一. 用注解翻译码表
1. 定义注解
@Documented
@Retention(RetentionPolicy.RUNTIME)
@Target(value={ElementType.FIELD})
public @interface DmTable {
public String value() ;
}
使用：把value=codeID
/**
* 与户主关系
*/
@DmTable("DM_HZGX")
private String yhzgxdm;
2. 反射翻译工具类
public class CodeTranslateUtil {
/**
* 根据传的类对象对属性值进行码表翻译
*
* @param object
*/
public void getCodeTranslate(Object object) {
Class<?> cls = object.getClass();
for (Field f : cls.getDeclaredFields()) {
f.setAccessible(true);
try {
Object o = f.get(object);
DmTable dt = f.getAnnotation(DmTable.class);
if (o != null && dt != null) {
String dmTable = dt.value();
try {
Object no = CodeInfoCacheUtils.getCodeValue(dmTable, String.valueOf(o));
f.set(object, no);
}catch (Exception e){
f.set(object, o);
}
}
DateFormat df = f.getAnnotation(DateFormat.class);
if (o != null && df != null) {
Object no = DateUtils.toDisplayStr(String.valueOf(o), DateConst.HYPHEN_DISPLAY_TIME);
f.set(object, no);
}
} catch (Exception e) {
e.printStackTrace();
}
}
cls = cls.getSuperclass();
}
}
3. 定义枚举
public enum MoudleEnum {
kdyrk("1", "跨地域人口", "","11111"),
jmsfzsl("2", "居民身份证管理查询", "","11112"),
jzzxcx("3", "流动人口及居住证查询", "","11113"),
czfcx("com.dragonsoft.rkcx.xsxml.entity.XmlCzfwczqk", "出租房承租", "/rkcx/chu_zu_ren_xin_xi","11117"),
xqdw("com.dragonsoft.rkcx.xsxml.entity.XmlXqdwjbxx", "辖区单位", "/rkcx/xqdw_xin_xi","11118"),
syrkcx("com.dragonsoft.rkcx.xsxml.entity.XmlRowInfoSyrk", "实有人口", "/rkcx/ren_xiang_zhanshi_list","11115"),
hjrkcx("com.dragonsoft.rkcx.xsxml.entity.XmlRowInfoHjgl", "户籍人口", "/rkcx/ren_xiang_zhanshi_list","11114"),
ldrkcx("com.dragonsoft.rkcx.xsxml.entity.XmlLdrkxx", "流动人口", "/rkcx/ren_xiang_zhanshi_list","11116"),
thrxx("111", "同户人", "",""),
jmsfzxx("112", "居民身份证信息", "",""),
bdgj("113", "变动轨迹", "",""),
sfz_slxxcx("com.dragonsoft.rkcx.xsxml.entity.JMSFSLEntity", "受理信息查询", "/rkcx/jzsfzsl_zhanshi_list","11119"),
sfz_zzhkxxcx("com.dragonsoft.rkcx.xsxml.entity.XmlJmsfzzzhkxx", "制证回馈信息查询", "/rkcx/jzsfzsl_zhanshi_list","11120"),
sfz_zlhkxxcx("com.dragonsoft.rkcx.xsxml.entity.XmlJmsfzzlkzhkxx", "质量回馈信息查询", "/rkcx/jzsfzsl_zhanshi_list","11121"),
jz_ldrkcx("com.dragonsoft.rkcx.xsxml.entity.XmlLdrkxx", "流动人口信息查询", "/rkcx/ldrkjzz_zhan_shi","11122"),
jz_zjxxcx("com.dragonsoft.rkcx.xsxml.entity.JZZZJEntity", "居住证信息查询", "/rkcx/ldrkjzz_zhan_shi","11123"),
;
private final String code;
private final String desc;
private final String url;
private final String typeId;
private MoudleEnum(String code, String desc, String url,String typeId) {
this.code = code;
this.desc = desc;
this.url = url;
this.typeId = typeId;
}
public String getDesc() {
return desc;
}
public String getCode() {
return code;
}
public String getUrl() {
return url;
}
public String getTypeId() {
return typeId;
}
}
4. 使用
/**
* 根据接口地址访问并且得到xml，解析数据
*
* @param result
* @param lb
* @return
* @throws Exception
*/
public Map<String, Object> getHttpClineXmldata(String result, String lb, String sf) throws Exception {
Map<String, Object> map = new HashMap<>(16);
for (MoudleEnum mouem : MoudleEnum.values()) {
if (mouem.getDesc().equals(lb)) {
XmlData xmlData = ResponseXmlFactory.handleXml(strReplaceinfos(result));
Class<?> obj = Class.forName(mouem.getCode());
String xp = null;
if (INTERFACRRESULTCODE.equals(xmlData.getCode())) {
String num = xmlData.getXmlRecord().get(0).getXmlResult().getNum();
