I. Principles

The entire application of all parts, using a unified code.

second, the inspection steps

Depending on the principles above, you can consider the following steps:

For example, select a uniform UTF-8 encoding (similar to other encodings);

1 , the encoding of the file

Open a text file (HTML, FTL, JSP, shtml) using a tool such as EmEditor to set the encoding, and save the file as a UTF-8 encoded encoding format

2 , UrlEncode

If it involves passing parameters through a URL, you need to set it.

The value of the parameter is usually UTF-8 encoded using Urlencoder.encode.

3 , Filter the configuration

Consider adding a global filter filter to set the encoding UTF-8.

4 , the server operating system encoding configuration

Windows systems generally do not have problems, and Linux systems need to set the system's encoding.

Modify/etc/sysconfig/i18n file to increase

Lang= "en_US. UTF-8 "

Lang= "ZH_CN. UTF-8 "

Lang= "ZH_CN. GB18030 "

Lang= "zh_cn.gb2312"

And so on and make the changes take effect

5 , the Application server encoding configuration

For example, for Tomcat, you can modify

<connector executor= "Tomcatthreadpool"

port= "8080" protocol= "http/1.1"

connectiontimeout= "20000"

redirectport= "8443"/>

Paragraph, increase

Uriencoding= "UTF-8"

6 , DB the encoding configuration

The DB encoding is also set to be the same as the global encoding.

For example, for MySQL, all tables are created, adding Charset=utf8 settings.

7 , other

 

When the Java code is connected to the database, the connection string is written to add the encoding settings.

For example, add Characterencoding=utf8

Jdbc:mysql://localhost:3306/forandever?characterencoding=utf8
