支付相关(二)：APP支付宝支付-转账到支付宝账号(JAVA服务端开发）
首先确保签约单笔转账到支付宝账号
转账到支付宝账号是APP这边一个提现的功能。支付宝提供了可以转账到支付宝账号的功能，可选择收款方账户类型。可取值：
1、ALIPAY_USERID：支付宝账号对应的支付宝唯一用户号。以2088开头的16位纯数字组成。2、ALIPAY_LOGONID：支付宝登录号，支持邮箱和手机号格式。
a、转到支付宝唯一用户号，获取1ALIPAY_USERID的方式需要，支付宝授权才能拿到，下面会有代码实现
b、转账到支付宝登录号，APP可以选择让用户自己填邮箱和手机号
我是用的a方式，b方式具体参照payee_type参数介绍，单笔转账到支付宝账号
代码如下 ：
支付宝授权:
/**
* 组装支付宝授权登录信息
*/
@GetMapping("aliInfoStr")
public ResultModel getAliInfoStr(HttpServletRequest request, HttpServletResponse response){
ResultModel resultModel= new ResultModel();
String targetId = String.valueOf(UUID.next());
String signstr="";
String signs = "apiname=" + AliPayConfig.AUTH_API_NAME +
"&method=" + AliPayConfig.AUTH_API_METHOD +
"&app_id=" + AliPayConfig.APP_ID_USER +
"&app_name=" + AliPayConfig.AUTH_APP_NAME +
"&biz_type=" + AliPayConfig.AUTH_BIZ_TYPE +
"&pid=" + AliPayConfig.AUTH_PID +
"&product_id=" + AliPayConfig.AUTH_PRODUCT_ID +
"&scope=" + AliPayConfig.AUTH_SCOPE +
"&target_id=" + targetId +
"&auth_type=" + AliPayConfig.AUTH_TYPE +
"&sign_type=" + AliPayConfig.SIGN_TYPE ;
try {
signstr = AlipaySignature.rsaSign(signs,AliPayConfig.PRIVATE_KEY,AliPayConfig.CHARSET,AliPayConfig.SIGN_TYPE);
signstr=signs+"&sign="+signstr;
resultModel.setStatus(0);
resultModel.setMessage("支付宝授权串组装成功");
resultModel.setResultObject(signstr);
} catch (AlipayApiException e) {
e.printStackTrace();
}
return resultModel;
}组装返给APP，支付宝调能成功调起授权，把auth_code给服务端去获取用户信息
/**
* 获取acesstoken 获取用户信息
*/
@PostMapping("getAccessToken")
public ResultModel getAccessToken(@RequestBody OrderDto dto, HttpServletRequest request,
HttpServletResponse response) throws AlipayApiException {
ResultModel resultModel = new ResultModel();
AlipayClient alipayClient = new DefaultAlipayClient(AliPayConfig.URL, AliPayConfig.APP_ID_USER, AliPayConfig.PRIVATE_KEY, AliPayConfig.FORMAT, AliPayConfig.CHARSET,AliPayConfig.ALI_PUBLIC_KEY, AliPayConfig.SIGN_TYPE);
AlipaySystemOauthTokenRequest aliRequest = new AlipaySystemOauthTokenRequest();
aliRequest.setGrantType("authorization_code");
aliRequest.setCode(dto.getAliAuthCode());
AlipaySystemOauthTokenResponse aliResponse = alipayClient.execute(aliRequest);
String authTokenData = aliResponse.getBody();
JSONObject authTokenJsonObject = JSONObject.parseObject(authTokenData).getJSONObject("alipay_system_oauth_token_response");
if(aliResponse.isSuccess()){
System.out.println("调用成功");
System.out.println("调用成功");
//以下注释是拿到token后获取用户的全部信息，因为我只需要user_id ,没有再调用 ,app支持第三方登录时候可以放开使用
//String accessToken=authTokenJsonObject.getString("access_token");
// AlipayUserInfoShareRequest userInfoRequest = new AlipayUserInfoShareRequest();
// AlipayUserInfoShareResponse userInfoResponse = alipayClient.execute(userInfoRequest,accessToken);
// String userInfoData = aliResponse.getBody();
// JSONObject userInfoJsonObject = JSONObject.parseObject(userInfoData).getJSONObject("alipay_user_info_share_response");
// if(userInfoResponse.isSuccess()){
// System.out.println("调用成功");
// String userAliId = userInfoJsonObject.getString("user_id");
// } else {
// System.out.println("调用失败");
// }
String userAliId = authTokenJsonObject.getString("user_id");
int k = iMicroInquiryUserService.updateUserAliId(userAliId,dto.getUserId()); //此处就是更新一下user里aliOpenId字段，自己写吧，不贴了
if(k>0){
resultModel.setStatus(1);
resultModel.setMessage("绑定用户支付宝ID成功");
}else{
resultModel.setStatus(0);
resultModel.setMessage("绑定支付宝ID失败");
}
} else {
resultModel.setStatus(0);
resultModel.setMessage("绑定支付宝授权失败");
}
return resultModel;
}用到的dto
import java.io.Serializable;
/**

*/
public class TixianDto implements Serializable {
private static final long serialVersionUID = -27273789824211424L;

public Float getAmount() {
return amount;
}
public void setAmount(Float amount) {
this.amount = amount;

public Integer getTixianType() {

下面是转账到支付宝账号
