deploy springboot to tomcat

　　　　1 在 Eclipse 中建立新的web项目【ABC】，之后转成Maven项目。

2 创建 class Application

3 修改POM

4 修改web.xml

5 export 成 WAR 到Tomcat 的 workapps里

　　　　 6 运行tomcat, 并在浏览器中查看。

Application.class

package demo;

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.EnableAutoConfiguration;

import org.springframework.boot.builder.SpringApplicationBuilder;

import org.springframework.boot.context.web.SpringBootServletInitializer;

import org.springframework.context.annotation.ComponentScan;

import org.springframework.context.annotation.Configuration;

import org.springframework.web.bind.annotation.PathVariable;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.RestController;

@Configuration

@ComponentScan

@EnableAutoConfiguration

public class Application extends SpringBootServletInitializer {

    private static Class<Application> applicationClass = Application.class;

    @Override

    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {

        return application.sources(applicationClass);

    }

    public static void main(String[] args) {

        SpringApplication.run(applicationClass, args);

    }

}

@RestController

class GreetingController {

    @RequestMapping("/hello/{name}")

    String hello(@PathVariable String name) {

        return "Hello, " + name + "!";

    }

}

备注：

spring-boot-starter-parent [Maven的用户可以通过继承spring-boot-starter-parent项目来获得一些合理的默认配置]
spring-boot-legacy [支持旧的遗留的 ]
spring-boot-starter-thymeleaf [parse html]
spring-boot-maven-plugin [Java -jar命令来启动jar包,打的包里面才会有maven依赖的jar包和spring boot的启动类]
maven-surefire-plugin [surefire 插件用来在maven构建生命周期的test phase执行一个应用的单元测试]
org.webjars [WebJars能使Maven的依赖管理支持OSS的JavaScript库/CSS库，比如jQuery、Bootstrap等]
spring-boot-devtools [spring-boot-devtools模块可以包含在任何项目中，它可以节省大量的时间] https://blog.csdn.net/isea533/article/details/70495714
