spring boot 通过bean获取 application.properties 中配置

/**

@Component
@ConfigurationProperties(prefix = "data.source")
public class BackDataSourcesProperties {

    private String url;

    private String driver;

    private String username;

    private String password;

    public String getUrl() {

        return url;
    }

    public void setUrl(String url) {

        this.url = url;
    }

    public String getDriver() {

        return driver;
    }

    public void setDriver(String driver) {

        this.driver = driver;
    }

    public String getUsername() {

        return username;
    }

    public void setUsername(String username) {

        this.username = username;
    }

    public String getPassword() {

        return password;
    }

    public void setPassword(String password) {

        this.password = password;
    }

}

application.properties：

data.source.driver=org.apache.hive.jdbc.HiveDriver
data.source.url=jdbc:mysql://192.168.1.1128:10011/lierbai
data.source.username=root
data.source.password=123456
