,选哟派相互META-INF目录下的文件,相应pom位置如下:
- <plugin>
- <groupId>org.apache.maven.plugins</groupId>
- <artifactId>maven-shade-plugin</artifactId>
- <version>2.4.3</version>
- <executions>
- <execution>
- <phase>package</phase>
- <goals>
- <goal>shade</goal>
- </goals>
- <configuration>
- <filters>
- <filter>
- <artifact>*:*</artifact>
- <excludes>
- <exclude>META-INF/*.SF</exclude>
- <exclude>META-INF/*.DSA</exclude>
- <exclude>META-INF/*.RSA</exclude>
- </excludes>
- </filter>
- </filters>
- <transformers>
- <transformer
- implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
- <resource>META-INF/spring.handlers</resource>
- </transformer>
- <transformer
- implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
- <resource>META-INF/spring.schemas</resource>
- </transformer>
- <transformer
- implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
- <resource>META-INF/spring.tooling</resource>
- </transformer>
- <transformer
- implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
- <mainClass>com.xxx.xxxInvoke</mainClass>
- </transformer>
- </transformers>
- <minimizeJar>true</minimizeJar>
- <shadedArtifactAttached>true</shadedArtifactAttached>
- </configuration>
- </execution>
- </executions>
- </plugin>
