maven生成可执行jar包题总结

（1）依赖jar包未打入到同一个jar文件中可以通过使用maven-shade-plugin插件解决这个问题。

 <plugin>

        <groupId>org.apache.maven.plugins</groupId>

        <artifactId>maven-shade-plugin</artifactId>

        <version>2.3</version>

        <executions>

          <execution>

            <phase>package</phase>

            <goals>

              <goal>shade</goal>

            </goals>

            <configuration>

              <transformers>

                <transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResource                                       Transformer">

                   <!-- 程序入口类 -->

                   <mainClass>com.xxxx.xxx.ServerStartup</mainClass>

                </transformer>

                            <transformer  

                                implementation="org.apache.maven.plugins.shade.resource.AppendingTran                                                                  sformer">  

                                <resource>META-INF/spring.handlers</resource>  

                            </transformer>  

                            <transformer  

                                implementation="org.apache.maven.plugins.shade.resource.AppendingTran                                                                              sformer">  

                                <resource>META-INF/spring.schemas</resource>  

                            </transformer>

              </transformers>

            </configuration>

          </execution>

        </executions>

      </plugin>

（2） 再打jar包过程中出现了java代码对jdk的版本有要求时，可以采用以下配置方式，对jdk的版本进行配置。

<plugin>

                <groupId>org.apache.maven.plugins</groupId>

                 <artifactId>maven-compiler-plugin</artifactId>

                <configuration>

                    <source>1.7</source>

                    <target>1.7</target>

                    <encoding>UTF-8</encoding>

                </configuration>

     </plugin>

（3）将java代码所涉及到资源文件（如dao层下面的xml统一打入jar包中），可以采用如下插件。

 <plugin>

            <artifactId>maven-resources-plugin</artifactId>

            <version>2.4</version>

            <executions>

                <execution>

                    <id>copy-xmls</id>

                    <phase>process-sources</phase>

                    <goals>

                        <goal>copy-resources</goal>

                    </goals>

                    <configuration>

                        <outputDirectory>${basedir}/target/classes</outputDirectory>

                        <resources>

                            <resource>

                                <directory>${basedir}/src/main/java</directory>

                                <includes>

                                    <include>**/*.xml</include>

                                </includes>

                            </resource>

                        </resources>

                    </configuration>

                </execution>

            </executions>

        </plugin>
