Я пытаюсь сгенерировать запрос динамически на основе входных данных, но в сгенерированном запросе я вижу, что генерируются только две агрегации. Как я могу сделать так, чтобы в каждом поле были отдельные агрегации ниже, это код, который я пробовал, и ответ, что я получаю.
Из main () я звоню
buildSearchCriteria("1");
Здесь я устанавливаю тип агрегации и соответствующие значения:
public static void buildSearchCriteria(String... exceptionId) {
SearchCriteria searchCriteria = new SearchCriteria();
Map<String, List<FieldNameAndPath>> stringListMap = new HashMap<>();
stringListMap.put("nested", asList(new FieldNameAndPath("nested", "recommendations",
"recommendations", null, emptyList(), 1)));
stringListMap.put("filter", asList(new FieldNameAndPath("filter", "exceptionIds", "recommendations.exceptionId.keyword",
asList(exceptionId),
asList(new NestedAggsFields("terms", "exceptionIdsMatch")), 2)));
stringListMap.put("terms", asList(new FieldNameAndPath("terms", "by_exceptionId", "recommendations.exceptionId.keyword", null, emptyList(), 3),
new FieldNameAndPath("terms", "by_item", "recommendations.item.keyword", null, emptyList(), 4),
new FieldNameAndPath("terms", "by_destination", "recommendations.location.keyword", null, emptyList(), 5),
new FieldNameAndPath("terms", "by_trans", "recommendations.transportMode.keyword", null, emptyList(), 6),
new FieldNameAndPath("terms", "by_sourcelocation", "recommendations.sourceLocation.keyword", null, emptyList(), 7),
new FieldNameAndPath("terms", "by_shipdate", "recommendations.shipDate", null, emptyList(), 8),
new FieldNameAndPath("terms", "by_arrival", "recommendations.arrivalDate", null, emptyList(), 9)));
stringListMap.put("sum", asList(new FieldNameAndPath("sum", "quantity", "recommendations.transferQuantity", null, emptyList(), 10),
new FieldNameAndPath("sum", "transfercost", "recommendations.transferCost", null, emptyList(), 11),
new FieldNameAndPath("sum", "revenueRecovered", "recommendations.revenueRecovered", null, emptyList(), 12)));
System.out.println(stringListMap);
searchCriteria.setStringListMap(stringListMap);
aggregate(searchCriteria);
}
Ниже приведена функция агрегирования, которая будет получить вышеуказанную информацию и запрос о сборках:
public static void aggregate(SearchCriteria searchCriteria) throws IOException {
Map<String, List<FieldNameAndPath>> map = searchCriteria.getStringListMap();
List<FieldNameAndPath> nesteds = map.get("nested");
List<FieldNameAndPath> filter = map.get("filter");
List<FieldNameAndPath> terms = map.get("terms");
List<FieldNameAndPath> sums = map.get("sum");
SearchSourceBuilder sourceBuilder = new SearchSourceBuilder();
AggregationBuilder aggregationBuilder = new SamplerAggregationBuilder("parent");
nesteds.stream().forEach(l -> buildAggregations(l, aggregationBuilder));
filter.stream().forEach(l -> buildAggregations(l, aggregationBuilder));
terms.stream().forEach(l -> buildAggregations(l, aggregationBuilder));
sums.stream().forEach(l -> buildAggregations(l, aggregationBuilder));
SearchRequest searchRequest = new SearchRequest();
searchRequest.indices("index");
searchRequest.types("type");
sourceBuilder.aggregation(aggregationBuilder);
searchRequest.source(sourceBuilder);
System.out.println(searchRequest.source().toString());
}
метод buildAggregations:
private static AggregationBuilder buildAggregations(FieldNameAndPath fieldNameAndPath , AggregationBuilder parentAggregationBuilder) {
if(fieldNameAndPath.getAggType().equals("nested")){
parentAggregationBuilder = AggregationBuilders.nested(fieldNameAndPath.getFieldName(), fieldNameAndPath.getFieldPath());
}
if(fieldNameAndPath.getAggType().equals("filter")){
parentAggregationBuilder.subAggregation(AggregationBuilders
.filter(fieldNameAndPath.getFieldName(),
QueryBuilders.termsQuery(fieldNameAndPath.getNestedAggs()
.stream().map(nestedAggsFields -> nestedAggsFields.getFieldName()).findFirst().get(), fieldNameAndPath.getFieldValues())));
}
if(fieldNameAndPath.getAggType().equals("terms")){
parentAggregationBuilder.subAggregation(AggregationBuilders.terms(fieldNameAndPath.getFieldName())
.field(fieldNameAndPath.getFieldPath()));
}
if(fieldNameAndPath.getAggType().equals("sum")){
parentAggregationBuilder.subAggregation(AggregationBuilders.
sum(fieldNameAndPath.getFieldName()).field(fieldNameAndPath.getFieldPath()));
}
return parentAggregationBuilder;
}
Класс SearchCriteria:
@Data
public class SearchCriteria {
Map<String, List<FieldNameAndPath>> stringListMap;
private List<String> searchFields;
}
И поле DTO FieldNameAndPath:
public class FieldNameAndPath{
private String aggType;
private String fieldName;
private String fieldPath;
private List<String> fieldValues;
private List<NestedAggsFields> nestedAggs;
private int order;
}
