mvn生成runnablejar 的方法

2015-10-12 10:15 483 查看

主要讲3点，生成runnablejar方法1是生成一个目录方法2是直接一个runnable的jar方法3是关于包含spring工程的情况方法2和3其实是一致的

1、生成runnablejar，但是最后并不是一个可执行的jar而是一个目录

主要使用三个插件将所需要的资源拷贝到/target/Crunchify目录下，注意并没有生成一个jar中去

maven-resources-plugin

maven-dependency-plugin

maven-jar-plugin

togenerateyourcompleteexecutableJarProject?Asaresultitcreates/copiesallrequiredfilesto

/target/Crunchify

folder.

pom文件如下：注意build标签下的3个plugins<build>

<pluginManagement>
<plugins>
<plugin>

<finalName>Crunchify/Crunchify</finalName>
</configuration>

</build>

最后看看结果

2、生成到一个jar包中，这个时候需要在插件maven-shade-plugin上做文章，主要用到的技术是ResourceTransformers

主要看下pom文件

<build>
<pluginManagement>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>2.3.1</version>
<configuration>
<source>1.7</source>
<target>1.7</target>
</configuration>
</plugin>
</plugins>
</pluginManagement>
<plugins>
<plugin>
97<groupId>org.apache.maven.plugins</groupId>
98<artifactId>maven-shade-plugin</artifactId>
<!--主要使用了ResourceTransformers做Aggregating[code]classes/resources

fromseveralartifactsintoonejar-->

125</transformer>
126</transformers>
127</configuration>
128</execution>
129</executions>
130</plugin>

</plugins>
</build>
</project>[/code]

3、一般的，如果是spring工程，打成可执行包的话在读取xml文件时会报错，这个时候需要在mvn中做些处理，生成一个runnable的jar，直接用mvn添加一些选项。这里其实也是使用了resoucetransform

<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>[b]maven-shade-plugin[/b]</artifactId>
<version>1.7</version>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>shade</goal>
</goals>
<configuration>
<finalName>pc-guess-like-fsf-app</finalName>//1、可执行jar包名字
<shadedArtifactAttached>true</shadedArtifactAttached>
<shadedClassifierName>jar-with-dependencies</shadedClassifierName>
<transformers>
<transformerimplementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
<mainClass>com.feiniu.recom.soa.consumer.pcGuessLike.FsfTest</mainClass>//2、这里是可执行jar包主类名字
</transformer>

<transformerimplementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
<resource>META-INF/spring.handlers</resource>
</transformer>
<transformerimplementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
<resource>META-INF/spring.schemas</resource>
</transformer>
<transformerimplementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
<resource>META-INF/spring.tooling</resource>
</transformer>
</transformers>
</configuration>

</execution>

</executions>
</plugin>
