How I can add a class for Ajax.ActionLink?
#Ajax.ActionLink("Remove this photo","RemovePhoto","Admin",new{Id=Model.filename, #class="ActionClass"},new AjaxOptions{OnSuccess = "RemoveSuccess"})
but this method don't create css class for this ActionLink.
My class is added to the url:
AdminTools/RemovePhoto/ffff.JPG?class=RemovePhoto
You can use the (AjaxHelper, String, String, Object, AjaxOptions, Object) method signature for this.
public static MvcHtmlString ActionLink(
this AjaxHelper ajaxHelper,
string linkText,
string actionName,
Object routeValues,
AjaxOptions ajaxOptions,
Object htmlAttributes
)
As you can see, the final parameter is a collection of HTML attributes.

Should be use like this:
#Ajax.ActionLink("Remove this photo","RemovePhoto","Admin",new{Id=Model.filename },new AjaxOptions{OnSuccess = "RemoveSuccess"} , new {#class="Action Class"})

NodeEntity:
#NodeEntity(label = "User")
public class UserNode {
#GraphId
private Long _gid;
#Index(unique = true, primary = true)
#Convert(ObjectIdConverter.class)
private ObjectId id;
}
Converter:
public class ObjectIdConverter implements AttributeConverter<ObjectId, String>{
#Override
public String toGraphProperty(ObjectId value) {
return ObjectIdUtils.compressed(value);
}
#Override
public ObjectId toEntityAttribute(String value) {
return ObjectIdUtils.uncompress(value);
}
}
Repository:
public interface UserNodeRepository extends GraphRepository<UserNode> {
#Query("MATCH (user:User) WHERE user.id IN {0} RETURN user")
List<UserNode> findByIdIn(List<ObjectId> ids);
}
UserNodeRepository#findByIdIn is custom query. but the request parameter directly convert to json without using ObjectIdConverter.
Log:
o.n.o.drivers.bolt.request.BoltRequest : Request: MATCH (user:User) WHERE user.id IN {0} RETURN user with params {0=[{timestamp=1500442853, machineIdentifier=11302907, processIdentifier=11906, counter=4709865, time=1500442853000, date=1500442853000, timeSecond=1500442853}, {timestamp=1500445335, machineIdentifier=11302907, processIdentifier=11906, counter=4709946, time=1500445335000, date=1500445335000, timeSecond=1500445335}, {timestamp=1500447522, machineIdentifier=11302907, processIdentifier=11906, counter=4710014, time=1500447522000, date=1500447522000, timeSecond=1500447522}, {timestamp=1500448399, machineIdentifier=11302907, processIdentifier=11906, counter=4710092, time=1500448399000, date=1500448399000, timeSecond=1500448399}]}
Is this the SDN expectation or what concepts have I lost?
This is not possible for finders with custom #Query. There is no way for OGM to know that your parameter relates to a property with #Convert annotation (the method name is not used at all). To solve this convert to your property type manually instead and use that as a parameter:
#Query("MATCH (user:User) WHERE user.id IN {0} RETURN user")
List<UserNode> findByIdIn(List<String> ids);
However this works fine for derived finders - OGM knows the field, and the #Convert annotation with the right converter, from the method name.
Example with single parameter:
List<UserNode> findById(ObjectId id);
Unfortunately there seems to be a bug for the IN operator and a collection parameter with:
// doesn't work
List<UserNode> findByIdIn(List<ObjectId> ids);
I have created a jira issue.
I have clients passing in IDs like this: /v1/path?id=1,2,3
What I have and want
I have a resource class for Dropwizard/Jersey.
I'd like to show up the query-parameter id=1,2,3 as a List parameter in my resource's GET method
// Resource class
public List<Something> getFilteredList(#QueryParam("id") List<String> ids) {
// filter the List<Something> based on a list of ids
}
Right now, the ids list contains 1 string which is "1,2,3".
What I tried
I tried a filter but the query parameters given by Jersey's
ContainerRequestContext.getUriInfo().getQueryParameters()
is immutable.
