支付宝商户转账给支付宝个人

首先引入支付宝的jar

<dependency>
    <groupId>com.alipay.sdk</groupId>
    <artifactId>alipay-sdk-java</artifactId>
    <version>3.3.49.ALL</version>
</dependency>

然后调用支付宝转账

        AlipayClient alipayClient = new DefaultAlipayClient("https://openapi.alipay.com/gateway.do", "APP_ID", "APP_PRIVATE_KEY", "JSON", "UTF-8", "ALIPAY_PUBLIC_KEY", "RSA2");
        AlipayFundTransToaccountTransferRequest request = new AlipayFundTransToaccountTransferRequest();
        request.setBizContent("{" +
                "\"out_biz_no\":\""+System.currentTimeMillis()+"\"," +
                "\"trans_amount\":0.1," +
                "\"product_code\":\"TRANS_ACCOUNT_NO_PWD\"," +
                "\"biz_scene\":\"DIRECT_TRANSFER\"," +
                "\"order_title\":\"支付宝转账测试\"," +
                "\"payee_info\":{" +
                    "\"identity\":\"你的支付宝号\"," +
                    "\"identity_type\":\"ALIPAY_LOGON_ID\"," +
                    "\"name\":\"你的真实姓名\"" +
                    "    }," +
                "\"remark\":\"单笔转账\"," +
                "  }");
        AlipayFundTransToaccountTransferResponse response=null;
        Map<String, Object> map = new HashMap<String,Object>();
        try{
            log.info("转账发送---,参数为:{}",request.getBizContent());
            response = alipayClient.execute(request);
            if("10000".equals(response.getCode())){
                map.put("code", response.getCode());
                map.put("success", "true");
                map.put("des", "转账成功");
                log.info("转账成功,返回参数:{}",response);
            }else{
                map.put("code", response.getCode());
                map.put("sub_code", response.getSubCode());//详情状态码
                map.put("success", "false");
                map.put("sub_msg", response.getSubMsg());//详情原因
                log.info("转账失败,返回参数:{}",response);
            }
        }catch(AlipayApiException e){
            e.printStackTrace();
            map.put("success", "false");
            map.put("des", "转账失败！");
        }
        return map;

    }
