??? ActionErrors中,ActionError對(duì)象中的參數(shù)為配置文件中配置的相應(yīng)的值,若配置文件

?*/
1.建立配置文件MyResource.property,例如放在com.gsww.property下.在此配置文件中設(shè)定所需要的對(duì)應(yīng)值,如:
???# Resources for parameter 'com.yourcompany.struts.ApplicationResources'
???# Project P/xioahu
???user.name=<b>userName {0} {1} is not valid user,please input again.</b>
???login.false=<b>userName or password is not right</b>???
2.在struts-config.xml中配置如下:
???<message-resources parameter="com.gsww.property.MyResource" />
3.應(yīng)用如下:
???ActionErrors errors = new ActionErrors();
???ActionError error = new ActionError("login.false");
???errors.add("loginFalse",error);
???saveErrors(request,errors):
4.JSP頁(yè)面中輸出錯(cuò)誤信息
???<html:errors property="loginFalse"/>
???<form-beans >
??? <!-- <form-bean name="loginForm" type="com.gsww.web.actionForm.LoginForm" /> -->
????<form-bean name="loginForm" type="org.apache.struts.action.DynaActionForm">
?????<form-property name="userName" type="java.lang.String"/>
?????<form-property name="password" type="java.lang.String"/>
????</form-bean>
???</form-beans>
2.Action中的應(yīng)用如下:
/**建立動(dòng)態(tài)表單對(duì)象,用于獲取表單數(shù)據(jù)*/
??DynaActionForm dynaform = (DynaActionForm)form;
??
/**用DynaActionForm.get("字段名")來(lái)獲取字段值*/
??System.out.print("userName="+dynaform.get("userName"));
<attribute name="Java2ClassLoadingCompliance">true</attribute>
<attribute name="UseJBossWebLoader">true</attribute>
但為什么配置文件好像還是不起作用?(配置文件無(wú)誤,已使用指定路徑的辦法測(cè)試過(guò),log4j.property默認(rèn)放在了SRC目錄下).
解決方法一是不用 Console 的 Appender, 或者改 jboss 的配置文件，在 jboss-service.xml 文件里 , 把
<mbean code="org.jboss.logging.Log4jService" name="jboss.system:type=Log4jService,service=Logging">
????????<attribute name="ConfigurationURL">resource:log4j.xml</attribute>
????????<attribute name="CatchSystemOut">false</attribute>
????????<attribute name="Log4jQuietMode">true</attribute>
</mbean> 。
我建議不用
Console
的
Appender
，當(dāng)然這是對(duì)
jboss3.2.x
是這樣，對(duì)于
jboss4.0.x
如果我們要用自己的
log4j
配置照上述改還是會(huì)有問(wèn)題，會(huì)有類似于
log4j:ERROR A "org.jboss.logging.util.OnlyOnceErrorHandler" object is not assignable to a "org.apache.log4j.spi.ErrorHandler" variable
的異常，解決方法是把
/server/default/jbossweb-tomcat55.sar/META-INF/jboss-service.xml
中的以下兩個(gè)熟悉改成
true
<attribute name="Java2ClassLoadingCompliance">true</attribute>
<attribute name="UseJBossWebLoader">true</attribute>
????try?{
????????????response.setContentType("text/html;charset=UTF-8");
????????????response.getWriter().write(text);
????}?catch?(IOException?e)?{
????????????log.error(e);
????}
????return?null;
}
?????????????????? or
?return?new?ActionForward("/foo/bar.jsp",true);
???
第一種
是appfuse里使用的，定義DynaValidatorForm里，內(nèi)嵌一個(gè)pojo屬性.
<form-bean?name="userForm"?type="org.apache.struts.validator.DynaValidatorForm">
????????????<form-property?name="user"?type="org.appfuse.model.User"/>
form-bean>
?
//
取得
form?DynaActionForm?userForm?=?(DynaActionForm)?form;
User?user?=?(User)?userForm.get("user");
//設(shè)置
form
userForm.set("user",user);
???
??? 第二種是用BeanValidatorForm，直接把Pojo作FormBean，無(wú)需繼承于FormBean接口。
?<form-bean?name="userForm"?type="org.springside.helloworld.domain.User"/>
?
//
取得
form?Bean
ValidatorForm?userForm?=?(BeanValidatorForm)?form;User?user?=?(User)?userForm.getInstance();
//設(shè)置
form
BeanUtils.copyProperties(userForm,?user);
<action?path="/admin/*"?name="{1}Form"?parameter="method"?scope="request"?validate="false">
????????????<forward?name="list"?path="/WEB-INF/pages/admin/{1}List.jsp"/>
????????????<forward?name="edit"?path="/WEB-INF/pages/admin/{1}Form.jsp"/>
????????????<forward?name="success"?path="/admin/{1}.do?method=list"?redirect="true"/>
action>
<action?path="/admin/user"?name="userForm"?scope="request"?parameter="method"?validate="false">
????<forward?name="list"?path="/admin/userList.jsp"/>
action>
???
其中parameter="method" 設(shè)置了用來(lái)指定響應(yīng)方法名的url參數(shù)名為method，即/admin/user.do?method=list 將調(diào)用UserAction的public ActionForward list(....)?函數(shù)。???
