maven使用

1、指定main函數打包(這種打包依賴的jar會放到lib目錄下若是放到服務器啓動須要把lib也同時放入服務器)

<build>
		<plugins>
			<plugin>
				<groupId>org.apache.maven.plugins</groupId>
				<artifactId>maven-jar-plugin</artifactId>
				<configuration>
					<classesDirectory>target/classes/</classesDirectory>
					<archive>
						<manifest>
							<mainClass>com.sean.JerseyClient</mainClass>
							<useUniqueVersions>false</useUniqueVersions>
							<addClasspath>true</addClasspath>
							<classpathPrefix>lib/</classpathPrefix>
						</manifest>
						<manifestEntries>
							<Class-Path>.</Class-Path>
						</manifestEntries>
					</archive>
				</configuration>
			</plugin>
			<plugin>
				<groupId>org.apache.maven.plugins</groupId>
				<artifactId>maven-dependency-plugin</artifactId>
				<executions>
					<execution>
						<id>copy-dependencies</id>
						<phase>package</phase>
						<goals>
							<goal>copy-dependencies</goal>
						</goals>
						<configuration>
							<type>jar</type>
							<includeTypes>jar</includeTypes>
							<outputDirectory>
								${project.build.directory}/lib
							</outputDirectory>
						</configuration>
					</execution>
				</executions>
			</plugin>

		</plugins>
	</build>

jersey打war包放入tomcat啓動示例：https://jersey.github.io/documentation/latest/getting-started.html

2、springboot打入外部jar包

1. 外部jar包位置

2. pom.xml文件

   <?xml version="1.0" encoding="UTF-8"?>
    <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    		 xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

    	<parent>
    		<groupId>org.springframework.boot</groupId>
    		<artifactId>spring-boot-starter-parent</artifactId>
    		<version>2.1.5.RELEASE</version>
    		<relativePath/> <!-- lookup parent from repository -->

    	<build>

    		<plugins>
    			<plugin>

    				</configuration>
    			</plugin>
    		</plugins>
    	</build>
   
    </project>

3. 主要是添加下邊2個 systemPath、includeSystemScope

   <dependency>
    			<groupId>com.dameng</groupId>
    			<artifactId>DmJdbcDriver</artifactId>
    			<version>1</version>
    			<scope>system</scope>
    			<systemPath>
    				${basedir}/lib/DmJdbcDriver.jar
    			</systemPath>
    		</dependency>
   
   
    		<plugins>
    			<plugin>
    				<groupId>org.springframework.boot</groupId>
    				<artifactId>spring-boot-maven-plugin</artifactId>
    				<executions>
    					<execution>
    						<goals>
    							<goal>repackage</goal>
    						</goals>
    					</execution>
    				</executions>
    				<configuration>
    					<includeSystemScope>true</includeSystemScope>
    				</configuration>
    			</plugin>
    		</plugins>
