公司要對springboot項目依賴的jar包進行升級,但是遇到一個問題,項目打包之后,沒辦法看到他里面依賴的jar包,版本到底是不是升上去了,沒辦法看到,下面通過本文給大家分享Springboot項目打包如何將依賴的jar包輸出到指定目錄,感興趣的朋友一起看看吧

場景

公司要對springboot項目依賴的jar包進行升級，但是遇到一個問題，項目打包之后，沒辦法看到他里面依賴的jar包，版本到底是不是升上去了，沒辦法看到。

下面是項目打的jar包

我們通過反編譯工具jdgui，來看一下jar包文件內容，我們發(fā)現里面根本沒有看到依賴的jar包

既然看不到依賴的jar包，那么就沒辦法確定，jar包版本是否升級成功，那應該怎么辦呢？

解決辦法

maven有一個辦法，就是可以將依賴的jar包輸出的指定的目錄。具體配置如下：

<?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">

	</dependencyManagement>
    <properties>

	</properties>
    <dependencies>
        <!-- spring boot -->
        <dependency>
            .....
        </dependency>
	</dependencies>
    <build>
    	<resources>
			<resource>

				<filtering>true</filtering>
				<excludes>
                    <exclude>static/**</exclude>
                </excludes>

                <filtering>false</filtering>
                <includes>
                    <include>static/**</include>
                </includes>
			</resource>
		</resources>
        <plugins>
			<plugin>
		      <groupId>org.springframework.boot</groupId>
		      <artifactId>spring-boot-maven-plugin</artifactId>

		      </configuration>
		      <executions>
		        <execution>
		          <goals>

		      </executions>
		    </plugin>
			<plugin>

						<configuration>
							<!--target/lib是依賴jar包的輸出目錄，根據自己喜好配置-->
							<outputDirectory>target/lib</outputDirectory>
							<excludeTransitive>false</excludeTransitive>
							<stripVersion>false</stripVersion>
							<includeScope>runtime</includeScope>
						</configuration>
					</execution>
				</executions>
			</plugin>
		</plugins>
    </build>
</project>

重要的事再說一遍，其實核心就是這一句配置

<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>
							<!--target/lib是依賴jar包的輸出目錄，根據自己喜好配置-->
							<outputDirectory>target/lib</outputDirectory>
							<excludeTransitive>false</excludeTransitive>
							<stripVersion>false</stripVersion>
							<includeScope>runtime</includeScope>
						</configuration>
					</execution>
				</executions>
			</plugin>

我們再打包一下看看效果：
