问题
我通过解压hanlp zip包到plugins目录下的方式去安装该插件，安装后重启，发现报错如下：
通过分析发现，在加载hanlp插件的时候，是去${ES_HOME}/config目录下加载hanlp.properties和hanlp-remote.xml文件，源代码如下：
private Dictionary(Configuration configuration) {
//去${ES_HOME}/config下的analysis_hanlp目录下加载配置文件
Path configDir = configuration.getEnvironment().configFile().resolve(AnalysisHanLPPlugin.PLUGIN_NAME);
Predefine.HANLP_PROPERTIES_PATH = configDir.resolve(CONFIG_FILE_NAME).toString();
logger.debug("hanlp properties path: {}", Predefine.HANLP_PROPERTIES_PATH);
DictionaryFileCache.configCachePath(configuration);
DictionaryFileCache.loadCache();
RemoteDictConfig.initial(configDir.resolve(REMOTE_CONFIG_FILE_NAME).toString());
}解决办法
第一种
将${hanlp_home}/config目录拷贝到${ES_HOME}/config/analysis_hanlp目录下,重启ES集群
第二种
修改代码，将加载hanlp配置文件的路径修改为${hanlp_home}/config
private Dictionary(Configuration configuration) {
# 从${hanlp_home}/config目录下加载
Path hanlpPluginConfigDir = configuration.getEnvironment().pluginsFile().resolve(AnalysisHanLPPlugin.PLUGIN_NAME + "/config");
Predefine.HANLP_PROPERTIES_PATH = hanlpPluginConfigDir.resolve(CONFIG_FILE_NAME).toString();
logger.debug("hanlp properties path: {}", Predefine.HANLP_PROPERTIES_PATH);
DictionaryFileCache.configCachePath(configuration);
DictionaryFileCache.loadCache();
RemoteDictConfig.initial(hanlpPluginConfigDir.resolve(REMOTE_CONFIG_FILE_NAME).toString());
