【微信支付】小案例,Java版_模拟微信支付小案例

模拟微信支付小案例

微信支付的简单实现案例(Java)

上手一个小案例,实现Java版本的微信支付。

第一步: 从微信平台下载微信支付demo。
链接: 到官方下载
这里我们下载Java版的。
注意微信提供的demo是myclipse版本的。
我们要用myclipse打开。
这里我们下载Java版本的demo
第二步:把demo导入到myclipse中去。
在这里插入图片描述
ps:过程中爆红的可以选择
(1)硬着头皮跟着做下去。
(2)拉到文章最后导入jar包。

第三步:配置代码。
(1) MyConfig.java

package com.github.wxpay.sdk;
import com.github.wxpay.sdk.WXPayConfig;
import java.io.*;
public class MyConfig extends WXPayConfig{
    private byte[] certData;
    public MyConfig() throws Exception {
    	//String certPath = "d:/tomcat/ssqc/webapps/wxpay-sdk/cert/apiclient_cert.p12";
        /*String certPath = "C:/Tomcat 8.5/webapps/wxpay-sdk/cert/apiclient_cert.p12";
        File file = new File(certPath);
        InputStream certStream = new FileInputStream(file);
        this.certData = new byte[(int) file.length()];
        certStream.read(this.certData);
        certStream.close();*/
    	//上面六行注释,要修改WXPay.java,注释掉63行
    }
    public String getAppID() {
        return "wx8397f8696b538317";
    }
    public String getMchID() {
        return "1473426802";
    }
    public String getKey() {
        return "T6m9iK73b0kn9g5v426MKfHQH7X8rKwb";
    }
    public InputStream getCertStream() {
        ByteArrayInputStream certBis = new ByteArrayInputStream(this.certData);
        return certBis;
    }
    public int getHttpConnectTimeoutMs() {
        return 8000;
    }
    public int getHttpReadTimeoutMs() {
        return 10000;
    }
//	@Override
//	IWXPayDomain getWXPayDomain() {
//		// TODO Auto-generated method stub
//		return null;
//	}
	//README.MD漏了这个类型:
	public IWXPayDomain getWXPayDomain() {
        // 这个方法需要这样实现, 否则无法正常初始化WXPay
    IWXPayDomain iwxPayDomain = new IWXPayDomain() {
        public void report(String domain, long elapsedTimeMillis, Exception ex) {
    
        }
        public DomainInfo getDomain(WXPayConfig config) {
            return new IWXPayDomain.DomainInfo(WXPayConstants.DOMAIN_API, true);
        }
    };
    return iwxPayDomain;
  }//public IWXPayDomain getWXPayDomain
}//public class MyConfig extends WXPayConfig
