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
2、修改工程目录,添加源文件夹后目录如下:
3、修改pom.xml文件如下:
按 Ctrl+C 复制代码 按 Ctrl+C 复制代码4、编辑JAVA代码新建APP.class
按 Ctrl+C 复制代码 按 Ctrl+C 复制代码运行此代码 服务端口默认8080 访问localhost:8080/h 展示Hello
localhost:8080/w 展示World
OK!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
---------------风格线---------------------
新建RestController风格的Controller
新建UserController
按 Ctrl+C 复制代码 按 Ctrl+C 复制代码需修改App.java
按 Ctrl+C 复制代码 按 Ctrl+C 复制代码运行App.java 访问 http://localhost:8080/user/12
新建其他Controller
按 Ctrl+C 复制代码 按 Ctrl+C 复制代码重启程序 访问http://localhost:8080/file/name
======================================================
修改默认端口
一、
package com.lgp.SpringBoot; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.boot.context.embedded.ConfigurableEmbeddedServletContainer; import org.springframework.boot.context.embedded.EmbeddedServletContainerCustomizer; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; @RestController @SpringBootApplication public class MainApplication implements EmbeddedServletContainerCustomizer{ @Override public void customize(ConfigurableEmbeddedServletContainer container) { container.setPort(8011); } public static void main(String[] args) { // SpringApplication.run(MainApplication.class, args); SpringApplication.run(FileController.class, args); } @RequestMapping("/main") public String testPort(){ return "Hello 端口8011......"; } }二、
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; } }修改为8011
