resolver

问题 Note: The underlying situation of this question is also part of a slightly different question here. Situation I have a trunk, where earlier, a branch has been made from. Then, in the trunk some file renamings have been made. These renamings were accidentially made by "copy/delete", not with the proper svn rename process as they should have. This is described in the TSVN docs, and in my case the "Repair move" was omitted. Now I have tree conflicts, when merging the branch back to the trunk:

问题 I am trying to output some model data to a pdf using spring-mvc. It is not working and I was wondering if someone could offer some advice. I have a spring-servlet.xml file that includes the following: <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="order" value="1"/> <property name="prefix" value="/WEB-INF/view/"/> <property name="suffix" value=".jsp"/> </bean> <bean id="xmlViewResolver" class="org.springframework.web.servlet

问题 But I was trying to understand the usage of Providers in jax-rs. But was not able to understand how ContextResolver can be used. Can someone explain this with some basic example? 回答1: You will see it being used a lot in resolving a serialization context object. For example an ObjectMapper for JSON serialization. For example @Provider @Produces(MediaType.APPLICATION_JSON) public static JacksonContextResolver implements ContextResolver<ObjectMapper> { private final ObjectMapper mapper; public

问题 I'm working through the Angular2 testing guide and wish to write a test for the ngOnInit() function. The one from the Routing part of the programming guide has this format: let org: Org = null; ngOnInit(): void { let that = this; this.route.data .subscribe((data: { org: Org }) => { that.org = data.org; }); } This is fulfilled through a resolver, like: resolve(route: ActivatedRouteSnapshot, state: RouterStateSnapshot): Observable<Org> { let id = this.authService.user.orgId; return this

问题 I'm wondering what is the best way to retrieve nested properties in Groovy, taking a given Object and arbitrary "property" String. I would like to something like this: someGroovyObject.getProperty("property1.property2") I've had a hard time finding an example of others wanting to do this, so maybe I'm not understanding some basic Groovy concept. It seems like there must be some elegant way to do this. As reference, there is a feature in Wicket that is exactly what I'm looking for, called the

问题 So I implemented a resolver in angular 5: @Injectable() export class AppResolver implements Resolve<MyComplexObject []> { constructor(private myService: MyService) { } resolve(route: ActivatedRouteSnapshot, state: RouterStateSnapshot): Observable<MyComplexObject[]> { return this.myService.getMyApi(myOption); // my option is a string } } right now myOption is a hardcoded string and i want to change that in my routing module i have: resolve: { myResolver: AppResolver } I suppose maybe here I

问题 I'm trying to integrate my REST API (NestJS) with new Neo4j database with GraphQL queries. Anybody succeed? Thanks in advance EDIT 1: (I added my code) import { Resolver } from "@nestjs/graphql"; import { Query, forwardRef, Inject, Logger } from "@nestjs/common"; import { Neo4jService } from "src/shared/neo4j/neoj4.service"; import { GraphModelService } from "./models/model.service"; import { Movie } from "src/graphql.schema"; @Resolver('Movie') export class GraphService { constructor(private

问题 First: Yes, I have Googled this beforehand, and the solution that came up isn't working for me. The Context I have an Angular 2 component that calls a service, and needs to perform some data manipulation once it receives the response: ngOnInit () { myService.getData() .then((data) => { this.myData = /* manipulate data */ ; }) .catch(console.error); } In its template, that data is passed to a child component: <child-component [myData]="myData"></child-component> This is causing an error that

问题 I'm using three tables from an associative relationship. The parent "products" has an id which is associated to the table RefProductOptions.productID. This works perfectly fine with my resolvers and GraphQL responds correctly. When I introduce the third table "productoptions" and I try to add an association layer between "refproductoptions.optionId" with "productoptions.id", the GraphQL look up fails. The GraphQL error message is: { "errors": [ { "message": "refproductoptions

问题 I am trying to write a custom Expression Language (EL) resolver. The purpose of this resolver is to intercept method calls to a certain Bean to add a second parameter. I have written a custom EL resolver that overwrites the invoke -method to do what I want. I also put the resolver in the faces-config.xml as required. Unfortunately, I have a dependency in my project that also declares custom EL Resolvers and they are placed before my EL resolver in the resolver chain. Since one of the other
