21 minutes struts resolve international issues and Chinese
Struts framework of the current application has been very mature, the basic configuration I do not say much, everyone on google found to have found a lot of the recent development of a project met the Struts I18N question, I turn to the basic rough used to give you some of the internationalization of the issue Struts have a brief understanding (Note, the following is in the struts of the development environment configured under the situation of international steps to solve the Chinese way):
1. Settings all JSP pages charset as UTF-8. That is added before each JSP pages <% @ page language = "java" contentType = "text / html; charset = UTF-8"%>. Java is unicode through internationalization, but unicode and UTF-8 is one-to-one relationship.
2. JSP pages contain no hard-coded text (that is, the text pages are from the inside *. properties resource documents read out, with <bean: message key = "keyword in property file"> can be read.) Resource allocation is to say, with distribution in the web.xml like inside. following assumptions English resource file called ApplicationResources_en.properties, Chinese source told ApplicationResources_xx.properties (value are Chinese). onboard with JDK Chinese native2ascii tools to document the resources inside the Chinese into ASCII representation for the use of Unicode encoding, ordered as follows: native2ascii-encoding GBK ApplicationResources_xx.properties ApplicationResources_zh.properties. (Chinese GBK is the default operating system inside, it is the expansion of gb2312 Set) , well, if you do not have form-Chinese, not storage, then you succeed. opened in the internet browser setup options to try languages. easy bar, huh. involves the following steps to storage problems.
3. Write a Filter categories, one of the most simple code examples are as follows:
Import java.io. *;
Import javax.servlet .*;
Public class CharsetFilter implements Filter (
Private FilterConfig config = null;
Private String defaultEncode = "UTF-8";
Public void init (FilterConfig config) throws ServletException (
This.config = config;
If (config.getInitParameter ( "Charset")! = Null) (
DefaultEncode = config.getInitParameter ( "Charset");
)
)
Public void destroy () (
This.config = null;
)
Public void doFilter (ServletRequest request, ServletResponse response,
FilterChain chain) throws IOException, ServletException (
ServletRequest srequest = request;
Srequest.setCharacterEncoding (defaultEncode);
Chain.doFilter (srequest, response);
)
)
Then you need to set up inside in the web.xml Filter, can be added the following (note that if you are inside JBX development, the statement must filter in a statement <servlet> front, otherwise they will be error, but by the time seemed no problem.)
<filter>
<filter-name> Character Encoding </ filter-name>
<filter-class> Com.alex.util.CharsetEncodingFilter </ filter-class>
</ Filter>
<filter-mapping>
<filter-name> Character Encoding </ filter-name>
<servlet-name> Action </ servlet-name>
</ Filter-mapping>
4. Followed by the writing of a Converter in storage before calling encode (), to be called the decode () ok. Below is a simple example:
(Public class Converter
Public Converter () (
)
Public static String enCode (String str) (
[] Byte temp;
Temp = str.getBytes ();
Try (
/ / System.out.println ( "in before convert:" + str);
Str = new String (temp, "ISO-8859-1");
/ / System.out.println ( "in after convert:" + str);
)
Catch (Exception e) (
System.err.println ( "convert error:" + e);
)
Return str;
)
Public static String deCode (String str) (
[] Byte temp;
Try (
/ / System.out.println ( "out before convert:" + str);
Temp = str.getBytes ( "ISO-8859-1");
Str = new String (temp, "GBK");
/ / System.out.println ( "out after convert:" + str);
)
Catch (Exception e) (
System.err.println ( "convert error:" + e);
)
Return str;
)
)
5. Should all OK too, so I settled on the struts of the Chinese and international issues. Younger brother of a rookie, if wrong please master Comments?
