Type mismatch: cannot convert from Message to MessageDao

错误是Type mismatch: cannot convert from Message to MessageDao

beans

public class Message {
	private int messageID;
	private String messageTitle;
	private String messageContext;
	private Date publishTime;
	private int employeeID;
	
	public int getMessageID() {
		return messageID;
	}
	public void setMessageID(int messageID) {
		this.messageID = messageID;
	}
	public String getMessageTitle() {
		return messageTitle;
	}
	public void setMessageTitle(String messageTitle) {
		this.messageTitle = messageTitle;
	}
	public String getMessageContext() {
		return messageContext;
	}
	public void setMessageContext(String messageContext) {
		this.messageContext = messageContext;
	}
	public int getEmployeeID() {
		return employeeID;
	}
	public void setEmployeeID(int employeeID) {
		this.employeeID = employeeID;
	}
	public Date getPublishTime() {
		return publishTime;
	}
	public void setPublishTime(Date publishTime) {
		this.publishTime = publishTime;
	}
}

public interface MessageDao {
	public void addMessage(Message message);
	public void delMessage(int messageID);
	public Message findMessageByID(int messageID);
	public void updataMessage(Message message);
	public List<Message> findAllMessages(Page page);
	public int findAllCount();	
}

public class MessageDaoFactory {
	public static Message createMassage(){
		return new Message();
		
	}
}

错误在此：

MessageDao messageDao=MessageDaoFactory.createMassage();//此处报错
Page newPage=PageDetails.createPage(5, 1,messageDao.findAllCount());

Message 和 MessageDao　没关系，你看下你的　Message 　没实现，没继承怎么返回。

public class MessageDaoFactory {
    public static MessageDao createMassage(){
        return new MessageDao ();
         
    }
}

引用 2 楼 huxiweng 的回复:

public class MessageDaoFactory {
    public static MessageDao createMassage(){
        return new MessageDao ();
         
    }
}

太感谢了 版主！！！
