ClassFormatError：クラスファイルjavax / mail / MessagingExceptionのネイティブまたは抽象ではないメソッドのコードなし属性

Question

JavaMail apiを使用してSpring MVC Webアプリで電子メールを送信すると、奇妙なClassFormatErrorが表示されます。

以下は私のmail-cfg.xmlです

Answer 1

javax:javaee-apiは、単体テストを含む、実行ではなくコンパイルを目的としています。実行に適したクラスが必要な場合は、Java EEアプリケーションサーバーに対して実行します。

また、正しい名前は Java EE であり、[〜＃〜] jeeではありません[〜＃〜]。

Answer 2

私は同様の問題を抱えていました...ので、JUnitを実行しているときにエラーが発生しました：

Absent Code attribute in method that is not native or abstract in class file javax/servlet/http/HttpServlet

次の依存関係（最初の依存関係）を追加して解決します。

<dependency>
    <groupId>org.glassfish.main.extras</groupId>
    <artifactId>glassfish-embedded-all</artifactId>
    <version>3.1.2.2</version>
    <scope>test</scope>
</dependency>

Answer 3

クラスパスに複数の競合するJARがある場合、通常このエラーが発生します。より一般的な理由の1つは、アプリケーションコンテナによって提供されることになっているクラスパスにアーティファクトを含める場合です。 POMを見ると、冗長で重複する依存関係がいくつかあります。これらを削除します。

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>servlet-api</artifactId>
    <version>2.5</version>
    <scope>provided</scope>
</dependency>
<dependency>
    <groupId>javax.validation</groupId>
    <artifactId>validation-api</artifactId>
    <version>1.0.0.GA</version>
</dependency>
<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>jstl</artifactId>
    <version>1.2</version>
</dependency>
<dependency>
    <groupId>javax.mail</groupId>
    <artifactId>mail</artifactId>
    <version>1.4.3</version>
</dependency>
<dependency>
    <groupId>javaee</groupId>
    <artifactId>javaee-api</artifactId>
    <version>5</version>
</dependency>

そして、Java EE依存関係のスコープを 'provided'に変更します。

<dependency>
    <groupId>javax</groupId>
    <artifactId>javaee-api</artifactId>
    <version>6.0</version>
    <scope>provided</scope>
</dependency>

最後に、Java EE 6対応のWebサーバーにデプロイしていることを確認してください。エラーshouldはなくなります。

---編集---

Java 5準拠レベルにコンパイルしています。これを変更してください。

<configuration>
    <source>1.5</source>
    <target>1.5</target>
</configuration>

そして、ソースとターゲットの値を1.6にします。

Answer 4

Jmockとmavenを使用してjunitsを実行するときに、私も同じような例外に直面しました。

コンストラクターの例外：testDoExecute（Java.lang.ClassFormatError：Java.lang.ClassLoader.defineClass1（Native Method）のクラスファイルjavax/servlet/http/Cookieのネイティブまたは抽象ではないメソッドのAbsent Code属性

これは、コードがJavaEE6 APIやユニットテストのように不完全なクラスに対してコンパイルされるため、プロジェクトで使用されるjavaee api jarで利用できないコードがアクセスしようとするクラスが原因ですそこにないコードにアクセスします。 JUnitは単に失敗し、テストをエラーとしてマークし、上記の例外のようなものを出力します。

javax.servlet jar/dependencyを追加するか、以下に示すjavaee jarバージョンを変更することで解決できます。

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>servlet-api</artifactId>
    <version>2.5</version>
</dependency>

**OR** 

<dependency>
    <groupId>javax.j2ee</groupId>
    <artifactId>j2ee</artifactId>
    <version>1.4</version>
    <scope>provided</scope>
</dependency>

[〜＃〜] ps [〜＃〜]：プロジェクト内の他の既存のjarと互換性のあるjarバージョンを追加してください。
