IDE中创建maven项目

最简pom依赖

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.5.8.RELEASE</version>
</parent>
<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
</dependencies>

示例代码 hello/SampleController.java

package hello;
import org.springframework.boot.*;
import org.springframework.boot.autoconfigure.*;
import org.springframework.stereotype.*;
import org.springframework.web.bind.annotation.*;

@Controller
@EnableAutoConfiguration
public class SampleController {

    @RequestMapping("/sayHello")
    @ResponseBody
    String home() {
        return "Hello World!";
    }

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

测试

1. 运行main方法
2. 浏览器访问: localhost:8080/sayHello
3. 页面会显示Hello World!
4. 学习Spring Boot的Hello World程序已成功carry

打成可执行JAR

如上的代码在IDE中执行，毫无问题
但是怎么把代码部署到服务器上去呢？

需要在pom中增加如下的插件

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>

            <plugin> 
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId> 
                <version>3.3</version>
                <configuration> 
                    <encoding>UTF-8</encoding> 
                    <source>1.7</source>
                    <target>1.7</target>
                </configuration> 
            </plugin>
        </plugins>
    </build>

   mvn clean package打成可执行jar后，放到服务器上
   java -jar springbootDemo.jar
   观察启动日志，如果没报错
   在浏览器访问http://${ip}:${port}/tt如果返回Hello World!说明大功告成
