Question

我正在使用Elastic search Java API 2.4开发批量插入这是代码

    Client client = null;
    try
    {
        Settings settings = Settings.settingsBuilder().put("cluster.name", CLUSTER_NAME)
                .put("path.home", ELASTICSEARCH_PATH).build();
        client = NodeBuilder.nodeBuilder().settings(settings).node().client();
        CsvMapper csvMapper = new CsvMapper();
        CsvSchema csvSchema = CsvSchema.builder()
                .addColumn("code", CsvSchema.ColumnType.STRING)
                .addColumn("category", CsvSchema.ColumnType.STRING)
                .addColumn("name", CsvSchema.ColumnType.STRING)
                .addColumn("quantity", CsvSchema.ColumnType.NUMBER)
                .build()
                .withHeader();
        MappingIterator<OnlineProduct> onlineProductIter = csvMapper.readerFor(OnlineProduct.class).with(csvSchema)
                .readValues(new FileReader(sources[0]));
        BulkRequestBuilder bulkRequest = client.prepareBulk();
        while (onlineProductIter.hasNext())
        {
            OnlineProduct onlineProduct = onlineProductIter.nextValue();
            XContentBuilder json = jsonBuilder()
                    .startObject()
                    .field("code", onlineProduct.getCode())
                    .field("category", onlineProduct.getCategory())
                    .field("name", onlineProduct.getName())
                    .field("quantity", onlineProduct.getQuantity())
                    .endObject();
            bulkRequest.add(client.prepareIndex("onlineshop", "product")
                    .setSource(json));
        }
        BulkResponse bulkResponse = bulkRequest.execute().actionGet();

BulkResponse没有失败，但每个BulkItemResnonse都包含此堆栈跟踪

IndexResponse[index=onlineshop,type=product,id=AVddUhuw-JSq2gJmvjpI,version=1,created=true,shards=Error building toString out of XContent: com.fasterxml.jackson.core.JsonGenerationException: Can not write a field name, expecting a value

有没有人知道发生了什么？

尝试从弹性搜索依赖项中排除<groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-core</artifactId>。然后使用2.7.8版本单独添加jackson-core依赖项

我的pom.xml看起来：

    <dependency>
        <groupId>org.elasticsearch</groupId>
        <artifactId>elasticsearch</artifactId>
        <version>2.4.1</version>
        <exclusions>
            <exclusion>
                <groupId>com.fasterxml.jackson.core</groupId>
                <artifactId>jackson-core</artifactId>
            </exclusion>
        </exclusions>
    </dependency>

    <dependency>
        <groupId>com.fasterxml.jackson.core</groupId>
        <artifactId>jackson-core</artifactId>
        <version>2.7.8</version>
    </dependency>

希望这可以帮助你：）
