SSM二:spring boot最小可运行系统

springboot本身已经封装得比较好了,所以使用它的代码也较简单:

该项目可以用于一些提供接口的情况。

两个类,一个pom.xml配置:

一个启动类:

package net.highesoft.ssm;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;

@Configuration 
@ComponentScan 
@EnableAutoConfiguration 
public class Application { 
    public static void main(String[] args) { 
        SpringApplication.run(Application.class); 
    } 
}
一个Controller:

package net.highesoft.ssm.controller;

import java.util.HashMap;
import java.util.Map;

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

@RestController
public class TestController {

	@RequestMapping("/")
	public Map<String,String> home() {
		Map<String,String> map=new HashMap<>();
		map.put("key", "value");
		return map;
	}

}


pom.xml

            </plugin>
        </plugins>
    </build>
</project>

启动动Application.java后,可以浏览器输入http://localhost:8080 看到效果。
