Maven项目生成可运行的jar包

使用eclipse的export导出可运行的项目时，配置文件默认为打包到resources中的。这样导致程序在eclipse中可以正常运行，但导出项目后，却因找不到配置文件导致项目不能运行。原来使用maven-shade-plugins就可以生成可执行的jar包。只需要在target目录下把生成的jar考出来执行java -jar <jar>即可。

1.首先把插件考入pom.xml中。参考:[https://blog.csdn.net/yukangmine/article/details/40042263][https_blog.csdn.net_yukangmine_article_details_40042263]

<plugin>
    				    <groupId>org.apache.maven.plugins</groupId>
    				<artifactId>maven-shade-plugin</artifactId>
    				<version>1.2.1</version>
    				<executions>
    					<execution>
    						<phase>package</phase>
    						<goals>
    							<goal>shade</goal>
    						</goals>
    						<configuration>
    							<transformers>
    								<transformer
    									implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
    									<mainClass>com.qdcan.rmi.service.RMIService</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>
    								<transformer
    									implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
    									<resource>META-INF/spring.tooling</resource>
    								</transformer>
    							</transformers>
    						</configuration>
    					</execution>
    				</executions>
    			</plugin>

2.如果同时引用了spring-context,spring-aop,spring-tx时，项目配置文件会相互覆盖，导致报Unable to locate Spring NamespaceHandler for XML schema错误。处理办法是将配置文件合并。参考:[https://blog.csdn.net/shuimuniao/article/details/80805308][https_blog.csdn.net_shuimuniao_article_details_80805308]

至此可以正确执行生成的jar包了。
