CXF 2.7.5 経由で RESTful サービスを構築しており、cxf-servlet アプローチを使用しています。javax-servlet 3.0 API、Spring 3.x、および Hibernate 4.x はすべて全体像の一部です。
Spring JPA、Spring ORM、および Hibernate を Maven POM ファイルに組み込む前に、明確に定義された (JAX-RS によって確立された) エンドポインを実際に提供する war ファイルを作成することができました。
いずれにせよ、war ファイルは Tomcat 7.x にデプロイされなくなりました。代わりに、タイトルに示されている例外が発生します。
java.lang.ClassNotFoundException: org.springframework.asm.ClassVisitor
私がすでにチェックしたいくつかのこと:
- Tomcat 7.x は、javax-servlet 3.x 準拠の API で実行されています。
- ClassVisitor を含むパッケージ (org.springframework.asm) は、WEB-INF/lib 内の jar ファイルの中で一意にリストされます。実際、現在は spring-core の一部としてダウンロードされています。
同様の状況を説明する多くの記事を閲覧しました。しかし、ほとんどの場合、クラスパスで ClassVisitor が参照されていることを確認してください。
私の POM ファイル (一番上にいくつかの例外を加えたもの) と、war ファイルの web.xml デプロイメント記述子、および applicationContext.xml をリストしています。一番下に、コンテキストとともに例外を再リストしました。
