建议你这样试试看：

1. 在 Eclipse 中新一个 maven 工程。

2. 修改 pom.xml 文件添加如下内容：

3. <parent>
           <groupId>org.springframework.boot</groupId>
           <artifactId>spring-boot-starter-parent</artifactId>
           <version>1.5.9.RELEASE</version>
       </parent>
   
       <dependencies>
           
           <dependency>
               <groupId>org.springframework.boot</groupId>
               <artifactId>spring-boot-starter-web</artifactId>
           </dependency>
           
           <dependency>
           	<groupId>org.springframework.boot</groupId>
           	<artifactId>spring-boot-starter-actuator</artifactId>
           </dependency>
           
           <dependency>
           	<groupId>org.springframework.boot</groupId>
           	<artifactId>spring-boot-starter-test</artifactId>
           	<scope>test</scope>
           </dependency>
           
       </dependencies>
   
       <properties>
           <java.version>1.8</java.version>
       </properties>
   
   	<profiles>
   		<profile>
   			<id>jdk-1.8</id>
   			<activation>
   				<activeByDefault>true</activeByDefault>
   				<jdk>1.8</jdk>
   			</activation>
   			<properties>
   				<maven.compiler.source>1.8</maven.compiler.source>
   				<maven.compiler.target>1.8</maven.compiler.target>
   				<maven.compiler.compilerVersion>1.8</maven.compiler.compilerVersion>
   			</properties>
   		</profile>
   	</profiles>
   
   	<build>
           <plugins>
               <plugin>
                   <groupId>org.springframework.boot</groupId>
                   <artifactId>spring-boot-maven-plugin</artifactId>
               </plugin>
           </plugins>
       </build>

4. 添加 Application 类：

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class Application {

	public static void main(String[] args) {
		
		SpringApplication.run(Application.class, args);
	}
}

5. 添加 HelloController 类：

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("/hello")
public class HelloController {

	@RequestMapping("/welcome")
	public String welcome() {
		return "Hello World!";
	}
}

然后运行。
