這篇文章給大家介紹springboot多模塊打包的記錄是怎樣的，內(nèi)容非常詳細(xì)，感興趣的小伙伴們可以參考借鑒，希望對(duì)大家能有所幫助。
項(xiàng)目結(jié)構(gòu)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"> <parent> <artifactId>demo</artifactId> <groupId>com.hs</groupId> <version>0.0.1-SNAPSHOT</version> </parent> <modelVersion>4.0.0</modelVersion> <artifactId>domain</artifactId> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-jpa</artifactId> </dependency> <dependency> <groupId>com.hs</groupId> <artifactId>common</artifactId> <version>0.0.1-SNAPSHOT</version> </dependency> </dependencies> </project>
common子項(xiàng)目（公共類項(xiàng)目）
<?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> <artifactId>demo</artifactId> <groupId>com.hs</groupId> <version>0.0.1-SNAPSHOT</version> </parent> <modelVersion>4.0.0</modelVersion> <artifactId>common</artifactId> </project>
下面開始測試，目前spring-boot-maven-plugin在父pom文件上，執(zhí)行后報(bào)錯(cuò)找不到main class文件：Failed to execute goal org.springframework.boot:spring-boot-maven-plugin:2.4.4:repackage (default) on project common: Execution default of goal org.springframework.boot:spring-boot-maven-plugin:2.4.4:repackage failed: Unable to find main class
按照提示，在父pom.xml中增加main class的配置
<plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> <configuration> <mainClass>com.hs.demo.DemoApplication</mainClass> <layout>ZIP</layout> </configuration> <executions> <execution> <goals> <goal>repackage</goal> </goals> </execution> </executions> </plugin>
這會(huì)報(bào)了4個(gè)錯(cuò)誤，都是報(bào)包不存在的
繼續(xù)測試，把spring-boot-maven-plugin放到主工程的pom中去
最終controller工程的pom.xml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"> <parent> <artifactId>demo</artifactId> <groupId>com.hs</groupId> <version>0.0.1-SNAPSHOT</version> </parent> <modelVersion>4.0.0</modelVersion> <artifactId>controller</artifactId> <packaging>jar</packaging> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> </dependency> <dependency> <groupId>com.hs</groupId> <artifactId>domain</artifactId> <version>0.0.1-SNAPSHOT</version> </dependency> <dependency> <groupId>com.hs</groupId> <artifactId>common</artifactId> <version>0.0.1-SNAPSHOT</version> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> <executions> <execution> <goals> <goal>repackage</goal> </goals> </execution> </executions> </plugin> </plugins> </build> </project>
繼續(xù)測試，打包成功，文件大小正常
這個(gè)repackage有什么用呢？去了試試，最終變成這樣
<build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build>
同樣也打包成功，只不過主工程的jar大小有點(diǎn)問題，只有4kb
看看官網(wǎng)對(duì)這個(gè)的解釋：https://docs.spring.io/spring-boot/docs/2.4.4/maven-plugin/reference/htmlsingle/#repackage-example-exclude-dependency
這個(gè)其實(shí)就是把所有依賴的jar包都打進(jìn)來。
