使用streams对内部对象中的Map属性进行分组？

import java.util.List;
import java.util.Map;
import java.util.stream.Collectors;

public class GroupingExample {
    public static void main(String[] args) {
        List<YourObject> objects = getObjectList(); // 获取对象列表

        Map<String, List<YourObject>> groupedMap = objects.stream()
                .collect(Collectors.groupingBy(obj -> obj.getMapProperty()));

        // 打印分组结果
        groupedMap.forEach((key, value) -> System.out.println("Group: " + key + ", Objects: " + value));
    }

    // 自定义对象
    static class YourObject {
        private String mapProperty;

        public YourObject(String mapProperty) {
            this.mapProperty = mapProperty;
        }

        public String getMapProperty() {
            return mapProperty;
        }
    }

    // 获取对象列表的示例方法
    static List<YourObject> getObjectList() {
        // 返回对象列表的逻辑
    }
}
