eclipse中创建springboot demo

1创建一个maven工程

2编辑pom.xml

</project>

3 编制Application.java

package com.springboot.test.stringbootDemo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;

//@SpringBootApplication  //该方式在此配置中不好使,需使用下面三个组件
@Configuration
@ComponentScan
@EnableAutoConfiguration
public class Application {

    public static void main(String[] args) {
        // TODO Auto-generated method stub

        SpringApplication.run(Application.class, args);
    }
}

4 编制Example.java

package com.springboot.test.stringbootDemo;

import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@EnableAutoConfiguration
public class Example {

    @RequestMapping("/")
    String home(){
        return "hello world";
    }

    @RequestMapping("/haha/{myName}")
    String index(@PathVariable String myName){
        return "hello ... + " + myName+"!!!";
    }
}

5 选中项目 maven-update

6 选中项目 右键- run as -Java Application—控制台打印springboot启动日志
7 浏览器 输入 localhost:8080 出现
