执行maven .war时使用NoClassDefFoundError: /org/Hibernate/SessionFactory

Question

我在使用maven为我的程序创建可执行的war时遇到了问题。

当前的问题是，当我在Eclipse中运行程序时，一切都运行得很好，但是一旦构建了.war，它就不能工作了-它抛出了一个NoClassDefFoundError: /org/Hibernate/SessionFactory。

因为这是main方法调用的第一个类，所以我怀疑这不是hibernate的问题，而是war的类路径的问题，但我不明白为什么。这是我的pom.xml：

所有依赖项也都在Eclipse的构建类路径中。顺便说一下，我正在尝试使用命令java -jar pipe-1.0.war来运行它。

任何帮助我们都将不胜感激

Answer 1

如果反编译jar并检查Manifest文件，您可能会看到带有main方法的类没有正确声明。

因此，您可以尝试将此插件添加到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>

Answer 2

Hibernate 5.2和更高版本至少需要Java 1.8，而您在以下位置使用1.7：

<configuration>
    <source>1.7</source>
    <target>1.7</target>
    <encoding>UTF-8</encoding>
    <showWarnings>true</showWarnings>
    <showDeprecation>true</showDeprecation>
</configuration>
