名称为'Lucene54'的org.apache.lucene.codecs.Codec类型的SPI类不存在 [英] An SPI class of type org.apache.lucene.codecs.Codec with name 'Lucene54' does not exist

问题描述

使用lucene-core-5.5.2，我在weblogic服务器中遇到问题a.独立搜索应用程序可以运行，但是当我作为WEB APP部署时却失败，并出现以下错误

Exception type is 'java.lang.ExceptionInInitializerError'. Runtime error: java.lang.IllegalArgumentException: An SPI class of type org.apache.lucene.codecs.Codec with name 'Lucene54' does not exist. You need to add the corresponding JAR file supporting this SPI to your classpath. The current classpath supports the following names: []

我尝试在classes/下创建文件夹结构，因为META-INF/services/添加了lucene-core-5.5.2.jar META-INF\services\目录中的所有文件，还创建了META-INF\services\的jar文件并添加到类路径中，但无法识别META-INF/services来加载SPI

任何帮助将不胜感激.

中添加以下文件

文件夹:META-INF/services/

With lucene-core-5.5.2 i am facing problem a in weblogic server. standalone search application works but when i deploy as WEB APP it is failing with below error

Exception type is 'java.lang.ExceptionInInitializerError'. Runtime error: java.lang.IllegalArgumentException: An SPI class of type org.apache.lucene.codecs.Codec with name 'Lucene54' does not exist. You need to add the corresponding JAR file supporting this SPI to your classpath. The current classpath supports the following names: []

I tried creating folder structure under classes/ as META-INF/services/ added all files from lucene-core-5.5.2.jar META-INF\services\ directory also created jar file for META-INF\services\ and added in classpath but it doesn't recognize META-INF/services to load SPI

Any help would be really appreciated.
