Struts2.0 Internationalization

This article is transferred from: http://blog.sina.com.cn/s/blog_4934a04a0100dbkp.html

Thanks to the original author for sharing, I feel that the summary is good and I will post it for future use.

Struts2 is internationalized in three situations: Internationalization of foreground pages, internationalization of Action classes, and internationalization of configuration files.

First, specify the global resource file:

Introduce

<Constant name = "struts. Custom. i18n. Resources" value = "message"> </constant> (Note the location)

Or

Specify the following line in the Struts. properties file:

Struts. Custom. i18n. Resources = message

 

The specified state-based resource file is

Xxx _ language _ country. Properties

 

Message_zh_cn.properties (Simplified Chinese resource file)

Message_en_us.properties (US English resource file)

 

 

(1). Internationalization on the JSP page (using struts2 <s: Text.../> ):

 

<S: i18n name = "message">
 <S: Text name = "hello">
   <S: Param >$ {username} </S: param>
 </S: Text>
</S: i18n>

 

Message_en_us.properties file Configuration:

Hello = Hello world, {0}

Message_zh_cn.properties file Configuration:

Hello = Hello, {0}

 

(2) the label of the form element is internationalized:

Not internationalized:

<S: textfield name = "username" label = "username"> </S: textfield>

<S: textfield name = "password" label = "password"> </S: textfield>

 

After internationalization:

<S: textfield name = "username" Key = "uname"> </S: textfield>

<S: textfield name = "password" Key = "pword"> </S: textfield>

 

Message_en_us.properties file, Configuration:

Uname = Username

Pword = Password

 

Message_zh_cn.properties file, Configuration:

Uname = User Name

Pword = Password

 

 

(3) Internationalization in. Action:

Not internationalized:

This. addfielderror ("username", "the username error! ");

This. addfielderror ("password", "The Password error! ");

 

After internationalization:

This. addfielderror ("username", "username. error ");

This. addfielderror ("password", "password. error ");

 

Message_en_us.properties file Configuration:

Username. Error = the username error!

Password. Error = the Password error!

Message_zh_cn.properties file Configuration:

Username. Error = username error!

Username. Error = incorrect password!

 

(4). internationalization in the configuration file:

Take the input validation LoginAction-validation.xml as an example:

Not internationalized:

<Field name = "username">
<Field-validator type = "requiredstring">
<Param name = "trim"> true </param>
<Message> username shocould not be empty! </Message>
</Field-validator>

<Field-validator type = "stringlength">
<Param name = "minlength"> 6 </param>
<Param name = "maxlength"> 12 </param>
<Message> username shocould be between $ {minlength} and $ {maxlength }! </Message>
</Field-validator>
</Field>

 

After internationalization:

<Field name = "username">
<Field-validator type = "requiredstring">
<Param name = "trim"> true </param>
<Message key = "username. Empty! "> </Message>
</Field-validator>

<Field-validator type = "stringlength">
<Param name = "minlength"> 6 </param>
<Param name = "maxlength"> 12 </param>
<Message key = "username. Size"> </message>
</Field-validator>
</Field>
 

Message_en_us.properties file Configuration:

Username. Empty = the usernameShocould not be empty!

Username. size = the size of username shoule be between 6 and 12!

Password. Empty = the password shocould not be empty!

Password. size = the size of password shoule be between 6 and 12!

 

Message_zh_cn.properties file Configuration:

Username. Empty = username cannot be blank!

Username. size = username length: 6 to 12!

Password. Empty = password cannot be blank!

Password. size = the password length is 6 to 12!

Note: The international resource file message_zh_cn.properties cannot contain non-Western European characters..

Java provides a tool to process the Chinese characters in the file: native2ascii. This tool can be found under % java_home %/bin.
