Annotation Interface ConditionalOnTrajectory

@Retention(RUNTIME) @Target(METHOD) public @interface ConditionalOnTrajectory
This annotation helps to replace service references with new ones. Let us say, we have a service reference in spring defined as "testService" We want to replace this service reference with "testService1" but only if the trajectory id = "t1" You can then use this annotation to accomplish this. 

  // original service that needs to be replaced.
  @Bean public TestService testService(){ return new TestServiceImpl(); }
  // replace with this new service only for trajectory id "t1"
  @Bean @ConditionalOnTrajectory(id = "t1", service = "testService")
  public TestService testService1(){ return new TestServiceImpl1();}
 
 The code above replaces all instances of TestServiceImpl with TestServiceImpl1 but will do so only
 for trajectory ID "t1"
