What is this Orchestration : Orchestration is the traditional way of handling interactions between different services in Service-Oriented Architecture (SOA). With orchestration process, there is typically one controller that acts as the “orchestrator” of the overall service interactions. This typically follows a request/response type pattern. For example, if three services needed to be called in a particular order, the orchestrator makes a call to each one, waiting for a response before calling the next. 

Filters are one of the important features provided by the JAX-RS framework. It is used in various contexts. It may be applied on either request to a resource or the response from a resource, or both.Consider a scenario in which we do not want to show some class members in the response. This process is called filtering. Jackson has two annotations that are used in filtering are:  @JsonIgnore  and  @JsonIgnoreProperties . @JsonIgnore  is used at field level to mark a property or list of properties to be ignored. import java . io .
