使用java jxl读取excel中的内容，并生成json文件。

比较中间的汉字

package demo;

public class CharUtil {
    // 完整的判断中文汉字和符号

    public static boolean isChinese(String strName) {

        char[] ch = strName.toCharArray();

        for (int i = 0; i < ch.length; i++) {

            char c = ch[i];

            if (isChinese(c)) {

                return true;

            }

        }

        return false;

    }
    // 根据Unicode编码完美的判断中文汉字和符号

    private static boolean isChinese(char c) {

        Character.UnicodeBlock ub = Character.UnicodeBlock.of(c);

        if (ub == Character.UnicodeBlock.CJK_UNIFIED_IDEOGRAPHS

                || ub == Character.UnicodeBlock.CJK_COMPATIBILITY_IDEOGRAPHS

                || ub == Character.UnicodeBlock.CJK_UNIFIED_IDEOGRAPHS_EXTENSION_A

                || ub == Character.UnicodeBlock.CJK_UNIFIED_IDEOGRAPHS_EXTENSION_B

                || ub == Character.UnicodeBlock.CJK_SYMBOLS_AND_PUNCTUATION

                || ub == Character.UnicodeBlock.HALFWIDTH_AND_FULLWIDTH_FORMS

                || ub == Character.UnicodeBlock.GENERAL_PUNCTUATION) {

            return true;

        }

        return false;

    }

}

实体类

package demo;

import java.util.Date;

public class TimeZoneBean {
    private String cityName;
    private String countryName;
    private String timeZone;// 时区 GMT +8等等
    private String startTime;
    private String endTime;
    public String getCityName() {
        return cityName;
    }
    public void setCityName(String cityName) {
        this.cityName = cityName;
    }
    public String getCountryName() {
        return countryName;
    }
    public void setCountryName(String countryName) {
        this.countryName = countryName;
    }
    public String getTimeZone() {
        return timeZone;
    }
    public void setTimeZone(String timeZone) {
        this.timeZone = timeZone;
    }
    public String getStartTime() {
        return startTime;
    }
    public void setStartTime(String startTime) {
        this.startTime = startTime;
    }
    public String getEndTime() {
        return endTime;
    }
    public void setEndTime(String endTime) {
        this.endTime = endTime;
    }


}
