Spring boot 可以提升开发效率简化spring.xml配置文件首先是一个helloworld 小例子:
package web.app.test.boot; import java.util.concurrent.atomic.AtomicLong; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.EnableAutoConfiguration; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.ResponseBody; @Controller @EnableAutoConfiguration public class TestController { public final String temp = "Hello,%s"; public final AtomicLong a1 = new AtomicLong(); @RequestMapping("/test") @ResponseBody Animal home(String name){ return new Animal((int) a1.incrementAndGet(),String.format(temp, name)); } public static void main(String[] args) { SpringApplication.run(TestController.class, args); } }实体类就不往上写了 Animal 属性 id name
下面是maven pom.xml的配置
<parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.3.3.RELEASE</version> </parent> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> </dependencies>此时直接右键run as 就能跑了
启动成功可以用 http://localhost:8080/test?name=world 地址测试了;
PS:1、一定注意要是Maven的web项目(web.xml完全不用配置)
2、修改代码后一定要先停服务在启动。(好像也可以配置成修改代码后自动重启的,可以百度下)
3、也可参照官网http://projects.spring.io/spring-boot/
不忘初心,方得始终!
