Spring MVC Multiple ModelAttribute On the Same Form

Question

I have a form with two ModelAttributes one is citizens and the other is punishment. The two objects are separated by jquery tabs. I am having problems in getting the items o

Answer 1

I don't think so if you can bind multiple models using the Spring form. In fact you should take a look in the spring binding form. http://static.springsource.org/spring/docs/1.1.5/taglib/tag/BindTag.html Take a look in the sample code. I have not tested the code. Let know in case of any issues.

Model

public class User{

private String username;
private String password;

..Setter and Getters
}

public class UserProfile{
private String firstName;
private String lastName;

setter and getter
}

Controller

@Controller
public class MyController{
    @RequestMapping(....)
    public String newAccountForm(ModelMap map){
        User user = new User(); //Would recommend using spring container to create objects
        UserProfile profile = new UserProfile();

        map.addAttribute('user', user);
        map.addAttribute('profile', profile);

        return "form"
    }




     @RequestMapping(....)
        public String newAccountForm(@ModelAttrbite('User')User user, BindingResult resultUser, @ModelAttribute('UserProfile')UserProfile userProfile, BindingResult resultProfile){

//Check the binding result for each model. If not valid return the form page again
//Further processing as required.

        }
    }

JSP

<%@taglib  uri="http://www.springframework.org/tags" prefix="spring">

<form action="" method="post">

<spring:bind path="user.username">
   <input type="text" name="${status.expression}" value="${status.value}"><br />
        </spring:bind>

<spring:bind path="user.password">
   <input type="password" name="${status.expression}" value="${status.value}"><br />
        </spring:bind>

<spring:bind path="profile.firstName">
   <input type="text" name="${status.expression}" value="${status.value}"><br />
        </spring:bind>
<spring:bind path="profile.lastName">
   <input type="text" name="${status.expression}" value="${status.value}"><br />
        </spring:bind>

<input type="submit" value="Create"/>
</form>

I already gave alternate approach in this link here

<form:form method="POST" modelAttribute="applicationGeneralInformation">
  <div class="section2">
    <h2>General Informaion</h2>

    <form:input type="hidden" path="id" id="id"/>
    <label for="app_version">Version</label>: <form:input type="text" id="app_version" path="version"/><br/>
    <label for="app_func_desc">Description</label>: <form:input type="text" id="app_func_desc"
                                                                       path="functionalDescription"/><br/>
   <label for="app_sec_func">Functions</label>: <form:input type="text" id="app_sec_func"
                                                                  path="securityFunctions"/><br/>

</div>
<div class="section2">
  <h2>Application Content</h2>
  <form:form method="POST" modelAttribute="applicationContent">
    <div>
        <h3>CIA Rating</h3>
        <label for="CIARating">CIA Rating</label>: <form:select type="text" id="CIARating" path="CIARating">
        <form:option value="1">1</form:option>
        <form:option value="2">2</form:option>
        <form:option value="3">3</form:option>
        <form:option value="4">4</form:option>
    </form:select><br/><br/>
    </div>
    <div>
        <h3>Business Continuity and Disaster Recovery</h3>
        <div>
            <h4>RTO</h4>
            <label for="RTO">RTO</label>: <form:select type="text" id="RTO" path="RTO">
            <form:option value="1">< 2<sub>Hrs</sub></form:option>
            <form:option value="2">2<sub>Hrs</sub>-4<sub>Hrs</sub>    </form:option>
            <form:option value="3">4<sub>Hrs</sub>-48<sub>Hrs</sub></form:option>
            <form:option value="4">> 48<sub>Hrs</sub></form:option>
        </form:select><br/>
        </div>
        <div>
            <h4>RPO</h4>
            <label for="RPO">RPO</label>: <form:input type="text" id="RPO" path="RPO"/><br/>
        </div>
    </div>
  </form:form>
  <input type="submit" value="Submit">
 </div>
 </form:form>
