1、安装springboot
1）首先检查jdk版本是1.8或更高版本。
java -version
2）jar依赖建议使用支持依赖管理功能的编译工具，这里使用maven建立工程
springboot是用maven3.2以及以上版本进行编译的
3）添加springboot依赖
典型的maven pom文件会集成自spring-boot-starter-parent工程并声明一个或多个starters
<1>典型场景
<?xml version="1.0" encoding="UTF-8"?> <projectxmlns="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.example</groupId> <artifactId>myproject</artifactId> <version>0.0.1-SNAPSHOT</version> <!-- Inherit defaults from Spring Boot --> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.0.1.RELEASE</version> </parent> <!-- Add typical dependencies for a web application --> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> </dependencies> <!-- Package as an executable jar --> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project> |
<2>如果不想使用 spring-boot-starter-parent，同时扔保持依赖管理的好处（非插件管理），可以通过使用 scope=import的依赖
<dependencyManagement> <dependencies> <!-- Override Spring Data release train provided by Spring Boot --> <dependency> <groupId>org.springframework.data</groupId> <artifactId>spring-data-releasetrain</artifactId> <version>Fowler-SR2</version> <type>pom</type> <scope>import</scope> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-dependencies</artifactId> <version>2.0.1.RELEASE</version> <type>pom</type> <scope>import</scope> </dependency> </dependencies> </dependencyManagement> |
4）使用maven插件可以将工程打包为可执行jar
<!-- Package as an executable jar --> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> |
5）查看工程依赖树
mvn dependency:tree
