在为Spring Data ElasticSearch 4.X生成的文档中禁用TypeHints

@Configuration
@EnableElasticsearchRepositories(basePackages = "com.example.repositories")
public class ElasticsearchConfig {

    @Bean
    public ElasticsearchOperations elasticsearchTemplate() {
        return new ElasticsearchTemplate(client(), new CustomElasticsearchConverter());
    }

    @Bean
    public Client client() {
        // 配置并返回Elasticsearch客户端
    }

    private static class CustomElasticsearchConverter extends AbstractElasticsearchConverter {

        @Override
        protected void configureTypeHints(TypeMapper typeMapper) {
            typeMapper.setWriteTypeHints(false);
        }
    }
}
