我正在尝试用JSF验证两个密码字段,但直到现在还没有好处,我在google上搜索它,但一切都是关于JSF 1.2而且非常令人困惑,我正在使用JSF 2.0.

这就是我到目前为止所做的事情:

        <h:outputLabel for="password" value="Password:" />
        <h:inputSecret id="password"  value="#{register.user.password}"  >  
            <f:ajax    event="blur"   listener="#{register.validatePassword}" render="m_password" />
        </h:inputSecret>
        <rich:message id="m_password" for="password"/>

        <h:outputLabel for="password_2" value="Password (again):" />
        <h:inputSecret id="password_2"  value="#{register.user.password_2}"  >  
            <f:ajax    event="blur"     listener="#{register.validatePassword}" />
        </h:inputSecret>

这就是我的控制器:

public void validatePassword() {
    FacesMessage message;

    if (!user.getPassword().equals(user.getPassword_2()) ){
        message = new FacesMessage(FacesMessage.SEVERITY_ERROR, null, "different password");
    }else{
        message = new FacesMessage(FacesMessage.SEVERITY_INFO, null, "ok");
    }

    FacesContext.getCurrentInstance().addMessage("form:password", message);
}

伙计们好吗？
