Answer 1

1.action没配好
2.action配好了，但没编译
3.action里确实没有定义你调用的方法

Answer 2

谢谢二位
回1楼，我感觉这几个都没有问题啊
配置文件里的
<package name="role" extends="default" namespace="/role">
        <!-- Default interceptor stack. -->
        <default-interceptor-ref name="crudStack" />        <action name="list" class="roleAction" method="list">
            <result name="success">/WEB-INF/jsp/juese.jsp
            </result>
        </action>        <action name="edit-*" class="roleAction" method="edit">
            <param name="roleId">{1}</param>
            <result>/WEB-INF/jsp/updateRole.jsp
            </result>
        </action>
        
        <action name="edit" class="roleAction" method="edit">
            <result>/WEB-INF/jsp/updateRole.jsp
            </result>
        </action>        <action name="add" class="roleAction" method="add">
            <result type="redirect">list.action</result>
        </action>
        <action name="save_role" class="roleAction" method="save_role">
            <result name="input">/WEB-INF/jsp/updateRole.jsp
            </result>
            <result type="redirect">list.action</result>
        </action>
        <action name="delete-*" class="roleAction" method="delete">
            <param name="roleId">{1}</param>
            <result type="redirect">list.action</result>
        </action>
    </package>
action里的删除
  public String delete() throws Exception {
     if (roleId != null)
            roleManager.deleteRole(roleId);
        return SUCCESS;
    }
回2楼
我把方法名改了也是出这个错误啊

你的action跳转的时候调用的方法在配置文件里面没关联好！
或者是你跳转的url写错了和配置文件的不对应！
