基于SSM的博客系统开发

Spring Boot 动态加载jar文件

接口实现：

package org.bc.device;

public interface IDeviceHandler {
    String start();
    String stop();
}

实现类：
package org.bc.device;

public class MqttDevice implements IDeviceHandler{
@Override
public String start() {
return “MqttDevice…start…”;
}
@Override
public String stop() {
return “MqttDevice…stop…”;
}
}
实现类：

package org.bc.device;

public class HttpDevice implements IDeviceHandler{
    @Override
    public String start() {
        return "HttpDevice..start...";
    }
    @Override
    public String stop() {
        return "HttpDevice..stop...";
    }
}

打成jar:
device-mqtt-1.0-SNAPSHOT.jar
device-http-1.0-SNAPSHOT.jar
