【问题描述】：

我正在使用 ehcache 测试 Spring Boot 1.3.0.M3 并遇到了一些问题。

当我启动应用程序时，控制台上出现以下异常：

线程“main”中的异常 org.springframework.beans.factory.BeanCreationException：错误 创建在类路径中定义的名称为“velocityConfigurer”的bean 资源 [org/springframework/boot/autoconfigure/velocity/VelocityAutoConfiguration$VelocityWebConfiguration.class]： 调用 init 方法失败；嵌套异常是 java.lang.NoClassDefFoundError： org/apache/velocity/runtime/log/CommonsLogLogChute 在 org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean(AbstractAutowireCapableBeanFactory.java:1578) 在 org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.doCreateBean(AbstractAutowireCapableBeanFactory.java:545) 在 org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.createBean(AbstractAutowireCapableBeanFactory.java:482) 在 org.springframework.beans.factory.support.AbstractBeanFactory$1.getObject(AbstractBeanFactory.java:305) 在 org.springframework.beans.factory.support.DefaultSingletonBeanRegistry.getSingleton(DefaultSingletonBeanRegistry.java:230) 在 org.springframework.beans.factory.support.AbstractBeanFactory.doGetBean(AbstractBeanFactory.java:301) 在 org.springframework.beans.factory.support.AbstractBeanFactory.getBean(AbstractBeanFactory.java:196) 在 org.springframework.beans.factory.support.DefaultListableBeanFactory.preInstantiateSingletons(DefaultListableBeanFactory.java:772) 在 org.springframework.context.support.AbstractApplicationContext.finishBeanFactoryInitialization(AbstractApplicationContext.java:834) 在 org.springframework.context.support.AbstractApplicationContext.refresh(AbstractApplicationContext.java:537) 在 org.springframework.boot.context.embedded.EmbeddedWebApplicationContext.refresh(EmbeddedWebApplicationContext.java:118) 在 org.springframework.boot.SpringApplication.refresh(SpringApplication.java:667) 在 org.springframework.boot.SpringApplication.doRun(SpringApplication.java:342) 在 org.springframework.boot.SpringApplication.run(SpringApplication.java:273) 在 org.springframework.boot.SpringApplication.run(SpringApplication.java:971) 在 org.springframework.boot.SpringApplication.run(SpringApplication.java:960) 在 com.aconso.creator2.CreatorApplication.main(CreatorApplication.java:26) 引起：java.lang.NoClassDefFoundError： org/apache/velocity/runtime/log/CommonsLogLogChute 在 org.springframework.ui.velocity.VelocityEngineFactory.createVelocityEngine(VelocityEngineFactory.java:238) 在 org.springframework.web.servlet.view.velocity.VelocityConfigurer.afterPropertiesSet(VelocityConfigurer.java:120) 在 org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.invokeInitMethods(AbstractAutowireCapableBeanFactory.java:1637) 在 org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean(AbstractAutowireCapableBeanFactory.java:1574) ... 16 更多原因：java.lang.ClassNotFoundException： org.apache.velocity.runtime.log.CommonsLogLogChute 在 java.net.URLClassLoader$1.run(URLClassLoader.java:366) 在 java.net.URLClassLoader$1.run(URLClassLoader.java:355) 在 java.security.AccessController.doPrivileged(Native Method) 在 java.net.URLClassLoader.findClass(URLClassLoader.java:354) 在 java.lang.ClassLoader.loadClass(ClassLoader.java:425) 在 sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:308) 在 java.lang.ClassLoader.loadClass(ClassLoader.java:358) ... 20 更多

我的类路径中有一个 ehcache.xml，并且实例化了 EHCacheManager。 当我删除 spring-boot-starter-cache- 和 ehcache-dependency 时，一切都开始正常。 （但只能使用 ConcurrentMapCacheManager）

问题：

我是否需要 spring-boot-starter-cache 的速度或是否有其他缺失或错误？

【问题讨论】：

看来 CommonsLogLogChute 不在你的 classPath 中。 :"嵌套异常是 java.lang.NoClassDefFoundError: org/apache/velocity/runtime/log/CommonsLogLogChute"

【参考方案1】：

我对 spring-security-cas 有同样的问题，具体取决于速度。您可以通过添加来解决问题

@EnableAutoConfiguration(exclude = VelocityAutoConfiguration.class)

到你的 Spring Boot 应用程序主类

【参考方案2】：

VelocityAutoConfiguration 仅在类路径中存在这两个类时才会生效：

@ConditionalOnClass( VelocityEngine.class, VelocityEngineFactory.class )

它们分别来自org.apache.velocity:velocity 和org.springframework:spring-context-support。

您可以通过以下方式确定哪些依赖项将这些依赖项传递到项目中：

mvn dependency:tree

【讨论】：

使用 spring-starter-cache 和 ehcache 需要速度吗？当需要它时，为什么 spring-data-cache 没有它作为依赖项？我使用 thymeleaf 作为模板引擎，也不需要速度。

好的，org.springframework:spring-context-support 在我的依赖项中。它来自 org.springframework.boot:spring-boot-starter-cache。但我在我的依赖树中没有找到 org.apache.velocity:velocity。

也许名字稍有不同，试试mvn dependency:tree | grep velocity

嗯，好的。我编辑了我的帖子并添加了依赖项：树。似乎 spring-security-cas 依赖于velocity:velocity:jar。我现在的解决方案是添加 spring-boot-starter-velocity 依赖项并通过 spring.velocity.enabled=false 在 application.properties 中禁用它。之后它似乎工作正常。

【参考方案3】：

使用最新版本的 Spring Boot，你可以做到这一点 -

@SpringBootApplication(exclude = VelocityAutoConfiguration.class)
