设置RequestOptions

框架内置默认使用的是RestHighLevelClient的默认RequestOptions,即RequestOptions.DEFAULT,在大多数场景下,使用默认的RequestOptions是OK的,但是有极个别个性化的使用场下,需要对其进行个性化设置,才能满足业务需求. 例如查询某些超大字段时报错: "entity content is too long [168583249] for the configured buffer limit [104857600]",此时就可以通过自定义RequestOptions来调大缓冲区.

API

    // 设置当前mapper的RequestOptions 设置后永驻jvm缓存,后续CRUD均使用该RequestOptions, 重启项目才失效
    Boolean setRequestOptions(RequestOptions requestOptions);

##使用

    @Test
    public void testSetRequestOptions() {
        // 此案例仅供参考,实际可按业务需要自定义拓展
        RequestOptions.Builder options = RequestOptions.DEFAULT.toBuilder();
        options.setHttpAsyncResponseConsumerFactory(new HttpAsyncResponseConsumerFactory.HeapBufferedResponseConsumerFactory(4 * 104857600));
        final RequestOptions requestOptions = options.build();
        documentMapper.setRequestOptions(requestOptions);
    }

温馨提示

不设置则使用默认的RequestOptions.DEFAULT,设置后则针对当前mapper全局生效,如有多个mapper,可按业务场景按需设置
