Question

我在jsf inputText中遇到了奇怪的问题。在浏览器上，它在输入框中显示了管理bean名称和变量名称（即＃{loginModel.userName}）。以下是我的jsf页面代码

<body>
<f:view>
    <h:form>
        <h:outputLabel value="Username"></h:outputLabel>
        <h:inputText value="#{loginModel.userName}"></h:inputText>
        <h:outputLabel value="Password"></h:outputLabel>
        <h:inputSecret value="#{loginModel.password}"></h:inputSecret>
        <h:commandButton value="Submit" action="#{loginModel.process}" ></h:commandButton>
    </h:form>
</f:view>
</body>

我的管理bean代码是

public class LoginModel {

    private String userName;
    private String password;
    public String getPassword() {
        return password;
    }
    public void setPassword(String password) {
        this.password = password;
    }
    public String getUserName() {
        return userName;
    }
    public void setUserName(String userName) {
        this.userName = userName;
    }

    public String process(){

        System.out.println("Logged in user id is "+this.getUserName()+" and password to access is "+this.getPassword());
        return "Submit";
    }

}

和我的faces-config.xml文件

<managed-bean>
        <managed-bean-name>loginModel</managed-bean-name>
        <managed-bean-class>net.varun.dto.LoginModel</managed-bean-class>
        <managed-bean-scope>session</managed-bean-scope>
</managed-bean>

以下是我在浏览器上的输出以及当我点击提交按钮

时我变为空

尝试以下代码：

更改你的h：commandButton for primefaces进程，partialSubmit和ajax

<body>
<f:view>
    <h:form>
        <h:outputLabel value="Username"></h:outputLabel>
        <h:inputText value="#{loginModel.userName}"></h:inputText>
        <h:outputLabel value="Password"></h:outputLabel>
        <h:inputSecret value="#{loginModel.password}"></h:inputSecret>
        <p:commandButton value="Submit" action="#{loginModel.process}" process="@form" partialSubmit="true" ajax="true" />
    </h:form>
</f:view>
</body>

因此，您可以在流程方法中放置断点以查看更新值。
