SprintBoot HelloWorld工程的建立
方式1:
1.新建一个Maven jar工程,
pom.xml添加
<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.utopia</groupId> <artifactId>introduction</artifactId> <version>0.0.1-SNAPSHOT</version> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.4.0.RELEASE</version> </parent> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> </dependencies> </project>
新建一个类SampleController,包名随意
@Controller @EnableAutoConfiguration public class SampleController { @RequestMapping("/intro") @ResponseBody String home() { return "Hello World!"; } public static void main(String[] args) throws Exception { SpringApplication.run(SampleController.class, args); } }
右键,run as java application,

方式2:
新建Maven war工程
pom.xml
<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>1.5.2.RELEASE</version> </parent> <groupId>com.utopia</groupId> <artifactId>hello</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>war</packaging> <dependencies> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>4.3.7.RELEASE</version> </dependency> <!-- 连接池 --> <dependency> <groupId>com.jolbox</groupId> <artifactId>bonecp-spring</artifactId> <version>0.8.0.RELEASE</version> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> </dependencies> <build> <finalName>${project.artifactId}</finalName> <plugins> <!-- 资源文件拷贝插件 --> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-resources-plugin</artifactId> <configuration> <encoding>UTF-8</encoding> </configuration> </plugin> <!-- java编译插件 --> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <configuration> <source>1.7</source> <target>1.7</target> <encoding>UTF-8</encoding> </configuration> </plugin> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> <pluginManagement> <plugins> <!-- 配置Tomcat插件 --> <plugin> <groupId>org.apache.tomcat.maven</groupId> <artifactId>tomcat7-maven-plugin</artifactId> <version>2.2</version> </plugin> </plugins> </pluginManagement> </build> </project>
新建类HelloApplication
@Controller @SpringBootApplication @Configuration public class HelloApplication { @RequestMapping("gotcha") @ResponseBody public String hello() { return "hello world!legionaire!"; } public static void main(String[] args) { SpringApplication.run(HelloApplication.class, args); } }
