想做忘記密碼功能，但老是被shiro攔截，沒登錄的請求都跳回登錄頁面這是獲取驗證碼的ajax function getYZM() {          $.ajax({                  url:'user/forgetPwdYz.do',                  type:"POST",                async: false,                 success: function(data){                   alert("成功");                    alert(data);                },                  error:function(data){                       alert("失敗");                     }                  })                          }     這是shiro的配置<!-- Shiro Filter -->     <bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean">         <property name="securityManager" ref="securityManager" />               ...         <property name="filterChainDefinitions">             <value>             //開放user請求，還是一直在登錄頁面             /user/*.do                    = anon             /userYz.jsp/**                = anon                             /**                            = authc            </value>         </property>     </bean>應該還需要改哪里？
