Struts2异常处理国际化
功能：利用struts2内建的拦截器exception来处理异常信息的国际化。
部署方法：
1.struts.xml中添加国际化支持，设置资源文件名：
<struts>
<constant name="struts.custom.i18n.resources"value="exceptionMassage ">
</constant>
<constant name="struts.locale" value="en_utf-8" />
<global-results>
<result name="operationException">/WEBINF/jsp/common/operationException.jsp
</result>
</global-results>
<global-exception-mappings>
<exception-mapping result="operationException"
exception="cn.com.base.exception.OperationException">
</exception-mapping>
</global-exception-mappings>
</struts>
2.资源文件
exceptionMessages_en_US.properties
exceptionMessages_zh_CN.properties:
user_001:请输入正确的客户卡号！
3.建立异常常量类：ExceptionConstants.java
public class ExceptionConstants {
/**
* 业务异常关键字 user_001 --异常信息:请输入正确的客户卡号
*/
public static final String EXCEPTION_OPERATION_USER_CUS = "user_001";
4.建立异常类基类：BaseException.java
public class BaseException extends Exception {
/**
* 类序列化ID
*/
private static final long serialVersionUID = -5246579929018578466L;
/**
* 国际化信息key
*/
private String errorCode;
public BaseException() {
super();
}
public BaseException(final String errorCode) {
this.errorCode = errorCode;
}
public String getErrorCode() {
return errorCode;
}
public void setErrorCode(String errorCode) {
this.errorCode = errorCode;
}
}
5.建立异常类：OperationException.java
public class OperationException extends BaseException {
/**
* 类序列化ID
*/
private static final long serialVersionUID = -2657816827277800681L;
public OperationException() {
super();
}
public OperationException(final String errorCode) {
super(errorCode);
}
}
5.action类抛出异常
public String save(){
………………
if(BlankUtil.isBlank(user.getCardid())){
throw new OperationException(
ExceptionConstants.EXCEPTION_OPERATION_USER_CUS);
}
}
6.异常跳转页面：operationException.jsp
<body>
操作提示：<s:property value="%{getText(exception.errorCode)}"/>
</body>
