MAVEN Package Spring Project

The Springframework control is used in the program (mainly to operate the database with mybatis-spring).

Using MAVEN to manage the build of your project, you now need to build a jar package that contains all the dependent jar packages and can be run using Java-jar [filename] at the command line.

1. Maven-assembly-plugin

At the very beginning, try using the Maven-assembly-plugin plugin, which is configured as follows:

<build> <plugins> <plugin> <groupid>org.apache.maven.plugins</ Groupid> <artifactId>maven-assembly-plugin</artifactId> <version>2.4</version> <configuration> <descriptorRefs> &lt                    ;d escriptorref>jar-with-dependencies</descriptorref> </descriptorRefs> <archive> <manifest> &LT;MAINCLASS&GT;MAIN&LT;/MAINCLASS&G                        T </manifest> </archive> </configuration> <executions&                    Gt <execution> <id>make-assembly</id> <phase>package&lt                        ;/phase> <goals> <goal>single</goal> </goals> </execution> </executions> </plugin&gt        ; </plugins> </build>

However, after the command line was packaged with the MVN Package command, after running Java-jar, the error is as follows:

 for namespace [http://Www.springframework.org/schema/context] class path resource [Javaprojectapplicationcontext.xml]

Google for a while, some people on the internet said this is a bug Assembly-plugin plugin, because it in the third party packaging is, for Meta-inf under the Spring.handlers,spring.schemas and so on several files with the same name covered.

It is recommended to use the Maven-shade-plugin plugin.

2.maven-shade-plugin Plug-in

The shade plugin can import all dependent packages into the final executable jar package. Depending on the content on the Web, the POM is set up as follows:

<build> <plugins> <plugin> <groupid>org.apache.maven.plugins</groupi D> <artifactId>maven-shade-plugin</artifactId> <version>1.4</version> <executions> <execution> <phase>pack                      Age</phase> <goals> <goal>shade</goal>                              </goals> <configuration> <transformers> <Transformer Implementation="Org.apache.maven.plugins.shade.resource.ManifestResourceTransformer"> <mainClass>com.defonds.RsaEncryptor</mainClass> </transformer> <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> </transformers> </configuration> </execution> </executions> </plugin> </plugins> </build&gt ;

However, after the implementation of the error, as follows:

inch " Main "  for Manifest Main attributes

After the lookup, the reason is that some of the packages are repeated references, and after packing some more *. SF and other files, resulting in an error.

Solution, add the following code to the Pom.xml file:

<configuration>    <filters>      <filter>        <artifact>*:* </artifact>        < excludes>          <exclude>meta-inf/*. Sf</exclude>          <exclude>meta-inf/*. Dsa</exclude>          <exclude>meta-inf/*. rsa</exclude>        </excludes>      </filter>    </filters>  </configuration >  

MVN CLEAN;MVN package;  Java-jar ... After that, everything works fine.

Tossing a lot of day, and finally moving forward asynchronously, mark.
