我在struts.xml.

    <!-- Configuration for the default package. -->
    <package name="default"  extends="struts-default">
        <interceptors>
            <!-- Interceptor to handle allowing only admins to certain actions -->
            <interceptor name="adminOnly" class="adminInterceptor"/>
            <!-- Interceptor to handle accessDenied exceptions thrown from service/model layer called from within actions -->
            <interceptor name="accessDenied" class="accessDeniedInterceptor"/>
            <!-- Copied from struts-default.xml and changed validation exclude methods -->
            <interceptor-stack name="defaultStack">
                <interceptor-ref name="accessDenied"/>
                <interceptor-ref name="exception"/>
                <interceptor-ref name="alias"/>
                <interceptor-ref name="servletConfig"/>
                <interceptor-ref name="prepare"/>
                <interceptor-ref name="i18n"/>
                <interceptor-ref name="chain"/>
                <interceptor-ref name="debugging"/>
                <interceptor-ref name="profiling"/>
                <interceptor-ref name="scopedModelDriven"/>
                <interceptor-ref name="modelDriven"/>
                <interceptor-ref name="fileUpload"/>
                <interceptor-ref name="checkbox"/>
                <interceptor-ref name="staticParams"/>
                <interceptor-ref name="params">
                    <param name="excludeParams">dojo\..*</param>
                </interceptor-ref>
                <interceptor-ref name="conversionError"/>
                <interceptor-ref name="validation">
                    <param name="excludeMethods">cancel,execute,delete,edit,list</param>
                </interceptor-ref>
                <interceptor-ref name="workflow">
                    <param name="excludeMethods">input,back,browse,cancel</param>
                </interceptor-ref>
            </interceptor-stack>
            <interceptor-stack name="fileUploadStack">
                <interceptor-ref name="fileUpload"/>
                <interceptor-ref name="defaultStack"/>
            </interceptor-stack>
            <interceptor-stack name="adminCheck">
                <interceptor-ref name="defaultStack"/>
                <interceptor-ref name="adminOnly"/>
            </interceptor-stack>
        </interceptors>



<action name="editUser" class="userAction" method="edit">
            <interceptor-ref name="adminCheck"/>
            <result name="success">/WEB-INF/pages/userForm.jsp</result>
            <result name="input">/WEB-INF/pages/admin/userList.jsp</result>
            
        </action>
        
         <action name="cancelUser" class="userAction" method="cancel">     
         
         <result name="cancel" type="redirectAction">admin/users</result>      
         <!--    <result name="cancel">/WEB-INF/pages/admin/userList.jsp</result> -->          
         </action>

<action name="saveUser" class="userAction" method="save">
         <!--    <result name="cancel" type="redirectAction">admin/users</result>  -->
            <result name="input">/WEB-INF/pages/userForm.jsp</result>
            <result name="success" type="redirectAction">admin/users</result>
        </action>

然后我有我提到的 JSP 页面

<s:form name="userForm" action="saveUser" method="post" validate="true" cssClass="well" autocomplete="off">

表单有 3 个提交按钮。

<div id="actions" class="form-group">
            <s:submit type="button" cssClass="btn btn-primary" method="save" key="button.save" theme="simple">
                <i class="icon-ok icon-white"></i>
                <fmt:message key="button.save"/>
            </s:submit>
            <c:if test="${param.from == 'list' and not empty user.id}">
                <s:submit type="button" cssClass="btn btn-danger" method="delete" key="button.delete"
                          onclick="return confirmMessage(msgDelConfirm)" theme="simple">
                    <i class="icon-trash"></i>
                    <fmt:message key="button.delete"/>
                </s:submit>
            </c:if>
            <s:submit type="button" cssClass="btn btn-default" method="cancel" action="cancelUser"  key="button.cancel" theme="simple">
                <i class="icon-remove"></i>
                <fmt:message key="button.cancel"/>
            </s:submit>
        </div>
        </s:form>

我的动作类有这些方法：

public String execute() {
    return SUCCESS;
}


public String cancel() {
    if (!"list".equals(from)) {
        return "home";
    }
    return "cancel";
}


public String save() throws Exception {

    Integer originalVersion = user.getVersion();

    boolean isNew = ("".equals(getRequest().getParameter("user.version")));
    // only attempt to change roles if user is admin
    // for other users, prepare() method will handle populating
    if (getRequest().isUserInRole(Constants.ADMIN_ROLE)) {
        user.getRoles().clear(); // APF-788: Removing roles from user
                                    // doesn't work
        String[] userRoles = getRequest().getParameterValues("userRoles");

        for (int i = 0; userRoles != null && i < userRoles.length; i++) {
            String roleName = userRoles[i];
            try {
                user.addRole(roleManager.getRole(roleName));
            } catch (DataIntegrityViolationException e) {
                return showUserExistsException(originalVersion);
            }
        }

单击取消按钮也会触发验证。有没有办法阻止点击取消触发验证？

更改代码：

<!-- Configuration for the default package. -->
    <package name="default"  extends="struts-default">
        <interceptors>
            <!-- Interceptor to handle allowing only admins to certain actions -->
            <interceptor name="adminOnly" class="adminInterceptor"/>
            <!-- Interceptor to handle accessDenied exceptions thrown from service/model layer called from within actions -->
            <interceptor name="accessDenied" class="accessDeniedInterceptor"/>
            <!-- Copied from struts-default.xml and changed validation exclude methods -->
            <interceptor-stack name="myDefaultStack">
                <interceptor-ref name="accessDenied"/>
                <interceptor-ref name="exception"/>
                <interceptor-ref name="alias"/>
                <interceptor-ref name="servletConfig"/>

                <interceptor-ref name="myDefaultStack"/>
            </interceptor-stack>
            
          <!--   <default-interceptor-ref name="myDefaultStack"/> -->
          
            <interceptor-stack name="adminCheck">
                <interceptor-ref name="myDefaultStack"/>
                <interceptor-ref name="adminOnly"/>
            </interceptor-stack>                      
        </interceptors>
            
            
         <default-interceptor-ref name="myDefaultStack"/>

我已经完成了配置。我在问它有什么问题。可能我的问题标题是错误的。但我想问的是为什么它对我不起作用。我的代码有什么问题。

在您的代码中，您在标签上使用method了属性。s:submit默认情况下，此属性不再有效，因为DMI（动态方法调用）已禁用。xml 配置中有一个设置常量，您可以更改它以启用此功能。但是，如果您对方法没有隐含的安全性，您可能会遇到其他安全问题。

<constant name="struts.enable.DynamicMethodInvocation" value="true"/>
<constant name="struts.mapper.action.prefix.enabled" value="false"/>

并使用

<s:submit type="button" cssClass="btn btn-default" method="cancel"
  key="button.cancel" theme="simple">

另一种方法是将属性更改method为action并使用

<constant name="struts.enable.DynamicMethodInvocation" value="false"/>
<constant name="struts.mapper.action.prefix.enabled" value="true"/>

并使用

<s:submit type="button" cssClass="btn btn-default" action="cancelUser"
  key="button.cancel" theme="simple">

您不能同时使用属性method和标签action。s:submit如果上面的两个设置都是false绑定到s:form标签的动作将执行。这就是发生验证的原因。
