Java将Unicode转中文汉字

例如:将“\u5317\u4eac\u767e\u5ea6\u7f51\u8baf\u79d1\u6280\u6709\u9650\u516c\u53f8”转换成“北京百度网讯科技有限公司”


public static String convertUnicode(String ori){
        char aChar;
        int len = ori.length();
        StringBuffer outBuffer = new StringBuffer(len);
        for (int x = 0; x < len;) {
            aChar = ori.charAt(x++);
            if (aChar == '\\') {
                aChar = ori.charAt(x++);
                if (aChar == 'u') {
                    // Read the xxxx
                    int value = 0;
                    for (int i = 0; i < 4; i++) {
                        aChar = ori.charAt(x++);
                        switch (aChar) {
                        case '0':
                        case '1':
                        case '2':
                        case '3':
                        case '4':
                        case '5':
                        case '6':
                        case '7':
                        case '8':
                        case '9':
                            value = (value << 4) + aChar - '0';
                            break;
                        case 'a':
                        case 'b':
                        case 'c':
                        case 'd':

                            break;
                        default:
                            throw new IllegalArgumentException(
                                    "Malformed   \\uxxxx   encoding.");
