本文介绍如何将无法通过Maven获取的外部JAR（如Oracle JDBC驱动）打包进WAR或JAR文件中，包括修改pom.xml配置、添加资源路径等步骤。

#1问题描述
由于需要使用外部jar，无法从maven上下载引用，如Oracle或SQL Server的JDBC驱动包
在直接打包的时候无法添加到war或jar，则需要方法将外部jar打包到war或jar

#2解决办法
*1）在根目录下创建lib文件夹，并将驱动jar放到里面引用使用
这里写图片描述
*2）在pom.xml中添加外部jar的引用

		<dependency>
	        <groupId>ojdbc</groupId>
	        <artifactId>ojdbc</artifactId>
	        <version>7</version>
	        <scope>system</scope>
	        <systemPath>${project.basedir}/lib/ojdbc7.jar</systemPath>
	    </dependency>
	    <dependency>
	        <groupId>sqljdbc</groupId>
	        <artifactId>sqljdbc</artifactId>
	        <version>42</version>
	        <scope>system</scope>
	        <systemPath>${project.basedir}/lib/sqljdbc42.jar</systemPath>
	    </dependency>

*3）在pom.xml上添加插件支持将外部jar打包到war

		<plugin>
	        <groupId>org.apache.maven.plugins</groupId>
	        <artifactId>maven-war-plugin</artifactId>
	        <configuration>
	            <webResources>
	                <resource>
	                    <directory>lib</directory>
	                    <targetPath>WEB-INF/lib/</targetPath>
	                    <includes>
	                        <include>**/*.jar</include>
	                    </includes>
	                </resource>
	            </webResources>
	            <failOnMissingWebXml>false</failOnMissingWebXml>
	        </configuration>
	    </plugin>

*4）在pom.xml上添加配置支持将外部jar打包到jar

		<resources>
			<resource>
				<directory>lib</directory>
				<targetPath>BOOT-INF/lib/</targetPath>
				<includes>
					<include>**/*.jar</include>
				</includes>
			</resource>
			<resource>
				<directory>src/main/resources</directory>
				<includes>
					<include>*.yml</include>
				</includes>
			</resource>
		</resources>

#3完整pom.xml参考
注意：打包成war的时候注释jar的配置，打包成jar的时候注释war的配置
