摘要:
- 无论是从IDEA还是其他的SDS开发工具亦或是https://start.spring.io/ 进行解压,我们都会得到同样的一个
pom.xml
文件
xml <?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"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.1.6.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent> <groupId>com.github.dqqzj</groupId> <artifactId>springboot</artifactId> <version>0.0.1-SNAPSHOT</version> <name>springboot</name> <packaging>jar</packaging> <description>Demo project for Spring Boot</description> <properties> <java.version>1.8</java.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project>
parent
标签的含义
- 找到本地仓库的
spring-boot-starter-parent
坐标
xml <?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"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-dependencies</artifactId> <version>2.1.6.RELEASE</version> <relativePath>../../spring-boot-dependencies</relativePath> </parent> <!-- 省略无关代码...... --> <build> <!-- 省略无关代码...... --> <pluginManagement> <plugins> <!-- 省略无关代码...... --> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> <executions> <execution> <id>repackage</id> <goals> <goal>repackage</goal> </goals> </execution> </executions> <configuration> <mainClass>${start-class}</mainClass> </configuration> </plugin> <!-- 省略无关代码...... --> </plugins> </pluginManagement> </build> </project>
关注点
xml <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-dependencies</artifactId> <version>2.1.6.RELEASE</version> <relativePath>../../spring-boot-dependencies</relativePath> </parent>
说明我们的工程可以进行改造进行替换掉原来工程的parent
标签.
xml <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> <executions> <execution> <id>repackage</id> <goals> <goal>repackage</goal> </goals> </execution> </executions> <configuration> <mainClass>${start-class}</mainClass> </configuration> </plugin>
repackage
必须要有否则打jar
包时候无法正常启动.
在配置文件加上repackage
即可
<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>
IDEA
自带maven
工具
mvnw
是基于linux
的shell
脚本命令
mvnw.cmd
是基于windows
的脚本命令
.mvn
包含了 maven
下载路径以及版本等信息
也就是说我们完全不用自己下载maven
而是可以直接使用IDEA
给我们提供的工具即可,只不过通常不会这么做。
repackage
的作用
正常情况下打包会生成springboot-0.0.1-SNAPSHOT.jar.original
,springboot-0.0.1-SNAPSHOT.jar
这样的2个文件,而repackage
的作用就是将springboot-0.0.1-SNAPSHOT.jar.original
重新打包为我们可以执行的springboot-0.0.1-SNAPSHOT.jar
