将文本字段值从jsf页面传递到托管bean [英] Passing text field values from jsf page to managed bean

问题描述

我有一个JSF表单，当单击操作按钮时，该表单将调用托管bean的方法.该方法已成功调用，但是现在我想从Bean访问在form字段中输入的值.这是我的代码.

I have a JSF form which calls a method of a managed bean when the action button is clicked. The method is successfully called, but now I would like to access the values entered in the form field from the bean. Here is my code.

视图:

<h:form class="form-horizontal" action= "#{hello_World.message}" method="post" id="formId">      
 <div class="control-group">
  <label class="control-label" for="inputEmail">First Name</label>
  <div class="controls">
  <h:inputText id="firstname" placeholder="First Name" value="#{submission.firstName> </h:inputText>
  </div> 

  <div class="control-group">
   <label class="control-Label">Address</label>
   <div class="controls">
   <input type="text" placeholder="Address" />
   </div>
   </div>
    <h:commandButton value="click" action="#{submission.submitted}"/>       
</h:form>

模型:

@ManagedBean(name="submission", eager=true)
public class MainClass {    
String firstName = "Pranbsh";
public MainClass(){
    System.out.println("Helloworld started from managed bean");
}
private String getFirstName(){
    return firstName;
}
public void submitted(){
    System.out.println("Bean executed");
    System.out.println("First name is ") ;      
  }
}

推荐答案

使用getter和setter可以像这样从xhtml获取值

Use getter and setter to get the values from the xhtml like this

JSF form

<h:form class="form-horizontal" action= "#{hello_World.message}" method="post" id="formId">      
  <div class="control-group">
  <label class="control-label" for="inputEmail">First Name</label>
  <div class="controls">
  <h:inputText id="firstname" placeholder="First Name" value="#{submission.firstName> </h:inputText>
  </div> 

   <div class="control-group">
   <label class="control-Label">Address</label>
   <div class="controls">
   <input type="text" placeholder="Address" />
   </div>
   </div>
    <h:commandButton value="click" action="#{submission.submitted}"/>       
</h:form>

Managed Bean

  public class Form {
    String firstName ="Pranish";

    public String getFirstName(){
        return firstName;
    }

    public void setFirstName(String firstName){
        this.firstName = firstName;
    }

    public void submitted(){
        System.out.println("Bean executed");
        setFirstName(firstName);
        System.out.println("First Name : " + getFirstName());   
    }

}
