在 Tomcat 8 上启动 Spring 应用程序时出现 java.lang.IllegalAccessError

Question

当我尝试在 Tomcat 8 上运行该项目时，出现了这个非常奇怪的错误:

INFO o.s.web.context.ContextLoader - Root WebApplicationContext: initialization started . INFO o.s.w.c.s.AnnotationConfigWebApplicationContext - Refreshing Root WebApplicationContext: startup date [Mon Jun 29 10:59:34 CEST 2015]; root of context hierarchy . INFO o.s.w.c.s.AnnotationConfigWebApplicationContext - Registering annotated classes: [class com...]

ERROR o.s.web.context.ContextLoader - Context initialization failed java.lang.IllegalAccessError: tried to access method org.springframework.beans.factory.support.DefaultSingletonBeanRegistry.getSingletonMutex()Ljava/lang/Object; from class org.springframework.context.event.AbstractApplicationEventMulticaster

我的第一个想法是 Spring 版本中有一些错误，但我找不到任何东西。这与我使用过几次的项目设置几乎相同，唯一的区别是这是 Java 8 项目。

项目是 Dynamic Web Module 3.1。

下面是 .pom 文件的依赖项，我没有看到版本中有任何冲突。

如果有人以前遇到过这个问题，请提供帮助。

Answer 1

问题是您正在混合不兼容的不同版本的 Spring。无论如何，您永远不应该混合来自任何框架(Spring、Hibernate、JSF 等)的不同版本的 jar，因为那一定会发生麻烦。

最好的方法是简单地使用 Spring IO Platform .

将以下内容添加到您的 pom

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>io.spring.platform</groupId>
            <artifactId>platform-bom</artifactId>
            <version>1.1.2.RELEASE</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>

然后删除您的 pom 中的版本，因为这些版本现在由 platform-b​​om 管理，您现在应该拥有可以协同工作的版本并且不再有冲突的版本。如需托管版本列表，请查看此 appendix .
