spring boot packaged as war package, introduction of external jar package

1, a new directory in the jar src / main / resource, the outer bag on the directory jar

 

 

 2, adding a dependency in pom.xml

 

 

 groupId, artifactId, version can easily write

<dependency>
            <groupId>com.huawei</groupId>
            <artifactId>gsjdbc4</artifactId>
            <version>1.0</version>
            <scope>system</scope>
            <systemPath>${basedir}/src/main/resources/jar/gsjdbc4.jar</systemPath>
        </dependency>
        <dependency>
            <groupId>com.huawei</groupId>
            <artifactId>gsjdbc200</artifactId>
            <version>1.0</version>
            <scope>system</scope>
            <systemPath>${basedir}/src/main/resources/jar/gsjdbc200.jar</systemPath>
        </dependency>

At this, local access is not a problem to start the project, but the packaging, then it will error, the following steps

3, pom.xml increased plugin configuration

 

 

 

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

然后再打包即可

4,遇到的问题

打包时报错: Error assembling WAR: webxml attribute is required (or pre-existing WEB-INF/web.xml if executing in update mode)

原因: maven 插件 maven-war-plugin 中 Servlet 版本太低，要求必须要有web.xml文件才行

解决方法: 把plugin配置里面的<version>2.4</version>去掉,再次打包即可
