签名model类：

public class JsConfigVo {	private String appId;		private String timestamp;		private String nonceStr;		private String signature;		private String url;	public String getAppId() {		return appId;	}	public void setAppId(String appId) {		this.appId = appId;	}	public String getTimestamp() {		return timestamp;	}	public void setTimestamp(String timestamp) {		this.timestamp = timestamp;	}	public String getNonceStr() {		return nonceStr;	}	public void setNonceStr(String nonceStr) {		this.nonceStr = nonceStr;	}	public String getSignature() {		return signature;	}	public void setSignature(String signature) {		this.signature = signature;	}	public String getUrl() {		return url;	}	public void setUrl(String url) {		this.url = url;	}	}
