1, 继承父工程, 用 parent 标签, 如下:
pom.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>
- <groupId>com.edu.spring</groupId>
- <artifactId>springboot</artifactId>
- <version>1.0.0</version>
- <packaging>jar</packaging>
- <name>springboot</name>
- <!-- FIXME change it to the project's website -->
- <url>http://www.example.com</url>
- <parent>
- <groupId>org.springframework.boot</groupId>
- <artifactId>spring-boot-starter-parent</artifactId>
- <version>2.0.4.RELEASE</version>
- <relativePath/>
- </parent>
- <properties>
- <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
- <maven.compiler.source>1.8</maven.compiler.source>
- <maven.compiler.target>1.8</maven.compiler.target>
- </properties>
- <dependencies>
- <dependency>
- <groupId>org.springframework.boot</groupId>
- <artifactId>spring-boot-starter</artifactId>
- </dependency>
- </dependencies>
- </project>
- View Code
App.java
- package com.edu.spring.springboot;
- import org.springframework.boot.SpringApplication;
- import org.springframework.boot.autoconfigure.SpringBootApplication;
- import org.springframework.context.ConfigurableApplicationContext;
- import org.springframework.context.annotation.Bean;
- @SpringBootApplication
- public class App
- {
- @Bean
- Runnable createRunnable(){
- return () -> {System.out.println("spring boot is run");};
- }
- public static void main( String[] args )
- {
- ConfigurableApplicationContext context=SpringApplication.run(App.class, args);
- context.getBean(Runnable.class).run();
- }
- }

运行结果如下:
2, 使用 dependencyManagement 标签, 如下:
pom.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>
- <groupId>com.edu.spring</groupId>
- <artifactId>springboot</artifactId>
- <version>1.0.0</version>
- <packaging>jar</packaging>
- <name>springboot</name>
- <!-- FIXME change it to the project's website -->
- <url>http://www.example.com</url>
- <dependencyManagement>
- <dependencies>
- <dependency>
- <groupId>org.springframework.boot</groupId>
- <artifactId>spring-boot-dependencies</artifactId>
- <version>2.1.6.RELEASE</version>
- <scope>import</scope>
- <type>pom</type>
- </dependency>
- </dependencies>
- </dependencyManagement>
- <properties>
- <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
- <maven.compiler.source>1.8</maven.compiler.source>
- <maven.compiler.target>1.8</maven.compiler.target>
- </properties>
- <dependencies>
- <dependency>
- <groupId>org.springframework.boot</groupId>
- <artifactId>spring-boot-starter</artifactId>
- </dependency>
- </dependencies>
- </project>
- View Code
运行 App.java, 结果如下:
可以看到, 两种方式, 都可以正常运行.
