我是一个绝对的初学者。所以，如果我错过了显而易见的事情，请多多包涵。

我使用的环境：Spring Portlet MVC (3.0)、Liferay 6.0.6

我有一个控制器、一个表单 bean 和一个 JSP 页面。我可以使用以下代码成功提交表单并获取表单 bean。但是，在将 bean 转发到 JSP 之前，我被困在如何将一些值预加载到我的表单 bean 中。有人可以指出正确的方向：

我的控制器：

@ActionMapping(params = "spring_action=resetPasswordViewAction")
protected void resetPasswordAction(ActionRequest actionRequest, Map<String, Object> model, ActionResponse actionResponse, @RequestParam String customerId, @RequestParam String userName) {
    model.put("customerId", customerId);//Preload form bean value with this
    model.put("userName", userName);//Preload form bean value with this
    actionResponse.setRenderParameter("spring_render", "resetPasswordView");
}

@RenderMapping(params = "spring_render=resetPasswordView")
protected ModelAndView resetPasswordView(RenderRequest renderRequest, Map<String, Object> model) {
    return new ModelAndView("resetPassword", model);
}

@ActionMapping(params = "spring_action=resetPasswordUpdateAction")
protected void resetPasswordUpdateAction(ActionRequest actionRequest, Map<String, Object> model, ActionResponse actionResponse, final ResetPassword resetPasswordCriteria) {
    LOG.info(resetPasswordCriteria.toString());// Form values are retrieved successfully
    actionResponse.setRenderParameter("spring_render", "resetPasswordView");
}

@ModelAttribute("resetPasswordCriteria")
public ResetPassword getResetPasswordCriteria() {
    return new ResetPassword();
}

我的 JSP 页面：

<form:form id="resetPasswordForm" name="resetPasswordForm" commandName="resetPasswordCriteria" method="post" action="${resetPasswordUpdateActionURL}">

    <form:label path="customerId" /><!--Preload this field value-->
    <form:label path="userName" /><!--Preload this field value-->
    <form:password path="password" />
    <form:password path="confirmPassword" />
    <input type="submit" value="Submit" />

</form:form>

表单豆：

public class ResetPassword {
    private String customerId = "";
    private String userName = "";
    private String password = "";
    private String confirmPassword = "";
    //Getters Setters
}

In your rendering method resetPasswordView, place an object named resetPasswordCriteria (your commandName in jsp) of type ResetPassword to the model.
