java - 创建名称为 'org.springframework.validation.beanvalidation.OptionalValidatorFactoryBean#0 的 bean 时出错

Question

我是 hibernate 新手，不太确定我的应用程序出了什么问题。所以我有这两个模块:核心和网站。

• 模块核心具有所有实体、daos 和所有数据库工作。所有的 DAO 都继承了一个 AbstractDAO。
• 模块网站负责所有前端工作，例如 jsps、mvc Controller ...它是一个支持 spring 框架的 maven 模块。

我正在尝试使用 ehcache 工厂实现二级缓存。但是我收到了这个错误:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.validation.beanvalidation.OptionalValidatorFactoryBean#0': Invocation of init method failed; nested exception is java.lang.NoClassDefFoundError: Could not initialize class org.hibernate.validator.internal.engine.ConfigurationImpl org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean(AbstractAutowireCapableBeanFactory.java:1568) org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.doCreateBean(AbstractAutowireCapableBeanFactory.java:540) org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.createBean(AbstractAutowireCapableBeanFactory.java:476) org.springframework.beans.factory.support.AbstractBeanFactory$1.getObject(AbstractBeanFactory.java:302) org.springframework.beans.factory.support.DefaultSingletonBeanRegistry.getSingleton(DefaultSingletonBeanRegistry.java:229) org.springframework.beans.factory.support.AbstractBeanFactory.doGetBean(AbstractBeanFactory.java:298) org.springframework.beans.factory.support.AbstractBeanFactory.getBean(AbstractBeanFactory.java:193) org.springframework.beans.factory.support.DefaultListableBeanFactory.preInstantiateSingletons(DefaultListableBeanFactory.java:725) org.springframework.context.support.AbstractApplicationContext.finishBeanFactoryInitialization(AbstractApplicationContext.java:757) org.springframework.context.support.AbstractApplicationContext.refresh(AbstractApplicationContext.java:480) org.springframework.web.servlet.FrameworkServlet.configureAndRefreshWebApplicationContext(FrameworkServlet.java:663) org.springframework.web.servlet.FrameworkServlet.createWebApplicationContext(FrameworkServlet.java:629) org.springframework.web.servlet.FrameworkServlet.createWebApplicationContext(FrameworkServlet.java:677) org.springframework.web.servlet.FrameworkServlet.initWebApplicationContext(FrameworkServlet.java:548) org.springframework.web.servlet.FrameworkServlet.initServletBean(FrameworkServlet.java:489) org.springframework.web.servlet.HttpServletBean.init(HttpServletBean.java:136) javax.servlet.GenericServlet.init(GenericServlet.java:158) org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:502) org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:79) org.apache.catalina.valves.AbstractAccessLogValve.invoke(AbstractAccessLogValve.java:617) org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:518) org.apache.coyote.http11.AbstractHttp11Processor.process(AbstractHttp11Processor.java:1091) org.apache.coyote.AbstractProtocol$AbstractConnectionHandler.process(AbstractProtocol.java:668) org.apache.tomcat.util.net.AprEndpoint$SocketProcessor.doRun(AprEndpoint.java:2503) org.apache.tomcat.util.net.AprEndpoint$SocketProcessor.run(AprEndpoint.java:2492) java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) org.apache.tomcat.util.threads.TaskThread$WrappingRunnable.run(TaskThread.java:61) java.lang.Thread.run(Thread.java:745)

当我添加 logback-classic.jar 时出现错误，但如果我删除它，我会收到另一个错误。

org.springframework.web.util.NestedServletException: Handler processing failed; nested exception is java.lang.NoClassDefFoundError: ch/qos/logback/classic/selector/ContextSelector at org.springframework.web.servlet.DispatcherServlet.triggerAfterCompletionWithError(DispatcherServlet.java:1287) at org.springframework.web.servlet.DispatcherServlet.doDispatch(DispatcherServlet.java:961) at org.springframework.web.servlet.DispatcherServlet.doService(DispatcherServlet.java:877) at com.before90.website.action.application.ControllerServlet.doService(ControllerServlet.java:28) at org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:966) at org.springframework.web.servlet.FrameworkServlet.doGet(FrameworkServlet.java:857) at javax.servlet.http.HttpServlet.service(HttpServlet.java:622)

我不知道为什么会出现错误。它表明存在 spring 框架错误，其中 spring 未在模块核心(所有 DAO 所在的位置)中实现。任何建议将不胜感激。谢谢

如果你使用的是 hibernate-validator，在我的例子中，我只是添加了一个依赖如下:(因为在 JAVA 9 及更高版本中默认情况下 javax.xml.bind 在类路径上不可用，请引用 https://docs.oracle.com/javase/9/docs/api/java.xml.bind-summary.html)
