SpringBoot快速入门
springboot的宗旨是习惯大于配置,所以spring里面大量使用了默认的配置来简化spring的配置。spring Boot的主要优点:
- 为所有Spring开发者更快的入门
- 开箱即用,提供各种默认配置来简化项目配置
- 内嵌式容器简化Web项目
- 没有冗余代码生成和XML配置的要求
快速搭建一个springboot helloworld
开发环境java8,maven,idea
1.修改pom文件
<!-- Inherit defaults from Spring Boot -->
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.4.0.RELEASE</version>
</parent>
<!-- Add typical dependencies for a web application -->
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
</dependencies>
<!-- Package as an executable jar -->
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
2.编写helloworld
@RestController
@EnableAutoConfiguration
public class HelloWorld {
@RequestMapping("/hello")
public String index() {
return "Hello World";
}
public static void main(String[] args) throws Exception {
SpringApplication.run(HelloWorld.class, args);
}
}
