SpringBoot爲java9使用拼圖模塊

我想寫一個簡單的彈簧啓動應用程序，我可以使用Java 9運行。我無法在jdk9下編譯此應用程序。我在記錄模塊周圍出現一堆錯誤SpringBoot爲java9使用拼圖模塊

有沒有人有任何使用jdk9拼圖概念下的Springboot的示例應用程序？

請閱讀有關如何提出一個好問題的常見問題 - https://stackoverflow.com/help/how-to-ask。一些明顯的問題：您使用的是什麼版本的Maven？你可以分享pom.xml嗎？你在使用什麼版本的Spring Boot？ –

它看起來像：

所有JAR最終模塊路徑（怪異）
spring.jcl和jcl.over.slf4j上包含很多相同的包裹

如果您無法修復1.，請嘗試解決2.通過排除兩個工件之一。

是的。謝謝。我做到了。它的工作。 – Jay

我能夠到這個例子來編譯here。此時mvn clean package使用Maven 3.5.0。請注意，我還沒有嘗試運行該應用程序。

注意，我做了以下修改：

按照慣例，源代碼現在所在的模塊名稱匹配的文件夾中。

~/com.allstate.jigsaw/src/main/java/...

的module-info.java文件已被簡化了：

module com.allstate.jigsaw { 
    requires java.logging; 

    requires spring.boot; 
}

另外的，pom.xml已經更新，使用Java 9.是在根父pom.xml，另一個在模塊文件夾中。這裏是主要的依賴項，在com.allstate.jigsaw/pom.xml

<dependency> 
    <groupId>org.springframework.boot</groupId> 
    <artifactId>spring-boot-starter-web</artifactId> 
    <version>1.5.6.RELEASE</version> 
</dependency>

謝謝。感謝幫助。但是，運行這需要一些額外的工作。我必須在spring-boot-starter artifact中排除org.slf4j才能實現它。 – Jay
