Elasticsearch - 升级到 2.1.1 后搜索失败

Question

我正在使用嵌入式 Elasticsearch 开发 Java EE 7 WebApplication（在 wildfly 10 中运行）。 升级到 elasticsearch 2.1.1 后，搜索不再起作用。 （索引似乎工作）

有效的依赖项：

    <dependency>
        <groupId>org.elasticsearch</groupId>
        <artifactId>elasticsearch</artifactId>
        <version>2.0.2</version>
    </dependency>
    <dependency>
        <groupId>org.apache.lucene</groupId>
        <artifactId>lucene-core</artifactId>
        <version>5.2.1</version>
    </dependency>

升级的依赖：

    <dependency>
        <groupId>org.elasticsearch</groupId>
        <artifactId>elasticsearch</artifactId>
        <version>2.1.1</version>
    </dependency>
    <dependency>
        <groupId>org.apache.lucene</groupId>
        <artifactId>lucene-core</artifactId>
        <version>5.3.1</version>
    </dependency>

索引一个非常基本的文档（索引似乎工作）后，搜索失败，并出现以下异常：

这就是我的搜索结果：

QueryStringQueryBuilder qb = QueryBuilders.queryStringQuery(queryString);
SearchResponse searchResponse = this.client.prepareSearch(INDEX_NAME)
            .setTypes(typeName)
            .setSearchType(SearchType.DFS_QUERY_THEN_FETCH)
            .setQuery(qb)
            .setFrom(offset)
            .setSize(limit)
            .execute()
            .actionGet();

Answer 1

我通过对 elasticsearch 依赖项进行着色解决了这个问题

1。我创建了一个单独的 Maven 模块：

<project>
...
<dependencies>
    <dependency>
        <groupId>org.elasticsearch</groupId>
        <artifactId>elasticsearch</artifactId>
        <version>2.3.4</version>
    </dependency>
</dependencies>

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-shade-plugin</artifactId>
            <version>2.4.1</version>
            <executions>
                <execution>
                    <phase>package</phase>
                    <goals>
                        <goal>shade</goal>
                    </goals>
                    <configuration>
                        <relocations>
                            <relocation>
                                <pattern>com.fasterxml.jackson</pattern>
                                <shadedPattern>shaded.elasticsearch.jackson</shadedPattern>
                            </relocation>
                        </relocations>
                        <transformers>
                            <transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer" />
                        </transformers>
                    </configuration>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>
...
</project>

2。然后将该模块用作我的主项目中的依赖项

    <dependency>
        <groupId>drivve</groupId>
        <artifactId>elasticsearch-shaded</artifactId>
        <version>1.0-SNAPSHOT</version>
    </dependency>
    <dependency>
        <groupId>org.apache.lucene</groupId>
        <artifactId>lucene-core</artifactId>
        <version>5.5.0</version><!-- be sure to match the version required by elasticsearch-shaded -->
    </dependency>

现在一切正常，管理起来并不难。 更多关于 shading es 依赖的信息可以在here找到。
