spring boot 初始化

准备工具：

1.eclipse

2.maven.

 

创建一个maven project

a.打开pom.xml.

加入需要的依赖:

 

<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>top.codefree.springboot</groupId>
<artifactId>codefree-springboot</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>jar</packaging>
<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>
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
</project>

然后就是创建自己的测试application, 

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
@SpringBootApplication
public class HelloApplication {

@RequestMapping(value = "hello")
@ResponseBody
public String hello() {

return "hello spring boot";

}

public static void main(String[] args) {

SpringApplication.run(HelloApplication.class, args);

}

}

注意：

@ResponseBody(让输出以json格式输出)

@SpringBootApplication(等价于@Configuration, @EnableAutoConfiguration, @ComponentScan)

启动：

run as --> java Application

 

在浏览器输入： localhost:8080/hello
