有人说,乱码问题一直跟中国的程序员特别有缘,真是再同意不过了,不管是Struts,JSF,JSP,还是MySQL,Tomcat,全都或多或少有乱码的问题。
一般的做法有用Filter:
< filter >
< filter-name > Set Character Encoding </ filter-name >
< filter-class > org.springframework.web.filter.CharacterEncodingFilter </ filter-class >
< init-param >
< param-name > encoding </ param-name >
< param-value > GBK </ param-value >
</ init-param >
< init-param >
< param-name > ignore </ param-name >
< param-value > true </ param-value >
</ init-param >
</ filter >
< filter-mapping >
< filter-name > Set Character Encoding </ filter-name >
< url-pattern > *.do </ url-pattern >
</ filter-mapping >
< filter-mapping >
< filter-name > Set Character Encoding </ filter-name >
< url-pattern > *.jsp </ url-pattern >
</ filter-mapping >
< filter-mapping >
< filter-name > Set Character Encoding </ filter-name >
< url-pattern > *.html </ url-pattern >
</ filter-mapping >
< filter-mapping >
< filter-name > Set Character Encoding </ filter-name >
< url-pattern > *.htm </ url-pattern >
</ filter-mapping >
的,有用
<% request.setCharacterEncoding( " GBK " ); %>
的,还有用
<% @ page contentType = " text/html; charset=GBK " pageEncoding = " GBK " %>
<meta http-equiv="content-type" content="text/html; charset=GBK">
的,还可以用
<% String name = new String(request.getParameter( " name " ).getBytes( " 8859_1 " ), " GB2312 " ); %>
昨天就在做项目的过程中,发现用URL传request参数的时候,在第二个页面上得到乱码的问题。把上面几种方法都试了一下还是不行。仔细追踪了一下,发现在页面的源代码上中文是正常的,一直到URL还是中文正常,可是在后台的Action里面log出来就成了乱码了,于是猜想是在request封装的过程中把中文变成乱码了,以致于后台直接就是取到的乱码。在后台Action中Set入中文,页面上正常显示,说明Struts的中文已经不存在问题。剩下的,应该就只有doGet和doPost方法的问题了。找了一下tomcat的配置文件,发现只要在server.xml中:
<!-- Define a non-SSL HTTP/1.1 Connector on port 8080 -->
< Connector port ="8080" maxHttpHeaderSize ="8192"
maxThreads ="150" minSpareThreads ="25" maxSpareThreads ="75"
enableLookups ="false" redirectPort ="8443" acceptCount ="100"
connectionTimeout ="20000" disableUploadTimeout ="true" />
<!-- Note : To disable connection timeouts, set connectionTimeout value
to 0 -->
改为
<!-- Define a non-SSL HTTP/1.1 Connector on port 8080 -->
< Connector port ="8080" maxHttpHeaderSize ="8192"
maxThreads ="150" minSpareThreads ="25" maxSpareThreads ="75"
enableLookups ="false" redirectPort ="8443" acceptCount ="100"
connectionTimeout ="20000" disableUploadTimeout ="true" URIEncoding ="GBK"/>
<!-- Note : To disable connection timeouts, set connectionTimeout value
to 0 -->
就是加上URIEncoding="GBK"就万事大吉了。
再加上一条:
<session-factory>
<property name="hibernate.connection.url">jdbc:jtds:sqlserver://192.168.0.3:1433;DatabaseName=HomeConsume;charset=GBK</property>
<property name="hibernate.cglib.use_reflection_optimizer">true</property>
<property name="hibernate.connection.password">sju</property>
<property name="hibernate.connection.username">sa</property>
<property name="hibernate.connection.driver_class">net.sourceforge.jtds.jdbc.Driver</property>
<property name="hibernate.dialect">org.hibernate.dialect.SQLServerDialect</property>
<mapping resource="net/magicyang/homeconsume/pojo/Test.hbm.xml" />
<mapping resource="net/magicyang/homeconsume/pojo/Consumeinfo.hbm.xml" />
<mapping resource="net/magicyang/homeconsume/pojo/Consumetype.hbm.xml" />
</session-factory>
至此,应该再困难的乱码问题都解决了吧。就是要在页面上、数据库中、request里、doGet、doPost方法里面都是中文!看你还有什么地方躲??
