参考

[Since Struts 1.2.0] You can force the clientside Javascript validation to check all constraints, instead of stopping at the first error. By setting a new property, stopOnFirstError, on the Validator PlugIn to false. 

Here's a sample configuration block that you could use in your Struts configuration file: 



  <plug-in className="org.apache.struts.validator.ValidatorPlugIn">
  <set-property property="pathnames"
   value="/WEB-INF/validator-rules.xml,/WEB-INF/validations.xml"/>
  <set-property property="stopOnFirstError" value="false"/>
  </plug-in>

将stopOnFirstError设为true即可

是不是struts2的啊,要是的话你的意思应该是一个字段添加了多个校验器,有错误的时候错误信息都显示了,不知道是不是这个意思,要是的话在你的校验器中(除了最后一个)添加一个短路校验器就可以了,比如<field-validator type="requiredstring" short-circuit="true">
