Spring数据弹性搜索 @Query @高亮显示

Question

我用这个查询代码不能得到高亮的字段，有什么想法吗，我用的是SDE4.0.0.RC2，我想用@Query。

@Query("{\n" +
           "  \"multi_match\": {\n" +
           "    \"query\": \"?0\",\n" +
           "    \"fields\": [\n" +
           "      \"code^2\",\n" +
           "      \"name\"\n" +
           "    ],\n" +
           "    \"analyzer\": \"standard\"\n" +
           "  }\n" +
           "}")
   @Highlight(
           fields = @HighlightField(
                   name = "['code','name']"),
           parameters = @HighlightParameters(
                   preTags = "<strong>",
                   postTags = "</strong>",
                   fragmentSize = 500,
                   numberOfFragments = 3
           )
   )
   List<CodeNames> findAllByCodeAndNameOrderByName(String code, Pageable pageable);

你需要在一个单独的注释参数中指定每个高亮区域。

   @Query("{\n" +
            "  \"multi_match\": {\n" +
            "    \"query\": \"?0\",\n" +
            "    \"fields\": [\n" +
            "      \"code^2\",\n" +
            "      \"name\"\n" +
            "    ],\n" +
            "    \"analyzer\": \"standard\"\n" +
            "  }\n" +
            "}")
    @Highlight(
        fields = {
            @HighlightField(name = "code"),
            @HighlightField(name = "name")
        },
        parameters = @HighlightParameters(
            preTags = "<strong>",
            postTags = "</strong>",
            fragmentSize = 500,
            numberOfFragments = 3
        )
    )
    List<CodeNames> findAllByCodeAndNameOrderByName(String code, Pageable pageable);

编辑。

除此之外，你还必须改变你的方法的返回类型。

List<SearchHit<CodeNames>> findAllByCodeAndNameOrderByName(String code, Pageable pageable);

或者

SearchHits<CodeNames> findAllByCodeAndNameOrderByName(String code, Pageable pageable);

的高亮值，以便能够从返回的 SearchHit见 https:/docs.spring.iospring-dataelasticsearchdocs4.0.0.RC2referencehtml#elasticsearch.operations.searchresulttypes。
