我在使用maven为我的程序创建可执行战争时遇到了麻烦。
当前的问题是，当我在Eclipse中运行程序时，一切正常，但是一旦构建.war它就不起作用 - 它会抛出NoClassDefFoundError：/ org / Hibernate / SessionFactory。
因为这是main方法调用的第一个类，我怀疑它不是hibernate的问题，而是war的classpath，但我不明白为什么。这是我的pom.xml：

所有依赖项也位于Eclipse中的构建类路径中。 我试图用命令java -jar pipe-1.0.war来运行它。
感谢任何帮助

如果您反编译jar并检查Manifest文件，您可能会看到使用main方法的类未正确声明。
因此，您可以尝试将此插件添加到您的pom xml文件中：
<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<configuration>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
<archive>
<manifest>
<addClasspath>true</addClasspath>
<mainClass>yourpackage.Mainclass</mainClass>
</manifest>
</archive>
</configuration>
</plugin>

Hibernate 5.2及更高版本至少需要Java 1.8，而你使用的是1.7：
<configuration>
<source>1.7</source>
<target>1.7</target>
<encoding>UTF-8</encoding>
<showWarnings>true</showWarnings>
<showDeprecation>true</showDeprecation>
</configuration>
