i was wondering about the spring scope equivalent to window scope ?
according to the documentation here
http://static.springsource.org/spring/docs/3.0.0.M3/spring-framework-reference/html/ch04s04.html
i couldn't find any, so if there's a custom scope equivalent, can anyone please tell me, thanks.
EDIT: example of window scope in JSF
http://icefaces-showcase.icesoft.org/showcase.jsf?grp=compatMenu&exp=popup
One possible approach is having a session scoped bean that holds all the window sessions, and a window custom scope that access to the corresponding bean through that session scoped bean.
The required classes are:
Window Session
public class WindowSession {
private Map<String, Map<String,Object>> scopeMap = new HashMap<String, Map<String,Object>>();
private Map<String, Boolean> validSessions = new HashMap<String, Boolean>();
public WindowSession() {
super();
}
public Map<String, Map<String, Object>> getScopeMap() {
return scopeMap;
}
public void setScopeMap(Map<String, Map<String, Object>> scopeMap) {
this.scopeMap = scopeMap;
}
public Map<String, Boolean> getValidSessions() {
return validSessions;
}
public void setValidSessions(Map<String, Boolean> validSessions) {
this.validSessions = validSessions;
}
}
WindowIdContext
#Service
#Scope(value="request", proxyMode=ScopedProxyMode.TARGET_CLASS)
public class WindowIdContext {
public static final String DEFAULT_SESSION_ID = "";
private String id = DEFAULT_SESSION_ID;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getQueryParamWithSessionId() {
if (DEFAULT_SESSION_ID.equals(id)) {
return "";
}
return "?" + WindowScope.WINDOW_ID_PARAM + "=" + id;
}
}
WindowSessionContext
#Service
#Scope(value="session", proxyMode=ScopedProxyMode.TARGET_CLASS)
public class WindowSessionContext {
private static SecureRandom random = new SecureRandom();
private WindowSession windowSession = new WindowSession();
#Autowired
private WindowIdContext windowIdContext;
public WindowSessionContext() {
windowSession.getValidSessions().put(WindowIdContext.DEFAULT_SESSION_ID, false);
}
public Object getObject(String name, ObjectFactory<?> objectFactory) {
String sessionId = windowIdContext.getId();
synchronized(this) {
if (!windowSession.getValidSessions().containsKey(sessionId)) {
windowSession.getValidSessions().put(sessionId, false);
}
Map<String,Object> sessionMap = windowSession.getScopeMap().get(sessionId);
if (sessionMap == null) {
sessionMap = new HashMap<String,Object>();
windowSession.getScopeMap().put(sessionId, sessionMap);
}
Object object = sessionMap.get(name);
if (object == null) {
object = objectFactory.getObject();
sessionMap.put(name, object);
}
return object;
}
}
public Object removeObject(String name) {
String sessionId = windowIdContext.getId();
synchronized(this) {
Map<String,Object> sessionMap = windowSession.getScopeMap().get(sessionId);
if (sessionMap == null) {
return null;
}
Object object = sessionMap.remove(name);
return object;
}
}
public String addSession() {
synchronized(this) {
String sessionId;
do {
sessionId = new BigInteger(130, random).toString(32);
} while (windowSession.getValidSessions().containsKey(sessionId));
windowSession.getValidSessions().put(sessionId, false);
return sessionId;
}
}
public void removeSession() {
String sessionId = windowIdContext.getId();
synchronized(this) {
windowSession.getScopeMap().remove(sessionId);
windowSession.getValidSessions().remove(sessionId);
}
}
public boolean isSessionValid(String sessionId) {
Boolean inUse = windowSession.getValidSessions().get(sessionId);
return inUse != null;
}
public boolean isSessionInUse(String sessionId) {
Boolean inUse = windowSession.getValidSessions().get(sessionId);
return inUse == true;
}
public synchronized boolean invalidateSession(String sessionId) {
Boolean valid = windowSession.getValidSessions().get(sessionId);
if (valid == null) {
return false;
}
if (sessionId.equals(WindowIdContext.DEFAULT_SESSION_ID)) {
windowSession.getValidSessions().put(sessionId, false);
} else {
windowSession.getValidSessions().remove(sessionId);
}
windowSession.getScopeMap().remove(sessionId);
for (Entry<String,Boolean> validSession : windowSession.getValidSessions().entrySet()) {
if (validSession.getValue() == true) {
return false;
}
}
return true;
}
public synchronized void setSessionInUse(String sessionId) {
windowSession.getValidSessions().put(sessionId, true);
}
public int getCount() {
return windowSession.getValidSessions().size();
}
}
WindowScope
public class WindowScope implements Scope {
private final int scope;
private static final int WINDOW_SCOPE = 40;
public static final String NAME = "window";
public static final String WINDOW_ID_PARAM = "windowid";
private ServletContext servletContext = null;

