java - 使用validate()方法时Struts表单自动提交

转载 作者：行者123 更新时间：2023-12-01 05:41:09 24 4

我使用的是struts 1.2。我的 struts 流程工作正常，但是当我使用操作表单的 validate() 方法进行验证时。我的表格会自动提交。并调用此验证方法。

我不确定这是 struts 的正常行为还是我的应用程序中缺少某些配置。

请帮我理解一下。以下是配置和代码

<action path="/Postaddd" 
            type="bseller.postadd.PostaddAction" 
            parameter="dispatch"
            scope="request"
            validate="true"
            name="PostadddForm">
        <forward name="posterror" path="ordererror.page"/>
        <forward name="successPost" path="bseller.successPost.page"/>  

    </action>       public ActionErrors validate(ActionMapping mapping, HttpServletRequest request) 
    {


        Logger  log= Logger.getLogger("BSELLER_APPLICATION");
        log.info("validate method called");
        ActionErrors errors = new ActionErrors();

          log.info("Email Id: " + getEmailid()); 
          if(!Validation.isValidEmailAddress(getEmailid()))
                  {
              errors.add("emailid", new ActionMessage("prompt.email.error"));
                  }
          if(!Validation.isPhoneNumberValid(getMobile()))
          {
              errors.add("mobile", new ActionMessage("prompt.contactno.error"));
          }

          if(!Validation.isNumeric(getPrice()))
          {
              errors.add("price", new ActionMessage("prompt.price.error"));
          }


        return errors;
    }

最佳答案

actionform的validate方法总是在表单提交时被调用。你不能手动调用它，除非你用自己的方式重新实现struts。如果您希望一个方法执行与 validate 方法相同的工作，请将 validate 方法的代码移动到另一个方法中并在 validate 方法中调用它。我不完全明白你想做什么，所以请说得更具体一些。

关于java - 使用validate()方法时Struts表单自动提交，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/7138578/
