java.lang.NoSuchMethodException ()

今天使用Mybatis連接數據庫時報出了java.lang.NoSuchMethodException 的錯誤,錯誤信息如下，

錯誤提示，出錯地點是Player的BEAN類實例化出了錯，Player代碼如下

public class Player {
	private int pid;
	private String pname;
	private String position;
	private int cid;
	private Club club;//多對一關係
	
	public int getPid() {
		return pid;
	}
	public void setPid(int pid) {
		this.pid = pid;
	}
	public String getPname() {
		return pname;
	}
	public void setPname(String pname) {
		this.pname = pname;
	}
	public String getPosition() {
		return position;
	}
	public void setPosition(String position) {
		this.position = position;
	}
	public int getCid() {
		return cid;
	}
	public void setCid(int cid) {
		this.cid = cid;
	}
	public Club getClub() {
		return club;
	}
	public void setClub(Club club) {
		this.club = club;
	}
	
	public Player(int pid, String pname, String position, int cid, Club club) {
		super();
		this.pid = pid;
		this.pname = pname;
		this.position = position;
		this.cid = cid;
		this.club = club;
	}
	@Override
	public String toString() {
		return "Player [pid=" + pid + ", pname=" + pname + ", position=" + position + ", cid=" + cid + "]";
	}
	
}

最後發現是我在代碼最後寫了個有參構造，重載了構造函數，而Mybatis在load進一個bean類時，需要無參構造從而導致了該錯誤，

解決方法，給代碼加上午參構造即可！

public Player() {
		super();
	}