Questions
I would like to apply a filter and change any comma separated query parameters into multi-valued parameters so that the resource method gets a list instead.
Is there a way to change the existing query parameters using a Jersey filter?
What's a good way to solve this problem?
The best way I can think of is to just create a wrapper class for the list. This makes it easier to take advantage of the specified functionality of Jersey. You can see what I mean at Passing custom type query parameter.
For example
public class IdFilter {
private List<String> ids = new ArrayList<>();
public List<String> getIds() { return ids; }
public static IdFilter valueOf(String param) {
IdFilter filter = new IdFilter();
for (String id: param.split(",") {
filter.getIds().add(id);
}
}
}
getFilteredList(#QueryParam("id") IdFilter ids) {
We don't need to do anything else. Just having the static valueOf is enough for Jersey to know how to parse the query string.
3 ways to solve it:
use the generic context-parameter UriInfo , which is not very expressive
add an explicit custom type that can parse a comma-separated list
stay with #QueryParam List<String> requiring a concatenated query like ?id=1&id=2&id=3 given as URI
I would prefer the second as most-expressive, like answered already by Paul. This way you can concisely pass a single CSV like ?id=1,2,3,3 and also use a Set to ensure unique ID values, e.g. resulting in only [1, 2, 3].
Generic context-param UriInfo
One way would be to use a generic parameter #Context UriInfo to get the list in the method's body:
public List<Something> getFilteredList( #Context UriInfo uriInfo ) {
List<String> idList = uriInfo.getQueryParameters().get("id"); // before was #QueryParam("id")
System.out.println("idList: " + idList);
// filter a given list by ids
var somethingFiltered = getSomethingList().stream()
.filter(s -> idList.contains(s.getId()))
.collect(toList());
return Response.status(Status.OK).entity(somethingFiltered).build();
}
See the tutorial in Java Vogue(2015): QueryParam Annotation In Jersey -
Custom type with static valueOf(String) factory-method
The other way is to design a custom type which can be constructed using a String:
class IdSet {
Set<String> values;
// a factory method, can also be named valueOf
public static IdSet fromString(String commaSeparated) {
return new HashSet( Arrays.asList( commaSeparated.split(",") ) );
}
}
public List<Something> getFilteredList(#QueryParam("id") IdSet ids) {
System.out.println("ids (Set): " + ids.values);
// filter a given list by ids
var somethingFiltered = getSomethingList().stream()
.filter(s -> ids.values.contains(s.getId()))
.collect(toList());
return Response.status(Status.OK).entity(somethingFiltered).build();
}
See Jersey's JavaDocs for #QueryParam:
The type T of the annotated parameter, field or property must either:
Be a primitive type
Have a constructor that accepts a single String argument
Have a static method named valueOf or fromString that accepts a single String argument (see, for example, Integer.valueOf(String))
Have a registered implementation of ParamConverterProvider that returns a ParamConverter instance capable of a "from string" conversion for the type.
Be List<T>, Set<T> or SortedSet<T>, where T satisfies 2, 3 or 4 above. The resulting collection is read-only.
Use a collection interface with multiple key-value pairs
When the calling client uses following URI pattern: /something?id=1&id=2&id=3 then JAX-RS can deserialize them to a single parameter of List<String> id having given multiple elements:
public List<Something> getFilteredList(#QueryParam("id") List<String> ids) {
System.out.println("ids : "+ids);
// filter a given list by ids
var somethingFiltered = getSomethingList().stream()
.filter(s -> ids.contains(s.getId()))
.collect(toList());
return Response.status(Status.OK).entity(somethingFiltered).build();
}
See Mkyong: JAX-RS #QueryParam example where explained the multiple occurrences of orderBy in the GET query:
#QueryParam will convert the query parameter “orderBy=age&orderBy=name” into java.util.List automatically.

I have a controller method as follows
#RequestMapping(value = "/{fruitName:Mango|Orange|Grapes}", method = RequestMethod.GET)
public String viewFruit(ModelMap model, #PathVariable String fruitName) {
...
}
Here I am hard-coding Mango, Orange and Grapes, such that if url matches with any of these, then only this method should execute.