if (StringUtils.isNotBlank(num) && !NUMSTR.equals(num)) {
List<?> rkcxInfoAll = xmlData.getXmlRecord().get(0).getXmlResult().getRkcxInfoAll(obj);
//码表翻译
CodeTranslateUtil codeTranslateUtil = new CodeTranslateUtil();
for (int i = 0; i < Integer.parseInt(num); i++) {
codeTranslateUtil.getCodeTranslate(rkcxInfoAll.get(i));
Object entity = rkcxInfoAll.get(i);
if (entity instanceof PhotoGetterInterface) {
xp = ((PhotoGetterInterface) entity).getXp();
//将照片添加至缓存
GuavaCacheUtils.addCache(((PhotoGetterInterface) entity).getCacheKey(), xp);
}
}
//列表頁面信息展示
map.put("list", JsonUtils.fromObject(rkcxInfoAll));
//实有人口详情页,以及查询流动人口详情页
map.put("persion_infos", rkcxInfoAll.get(0));
//添加查询记录
saveQueryRecord(rkcxInfoAll, mouem.getTypeId(), sf);
}
}
}
}
return map;
}
二. Java中16进制与字符串之间的相互转换
字符串转为16进制后再转回来,英文正常,中文出现乱码
- 在将字符串转为16进制之前先进行一次转化,先将其转化成为Unicode编码(相当于把中文用英文字符代替),再转化成为16进制
- 相反的,在十六进制转换为字符串后的得到的是Unicode编码,此时再将Unicode编码解码即可获取原始字符串
字符串转化为Unicode编码
/**
* 字符串转换unicode
*/
public static String string2Unicode(String string) {
StringBuffer unicode = new StringBuffer();
for (int i = 0; i < string.length(); i++) {
// 取出每一个字符
char c = string.charAt(i);
// 转换为unicode
unicode.append("\\u" + Integer.toHexString(c));
}
return unicode.toString();
}
字符串转为16进制
/**
* 字符串转化成为16进制字符串
* @param s
* @return
*/
public static String strTo16(String s) {
String str = "";
for (int i = 0; i < s.length(); i++) {
int ch = (int) s.charAt(i);
String s4 = Integer.toHexString(ch);
str = str + s4;
}
return str;
}
16进制转为字符串
/**
* 16进制转换成为string类型字符串
* @param s
* @return
*/
public static String hexStringToString(String s) {
if (s == null || s.equals("")) {
return null;
}
s = s.replace(" ", "");
byte[] baKeyword = new byte[s.length() / 2];
for (int i = 0; i < baKeyword.length; i++) {
try {
baKeyword[i] = (byte) (0xff & Integer.parseInt(s.substring(i * 2, i * 2 + 2), 16));
} catch (Exception e) {
e.printStackTrace();
}
}
try {
s = new String(baKeyword, "UTF-8");
new String();
} catch (Exception e1) {
e1.printStackTrace();
}
return s;
}
Unicode转为字符串
/**
* unicode 转字符串
*/
public static String unicode2String(String unicode) {
StringBuffer string = new StringBuffer();
String[] hex = unicode.split("\\\\u");
for (int i = 1; i < hex.length; i++) {
// 转换出每一个代码点
int data = Integer.parseInt(hex[i], 16);
// 追加成string
string.append((char) data);
}
return string.toString();
}
此方法虽然解决了转化过程中中文乱码的问题,但是过于复杂,笔者后来又发现一种新的转化方式,可直接转化,中文不乱码,代码如下:
字符串转16进制
/**
* 字符串转换成为16进制(无需Unicode编码)
* @param str
* @return
*/
public static String str2HexStr(String str) {
char[] chars = "0123456789ABCDEF".toCharArray();
StringBuilder sb = new StringBuilder("");
byte[] bs = str.getBytes();
int bit;
for (int i = 0; i < bs.length; i++) {
bit = (bs[i] & 0x0f0) >> 4;
sb.append(chars[bit]);
bit = bs[i] & 0x0f;
sb.append(chars[bit]);
// sb.append(' ');
}
return sb.toString().trim();
}
16进制转为字符串
/**
* 16进制直接转换成为字符串(无需Unicode解码)
* @param hexStr
* @return
*/
public static String hexStr2Str(String hexStr) {
String str = "0123456789ABCDEF";
char[] hexs = hexStr.toCharArray();
byte[] bytes = new byte[hexStr.length() / 2];
int n;
for (int i = 0; i < bytes.length; i++) {
n = str.indexOf(hexs[2 * i]) * 16;
n += str.indexOf(hexs[2 * i + 1]);
bytes[i] = (byte) (n & 0xff);
}
return new String(bytes);
}
