Webx之表单验证

 

  引入服务器端表单验证service，是通过在webx.xml中通过服务引入的方式完成的。例如，在user相关信息的表单验证的产生过程是这样的：webx-user.xml通过 <beans:import resource="user/form.xml" />引入form,xml表单验证配置，在form.xml中，通过services:form开始了表单的验证工作。 

•  开始配置表单验证服务。
• 每个表单验证服务可包含多个groups。
• 每个group可包含多个fields。
• 每个field可包含多个validators。  

user/form.xml具体配置如下：