What I want to do is that, instead of hard-coding these fruits here. I want to declare them in a properties file and by using SPEL, I should bring it here.
Is this possible to do?
I tried code below for this, but failed with error:
#RequestMapping(value = "/{fruitName:#{fruit['seasonFruit.requestMapping']}}", method = RequestMethod.GET)
public String viewFruit(ModelMap model, #PathVariable String fruitName) {
...
}
For following properties File (fruit.properties)
seasonFruit.requestMapping = Mango|Orange|Grapes
Please suggest, how this could be achieved?
#ArtemBilan So, isn't there any way by which we could achieve this? By separation of hard coding
Well, I hope you can do that from code:
#Value("#{ environment['seasonFruit.requestMapping'] }")
private String fruitName;
#RequestMapping(value = "/{fruitName:[a-z]", method = RequestMethod.GET)
public String viewFruit(ModelMap model, #PathVariable String fruitName) {
if (fruitName.matches(this.fruitName))
}
You may not be able to use combination of REGEX and values loaded from property files in requestMapping directly. But i am able to achieve in a sample app. Essentially i am resolving the entire regex pattern from property file, not just values of it. RequestMapping can resolve values from properties file.Hope this helps.
Property file
sample.test={url:mango|orange}
Controller method:
#RequestMapping(value = { "/example/${sample.test}" }, method = RequestMethod.GET)
public String testPattern(#PathVariable String url) {
System.out.println("url:" + url);
return sample;
}
I am writing a service wherein I take in either an id or a location and I want to enforce the constraint that either the id or the location must be specified in my #Controller
#Controller
public class HelloController {
#RequestMapping(value="/loc.json",method = RequestMethod.GET)
public #ResponseBody String localiaztionRequest(#RequestParam(value = "location", required = false) String callback
,#RequestParam(value = "id", required = false) String uuid
,#RequestParam(value = "callback", required = false) String callback) {
//model.addAttribute("message", "Hello world!");
return "hello";
}
For clarity, I want each request to send either the location parameter or the id parameter. How do I enforce such a constraint on a pair of input parameters? Also as an aside could someone please explain to me the use of ModelMap , what is the effect of model.addAttribute("message","Hello World!") ?
Sorry if the questions seem rather naive, I'm extremely new to the spring framework.
Thanks in advance.
I think you should split it into two different controller methods
#RequestMapping(value="/loc.json",method = RequestMethod.GET, params={"location"})
public #ResponseBody String localizationRequestByLoc(#RequestParam String location, #RequestParam String callback) {
//model.addAttribute("message", "Hello world!");
return "hello";
}
#RequestMapping(value="/loc.json",method = RequestMethod.GET, params={"id"})
public #ResponseBody String localizationRequestById(#RequestParam String id, #RequestParam String callback) {
//model.addAttribute("message", "Hello world!");
return "hello";
}
One way to accomplish this (although indirect) would be to create a new object model representing the data to be passed in and another representing the data type and requiring both elements.
public enum MethodType
{
First,
Second
}
public class Filter
{
[Required]
public MethodType {get;set;}
[Required]
public string Data {get;set;}
}
use this object for the action method and view
and let the action method in the controller convert the object
I'm trying to test a domain class called EnityContact. Inside that class there is a method called initialize which populates some fields when needed. in order to do that the method creates instances of some other domain classes: AisUser, Entity and CPerson. AisUser is the domain class returned by the call to SecurityUtil.retrieveCurrentAisUser(false).
class EntityContact extends BaseObject implements Initializable{
....
#Override
void initialize() {
println "initaliazing"
isMain = false
creationDate = new Date()
createdBy = CPerson.get(SecurityUtil.retrieveCurrentAisUser(false).id)
entity = new Entity()
entity.setId(Long.valueOf(0)) //Id has to be initialized with some value
}
}
What i am trying to do is find a way to return mocks of those classes that i define in my specification.
Any ideas?
In Groovy you can mock static methods using MetaClass.
SecurityUtil.metaClass.'static'.retrieveCurrentAisUser = { boolean param ->
}
