我在 red5 中为作业调度程序创建了以下抽象类:
package com.demogames.jobs;
import com.demogames.demofacebook.MysqlDb;
import org.red5.server.api.IClient;
import org.red5.server.api.IConnection;
import org.red5.server.api.IScope;
import org.red5.server.api.scheduling.IScheduledJob;
import org.red5.server.api.so.ISharedObject;
import org.apache.log4j.Logger;
import org.red5.server.api.Red5;
/**
*
* @author ufk
*/
abstract public class DemoJob implements IScheduledJob {
protected IConnection conn;
protected IClient client;
protected ISharedObject so;
protected IScope scope;
protected MysqlDb mysqldb;
protected static org.apache.log4j.Logger log = Logger
.getLogger(DemoJob.class);
protected DemoJob (ISharedObject so, MysqlDb mysqldb){
this.conn=Red5.getConnectionLocal();
this.client = conn.getClient();
this.so=so;
this.mysqldb=mysqldb;
this.scope=conn.getScope();
}
protected DemoJob(ISharedObject so) {
this.conn=Red5.getConnectionLocal();
this.client=this.conn.getClient();
this.so=so;
this.scope=conn.getScope();
}
protected DemoJob() {
this.conn=Red5.getConnectionLocal();
this.client=this.conn.getClient();
this.scope=conn.getScope();
}
}
然后我创建了一个简单的类来扩展前一个类:
public class StartChallengeJob extends DemoJob {
public void execute(ISchedulingService service) {
log.error("test");
}
}
问题是我的主应用程序只能看到没有任何参数的构造函数。意味着我可以做到new StartChallengeJob()
为什么主应用程序看不到所有的构造函数?
谢谢!
