使用Struts2 的result 传递参数

1.当使用type=“redirectAction” 或type=“redirect”提交到一个action并且需要传递一个参数时。这里是有区别的:
使用type=“redirectAction”时,结果就只能写Action的配置名,不能带有后缀:“.action”2.在Action中定义:
private User user;user有get/set方法。EL取值:
${user.username}struts2取值:
<s:property value="user.username" /> //从ValueStack中取值

<s:property value="#user.username" /> //从Request中取值
Map sessionMap = ActionContext.getContext().getSession();
??????????? sessionMap.put("qi", qi);
public class LoginAction extends ActionSupport {
?private User user;
?
?//用于保存请求重定向到的action的名字
?private String nextAction;
?public User getUser() {
??return user;
?}
?public void setUser(User user) {
??this.user = user;
?}
?public String getNextAction() {
??return nextAction;
?}
?public void setNextAction(String nextAction) {
??this.nextAction = nextAction;
?}
?@Override
?public String execute() throws Exception {
??System.out.println("***************** "+user.isManager());
??//如何把user的manager传入的字符转换成boolean类型?
??if(user.isManager())
???nextAction="manager";
??else
???nextAction="employee";
??
??return SUCCESS;
?}
}
<action name="login"
???class="act.LoginAction">
???<result type="redirectAction">${nextAction}?name=${user.name}</result>
???<!-- LoginAction里的属性值name传到nextAction ,传递中文出现乱码-->
???</action>


<action name="employee"
???class="act.EmployeeAction">
???<result>/result.jsp</result>
???</action>
<table border="1">
??? ?<s:form action="/loginns/login.action">
???? ?<tr>
???? ??<td><s:textfield name="user.name" label="用户名" cssStyle="width:120px;"></s:textfield></td>
???? ?</tr>
???? ?<tr>
???? ??<td><s:password name="user.password" label="密码" cssStyle="width:120px;"></s:password></td>
???? ?</tr>
???? ?<tr><!-- 传入的值如果不是true,其它的都转换成false -->
???? ??<td><s:radio name="user.manager"? value="false" list="#{true:'是',false:'否'}" label="是否管理员"></s:radio></td>
???? ?</tr>
???? ?<tr>
???? ??<td align="center"><s:submit value="登陆"></s:submit></td>
???? ?</tr>
??? ?</s:form>
??? </table>
${param.name }(el)美元符号是El表达式
??? <s:property value="#parameters.name"/>(ognl)这个是OGNL来获取值
