Before I thought that MySQL set Utf-8 and nickname Decode after everything, the results only recently found that the 4-byte expression will be an error.The error message is as follows:Data:nullmessage: "###Errorupdatingdatabase.Cause:java.sql.SQLException: incorrectstringvalue: ' \xf0\x9f\x98\x86\xf0\x9f ' forcolumn ' nickname ' atrow1###Theerrormayinvolve Com.smallfoxdog.demo.mapper.usermapper.insertuser-inline###theerroroccurredwhile settingparamete

The newly-bought X98 tablet is an old version of the system, is not conducive to Win8 touch screen operation, so as long as we will be X98 brush into a perfect Win8 system, you can let the tablet computer has the functions of computers, even some ordinary computers do not have the function it can have, is it incredible? Of course, before the brush into the WIN8 system, we'd better upgrade its firmware first

Data removed from the network can not be inserted into the database after parsing, prompting a field problem, the problem is as follows:Sqlexception:incorrect string value: ' \xf0\x9f\x98\x84 ' for column ' Wei_content ' at row 1After reviewing the data, it was found that the emoji character and database were different and could not be stored directlySolution One:Remove the emoji characters from the content:public string Removenonbmpunicode (String st

Ordinary string or expression is a placeholder 3 bytes, so utf8 enough, but the mobile side of the emoji placeholder is 4 bytes, the ordinary utf8 is not enough, in order to deal with the wireless internet opportunities and challenges, to avoid the problem of emoji emoticons, involving wireless-related MySQL Database recommendations are in advance using the UTF8MB4 character set, which must be a key element in the mobile Internet industry's technology selection MySQL version limit, MySQL 5.5.

First, this is the coding problem.The solution is to erase the data and create one.Today, after inserting a piece of data, we find that the data inserted in the database is garbled, and then we look at the MySQL code.Show variables Likem '%character% ', and then sure enough in the client is Latin, then go find tutorials http://blog.csdn.net/crave_shy/article/details/23345869Then follow the tutorial to modify the database encoding, and then, in the execution of a program, there is the error above

Today, while climbing the NetEase Cloud music song commentary, when inserting data into the MySQL database, incorrect string value: ' \xf0\x9f\x98\xad ',... ' for column ' commentcontent ' Row 1 This error, Google found that the original is due to the database coding problem, because we have a emoj expression in the comment data, and these expressions are encoded in a unit of four bytes, And we usually use the Utf-8 encoding in the MySQL database by d

version is less than 5.5.3, the version upgrade is done first, and then the corresponding data type is changed to the UTF8MB4 type. If you are using a connector/j connection database, you need to change the encoding format to UTF8MB4 (set character_set_server=utf8mb4 in the Connection config) in the configuration. 2) Custom filter rules that filter or convert the four-byte UTF-8 characters that appear in the text to a custom type.Transferred from: http://blog.csdn.net/fuxuejun/article/details/2

Set_results,character_set_server are modified to UTF8MB4, but I did not do this step, but also normal, so it may be that this step is superfluous, if you need to change, follow the instructions below to make changes.3 Modifying the MySQL configuration file my.cnf (Windows My.ini)MY.CNF generally in the etc/mysql/my.cnf position. When you find it, add the following three sections:[Client]Default-character-set = Utf8mb4[MySQL]Default-character-set = Utf8mb4[Mysqld]Character-set-client-handshake =

the MySQL 5.5.3. Solution: 1) using the UTF8MB4 data type To use this strategy, if the MySQL version is less than 5.5.3, the version upgrade is done first, and then the corresponding data type is changed to the UTF8MB4 type. If you are using a connector/j connection database, you need to change the encoding format to UTF8MB4 (set character_set_server=utf8mb4 in the Connection config) in the configuration. 2) Custom filter rules that filter or convert the four-byte UTF-8 characters that appear

1. Cause of Error:The MySQL utf-8 code stores 2-3 bytes, while emoji is 4 bytes.2. Workaround:Modify the MySQL configuration file, under Windows for My.ini (Linux for my.cnf), the same content is modified.[Client]default-character-set = Utf8mb4[mysql]default-character-set = Utf8mb4[mysqld]character-set-server = Utf8mb4collation-server = Utf8mb4_unicode_ci3. Change the corresponding field in the database to Utf8mb4_general_ci4. In my project, configure the database link URL to the properties file

When converting a binary stream, you can input the encoding parameter to indicate the encoding format used to read the byte array. The errors parameter indicates the error level for reading binary data. (The two parameters have the same value and similar meanings as the parameters of the same name in the open method.

Some time ago, we performed a USB copy test and accumulated several test scripts. We can also copy data between disks and store them here for backup. Main functions: Copy data from one storage device to another, compare the two copies to see if they are consistent, and determine whether an error occurs in the system; Three methods are used to intuitively reflect the copy situation. For more information, see method 3. 1. Run the rsync command to copy the file, and display the file size dynamical
