重點(diǎn)是這句

{“type”:“token_mgr_error”,“reason”:“token_mgr_error: Lexical error at line 1, column 5. Encountered: after : “””}

我們在查詢的時候包含特殊字符：“”

所以為了避免搜索出錯，我們需要對查詢的字符串先進(jìn)行轉(zhuǎn)義文章來源地址http://www.zghlxwxcb.cn/news/detail-591269.html

public static String escape(String s) {
        StringBuilder sb = new StringBuilder();
        for (int i = 0; i < s.length(); i++) {
            char c = s.charAt(i);
            if (c == '\\' || c == '+' || c == '-' || c == '!' || c == '(' || c == ')' || c == ':'
                    || c == '^' || c == '[' || c == ']' || c == '\"' || c == '{' || c == '}' || c == '~'
                    || c == '*' || c == '?' || c == '|' || c == '&' || c == '/') {
                sb.append('\\');
            }
            sb.append(c);
        }
        return sb.toString();
    }

到了這里，關(guān)于ES搜索特殊字符異常Encountered: ＜EOF＞ after的文章就介紹完了。如果您還想了解更多內(nèi)容，請?jiān)谟疑辖撬阉鱐OY模板網(wǎng)以前的文章或繼續(xù)瀏覽下面的相關(guān)文章，希望大家以后多多支持TOY模板網(wǎng)！
