解决办法：

先通过去除表情符号的字符，然后再进行入库操作：

tbmNewsInfo.setSummary( filterOffUtf8Mb(newsInfo.getSummary()));

filterOffUtf8Mb处理表情格式的方法如下：

public static String filterOffUtf8Mb(String text) {
        String result = text;
        try {
            byte[] bytes = text.getBytes("utf-8");
            ByteBuffer buffer = ByteBuffer.allocate(bytes.length);
            int i = 0;
            while (i < bytes.length) {
                short b = bytes[i];
                if (b > 0) {
                    buffer.put(bytes[i++]);
                    continue;
                }
                b += 256; // 去掉符号位
                if (((b >> 5) ^ 0x06) == 0) {
                    buffer.put(bytes, i, 2);
                    i += 2;
                } else if (((b >> 4) ^ 0x0E) == 0) {
                    buffer.put(bytes, i, 3);
                    i += 3;
                } else if (((b >> 3) ^ 0x1E) == 0) {
                    i += 4;
                } else if (((b >> 2) ^ 0xBE) == 0) {
                    i += 5;
                } else {
                    i += 6;
                }
            }
            buffer.flip();
            result = new String(buffer.array(), "utf-8");
        } catch (Exception ex) {
            log.error("资讯内容过滤4字节字符出现错误" + ex.getMessage());
        }
        return result;
    }

原因定位：

主要是摘要这个字段，也是字符格式入库，需要把表情符号删除替换掉然后才能正常入库，然后数据库格式改成了mb4发现也不能支持。字符串修改之后，目前已经正常入库！
