springboot(1)快速搭建WEB环境

springboot

1、建立项目

建议使用spring-tool-suite来建立编辑springboot项目，该版本的Eclipse比普通版本的Eclipse添加了对springboot的插件支持。
创建本地maven项目，并编辑pom.xml文件，添加如下内容

2、创建springboot启动入口

package com.wxtx;

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

/**
 * springboot默认值扫描启动入口所在的包及其子包，可用过scanBasePackages参数指定扫描的包路径
 */
@SpringBootApplication(scanBasePackages="com")
public class TXSpringBootApplication {
	public static void main(String[] args) {
		SpringApplication.run(TXSpringBootApplication.class, args);
	}
}

3、创建Control控制器

package com.wxtx.action;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
public class TestAction {
	
	@ResponseBody
	@RequestMapping("/index")
	public String index() {
		return "hello world";
	}
}

4、启动项目

java运行TXSpringBootApplication类，打开浏览器访问http://127.0.0.1:8080/index即可。

注：springboot内置了tomcat，所以springboot web项目启动时，不需要使用tomcat server来启动，直接java application运行即可。
