Writing Integration Test of ExpressionVisitor with Olingo / ODATA 4

阅读更多关于 Writing Integration Test of ExpressionVisitor with Olingo / ODATA 4

问题 I'm implementing a web service respecting version 4 of the OData standard in Java language with the framework Olingo. I need to customize the response of $filter . I've implemented a Visitor as documented in the quick start. I need to implement an integration Test to try a different kind of grammar and to prevent regression bug in case of future maintenance. For the V2, I found the following tutorial and the following code : @Test public void printExpressionWithProperty() throws Exception { /

Why is $expand not working correct in my JPA/Olingo project

阅读更多关于 Why is $expand not working correct in my JPA/Olingo project

问题 I am currently working on a JPA/Olingo based odata service. The Olingo version used is 2.0.7. The JPA implementation used is eclipselink version 2.5.1. There are two entities connected through a OneToMany relationship (Company, Page). Requesting the company from the service (e.g. /odata/v2/Companies) without an $expand works fine. The same for requesting the pages. Requesting pages and expanding the CompanyDetails works fine as well. Somehow requesting the company and expanding the associated

阅读更多关于 How to create a bounded action in Olingo V4 (java)

问题 I have tried looking everywhere but couldn't figure out how to implement bounded actions in olingo V4 java. Everywhere unbounded action tutorial is given. I tried tweaking this code. final CsdlAction action = new CsdlAction(); action.setName("testAction"); action.setBound(true); This gives me error when I try to access $metadata API. If anyone can point me towards a good tutorial on how to go about it then it would be great. 回答1: I looked into the source code of olingo and debugged their code

How can I consume an OData4 service in Java using either Olingo or the SDL OData Framework

阅读更多关于 How can I consume an OData4 service in Java using either Olingo or the SDL OData Framework

问题 I need to consume an OData4 service from Java and based on the list of frameworks on the OData website the two choices are Olingo or the SDL Odata Framework. My problem is that the documentation for both of these projects are focused on writing a service not consuming one. The Olingo site links to a blog post from 2014 which is not API compatible with the current version and I couldn't find anything on the SDL github pages. If someone could just provide me with a simple POST / GET example

Olingo - Create strongly typed POJOs for client library of OData service

阅读更多关于 Olingo - Create strongly typed POJOs for client library of OData service

I'm using Apache Olingo as an OData client for a Java SDK that I will provide for a RESTful OData API. In the SDK I want to be able to have strongly typed classes to represent the OData entities. I'm having trouble implementing this easily and thus feel like I'm missing a different strategy here. The Olingo way seems to be to get an ODataClient object which provides the user with a bunch of useful methods for interacting with the API. The ODataClient is using a bunch of factory methods to build my request. For instance, this is the code I used to get the Customers from the Northwind sample
