SpringBoot入门

入门demo

1. eclispe 创建一个基本的maven项目
2. 配置pom.xml  引入spring boot所需要的jar包 见下文
3. 新建pojo controller 
4. 创建Application.java  通过main方法启动项目

@SpringBootApplication
@EnableAutoConfiguration
public class Application {

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

@Configuration
@ImportResource("classpath:/application-context.xml")
class XmlImportConfiguration {
}

application-context.xml文件：

<?xml version="1.0" encoding="UTF-8"?>

       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

                    ignore-unresolvable="true"
                    system-properties-mode="ENVIRONMENT"
                    location="classpath:application.properties"/>
</beans>
