SpringBoot實戰開發(一)——HelloWord實現

1、建立Maven project專案
點next,然後選擇quickstart模板
以上完成Maven專案的建立
2、引入Pom依賴
<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.scw.clear</groupId> <artifactId>sc-clear</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>jar</packaging> <!-- spring boot 父節點依賴,引入這個之後相關的引入就不需要新增version配置,spring boot會自動選擇最合適的版本進行新增。 --> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.5.9.RELEASE</version> <relativePath /> </parent> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <!-- 指定一下jdk的版本 ,這裡我們使用jdk 1.8 ,預設是1.6 --> <java.version>1.8</java.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> <!--<version></version>由於我們在上面指定了 parent(spring boot) --> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> <!--<version></version>由於我們在上面指定了 parent(spring boot) --> </dependency> <!-- spring boot devtools 熱部署 依賴包. --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-devtools</artifactId> <optional>true</optional> <scope>true</scope> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> <!-- 跳過單元測試 --> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-surefire-plugin</artifactId> <configuration> <skipTests>true</skipTests> </configuration> </plugin> </plugins> </build> </project>
3、建立啟動類
package com.sc.clear; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; @SpringBootApplication(scanBasePackages="com.sc.clear") public class ScApplication { public static void main(String[] args) { //專案入口 SpringApplication.run(ScApplication.class, args); } }
4、建立HelloController,測試HelloWorld
以上完成所有操作。通過啟動類的main方法右鍵Run As=====》Java Application進行啟動專案。通過http://localhost:8080/hello進行測試。package com.sc.clear.controller; import java.util.List; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.bind.annotation.RestController; @RestController public class DemoController { @RequestMapping(value="/hello",method=RequestMethod.GET) public String helloWorld() { return "Hello World"; } }
