我的代码有问题。

我粘贴在我的DAO界面下面：

public interface EventDao extends CrudRepository<Event, Integer>{

        import java.util.TimeZone;

        public class ActionStatistics {

            private String actionname;
            private long time;
            private String timeString;

            public ActionStatistics() {
                this.actionname = "actionname";
                this.time = 0;
            }

            public ActionStatistics(String actionname, long time) {
                this.actionname …
