记录elasticsearch-analysis-dynamic-synonym从8.7.0升级到8.15.0所遇到的问题
一、问题伊始
今天打算用elasticsearch最新版本来学点东西，发现安装es插件就遇到了许多问题，于是便通过此篇博客来记录问题的整个过程。
去年我学习用的elasticsearch版本为8.7.0，当时GitHub有一个大佬直接升级到了8.7.1，我只需要改改版本号重新打个包就行啦，根本就没考虑那么多问题。但是今年我想要用最新版本8.15.0来搞点事情，就不得不面对升级问题啦。
首先我先说问题，我这次照常，将elasticsearch-analysis-dynamic-synonym项目的pom中的版本号从8.7.0修改为8.15.0，打包过程中并未出现问题，但是安装到es的plugins目录之后重启es，无法建立关于同义词的索引结构，这下可就让我犯了难，kibana控制台一直出现下面的内容，这使得我去看了一下elasticsearch-analysis-dynamic-synonym的源码。
"Call createPerAnalyzerSynonymGraphFactory to specialize this factory for an analysis chain first"
我定位到了TokenStream create(TokenStream tokenStream)这个方法，但是并没有看出什么实质性的问题。

二、大脑开窍
于是我开始思考，8.7.0和8.15.0究竟有什么区别呢？8.7.0不会报错，而8.15.0会报下面的错误。
java.lang.IllegalStateException: Call getChainAwareTokenFilterFactory to specialize this factory for an analysis chain first at com.bellszhu.elasticsearch.plugin.synonym.analysis.DynamicSynonymTokenFilterFactory.create(DynamicSynonymTokenFilterFactory.java:85) at org.elasticsearch.index.analysis.CustomAnalyzer.createComponents(CustomAnalyzer.java:86) at org.apache.lucene.analysis.AnalyzerWrapper.createComponents(AnalyzerWrapper.java:120) at org.apache.lucene.analysis.Analyzer.tokenStream(Analyzer.java:193) at org.elasticsearch.index.analysis.AnalysisRegistry.checkVersions(AnalysisRegistry.java:769) at org.elasticsearch.index.analysis.AnalysisRegistry.produceAnalyzer(AnalysisRegistry.java:732) at org.elasticsearch.index.analysis.AnalysisRegistry.build(AnalysisRegistry.java:615) at org.elasticsearch.index.analysis.AnalysisRegistry.build(AnalysisRegistry.java:213) at org.elasticsearch.index.IndexModule.newIndexService(IndexModule.java:510) at org.elasticsearch.indices.IndicesService.createIndexService(IndicesService.java:759) at org.elasticsearch.indices.IndicesService.withTempIndexService(IndicesService.java:702) at org.elasticsearch.cluster.metadata.MetadataCreateIndexService.applyCreateIndexWithTemporaryService(MetadataCreateIndexService.java:476) at org.elasticsearch.cluster.metadata.MetadataCreateIndexService.applyCreateIndexRequestWithV1Templates(MetadataCreateIndexService.java:600) at org.elasticsearch.cluster.metadata.MetadataCreateIndexService.applyCreateIndexRequest(MetadataCreateIndexService.java:424) at org.elasticsearch.cluster.metadata.MetadataCreateIndexService$1.execute(MetadataCreateIndexService.java:303) at org.elasticsearch.cluster.service.MasterService$UnbatchedExecutor.execute(MasterService.java:569) at org.elasticsearch.cluster.service.MasterService.innerExecuteTasks(MasterService.java:1070) at org.elasticsearch.cluster.service.MasterService.executeTasks(MasterService.java:1033) at org.elasticsearch.cluster.service.MasterService.executeAndPublishBatch(MasterService.java:233) at org.elasticsearch.cluster.service.MasterService$BatchingTaskQueue$Processor.lambda$run$2(MasterService.java:1686) at org.elasticsearch.action.ActionListener.run(ActionListener.java:444) at org.elasticsearch.cluster.service.MasterService$BatchingTaskQueue$Processor.run(MasterService.java:1683) at org.elasticsearch.cluster.service.MasterService$5.lambda$doRun$0(MasterService.java:1278) at org.elasticsearch.action.ActionListener.run(ActionListener.java:444) at org.elasticsearch.cluster.service.MasterService$5.doRun(MasterService.java:1257) at org.elasticsearch.common.util.concurrent.ThreadContext$ContextPreservingAbstractRunnable.doRun(ThreadContext.java:984) at org.elasticsearch.common.util.concurrent.AbstractRunnable.run(AbstractRunnable.java:26) at java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1144) at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:642) at java.base/java.lang.Thread.run(Thread.java:1583)
我开始有意识想尝试将这两个版本的代码进行对比，但是这过程中的代码对比差别太大了，就算用idea的compare工具对比也太伤身体了，于是我直接把这段错误丢给了ChatGPT，它给了我一个建议，让我去看看吧AnalysisRegistry 8.7.0.java和AnalysisRegistry 8.15.0.java这两类的差异，于是我通过调试弄到了这两个类的详细信息，并且又丢给了ChatGPT，让它帮我干活，找出问题所在，它告诉我有可能是发生在checkVersions附近，于是我用idea的compare工具对比，果然发现了问题，原来8.15.0在调用getChainAwareTokenFilterFactory方法上新增了一个IndexService.IndexCreationContext context参数，而elasticsearch-analysis-dynamic-synonym的写的getChainAwareTokenFilterFactory没有这个参数，于是我尝试在getChainAwareTokenFilterFactory周围加上这个参数，不出意外，打包重新es果然就能跑起来了。
三、运行结果
PUT dynamic_synonym_index
{
"settings": {
"number_of_shards": 2,
"number_of_replicas": 1,
"index": {
"analysis": {
"filter": {
"mysql_synonym": {
"type": "dynamic_synonym",
"synonyms_path": "MySql",
"interval": 30
}
},
"analyzer": {
"ik_synonym_smart": {
"type": "custom",
"tokenizer": "ik_smart",
"filter": [
"mysql_synonym"
]
},
"ik_synonym_max": {
"type": "custom",
"tokenizer": "ik_max_word",
"filter": [
"mysql_synonym"
]
}
}
}
}
}
}
返回下面的结果
{
"acknowledged": true,
"shards_acknowledged": true,
"index": "dynamic_synonym_index"
}
但是解决了插件问题之后，我又遇到了新的问题，插件连接不上MySQL了，后面解决了这个问题再出一个博客记录一下。
附录
方便后面吹牛逼，先记录一下这两个文件，可以看到两个版本的getChainAwareTokenFilterFactory确实是有差异的，新版本多了一个IndexService.IndexCreationContext context参数
