篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Spring Boot中配置文件application.properties里面配置项的引用相关的知识，希望对你有一定的参考价值。

方法1:Environment

    @Autowired//import org.springframework.core.env.Environment;
    private Environment environment;

    @org.junit.Test
    public void readConfigFile(){
        System.out.println(environment.getProperty("spring.datasource.driverClassName"));
    }

控制台打印:

方法2：绑定对象bean调用

1、在application.properties或者application.yml里面添加我们的配置项：

2、创建一个配置类（该类和我们上面配置项的属性一一对应）：

import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;

@Component
@ConfigurationProperties(prefix = "upload")
public class PropertiesConfig {
    private  int port;

    public int getPort() {
        return port;
    }

    public void setPort(int port) {
        this.port = port;
    }
}

3、在需要调用的地方自动装配上我们上面的类并按照下面的方式获得配置项的值：

@Controller
@RequestMapping("/update/send")
public class UpdateSendController extends BaseController {    
@Autowired
    private PropertiesConfig propertiesconfig;
    int port = propertiesconfig.getPort();
}
