我在一个类中有两个测试，每个测试都包含以下查询：

SearchQuery searchQuery = new NativeSearchQueryBuilder().withQuery(matchAllQuery()).withFilter(rangeFilter("publishDate").lt(date)).build();

在其中一项测试中，结果的数量elasticsearchTemplate.count(searchQuery, Article.class)，在另一项中，验证返回值elasticsearchTemplate.queryForPage(searchQuery,Article.class)

如果我分别运行这两个测试中的任何一个，测试总是通过，一切似乎都很完美。 如果我因此同时运行这两个测试，一个接一个，第一个通过，另一个失败并出现SearchPhaseExecutionException：无法执行阶段...嵌套：NumberFormatException [对于输入字符串：“2015-02-01T00： 02:02.396Z"]...

更奇怪的是，这种行为仅在应用了 publishDate 的范围过滤器（具有类型：FieldType.Date）时才会出现。因此，当使用 boolFilter、termFilter 等其他类似查询时，所有测试都通过。

此外，如果我在同一个方法中运行这两个查询：不会引发异常。

我认为不正确的缓存初始化/清理可能会导致这种行为......但是，为什么其他查询也不会发生？

此外，在类的 @After 方法中，我删除了所有索引 (elasticsearchTemplate.deleteIndex(Article.class))，在 @Before 方法中，我执行/重做批量索引和刷新。

我走错路了吗？我在这里想念什么？

文章索引的映射：

@Document(indexName = "articles", type = "article", shards = 1, replicas = 0, refreshInterval = "-1", indexStoreType = "memory")
public class Article {
@Id
private Long id;
@Field(type = FieldType.String, store = true)
private String title;
@Field(type = FieldType.String, store = true)
private String text;
@Field(type = FieldType.String, store = true)
private String author;
@Field(type = FieldType.Date, store = true)
private Date publishDate;
@Field(type = FieldType.Date, store = true)
private Date lastModificationDate;
....
}

由于异常抱怨 a NumberFormatException，您应该尝试将日期作为 long （而不是 Date 对象）发送，因为这是内部存储日期的方式。请参阅我date.getTime()在下面的代码中调用：

SearchQuery searchQuery = new NativeSearchQueryBuilder()
    .withQuery(matchAllQuery())
    .withFilter(rangeFilter("publishDate").lt(date.getTime())).build();

我也找到了另一个解决方案。

在@Before方法中，我没有应用显式映射，这意味着不考虑索引中的@Field注释。Article实际上，使用了默认映射。

通过添加显式映射：

elasticsearchTemplate.putMapping(Article.class)

typeforpublishDate取自索引定义：

@Field(type = FieldType.Date, store = true)
private Date publishDate;

通过这种方式，所有测试都通过了，无论是单独运行它们还是按顺序运行它们。

此外，该rangeFilter参数也适用于初始参数date type。（当然，它也适用long type。）
