本实例主要是功能是实现Struts2 国际化,防止刷新得利提交表单,利用struts2的验证机制验证字符输入的合法性,邮箱输入的正确性。

本实例用两个页面(create.jsp,createResult.jsp),一个Action(CreateAction),一个验证文件(CreateAction-validation.xml),两个Struts2 国际化文件(message_en_US.properties,message_zh_CN.properties),还有一个struts.xml(必有的).创立用户成功之后,显现方才创立的信息,不成功则显现过错提示,过错提示运用了Struts2 国际化来显现,输入合法性就用了用struts2的验证机制验证.

1.CreateAction.java 
// ******************************************************************
package cn.struts2;


import java.util.Date;


import com.opensymphony.xwork2.ActionSupport;


public class CreateAction extends ActionSupport
{
 private String name ;
 private String password;
 private String repassword;
 private Date birthday;
 private Date registedDay;
 private int age;
 private String email;

 /**
 * @return the name
 */
 public String getName()
 {
 return name;
 }
 /**
 * @param name the name to set
 */
 public void setName(String name)
 {
 this.name = name;
 }
 /**
 * @return the password
 */
 public String getPassword()
 {
 return password;
 }
 /**
 * @param password the password to set
 */
 public void setPassword(String password)
 {
 this.password = password;
 }
 /**
 * @return the repassword
 */
 public String getRepassword()
 {
 return repassword;
 }
 /**
 * @param repassword the repassword to set

 public void setRepassword(String repassword)
 {
 this.repassword = repassword;

 /**

 {
 return email;
 }
 public void setEmail(String email)
 {
 this.email = email;
 }
 //****************************************

 public String execute()throws Exception
 {
 return SUCCESS;
 }

}


2.置大局Struts2 国际化文件(两个):

// message_en_US.properties ********************************************
create = Create Users Information
username.invalid = User Name Not Null!
password.invalid.null = Password Not Null!
password.invalid.too.short.or.long = Password should be between 6 and 10
submit = submit
//***********************************************************************
中文国际化
// message_zh_CN.properties ********************************************
create = \u521b\u5efa\u7528\u6237\u4fe1\u606f
username.invalid = \u7528\u6237\u540d\u4e0d\u80fd\u4e3a\u7a7a
password.invalid.null = \u5bc6\u7801\u4e0d\u80fd\u4e3a\u7a7a
password.invalid.too.short.or.long = \u5bc6\u7801\u957f\u5ea6\u5fc5\u987b\u57286\u523010\u4e4b\u95f4
submit =\u63d0\u4ea4


//***********************************************************************

留意:如(create = \u521b\u5efa\u7528\u6237\u4fe1\u606f)等号右边的一串乱码是中文字符对就的ASCII码值,假如你需求转化,能够翻开你的CMD(开端-->运转-->输入CMD即可),输入指令native2ascii,回车,将你的中文字符粘上,再回车就能够看到一串乱码了.再将其COPY到相应的方位即可.

文件的姓名不能乱取,XXX_en_US.properties,XXX_zh_CN.properties,XXX后边的姓名是固定的,而前面的XXX是依据你的struts.xml文件中的

 < CONSTANT name="struts.custom.i18n.resources" value="XXX">中的XXX而取的.本例的XXX便是message.


3.struts.xml 
// ************************************************************************
< ?xml version="1.0" encoding="UTF-8"?>
http://struts.apache.org/dtds/struts-2.0.dtd">



< STRUTS>
 < CONSTANT name="struts.custom.i18n.resources" value="message">< /CONSTANT>

 < PACKAGE name="struts2" extends="struts-default">


 < ACTION class=cn.struts2.CreateAction name="create">
 /createResult.jsp< /RESULT>
 < RESULT name="input">/create.jsp< /RESULT>



 < INTERCEPTOR-REF name="token">< /INTERCEPTOR-REF>
 < INTERCEPTOR-REF name="defaultStack">< /INTERCEPTOR-REF>
 /create.jsp 



 < /PACKAGE>


//************************************************************************


4.web.xml 
// ****************************************************************



 


 
< META content=no-cache http-equiv=pragma>
 
< META content=no-cache http-equiv=cache-control>
 
< META content=0 http-equiv=expires>
 
< META content=keyword1,keyword2,keyword3 http-equiv=keywords>
 
< META content="This is luanmad's JSP page " http-equiv=description>
 < !--

 -->


 


 

 < s:form method="post" action="create">
 < !-- 避免改写重复提交-->
 < s:token>< /s:token>


 < s:textfield name="name" label="User Name">< /s:textfield>
 < s:password name="password" label="Password">< /s:password>
 < s:textfield name="age" label="Age">< /s:textfield>
 < s:textfield name="birthday" label="Birthday">< /s:textfield>
 < s:textfield name="registedDay" label="RegistedDay">
 < s:textfield name="email" label="Email">
 < s:submit key="submit">< /s:submit>
 < s:reset label="reset">< /s:reset>


 


//*******************************************************************

6.验证文件(留意姓名要与你的Action姓名相同,后边再跟固定的(-validation.xml)如(CreateAction-validation.xml)

CreateAction-validation.xml:
// ****************************************************************************
< ?xml version="1.0" encoding="UTF-8"?>
http://www.opensymphony.com/xwork/xwork-validator-1.0.2.dtd">


< !-- 格局的写法能够参照XWork Validator 1.0.2.dtd -->
< !-- 参数设置参照xwork-2.0.5.jar 下的com.opensymphony.xwork2.validator.validators/default.xml -->
< VALIDATORS>


 < !--验证谁, 用谁来验证 -->
 < FIELD name="name">
 < FIELD-VALIDATOR type="requiredstring">
 < !--requiredstring对应的类的办法里的参数名trim 如public void setTrim(boolean trim)里的trim -->
 < PARAM name="trim">true< /PARAM>
 < !-- message key的key内容是I18N里(即baseName_zh_CN.properties和baseName_en_US.properties中)界说的字段名即等号在边的姓名如(username.invalid = 姓名不能为空)-->
 < /MESSAGE>
 < /FIELD-VALIDATOR>
 < /FIELD>

 < FIELD name="password">
 < FIELD-VALIDATOR type="requiredstring">
 < PARAM name="trim">true< /PARAM>
 < MESSAGE key="password.invalid.null">< /MESSAGE>
 < /FIELD-VALIDATOR>
 < /FIELD>
 < FIELD name="password">
 < FIELD-VALIDATOR type="stringlength">
 < PARAM name="minLength">6< /PARAM>
 < PARAM name="maxLength">16< /PARAM>
 < MESSAGE key="password.invalid.too.short.or.long">< /MESSAGE>
 < /FIELD-VALIDATOR>
 < /FIELD>

 < !-- 以下未做国际化 -->
 < FIELD name="age">
 < FIELD-VALIDATOR type="int">
 1< /PARAM>
 < PARAM name="max">150< /PARAM>
 < MESSAGE>age should be between ${min} and ${max}
 < /FIELD-VALIDATOR>
 < /FIELD>

 < FIELD name="birthday">
 < FIELD-VALIDATOR type="required">
 < MESSAGE>birthday not null!< /MESSAGE>
 < /FIELD-VALIDATOR>

 < FIELD-VALIDATOR type="date">
 < PARAM name="min">2000-01-01< /PARAM>
 < PARAM name="max">2008-01-01< /PARAM>
 < MESSAGE>birthday should be between ${min} and ${max}
 < /FIELD-VALIDATOR>


 < FIELD name="email">
 < FIELD-VALIDATOR type="email">
 < MESSAGE>email format error!
 < /FIELD-VALIDATOR>
 < /FIELD>
