私は JDK 9 の Jigsaw モジュラー システムを調べてきました。
コマンドラインからコンパイルすると、非常にうまく機能します（少なくともクイックスタートはそうです）。
しかし、Spring と Jigsaw を使用して単純な REST API を作成しようとしています。Spring 5.0.0 M1にはあると言われています
2016 年 7 月時点の JDK 9 との完全な互換性
また、REST API を Maven と連携させたいと考えています。この Maven pageによると、Maven は Java 9 で動作するはずです (または、これを間違って読んでいますか?)。
JAVA_HOME が JDK を指している場合mvn spring-boot:run、Spring Boot アプリケーションで実行できないようです。次のような多くの例外がスローされます。
FoundError: javax/xml/bind/ValidationException
2016-09-14 10:43:42.704 ERROR 120408 --- [ main] o.s.boot.SpringApplication : Application startup failed
実行mvn -versionすると、次のようになります。
Apache Maven 3.3.9 (bb52d8502b132ec0a5a3f4c09453c07478323dc5; 2015-11-10T17:41:47+01:00)
Maven home: C:\Program Files\apache-maven-3.3.9\bin\..
Java version: 9-ea, vendor: Oracle Corporation
Java home: C:\Program Files\Java\jdk-9
Default locale: en_US, platform encoding: Cp1252
OS name: "windows 10", version: "10.0", arch: "amd64", family: "dos"
現在、Jigsaw を使用して Spring と Java 9 でこの REST API を作成することは可能ですか? それとも、2017 年 3 月または 7 月頃まで Java 8 に固執する必要がありますか?