I'm trying to implement this solution but ViewResolver is not injected and it's null. I'm using Spring boot 2.x
get contents of processed JSP into spring controller without using HttpClient?
I already researched online and read documentation.
How do I properly inject the ViewResolver so the solution works?
#Service

if (viewResolver.resolveViewName(viewName, localeResolver.resolveLocale(request)) != null) {
return true;
}
} catch (Exception e) {

return false;

Currently, I have AuthFilter and here I received an UserState. I need to pass it to the next Filter. But how to do it right? Or exists other practices to resolve it?
public class AuthFilter extends ZuulFilter {
#Autowired
private AuthService authService;
#Autowired
private ApplicationContext appContext;
#Override
public String filterType() {
return PRE_TYPE;
}
#Override
public int filterOrder() {
return PRE_DECORATION_FILTER_ORDER - 2;
}
#Override
public boolean shouldFilter() {
RequestContext context = RequestContext.getCurrentContext();
String requestURI = context.getRequest().getRequestURI();
for (String authPath : authPaths) {
if (requestURI.contains(authPath)) return true;
}
return false;
}
#Override
public Object run() throws ZuulException {
try {
UserState userState = authService.getUserData();
DefaultListableBeanFactory context = new DefaultListableBeanFactory();
GenericBeanDefinition beanDefinition = new GenericBeanDefinition();
beanDefinition.setBeanClass(UserState.class);
beanDefinition.setPropertyValues(new MutablePropertyValues() {
{
add("user", userState);
}
});
context.registerBeanDefinition("userState", beanDefinition);
} catch (UndeclaredThrowableException e) {
if (e.getUndeclaredThrowable().getClass() == UnauthorizedException.class) {
throw new UnauthorizedException(e.getMessage());
}
if (e.getUndeclaredThrowable().getClass() == ForbiddenException.class) {
throw new ForbiddenException(e.getMessage(), "The user is not allowed to make this request");
}
}
return null;
}
}
I pretty sure filters are chained together and the request/response are passed through them. You can add the data to the request, and have the next filter look for it.
I have following methods.
public ResponseEntity some(#PathVariable("id") final String id_) {
final Long id = ((Supplier<Long>) () -> {
try {
if (id_ == null || id_.equals("dontcare")) {
return null;
}
return Long.parseLong(id_);
} catch (final NumberFormatException nfe) {
throw new RuntimeException(nfe);
}
}).get();
}
As you can assume I want my parameter value \d+ or dontcare.
How or What can I use for do following?
public ResponseEntity some(
#Dontcare #PathVariable("id") final Long id) {
}
I found WebArgumentHandler, HandlerMethodArgumentResolver, and PathVariableMethodArgumentResolver, but I can't find any good example.
Please help me.
UPDATE
I prepared following class.
public class DontcarePathVariableResolver
extends PathVariableMethodArgumentResolver {
#Override
public boolean supportsParameter(MethodParameter parameter) {
final boolean flag = parameter.getMethodAnnotation(
DontcarePathVariable.class) != null;
logger.info("flag: {}", flag);
return flag;
}
#Override
protected Object resolveName(String name, MethodParameter parameter,
NativeWebRequest request)
throws Exception {
#SuppressWarnings({"unchecked"})
final Map<String, String> templateVariables
= (Map<String, String>) request.getAttribute(
HandlerMapping.URI_TEMPLATE_VARIABLES_ATTRIBUTE,
RequestAttributes.SCOPE_REQUEST);
final String pathValue = templateVariables.get(name);
return new DontcareConverter().convert(pathValue);
}
}
And added it.
#Configuration
public class WebMvcConfiguration extends WebMvcConfigurerAdapter {
#Override
public void addArgumentResolvers(final List<HandlerMethodArgumentResolver> resolvers) {
resolvers.add(new DontcarePathVariableMethodArgumentResolver());
logger.info("resolver added");
//super.addArgumentResolvers(resolvers);
}
}
But it did come to play.
I think a default handler for Long type is already in play.
I have searched and can't find any examples that would show me a better way to do this, but in the Spring/Spring Boot code, there are generic builders but the builder itself seems to apply the properties programmatically. Here is some code trying to configure 2 Oracle Connection Pool Data Sources:

