Trying to apply MVC Spring Validation to my web project. I think I have everything configured properly, but my form is not being validated.
I am not using Maven or Gradle. Rather, I am including the jar files I was told I needed by my tutorial in my build path.
The jar files are: validation-api-1.1.0.Final.jar hibernate-validator-5.0.1.Final.jar
I am following this tutorial: https://www.codejava.net/frameworks/spring/spring-mvc-form-validation-example-with-bean-validation-api
My config.xml file:
<?xml version="1.0" encoding="UTF-8"?>

My Model:
package bl;
import javax.validation.constraints.Size;
import org.hibernate.validator.constraints.NotEmpty;
public class VendorValidation {
@NotEmpty
@Size(min = 1, message = "Field requires an entry")
private String vname;
@NotEmpty
private String vphone;
@NotEmpty
private String vemail;
@NotEmpty
private String vcity;
@NotEmpty
private String vstate;
@NotEmpty
private String vcountry;
@NotEmpty
private String vzipcode;
@NotEmpty
private String vtimezone;
public String getVname() {
return vname;
}
public void setVname(String vname) {
this.vname = vname;
}
public String getVphone() {
return vphone;
}
public void setVphone(String vphone) {
this.vphone = vphone;
}
public String getVemail() {
return vemail;
}
public void setVemail(String vemail) {
this.vemail = vemail;
}
public String getVcity() {
return vcity;
}
public void setVcity(String vcity) {
this.vcity = vcity;
}
public String getVstate() {
return vstate;
}
public void setVstate(String vstate) {
this.vstate = vstate;
}
public String getVcountry() {
return vcountry;
}
public void setVcountry(String vcountry) {
this.vcountry = vcountry;
}
public String getVzipcode() {
return vzipcode;
}
public void setVzipcode(String vzipcode) {
this.vzipcode = vzipcode;
}
public String getVtimezone() {
return vtimezone;
}
public void setVtimezone(String vtimezone) {
this.vtimezone = vtimezone;
}
}
My View:
<form:form method="post" id="va-form" action="insertVendor" modelAttribute="vendorValidation">
<div class="form-group">
<label>Vendor Name</label> <form:input type="text" path="vname" class="form-control"
id="nameForm" />
</div>
...
</form:form>
My Controller:
@RequestMapping(value = "vendorForm", method = RequestMethod.GET)
public String formView(ModelMap map, HttpServletRequest request) {
VendorValidation vendorValidation = new VendorValidation();
map.put("vendorValidation", vendorValidation);
return "vendorForm";
}
RequestMapping(value = "/insertVendor", method = RequestMethod.POST)
public String insertVendor(@Valid @ModelAttribute("vendorValidation") VendorValidation vendorValidation, BindingResult result,
HttpServletRequest request, ModelMap model) {
System.out.println("Found form errors: " + result.hasErrors());
if (result.hasErrors())
{
return "vendorForm";
}
else
{
// database logic
return "vendormanagement";
}
}
The BindingResult object does not contain any errors when attempting to submit the form and it should when I leave my fields empty. So the if (result.hasErrors()) does not fire and I get a database exception for trying to insert null values.
