java - 将 Lucene 与 H2 数据库结合使用时出错

Question

我想在我的项目中实现一个使用 H2 数据库(嵌入式)的小型全文搜索。据我所知，我必须使用 Lucene 作为全文引擎来查找相关结果(不仅仅是包含结果)。但我不能使用它。该 block 是Lucene初始化:

FullTextLucene.init(connection);
FullTextLucene.createIndex(connection, "PUBLIC", Tables.COURSES_DETAIL, Columns.NAME);

我也用过这种方式:

  stmt.execute(
      "create alias if not exists FTL_INIT for \"org.h2.fulltext.FullTextLucene.init\"");
  stmt.execute("call FTL_INIT()");
  stmt.execute(
      String.format("CALL FTL_CREATE_INDEX('PUBLIC','%s',%s)", Tables.COURSES_DETAIL, "NULL"));

但是这个错误发生在运行时:

Error creating or initializing trigger "FTL_COURSES_DETAIL" object, class "org.h2.fulltext.FullTextLucene$FullTextTrigger", cause: "org.h2.message.DbException: Class ""org.h2.fulltext.FullTextLucene$FullTextTrigger"" not found [90086-197]"; see root cause for details; SQL statement:
CREATE TRIGGER IF NOT EXISTS "PUBLIC"."FTL_COURSES_DETAIL" AFTER INSERT, UPDATE, DELETE, ROLLBACK ON "PUBLIC"."COURSES_DETAIL" FOR EACH ROW CALL "org.h2.fulltext.FullTextLucene$FullTextTrigger"

在我将 H2 库降级到最新的“稳定”版本(1.4.196)后，错误已更改:

Caused by: java.lang.NoSuchMethodError: org.apache.lucene.store.FSDirectory.open(Ljava/io/File;)Lorg/apache/lucene/store/FSDirectory;

有时会出现此错误:

Exception calling user-defined function: "init(conn1: url=jdbc:default:connection user=INFC): org.apache.lucene.store.FSDirectory.open(Ljava/io/File;)Lorg/apache/lucene/store/FSDirectory;"; SQL statement:
call FTL_INIT()

Answer 1

我找到了解决方案。但我知道这不是最好的。

我将 Lucene lib 降级到 3.6.2 并使用普通查询而不是 FullTextLucene 函数。
