Springboot的优点和实现

一 优点

  1.创建独立的Spring应用程序

  2.嵌入式的Tomcat,不需要部署war包

  3.简化Maven配置

  4.自动配置Spring

  5.提供生产就绪型功能,如指标,健康检查,和外部配置

  6.开箱即用,没有代码生成,也无需XML配置

二 代码实现

    1.环境要求

    JDK1.7及以上,Spring framework 4.1.5及以上

  2.pom.xml

  

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

            <artifactId>spring-boot-starter-web</artifactId>

        <!-- 引入freeMarker的依赖包. -->
        <dependency>

            <artifactId>spring-boot-starter-freemarker</artifactId>
        </dependency>
    </dependencies>
</project>

  3.Controller

package com.lf.controller;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@EnableAutoConfiguration//此注释自动载入应用程序所需的所有Bean
@RestController//@RestController = @Controller + 每个方法都加上@RequestBody注解
public class HelleController {
    
    @RequestMapping("hello")
    public String hello(){
        return "success";
    }
    
    public static void main(String[] args) {
        SpringApplication.run(HelleController.class, args);
    }
}
