FluxMonoTestCase.java
package com.example.reactor; import lombok.extern.slf4j.Slf4j; import org.junit.jupiter.api.Test; import reactor.core.publisher.Flux; import reactor.core.publisher.Mono; import java.util.Map; @Slf4j public class FluxMonoTestCase extends BaseTestCase { @Test public void collectMap(){ Flux<Employee> employeeFlux = Flux.fromIterable(list); //转换HashMap Mono<Map<String,Employee>> mono = employeeFlux .collectMap(key ->key.getName(),val ->val); mono.subscribe(System.out::println); } }
BaseTestCase.java
package com.example.reactor; import java.util.Arrays; import java.util.List; public class BaseTestCase { protected static final List<Employee> list = Arrays.asList( new Employee(1, "Alex", 1000), new Employee(2, "Michael", 2000), new Employee(3, "Jack", 1500), new Employee(4, "Owen", 1500), new Employee(5, "Denny", 2000)); }
结果:
{Alex=Employee(id=1, name=Alex, salary=1000.0), Owen=Employee(id=4, name=Owen, salary=1500.0), Denny=Employee(id=5, name=Denny, salary=2000.0), Michael=Employee(id=2, name=Michael, salary=2000.0), Jack=Employee(id=3, name=Jack, salary=1500.0)}
