2 个答案:

答案 0 :(得分：1)

您需要：

1）更改您的依赖项列表以仅引用JDK 1.7兼容库

2）使用JDK 1.8

安装并运行您的应用程序

问题，正如消息中所解释的那样，ClassLoader无法加载类javax.inject.Provider，javax.enterprise.inject.Instance和/或javax.enterprise.inject.spi.CDI，因为它们是用Java 1.8编译的。您可以尝试查找相应jar的旧版本，但这可能会导致与您的实际代码不兼容。我建议你将生产JDK升级到最新的1.8分支。

顺便说一句，JDK 1.7已经过期，不应该再使用了：http://www.oracle.com/technetwork/java/eol-135779.html#Java6-end-public-updates

答案 1 :(得分：0)

您需要在1.8版本的Java上运行和编译您的应用程序。

对于Eclipse，你应该这样做：

1）点击“Window＆gt; Preferences”，在出现的窗口左侧的“Java”下，点击“Installed JREs”，点击“Add ...”导航到包含JDK。

2）右键单击项目并单击“属性”，在左侧窗口中，单击“Java编译器”并取消选中“在Java构建路径上使用执行环境中的合规性”，这样您就可以选择list“Compiler compilance level”使用您在上一步中设置的相同版本。

对于NetBeans IDE，右键单击项目并选择“属性”然后转到源，然后可以将“源/二进制格式”更改为较高的enter image description here JDK版本。
