Attribute "short-circuit" must be declared for element type "validator".

使用struts2验证是报错：

引用

Attribute "short-circuit" must be declared for element type "validator".

解决办法：
将<actionClass>-<actionAlias>-validation.xml的头：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE validators PUBLIC 
          "-//OpenSymphony Group//XWork Validator 1.0//EN" 
          "http://www.opensymphony.com/xwork/xwork-validator-1.0.2.dtd" >

改为：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE validators PUBLIC 
          "-//OpenSymphony Group//XWork Validator 1.0.2//EN" 
          "http://www.opensymphony.com/xwork/xwork-validator-1.0.2.dtd" >
