eclipse中创建springboot demo

1创建一个maven工程







2编辑pom.xml

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+"!!!";
}
}
