一.项目简介
1.环境
1).jdk 1.6
2.jar包
commons-net-1.4.1.jar
gson-2.2.4.jar
jar 建议大家去官网上下载
3.项目结构
二.创建Json
1.javaBean
package kingdom.json;public class TransData { private String fq_name; //交易发起人 private String js_name; //交易接收人 private String hl_name; //交易处理人 private int money; //交易金额 private int pay_way; //支付方式 private String begin_time; //交易发起时间 private String end_time; //交易结束时间 public String getFq_name() { return fq_name; } public void setFq_name(String fq_name) { this.fq_name = fq_name; } public String getJs_name() { return js_name; } public void setJs_name(String js_name) { this.js_name = js_name; } public String getHl_name() { return hl_name; } public void setHl_name(String hl_name) { this.hl_name = hl_name; } public int getMoney() { return money; } public void setMoney(int money) { this.money = money; } public int getPay_way() { return pay_way; } public void setPay_way(int pay_way) { this.pay_way = pay_way; } public String getBegin_time() { return begin_time; } public void setBegin_time(String begin_time) { this.begin_time = begin_time; } public String getEnd_time() { return end_time; } public void setEnd_time(String end_time) { this.end_time = end_time; }}package kingdom.json;import java.util.List;public class DataGram { private String trans_code; //交易代码 private String trans_type; //交易类型 private String trans_name; //交易名称 private String jys_code; //交易所代码 private String jys_name; //交易所名字 private String jy_way; //交易方式 private List<TransData> ts_data; //交易数据 public String getTrans_code() { return trans_code; } public void setTrans_code(String trans_code) { this.trans_code = trans_code; } public String getTrans_type() { return trans_type; } public void setTrans_type(String trans_type) { this.trans_type = trans_type; } public String getTrans_name() { return trans_name; } public void setTrans_name(String trans_name) { this.trans_name = trans_name; } public String getJys_code() { return jys_code; } public void setJys_code(String jys_code) { this.jys_code = jys_code; } public String getJys_name() { return jys_name; } public void setJys_name(String jys_name) { this.jys_name = jys_name; } public String getJy_way() { return jy_way; } public void setJy_way(String jy_way) { this.jy_way = jy_way; } public List<TransData> getTs_data() { return ts_data; } public void setTs_data(List<TransData> ts_data) { this.ts_data = ts_data; }}2.创建Json
package kingdom.json;import java.util.List;import java.util.ArrayList;import com.google.gson.Gson;public class CreatJson { public static String CreatTransJson() { String beanStr = null; DataGram dg = new DataGram(); Gson gson = new Gson(); TransData td = new TransData(); List<TransData> list = new ArrayList<TransData>(); dg.setTrans_code("10016"); dg.setTrans_type("转账"); dg.setTrans_name("发行债券"); dg.setJys_code("009"); dg.setJys_name("北京金融交易所"); dg.setJy_way("债券"); dg.setTs_data(list); for(int i = 0; i < 3; ++i) { td.setFq_name("小明"); td.setJs_name("小王"); td.setHl_name("小张"); td.setMoney(100000 + i); td.setBegin_time("2017-03-09"); td.setEnd_time("2017-09-22"); list.add(td); } beanStr = gson.toJson(dg); return beanStr; }}3.json数据格式
{ "trans_code":"10016", "trans_type":"转账", "trans_name":"发行债券", "jys_code":"009", "jys_name":"北京金融交易所", "jy_way":"债券", "ts_data": [ { "fq_name":"小明", "js_name":"小王", " hl_name":"小张"," money":100002, "pay_way":0, "begin_time":"2017-03-09", "end_time":"2017-09-22" } , { "fq_name":"小明", "js_name":"小王", " hl_name":"小张"," money":100002, "pay_way":0, "begin_time":"2017-03-09", "end_time":"2017-09-22" } , { "fq_name":"小明", "js_name":"小王", " hl_name":"小张"," money":100002, "pay_way":0, "begin_time":"2017-03-09", "end_time":"2017-09-22" } ]}三.解析Json并创建XML
1.JavaBean代码
package kingdom.xml;import java.util.List;public class Result { private String trans_code; private String trans_type; private String trans_name; private String jys_code; private String jys_name; private String jy_way; private List<TranInfo> ts_data; public String getTrans_code() { return trans_code; } public void setTrans_code(String trans_code) { this.trans_code = trans_code; } public String getTrans_type() { return trans_type; } public void setTrans_type(String trans_type) { this.trans_type = trans_type; } public String getTrans_name() { return trans_name; } public void setTrans_name(String trans_name) { this.trans_name = trans_name; } public String getJys_code() { return jys_code; } public void setJys_code(String jys_code) { this.jys_code = jys_code; } public String getJys_name() { return jys_name; } public void setJys_name(String jys_name) { this.jys_name = jys_name; } public String getJy_way() { return jy_way; } public void setJy_way(String jy_way) { this.jy_way = jy_way; } public List<TranInfo> getTs_data() { return ts_data; } public void setTs_data(List<TranInfo> ts_data) { this.ts_data = ts_data; } public static class TranInfo { private String fq_name; private String js_name; private String hl_name; private int money; @Override public String toString() { return "TranInfo [money=" + money + ", pay_way=" + pay_way + "]"; } private int pay_way; private String begin_time; private String end_time; public String getFq_name() { return fq_name; } public void setFq_name(String fq_name) { this.fq_name = fq_name; } public String getJs_name() { return js_name; } public void setJs_name(String js_name) { this.js_name = js_name; } public String getHl_name() { return hl_name; } public void setHl_name(String hl_name) { this.hl_name = hl_name; } public int getMoney() { return money; } public void setMoney(int money) { this.money = money; } public int getPay_way() { return pay_way; } public void setPay_way(int pay_way) { this.pay_way = pay_way; } public String getBegin_time() { return begin_time; } public void setBegin_time(String begin_time) { this.begin_time = begin_time; } public String getEnd_time() { return end_time; } public void setEnd_time(String end_time) { this.end_time = end_time; } }}2.解析Json并创建XML文件
