}
用了struts的验证框架
UserRegsiterAction-validation.xml
<validators>
<field name="custorm">
<field-validator type="visitor">
<param name="context">user</param>
<param name="appendPrefix">true</param>
<message>用户的</message>
</field-validator>
</field>
</validators>
Custorm-user-validaton.xml
<validators>
 <field name="name">
 <field-validator type="requiredstring">
 <message>用户名不能为空</message>
</field-validator>
 </field>
 <field name="password" >
 <field-validator type="requiredstring">
 <message>密码不能为空</message>
 </field-validator>
 </field> 
 </validators>
当我点击注册时 就出现了这个情况 按理说应该是xx不能为空之类的 是什么原因呢？

Answer 1

userRegisterAction  检查这个类在spring中的配置

Answer 2

struts.xml
<action name="UserRegisterAction" class="userRegisterAction">
<result>/success.jsp</result>
</action>
appligcationContext.xml
<bean name="userRegisterAction" class="action.UserRegisterAction" scope="prototype"> <property name="serviceDao" ref="serviceDao"/></bean>
没有什么问题

Answer 3

你的struts和spring没有整合好吧

Answer 4

<action name="UserRegisterAction" class="userRegisterAction">
<result>/success.jsp</result>
</action>是不是你写反了啊？？
<action name="userRegisterAction" class="UserRegisterAction">
<result>/success.jsp</result>
</action>

Answer 5

注意大小写，页面上的action跟struts的action一致，struts的class跟spring的bean一致

Answer 6

<action   name= "UserRegisterAction "   class= "userRegisterAction "> 
Are u sure that?
写反了吧哥们！～～你的类名是小写的？？？？？

Answer 7

的确没错呀 <s:form action="UserRegisterAction"><action name="UserRegisterAction" class="userRegisterAction">
<bean name="userRegisterAction" class="action.UserRegisterAction" scope="prototype">

Answer 8

楼主排查以下二个可能会出现问题的地方：
1、struts配置文件需要加入<constant name="struts.objectFactory" value="spring"/>
2、web.xml需要启动spring <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

Answer 9

 WEB.XML:
<filter>
   <filter-name>struts2</filter-name>
   <filter-class>
   org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
   </filter-class>
  </filter>
  <filter-mapping>
   <filter-name>struts2</filter-name>
   <url-pattern>/*</url-pattern>
  </filter-mapping>
  <context-param>
 <param-name>contextConfigLocation</param-name>
 <param-value>/WEB-INF/applicationContext.xml</param-value>
 </context-param>
 <listener>    
        <listener-class >    
            org.springframework.web.context.ContextLoaderListener    
</listener-class>
    </listener>
11楼得我看了 都有

Answer 10

<action name="UserRegisterAction" class="userRegisterAction">
<result name="success">/success.jsp</result>
</action>加上这个属性试下吧，我查了下代码好像与spring集成时需要这个

Answer 11

userRegisterAction 的类名没写对

Answer 12

应该是找到根本原因了
你的validation验证没有通过，返回input它却没有找到相应的input result 会偿试着用ACTION的class去新建一个对象所以报错了，就是你没有入口路径。。

Answer 13

问题解决了 15楼真是一语中的 的确 我没有配置input 的结果 散分了。。

Answer 14

<s:form action="UserRegisterAction">
  <s:textfield name="custorm.name" label="姓名" required="true"/>
  <s:password name="custorm.password" label="密码" required="true"/>
  <s:submit value="注册"/>
  <s:reset value="重填"/>
  </s:form>改为
<s:form action="/UserRegisterAction">
  <s:textfield name="custorm.name" label="姓名" required="true"/>
  <s:password name="custorm.password" label="密码" required="true"/>
  <s:submit value="注册"/>
  <s:reset value="重填"/>
  </s:form>

Answer 15

15楼的高手，你可不可以说详细一点啊，我就没有validation验证啊 

Answer 16

咋一看,还以为没有这个类呢,但是命名存在,其实真正原因是没有合适的result name,这错误误导得可真离谱啊 忘记添加对应的result name了。当添加完毕，一切欧了。
 

Answer 17

补充一下，Action页面如果返回的是大写“SUCCESS”或者“INPUT”，在Struts.xml中的result的name属性一定是大写的。如果小写就配置小写。如果不匹配也会导致上面的错误发生。这是我今天刚刚遇到的错误，提出来与大家分享。

Answer 18

15楼的高手，你可不可以说详细一点啊，我就没有validation验证啊  

Answer 19

我的没用struts标签也这样
好像还有其他有问题，请高手们赐教

Answer 20

我发现问题了
1，隐藏域  value=空
2，上传的文件时 忘了加enctype="multipart/form-data"看看说不定有帮助
