Class RequestContextExecutor

java.lang.Object

com.sap.cloud.sdk.cloudplatform.servlet.BaseRequestContextExecutor<RequestContextExecutor>

com.sap.cloud.sdk.cloudplatform.servlet.RequestContextExecutor

public class RequestContextExecutor
extends BaseRequestContextExecutor<RequestContextExecutor>

Executes a Callable or Executable within a RequestContext.

Usually, a RequestContext is initialized by a RequestContextServletFilter. However, for tasks that are not triggered by a request (such as background jobs), the servlet filter is not executed. Therefore, in such cases, this class provides a wrapper that initializes the required RequestContext.

For example:

 new RequestContextExecutor().execute(() -> {
     // code that is executed within the RequestContext created by RequestContextExecutor
     new MyODataService().getAllEntities().top(10).execute();
 });
 
 

Note: Please be aware that if you pass a RequestContext to the executor, you have to make sure that this context is not destroyed during execution, for example, within asynchronous tasks. You should therefore only pass a RequestContext for which you manage the lifecycle yourself. In addition, you have to consider that an already existing RequestContext would result in an exception since nesting of RequestContexts is not allowed by default. You would have to allow this behavior using BaseRequestContextExecutor.withParentRequestContext().
