Method Detail

initBinder

protected void initBinder(javax.servlet.http.HttpServletRequest request,
                          org.springframework.web.bind.ServletRequestDataBinder binder)
                   throws Exception

Description copied from class: org.springframework.web.servlet.mvc.BaseCommandController

Initialize the given binder instance, for example with custom editors. Called by BaseCommandController.createBinder(javax.servlet.http.HttpServletRequest, java.lang.Object).

This method allows you to register custom editors for certain fields of your command class. For instance, you will be able to transform Date objects into a String pattern and back, in order to allow your JavaBeans to have Date properties and still be able to set and display them in an HTML interface.

The default implementation is empty.

Overrides:

initBinder in class org.springframework.web.servlet.mvc.BaseCommandController

Parameters:

request - current HTTP request

binder - the new binder instance

Throws:

Exception - in case of invalid state or arguments

See Also:

BaseCommandController.createBinder(javax.servlet.http.HttpServletRequest, java.lang.Object), DataBinder.registerCustomEditor(java.lang.Class<?>, java.beans.PropertyEditor), CustomDateEditor

onSubmit

protected org.springframework.web.servlet.ModelAndView onSubmit(javax.servlet.http.HttpServletRequest request,
                                                                javax.servlet.http.HttpServletResponse response,
                                                                Object obj,
                                                                org.springframework.validation.BindException errors)
                                                         throws Exception

The onSubmit function receives the form/command object that was modified by the input form and saves it to the db

Overrides:

onSubmit in class org.springframework.web.servlet.mvc.SimpleFormController

Parameters:

request - current servlet request

response - current servlet response

obj - form object with request parameters bound onto it

errors - Errors instance without errors (subclass can add errors if it wants to)

Returns:

the prepared model and view, or null

Throws:

Exception - in case of errors

See Also:

SimpleFormController.onSubmit(javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse, java.lang.Object, org.springframework.validation.BindException)

formBackingObject

protected Object formBackingObject(javax.servlet.http.HttpServletRequest request)
                            throws javax.servlet.ServletException

This is called prior to displaying a form for the first time. It tells Spring the form/command object to load into the request

Overrides:

formBackingObject in class org.springframework.web.servlet.mvc.AbstractFormController

Parameters:

request - current HTTP request

Returns:

the backing object

Throws:

javax.servlet.ServletException

See Also:

AbstractFormController.formBackingObject(javax.servlet.http.HttpServletRequest)

referenceData

protected Map<String,Object> referenceData(javax.servlet.http.HttpServletRequest request,
                                           Object obj,
                                           org.springframework.validation.Errors errors)
                                    throws Exception

Description copied from class: org.springframework.web.servlet.mvc.SimpleFormController

Create a reference data map for the given request and command, consisting of bean name/bean instance pairs as expected by ModelAndView.

The default implementation delegates to SimpleFormController.referenceData(HttpServletRequest). Subclasses can override this to set reference data used in the view.

Overrides:

referenceData in class org.springframework.web.servlet.mvc.SimpleFormController

Parameters:

request - current HTTP request

obj - form object with request parameters bound onto it

errors - validation errors holder

Returns:

a Map with reference data entries, or null if none

Throws:

Exception - in case of invalid state or arguments
