How get Date object after convert

[a_subscriber]

my config. bean:

	<bean id="dateEditor"
		class="org.springframework.beans.propertyeditors.CustomDateEditor">
		<constructor-arg>
			<bean class="java.text.SimpleDateFormat">
				<constructor-arg value="dd.MM.yyyy" />
			</bean>
		</constructor-arg>
		<constructor-arg value="true" />
	</bean>

	<bean class="org.springframework.beans.factory.config.CustomEditorConfigurer">
		<property name="customEditors">
			<map>
				<entry key="java.util.Date">
					<ref local="dateEditor" />
				</entry>
			</map>
		</property>
	</bean>


	<bean id="usersController" class="com.mycompany.myproject.web.controllers.UsersController">
		<property name="dateEditor" ref="dateEditor" />
	</bean>

my controller:

public class UsersController extends MultiActionController {
	private CustomDateEditor dateEditor;

public void setDateEditor(CustomDateEditor dateEditor) {
		this.dateEditor = dateEditor;
	}

@Override
	protected void bind(HttpServletRequest request, Object command)
			throws Exception {
		ServletRequestDataBinder servletRequestDataBinder = createBinder(
				request, command);
		servletRequestDataBinder.registerCustomEditor(java.util.Date.class,
				"dateFrom", dateEditor);
		servletRequestDataBinder.registerCustomEditor(java.util.Date.class,
				"dateTo", dateEditor);
		servletRequestDataBinder.bind(request);
		bindingResult = servletRequestDataBinder.getBindingResult();
	}

public ModelAndView add(HttpServletRequest request,
			HttpServletResponse response, UserView userView) throws Exception {
 // Here I need Date objects from fields "dateFrom" and "dateTo"
...

No errors, but how I can get Date objects in my method "add" ?

CustomEditorConfigurer is only used for reading/parsing the application context NOT for your controllers. Next to that NEVER inject a PropertyEditor, PropertyEditors are by design not thread safe, create a new one in your controller.

How get date object after parse?

[Marten Deinum]

They are part of your form object (assumingbly UserView). Simply get them...

When then the date not insert to DB?
my controller:

public class UsersController extends MultiActionController {
@Override
	protected void bind(HttpServletRequest request, Object command)
			throws Exception {
		UserView userView = (UserView) command;
		ServletRequestDataBinder servletRequestDataBinder = createBinder(
				request, userView);
		servletRequestDataBinder.registerCustomEditor(Date.class,
				new CustomDateEditor(new SimpleDateFormat("dd.MM.yyyy"),
						true));
		servletRequestDataBinder.bind(request);
		bindingResult = servletRequestDataBinder.getBindingResult();
		logger.info("dateFrom="+userView.getDateFrom());
	}

my dao obejct:

public class JdbcUserDao extends SimpleJdbcDaoSupport implements UserDao {
private static final String USER_INSERT = "INSERT INTO users "

			+ "VALUES (:firstName,:lastName,:pin,:email,:mobile,:branch,:login,:password,:cpnl,"
			+ ":disabledPermanently,:dateFrom,:dateTo,:plc,:nil)";
@Override
	public void add(User user) {
		SqlParameterSource parameterSource = new BeanPropertySqlParameterSource(
				user);
		Branch branch = (Branch) parameterSource.getValue("branch");
		Map<String, Object> parameters = new HashMap<String, Object>();
		parameters.put("id", user.getId());
		parameters.put("firstName", user.getFirstName());
		parameters.put("lastName", user.getLastName());
		parameters.put("pin", user.getPin());
		parameters.put("email", user.getEmail());
		parameters.put("mobile", user.getMobile());

		parameters.put("dateTo", user.getDateTo());
		parameters.put("plc", user.getPlc());
		parameters.put("nil", user.getNil());
		parameterSource = new MapSqlParameterSource(parameters);
                     logger.info("dateFrom=" + user.getDateFrom());
		logger.info("dateTo=" + user.getDateTo())
		getSimpleJdbcTemplate().update(USER_INSERT, parameterSource);

I would think something is wrong with your binding (as I stated earlier you might want to read a book instead of asking 4 questions a day...). Check your types (are both types class and used to configure binding the same Date class (java.util or javax.sql) ). Are your fields properly bound from/to the jsp.

CustomEditorConfigurer is only used for reading/parsing the application context NOT for your controllers. Next to that NEVER inject a PropertyEditor, PropertyEditors are by design not thread safe, create a new one in your controller.

Where I get more information about thread safe?

This solution is a thread safe?
bean:

	<bean id="dateFormat" class="java.text.SimpleDateFormat">
		<constructor-arg value="dd.MM.yyyy" />
	</bean>

	<bean id="usersController" class="com.mycompany.myproject.web.controllers.UsersController">
		<property name="dateFormat" ref="dateFormat" />
	</bean>

my controller:

public class UsersController extends MultiActionController {
	private DateFormat dateFormat;
public void setDateFormat(DateFormat dateFormat) {
		this.dateFormat = dateFormat;
	}

@Override
	protected void bind(HttpServletRequest request, Object command)
			throws Exception {
		UserView userView = (UserView) command;
		ServletRequestDataBinder servletRequestDataBinder = createBinder(
				request, userView);
		servletRequestDataBinder.registerCustomEditor(Date.class,
				new CustomDateEditor(dateFormat, true));
		servletRequestDataBinder.bind(request);
		bindingResult = servletRequestDataBinder.getBindingResult();
	}

No. Formatters aren't threadsafe either, so you really need to construct those objects inside your controller.

Information regarding thread safety, i suggest the JavaBeans specification or just learn the implementation. Classes which keep state are basically not thread safe.

OK here the threadsafe solution:

@Override
	protected void bind(HttpServletRequest request, Object command)
			throws Exception {
		UserView userView = (UserView) command;
		ServletRequestDataBinder servletRequestDataBinder = createBinder(
				request, userView);
		servletRequestDataBinder.registerCustomEditor(Date.class,
				new CustomDateEditor(new SimpleDateFormat("dd.MM.yyyy"),
						true));
		servletRequestDataBinder.bind(request);
		bindingResult = servletRequestDataBinder.getBindingResult();
	}

And if I have 50 controllers I need to every controller write servletRequestDataBinder.registerCustomEditor(Date .class,
new CustomDateEditor(new SimpleDateFormat("dd.MM.yyyy")..
But suppose that tomorrow I need to change date pattern from dd.MM.yyyy to MM-dd-yyyy. And I need to change and recompile 50 controllers!!! I think it's not good. The ideal solution is to make change ONLY IN ONE PLACE without recompile my code

Sigh... As I suggested about 5 times, read a book, read the reference guide... Instead you are complaining, asking x questions a day, sometimes the same questions which doesn't really help you getting more help from the community.

Again I suggest the reference guide, scroll down to section 5.4.2.1.1.

Also instead of using the old, hard to get working MultiActionController I suggest a annotation based controller which is easier to use/configure.
