字符串中文提取

是否是中文

public boolean checkChinese(String chinese)
{
    Pattern p = Pattern.compile("[\u4e00-\u9fa5]");
    Matcher m = p.matcher(chinese);
    if (m.find()) {
        return true;
    }
    return false;
}

从文档中提取中文语句

48 return new ResultModel("修改成功");

59 return new ResultModel("添加成功");

106 return new ResultModel("修改成功");

180 return "数据为空";
187 return "添加成功";

@Test
public void getChineseforomFile(){
    List<String> stringsList = new ArrayList<>();
    FileReader fileReader = new FileReader("C:\\Users\\Administrator\\Desktop\\项目后台的中文提醒内容.txt");
    List<String> result = fileReader.readLines();
    
    for (String str : result) {
        String[] split = StrUtil.subBetweenAll(str, "\"", "\"");
        for (String s : split) {
            if(checkChinese(s)){
                stringsList.add(s);
            }
        }
    }
    stringsList = stringsList.stream().distinct().collect(Collectors.toList());
    stringsList.forEach(System.out::println);
