Spring 3 form validation

[sachin pachpute]

Hi,

In my application I want to validate the field which contains reference to another domain object (Address in this case). I am able to validate name and age fields, but not able to validate fields from Address class (no message is displayed on jsp).

public class Customer {	

	String name;	
	int age;
       Address address;
 
	//getter and setter methods 
}

public class Address{	

	String postcode;	
	int houseNumber;
        String roadName;
 
	//getter and setter methods 
}

Show us what you have tried. What does your JSP.,controller, validation logic look like?

Details given below. Please note that validation is working fine for Article (only few fields I am validating for now), but isn't working for User which is referred from Article.

Article.java

@Entity
@Table(name = "article")
public class Article {

	@Id
	@GeneratedValue
	@Column(name = "ID")
	private Long articleId;

	@Column(name = "TITLE")
	@NotEmpty
	private String articleTitle;

	@Column(name = "LOCATION", nullable = false)
	@NotEmpty
	private String articleLocation;
	
	@Column(name = "DESCRIPTION")
	@NotEmpty
	private String articleDescription;
	
	@Column(name = "RENT")
	private int articleRent;
	
	@Column(name = "CATEGORY")
	private int articleCategory;
	
	@OneToOne(cascade = CascadeType.ALL)
	private User user;
	

User.java

	@Id
	@GeneratedValue
	@Column(name = "ID")
	private Long userId;

	@Column(name = "LOGIN_ID", length = 45)
	private String login;

	@Column(name = "PASSWORD", length = 45)
	private String password;

	@Column(name = "FIRST_NAME")
	@NotEmpty
	private String firstName;

	@Column(name = "LAST_NAME")
	@NotEmpty
	private String lastName;

	@Column(name = "EMAIL_ID")
	@Email
	private String emailId;

	@Column(name = "PHONE")
	@NotNull
    @Size(min = 10, max = 14)
	private String phone;

ArticleController.java

	@RequestMapping(value = "/save", method = RequestMethod.POST)
	public String saveArticle(@Valid Article article,
			BindingResult result, HttpServletRequest request, Model model) {
		
		if (result.hasErrors()) {
			return "addArticle";
		}

		try {
			MultipartFile file = article.getFileData();

relevant snippet from despatcher servlet (for JSR 303 & messages) is as below,

<mvc:annotation-driven/>

<bean id="messageSource" class="org.springframework.context.support.ResourceBundleMessageSource">
        <property name="basename" value="/WEB-INF/messages"/>
</bean>

addArticle.jsp

<li>
	<form:label path="user.firstName">Name*</form:label>
	<div>	                        
		<form:input path="user.firstName" type="text" maxlength="70" id="firstName" value=""/>
		<form:errors path="user.firstName" class="error"/>	                        
		<form:input path="user.lastName" type="text" maxlength="70" id="lastName" value="""/>
		<form:errors path="user.lastName" class="error"/>
	</div>
</li>
<li>
	<form:label path="user.emailId">Email address*</form:label>	                    
	<div>	                        
		<form:input path="user.emailId" type="text" maxlength="145" id="emailId" value=""/>
		<form:errors path="user.emailId" class="error"/>	                        
	</div>
</li>

This problem is resolved for me now. Just read the document at http://docs.jboss.org/hibernate/validator/4.0.1/reference/en/html/validator-usingvalidator.html

I added,

@NotNull
@Valid

before

@OneToOne(cascade = CascadeType.ALL)  
    private User user;
