�W�一节讲�?ji��n)怎么准备所有的参数�Q�这里讲怎么��这些参数组成xml�Q�即要通过HTTPS发送的数据�Q?/span>

大家可以先在�|�上�?ji��n)解一下java bean转xml的相关知�?/div>

1、我��Z��(ji��n)里一个请求参数类

public class WechatCashHongbaoSendReq {

private String nonce_str; //随机字符�?/div>

private String sign; //�{�֐�

private String mch_billno; //商户订单�?/div>

private String mch_id; //商户�?/div>

private String wxappid; //公众账号appid

private String send_name; //商户名称

private String re_openid; //用户openid

private int total_amount; //付款金额

private int total_num; //�U�包发放��M�h�?/div>

private String wishing; //�U�包��福�?/div>

private String client_ip; //Ip地址

private String act_name; //�z�d��名称

private String remark; //备注

public String getNonce_str() {

return nonce_str;

}

public void setNonce_str(String nonce_str) {

this.nonce_str = nonce_str;

}

public String getSign() {

return sign;

}

public void setSign(String sign) {

this.sign = sign;

}

public String getMch_billno() {

return mch_billno;

}

public void setMch_billno(String mch_billno) {

this.mch_billno = mch_billno;

}

public String getMch_id() {

return mch_id;

}

public void setMch_id(String mch_id) {

this.mch_id = mch_id;

}

public String getWxappid() {

return wxappid;

}

public void setWxappid(String wxappid) {

this.wxappid = wxappid;

}

public String getSend_name() {

return send_name;

}

public void setSend_name(String send_name) {

this.send_name = send_name;

}

public String getRe_openid() {

return re_openid;

}

public void setRe_openid(String re_openid) {

this.re_openid = re_openid;

}

public int getTotal_amount() {

return total_amount;

}

public void setTotal_amount(int total_amount) {

this.total_amount = total_amount;

}

public int getTotal_num() {

return total_num;

}

public void setTotal_num(int total_num) {

this.total_num = total_num;

}

public String getWishing() {

return wishing;

}

public void setWishing(String wishing) {

this.wishing = wishing;

}

public String getClient_ip() {

return client_ip;

}

public void setClient_ip(String client_ip) {

this.client_ip = client_ip;

}

public String getAct_name() {

return act_name;

}

public void setAct_name(String act_name) {

this.act_name = act_name;

}

public String getRemark() {

return remark;

}

public void setRemark(String remark) {

this.remark = remark;

}

2、然后把13个参数都set�q�去

WechatCashHongbaoSendReq sendReq = new WechatCashHongbaoSendReq();

sendReq.setNonce_str(nonce_str);

sendReq.setSign(sign);

sendReq.setMch_billno(mch_billno);

sendReq.setMch_id(mch_id);

sendReq.setWxappid(wxappid);

sendReq.setSend_name(send_name);

sendReq.setRe_openid(re_openid);

sendReq.setTotal_amount(total_amount);

sendReq.setTotal_num(total_num);

sendReq.setWishing(wishing);

sendReq.setClient_ip(client_ip);

sendReq.setAct_name(act_name);

sendReq.setRemark(remark);

3、将��h��c��{为xml

String data = Util.bean2XML(req).replaceAll("__", "_"); //��Z��么要加一个replaceAll("__", "_"),如果不加�Q�会(x��)有什么情况，大家可以试试

Java获取根目录，��d��配置文�g

休息食客 — Fri, 30 Jan 2015 07:01:00 GMT

Java获取根目录�\径有很多�U�方法，但是�Ҏ(gu��)��应用�E�序所部��v的环境和中间件不同，获取的�\径可能也不同。下面我提供一�U�方法，解决�q�个问题�?br />
         String path = InterfaceConfig.class.getResource("").getPath().toString();//获取�c�L��在�\�?br />        if (path.contains(".jar")) {
             path = path.replace("/", File.separator);//��?换成\�Q�如果是linux环境�Q�还�?
             path = path.replace("file:", "");//��L��file
             path = path.replace("classes\\", "");//��L��classes\
             if (path.startsWith("\\")) {
                 path = path.substring(1);//��L��W�一个\,如：(x��)、\D:\TongWeb... ,在linux上没有这�U�情�?br />             }
             path = path.split("WEB-INF")[0]+"WEB-INF"+File.separator+"classes";
        } else {
             path = InterfaceConfig.class.getResource("/").getPath().toString();//获取根�\�?br />        }
        File file = new File(path + File.separator + "InterfaceConfig.xml");

�q�段代码什么意思呢�Q?br />1、第一行是获取InterfaceConfig.class�q�个�c�L��在的路径�Q�这个InterfaceConfig.class可以换成你这�D�代码所在的�c�R�?br />2、判断�\径中是否包含.jar�Q�就是说�q�段代码所在的�c�L��l�构建的时候是不是打入jar包里�Q�如果在jar包里�Q�就��L��一些内容，如file: ,classes\\,
    然后�Ҏ(gu��)��WEB-INF切割�Q��ƈ拼出根目录�?br />3、如果没有打入jar包，那更��单了(ji��n)�Q�直接通过获取根�\径方法就解决�?ji��n)�?br />4、最后读取classes路径下的InterfaceConfig.xml配置文�g�?br />
