如何为Java 11 + JavaFX Hibernate模块修复module-info.java

时间：2019-08-29 02:21:00

标签： java maven jpa javafx modularity

我正在使用Java11创建一个简单的测试应用程序，以学习JPA，Hibernate，一些Java模块化以及以后的功能（带有Dagger的CDI），并且当我使用module-info.java时遇到编译问题

我为一些DAO repositories做了一些simple classes，这些工作都被JPA注释以对其进行测试，并且一切顺利地在我Main class上成功完成，其中我成功插入和检索了一些对象。 注意：到目前为止，我还没有module-info.java

现在，我正在制作一些FXML（使用scenebuilder）。我之前已经做过，而且我必须创建一个module-info.java来解决一些JavaFX问题（我认为这与Java反射有关）：我在其他project中做到了这一点，并且按预期工作。这是由Intellij警告解决的，这些警告是通过IntelliJ解决它们或某些运行时异常而解决的，通知我app.a软件包需要打开到app.b软件包，然后我手动进行操作。这是我第一次使用module-info.java

因此，当我尝试通过另一类MainFX使用gui时，会遇到一些错误（我将尝试解决，但不是这个问题的意思）：

Caused by: java.lang.IllegalAccessError: class com.sun.javafx.fxml.FXMLLoaderHelper (in unnamed module @0x71b9e075) cannot access class com.sun.javafx.util.Utils (in module javafx.graphics) because module javafx.graphics does not export com.sun.javafx.util to unnamed module @0x71b9e075
    at com.sun.javafx.fxml.FXMLLoaderHelper.<clinit>(FXMLLoaderHelper.java:38)
    at javafx.fxml.FXMLLoader.<clinit>(FXMLLoader.java:2056)
    at app.control.MainControl.loadFXML(MainControl.java:22)
    at app.MainFX.start(MainFX.java:42)


正是在这一点上，我试图添加一个module-info.java并解决了IntelliJ捕获的所有导入依赖关系，并添加了一些我的模块依赖关系：


module bartest {
    requires com.google.common;
    requires javafx.controls;
    requires javafx.graphics;
    requires javafx.fxml;
    requires flogger;
    requires java.logging;
    requires java.persistence;


    opens app;

}


但是我尝试过的任何事情都会得到java.lang.module.ResolutionException

当我删除module-info.java时，我开始获得成功的构建，并且非javaFX代码也可以正常工作。我想如果没有module-info.java，module-info会自动正确生成。

所以我的module-info.java无法编译，没有编译，但是我不能运行JavaFX，而如果没有module-info.java文件，它可能可以解决，但是我想知道是什么原因造成的如您所知，我对大多数概念（Maven，JPA，模块化）还算陌生，我的测试目标是学习，所有帮助将不胜感激。

我认为可能会影响的其他原因是我缺乏使用maven pom.xml文件的经验，我基本上是让Intellij生成我在互联网上搜索的依赖项和插件标签，但可能是错误的

编辑1：
HERE用户Gili指出：

  

“ Eclipse基金会有taken over JavaEE development。javax.activation已按wiki.eclipse.org/New_Maven_Coordinates移至jakarta.activation”

所以我尝试将以下部门添加到pom中

    <dependency>
      <groupId>jakarta.activation</groupId>
      <artifactId>jakarta.activation-api</artifactId>
      <version>1.2.1</version>
    </dependency>
    <dependency>
      <groupId>jakarta.persistence</groupId>
      <artifactId>jakarta.persistence-api</artifactId>
      <version>2.2.2</version>
    </dependency>
    <dependency>
      <groupId>jakarta.transaction</groupId>
      <artifactId>jakarta.transaction-api</artifactId>
      <version>1.3.1</version>
    </dependency>

在构建时仍然失败，并且我在module-info文件上收到警告

Error:java: java.lang.module.ResolutionException: Modules java.activation and jakarta.activation export package javax.activation to module error.prone.annotations
Information:java: java.lang.module.ResolutionException: Modules jakarta.activation and java.activation export package javax.activation to module javafx.webEmpty
Information:java: Errors occurred while compiling module 'bartest'

Information:29/08/2019 4:03 a. m. - Build completed with 1 error and 0 warnings in 4 s 405 ms

编辑2： 我确实遵循过IntelliJ can't recognize JavaFX 11 with OpenJDK 11 之前导致我进入running JavaFX projects的情况，但是当我按照那里的说明添加module-info.java时，我得到了上面粘贴的异常。在建立。显然，模块jakarta.activation和java.activation都存在导出包javax.activation的问题，但是我不知道如何解决这个问题

1 个答案:

答案 0 :(得分：2)

此补丁程序已经引起了我的注意...出于文档原因在这里无法解释

我添加了https://stackoverflow.com/a/48136912/11970095之后

    <dependency>
      <groupId>org.glassfish.jaxb</groupId>
      <artifactId>jaxb-runtime</artifactId>
      <version>2.3.2</version>
    </dependency>

消除此问题解决了一个大问题，唯一缺少的是module-info.java，它在修复了必需的模块后现在看起来像这样

module bartest {
    requires com.google.common;
    requires javafx.controls;
    requires javafx.graphics;
    requires javafx.fxml;
    requires flogger;
    requires java.logging;
    requires net.bytebuddy;
    requires java.sql;
    requires java.xml.bind;

    opens app.control to javafx.fxml;
    opens app.model to org.hibernate.orm.core;

    opens app;

}

现在一切正常。