Preferably, I would like to be able to apply the properties directly to the builder in one place. is this possible? what changes would I have to make?
Thanks...
Here is your builder, sir
public class OracleUcpDataSourceBuilder {
private Map<String, String> properties = new HashMap<String, String>();
private static final String[] REQ_PROPERTIES = new String[] {"username", "password", "URL"};
public static OracleUcpDataSourceBuilder create() {
return new OracleUcpDataSourceBuilder();
}
public DataSource build() {
for (String prop : REQ_PROPERTIES) {
Assert.notNull(properties.get(prop), "Property is required:" + prop);
}
PoolDataSource result = PoolDataSourceFactory.getPoolDataSource();
bind(result);
return result;
}
private void bind(DataSource result) {
MutablePropertyValues properties = new MutablePropertyValues(this.properties);
new RelaxedDataBinder(result).bind(properties);
}
public OracleUcpDataSourceBuilder URL(String url) {
this.properties.put("URL", url);
return this;
}
public OracleUcpDataSourceBuilder username(String username) {
this.properties.put("username", username);
return this;
}
public OracleUcpDataSourceBuilder password(String password) {
this.properties.put("password", password);
return this;
}
}
Just define a bean like this:
#Bean (name = "readOnlyDataSource")
#ConfigurationProperties(prefix = "datasource.readonly")
public DataSource getReadOnlyDataSource() {
return OracleUcpDataSourceBuilder.create().build();
}
Just make sure that the property names are correct. Spring will take care of the rest.
Note: I use DataSourceBuilder or Spring as a reference.. You can check it's source code also.
Edit: Added some methods to make sure some properties are configured. But this way, you need to set those properties manually to make sure that they're available.
Well, I have an abstract class like this:
public abstract class BasicCrudMBImpl<Bean, BO> extends BasicMBImpl {
protected Bean bean;
protected List<Bean> beans;
protected BO boPadrao;
public void deletar() {
try {
((BasicBO) boPadrao).delete((AbstractBean) bean);
addInfoMessage("Registro deletado com sucesso");
beans = retornaBeansDoBanco();
bean = null;
} catch (BOException e) {
addErrorMessage(e.getMessage());
}
}
public void salvar(ActionEvent event) {
try {
if (((AbstractBean) bean).getId() == null) {
bean = (Bean) ((BasicBO) boPadrao).save((AbstractBean) bean);
addInfoMessage("Registro salvo com sucesso");
} else {
((BasicBO) boPadrao).update((AbstractBean) bean);
addInfoMessage("Registro atualizado com sucesso");
}
beans = retornaBeansDoBanco();
} catch (BOException e) {
FacesContext.getCurrentInstance().validationFailed();
addErrorMessage(e.getMessage());
}
}
public Bean getBean() {
return bean;
}
public void setBean(Bean bean) {
this.bean = bean;
}
public List<Bean> getBeans() {
try {
if (beans == null)
beans = (List<Bean>) retornaBeansDoBanco();
return beans;
} catch (BOException e) {
addErrorMessage(e.getMessage());
}
return null;
}
public void setBeans(List<Bean> beans) {
this.beans = beans;
}
// Deve ser implementado para carregar a query adequada ao bean necessário
public abstract List<Bean> retornaBeansDoBanco();
public abstract void novo(ActionEvent event);
public abstract void alterar(ActionEvent event);
public BO getBoPadrao() {
return boPadrao;
}
public abstract void setBoPadrao(BO boPadrao);
public void addErrorMessage(String componentId, String errorMessage) {
addMessage(componentId, errorMessage, FacesMessage.SEVERITY_ERROR);
}
public void addErrorMessage(String errorMessage) {
addErrorMessage(null, errorMessage);
}
public void addInfoMessage(String componentId, String infoMessage) {
addMessage(componentId, infoMessage, FacesMessage.SEVERITY_INFO);
}
public void addInfoMessage(String infoMessage) {
addInfoMessage(null, infoMessage);
}
private void addMessage(String componentId, String errorMessage,
FacesMessage.Severity severity) {
FacesMessage message = new FacesMessage(errorMessage);
message.setSeverity(severity);
FacesContext.getCurrentInstance().addMessage(componentId, message);
}
}
In ManagedBean I tried to inject the "boPadrao" with #Autowired, like this:
#ManagedBean(name = "enderecoMB")
#ViewScoped
public class EnderecoMBImpl extends BasicCrudMBImpl<Endereco, BasicBO> {
private static Logger logger = Logger.getLogger(EnderecoMBImpl.class);
private List<TipoEndereco> tiposEndereco;
private List<Logradouro> logradouros;
#PostConstruct
public void init() {
logger.debug("Inicializando componentes no PostConstruct");
beans = retornaBeansDoBanco();
tiposEndereco = (List<TipoEndereco>) boPadrao
.findByNamedQuery(TipoEndereco.FIND_ALL);
logradouros = (List<Logradouro>) boPadrao
.findByNamedQuery(Logradouro.FIND_ALL_COMPLETO);
}
#Override
public List<Endereco> retornaBeansDoBanco() {
return (List<Endereco>) getBoPadrao().findByNamedQuery(Endereco.FIND_ALL_COMPLETO);
}
#Override
public void novo(ActionEvent event) {
bean = new Endereco();
}
#Override
public void alterar(ActionEvent event) {
// TODO Auto-generated method stub
}
public List<TipoEndereco> getTiposEndereco() {
return tiposEndereco;
}
public void setTiposEndereco(List<TipoEndereco> tiposEndereco) {
this.tiposEndereco = tiposEndereco;
}
public List<Logradouro> getLogradouros() {
return logradouros;
}
public void setLogradouros(List<Logradouro> logradouros) {
this.logradouros = logradouros;
}
#Autowired
public void setBoPadrao(BasicBO boPadrao) {
this.boPadrao = boPadrao;
}
}
But this doesn't works, the boPadrao is always null, getting a "NullPointerException". The error occurs in method retornaBeansDoBanco();
