struts2--国际化

1. 创建资源文件,放在action包里:App_en_US.properties, App_zh_CN.properties.

　在properties界面用add的方式添加变量,添加完成后, 打开source如下:

login.username=username:
login.password=password:
login.email=email
login.submit=submit
login.username.isnull=username is null
login.password.isnull=password is null
login.email.isnull=email is null
login.password.lengtherror=password length must be 4~6
login.email.formaterror=email format is error
login.field.isnull={0} is null
label.username=username
label.password=password
label.email=email

login.username=u7528u6237u540D:
login.password=u5BC6u7801:
login.email=u7535u5B50u90AEu4EF6
login.submit=u786Eu5B9A
login.username.isnull=u7528u6237u540Du4E0Du80FDu4E3Au7A7A
login.password.isnull=u5BC6u7801u4E0Du80FDu4E3Au7A7A
login.email.isnull=u7535u5B50u90AEu7BB1u4E0Du80FDu4E3Au7A7A
login.password.lengtherror=u5BC6u7801u5FC5u987B4~6u4F4D
login.email.formaterror=u7535u5B50u90AEu4EF6u683Cu5F0Fu4E0Du6B63u786E
login.field.isnull={0}u4E0Du80FDu4E3Au7A7A
label.username=u7528u6237u540D
label.password=u5BC6u7801
label.email=u7535u5B50u90AEu7BB1

　　

2. struts.xml加载属性文件, 配置在所有包最上面 struts里面, 添加下面这句话:

 <constant name="struts.custom.i18n.resources" value="App"></constant>

3. login.jsp页面读取资源文件:

//选择语言
<a href="<%=path%>/language.action?request_locale=en_US">英文</a>|<a href="<%=path%>/language.action?request_locale=zh_CN">中文</a>

<s:property value="getText('label.username')"/>
<s:property value="getText('label.password')"/>
<s:property value="getText('label.email')"/>
<br><input type="button" value="<s:property value="getText('login.submit')"/>" onclick="javascript:document.loginForm.action='<%=path%>/user/login1.action';document.loginForm.submit();"/>

4. struts.xml里在default包里添加:

 <action name="language">
    	<result>/login.jsp</result>
 </action>

　　

5.validation.xml里加载属性信息:

validation.xml(UsersAction2-validationl.xml)里的出错信息也可以用国际化文件:

${getText("login.field.isnull",{getText("label.username")})} 传递参数, login.field.isnull里有{0}
