**I looked through the previous problem records, and my question should be: does the latest javaapi support custom tokenizer**

Excuse me, I have some questions about the Java client. I need to register setting in elastic that supports the "pinyin" plug-in. When I write this, I find that the plug-in cannot be configured. What should I do?

```auto
Reader pinyinJson = new StringReader(
                    "{\n" +
                            " \"type\": \"pinyin\",\n" +
                            " \"keep_separate_first_letter\": false,\n" +
                            " \"keep_full_pinyin\": true,\n" +
                            " \"keep_original\": true,\n" +
                            " \"limit_first_letter_length\": 16,\n" +
                            " \"lowercase\": true,\n" +
                            " \"remove_duplicated_term\": true\n" +
                            "}"
            );
            tokenizerMap.put("pinyin_tokenizer", new Tokenizer.Builder() //<---this
                    .definition(new TokenizerDefinition.Builder()
                            .withJson(pinyinJson).build()).build());

CreateIndexResponse createIndexResponse = elasticClient.indices().create(c -> c
                    .index(index)
                    .aliases(aliases, a -> a
                            .isWriteIndex(true))
                    .settings(s -> s
                            .analysis(a -> a
                                    .filter(filterMap)
                                    .normalizer(normalizerMap)
                                    .analyzer(analyzerMap)
                                    .tokenizer(tokenizerMap))
                            .numberOfShards("1")
                            .numberOfReplicas("1"))
                    .mappings(typeMapping));

```

The error message is

```auto
