springboot整合elasticsearch8.12.0遇到的问题

1.java.lang.noclassdeffounderror: com/fasterxml/jackson/core/util/jacksonfeature
在官方文档里要引入以下依赖

		<dependency>
            <groupId>co.elastic.clients</groupId>
            <artifactId>elasticsearch-java</artifactId>
            <version>8.12.0</version>
        </dependency>
        <dependency>
            <groupId>com.fasterxml.jackson.core</groupId>
            <artifactId>jackson-databind</artifactId>
            <version>2.12.3</version>
        </dependency>

但会报错：java.lang.noclassdeffounderror: com/fasterxml/jackson/core/util/jacksonfeature
是因为没有导入jackson-core依赖，jackson-core的JacksonFeature依赖在jackson- core2.12.0之后的版本才引入，这里的依赖版本是2.11.4，所以我们要重新导入

		<dependency>
            <groupId>com.fasterxml.jackson.core</groupId>
            <artifactId>jackson-databind</artifactId>
            <version>2.12.3</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>2.12.3</version>
        </dependency>

2.Caused by: java.lang.NoSuchMethodError: ‘org.elasticsearch.client.RequestOptions$Builder org.elasticsearch.client.RequestOptions$Builder.setHttpAsyncResponseConsumerFactory(org.elasticsearch.client.HttpAsyncResponseConsumerFactory)’
查看maven,发现elasticsearch-rest-client这个版本不是8.12.0，所以我们需要重新导入这个

		<dependency>
            <groupId>org.elasticsearch.client</groupId>
            <artifactId>elasticsearch-rest-client</artifactId>
            <version>8.12.0</version>
        </dependency>
