将反应过滤器包含到反应器链中
Include reactive filter to reactor chain
我有一个 Flux 对象,我需要使用反应式方法过滤它们。由于 filter
不支持响应类型,我该如何实现?
Flux<Student> students = ...
students
.filter(this::leavesNearby)
.collectList();
Mono<Boolean> leavesNearby(Student student) {
Address address = student.getAddress;
return addressService.isNearby(address);
}
考虑到addressService.isNearby(address)
returnsMono<Boolean>
,我在这一行有一个编译错误filter(this::leavesNearby)
您可以使用 filterWhen
:
students
.filterWhen(this::leavesNearby)
.collectList();
