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\","
