听说spring boot零配置,挺好用,我也来试用下。

1.创建Maven项目,配置pom.xml(部分依赖包在此demo中没有用到,此demo只用到spring-boot-starter-parent、spring-boot-starter-web,其他的会在往后的实际项目中用到,所以也贴了出来,大家各取所需)

2.编码Controller、Run

@RestController //@RestController相当于@Controller+@ResponseBody
@RequestMapping("/test")
public class HelloController {
	
	@RequestMapping("/hello")
        public String getHello() {
                return "Hello Spring Boot .....";
        }
	

}

 

//@SpringBootApplication所在类的同级包以及下级包里的所有bean
@SpringBootApplication
@ServletComponentScan
// 使用@ServletComponentScan注解后,Servlet、Filter、Listener可以直接通过@WebServlet、@WebFilter、@WebListener注解自动注册
public class Run implements EmbeddedServletContainerCustomizer {

	// 修改访问的默认端口
	@Override
	public void customize(ConfigurableEmbeddedServletContainer container) {
		container.setPort(80);
	}

	public static void main(String[] args) {
		SpringApplication.run(Run.class, args);
	}

}

3.启动项目,进入Run.java,右键运行java application

4.打开浏览器访问:localhost/test/hello

好吧,真的很简单,sping和web的配置都不用。关键是部署到Linux要怎么办?

也很简单,打包后是一个可执行的jar包,将这jar包放到Linux服务器上,通过命令:

java -jar project.jar

即可启动项目,无需tomcat容器。

简单归简单,但也有问题。平常接触的项目基本都会在web.xml配置过滤器,监听器,在mvc上配置拦截器等等,而spring boot没有这些配置文件,那这些配置,在代码怎样实现?继续深入……
