Spring exception - NotReadablePropertyException: Invalid property - spring

Question

I'm trying to create a form to add an object into the database.
The model for the form
public class Module implements Serializable{
private static final long serialVersionUID = 8825646974241476909L;
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Column(name = "module_id")
private Long moduleId;
#Column(name = "module_code")
private String moduleCode;
#Column(name = "module_name")
private String moduleName;
//getters and setters
public Long getModuleId() {
return moduleId;
}
public void setModuleId(Long moduleId) {
this.moduleId = moduleId;
}
public String getModuleCode() {
return moduleCode;
}
public void setModuleCode(String moduleCode) {
this.moduleCode = moduleCode;
}
public String getModuleName() {
return moduleName;
}
public void setModuleName(String moduleName) {
this.moduleName = moduleName;
}
The form
<c:url var="saveUrl" value="/admin/addModule" />
<form:form modelAttribute="module" method="POST" action="${saveUrl}" name="module">
<table>
<tr>
<td><form:hidden path="moduleId"/></td>
</tr>
<tr>
<td><form:label path="moduleCode">Module Code:</form:label></td>
<td><form:input path="moduleCode"/></td>
</tr>
</table>
<input type="submit" name="submit" value="Save" />
</form:form>
Controller
#RequestMapping(value = "/admin/addModule", method = RequestMethod.GET)
public String getAdminAddModule(#ModelAttribute("module") ModelMap map) {
map.addAttribute("module", new Module());
// This will resolve to /WEB-INF/jsp/addedpage.jsp
return "/admin/addModule";
}
When I try to access the form an error keeps coming up on all of the properties. This is the stacktrace error for the moduleId property.

I have all of the setter and getters but the error is persistent.

Answer 1

You should remove the #ModelAttribute against ModelMap parameter. That parameter is automatically populated by Spring and gives you a way of populating the model objects, which you are later doing with map.addAttribute("module", new Module());.
Removing #ModelAttribute should fix it for you.
