我有以下存储库:
public interface MyRepository extends MongoRepository<MyDocument, String>, QueryDslPredicateExecutor<MyDocument>{ ...
我写了一个为我提供一些谓词的类,一个是在两个ZonedDateTimes的时间帧之间进行搜索
public static Predicate hasTimeBeetween(final ZonedDateTime from, final ZonedDateTime to) {
return QMyDocument.myDocument.remoteTime.between(from, to);
}
如果我在没有该谓词的情况下调用findAll方法,如果我按如下方式添加谓词,则一切正常
ZonedDateTime now = ZonedDateTime.now();
MyDocument cNow = this.createInDatabase(this.createDocumentInDatabase(now));
Iterable<CrudNut> findAll = this.repository.findAll(CrudNutPredicates.hasTimeBeetween(now.minusDays(1), now.plusDays(1)));
我遇到以下例外:

我理解异常并且缺少编解码器但不知道如何解决这个问题。有人可以帮帮我吗?
答案 0 :(得分:1)
我的申请中遇到了类似的问题。
我没有在之间使用ComparableExpression ,而是使用了后的Temporal expressions 和之前的 AND。
尝试以下操作(您可能需要添加一些空检查):
public static Predicate hasTimeBeetween(final ZonedDateTime from, final ZonedDateTime to) {
BooleanBuilder builder = new BooleanBuilder();
builder.and(QMyDocument.myDocument.remoteTime.after(from));
builder.and(QMyDocument.myDocument.remoteTime.before(to));
return builder.getValue();
}
