Spring Boot入门===Hello World

昨天无意间看到Spring Boot ,今天又了解了一下，试着写一个Hello World! 今天看了半天，最后还是要用Maven最方便！以下：

一、工具

JDK1.7

Eclipse

Maven

这里Eclipse集成Maven的这一步就省了！

二、编码

新建Maven Project 命名为：SpringBoot 选项如图

package com.lgp.SpringBoot;

import java.util.concurrent.TimeUnit;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.context.embedded.EmbeddedServletContainerFactory;
import org.springframework.boot.context.embedded.tomcat.TomcatEmbeddedServletContainerFactory;
import org.springframework.context.annotation.Bean;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@EnableAutoConfiguration
public class App
{
@RequestMapping("/h")
public String home() {
return "Hello";
}

@RequestMapping("/w")
public String word() {
return "World";
}

public static void main( String[] args )
{
System.out.println( "Hello World ! App!" );
//SpringApplication.run(App.class, args);
SpringApplication.run(UserController.class, args);
}

@Bean
public EmbeddedServletContainerFactory servletFactory(){
TomcatEmbeddedServletContainerFactory tomcatFactory =
new TomcatEmbeddedServletContainerFactory();
tomcatFactory.setPort(8011);
tomcatFactory.setSessionTimeout(10,TimeUnit.SECONDS);
return tomcatFactory;

}
}

App.java
修改为8011
