我有这个表格,想要处理它:
<form id="myForm" class="form-horizontal" action="/user" method="post">
<fieldset>
<div class="control-group">
<!-- Text input-->
<label class="control-label" for="input01">Email:</label>
<div class="controls">
<input name="email" placeholder="email" class="input-xlarge" type="text"
value="<%=?????????">
</div>
</div>
<div class="control-group">
<!-- Text input-->
<label class="control-label" for="input01">Password:</label>
<div class="controls">
<input name="password" placeholder="password" class="input-xlarge" type="text"
value="<%=request.getParameter("password")%>">
</div>
</div>
</fieldset>
</form>
</div>
<div class="modal-footer">
<a href="#" class="btn" data-dismiss="modal">Close</a>
<input class="btn btn-primary" type='button' value='Save Changes'
onclick='document.forms["myForm"].submit();'>
</div>
</div>
但是,我有一个带有两个参数的bean方法,我尝试使用:
来处理这个问题public void insert(String email, String password) {
User entry = new User(email, password);
PersistenceManager pm = PMF.get().getPersistenceManager();
pm.makePersistent(entry);
}
我的问题是,如何正确地将Bean连接到使用两个参数的表单?
答案 0 :(得分:0)
您是否创建了bean java文件来连接这两个?功能bean文件由以下三部分组成:
在以下几行中,您将找到一个基于您在上面发布的表单的简单示例。记住System.out.println的旧技巧,检查你写的所有内容是否正确。
Bean文件,我们称之为userData.java
package blabla;
import java.io.Serializable;
public class UserData implements Serializable {
private String email;
private String password;
//1.Constructor
public UserData()
{
email="";
password="";
}
//2.Getters
public String getEmail(){
return email;
}
public String getPassword(){
return password;
}
//3.Setters - Caution: we use different variables here
public void setEmail(String eml)
{
this.email=eml;
}
public void setPassword(String pswd)
{
this.password=pswd;
} }
另一方面,.jsp文件应该像这样 的的index.jsp 强>
<%--Blablabla headers and stuff, I will only write the things needing to be added--%>
<jsp:useBean id="entry" class="packagePath.UserData" scope="application"/>
<%--For analytic info about the parameters of the jsp call above, check: http://www.javatpoint.com/jsp-useBean-action--%>
<jsp:setProperty name="entry" property="*"/>
<%--Code to invoke all the setters of the bean--%>
<p><jsp:getProperty name="entry" property="email"/></p>
<p><jsp:getProperty name="entry" property="password"/></p>
<%--The two lines are not obligatory to use; you will need them only if you wan tto print the results on the page--%>
<%-- rest of the code%-->
