Java 警告：上下文初始化期间遇到异常-取消刷新尝试

错误如下所示。问题是，如下所示，这个XmlWebApplicationContext不需要出现，因为它再次注入bean。如何避免呢

重要的是：

Cannot find class [com.rakuten.points.persistence.manager.MemberPointSummaryDAOImpl] for bean with name 'MemberPointSummaryDAOImpl' defined in ServletContext resource [/WEB-INF/context/PersistenceManagerContext.xml];

由于：

nested exception is java.lang.ClassNotFoundException: com.rakuten.points.persistence.manager.MemberPointSummaryDAOImpl

---

根据此日志，Spring找不到您的

MemberPointSummaryDAOImpl

类。

这是我的愚蠢，但不容易识别：）

问题:

我的代码是在JDK1.8上编译的

我的eclipse使用JDK1.8作为编译器

eclipse中的tomcat使用Java1.7作为其容器，因此它无法理解使用1.8编译的.class文件

为了避免这个问题，请确保在eclipse中双击服务器->打开启动配置->类路径->JRE系统库->提供java类编译版本的JDK/JRE，在我的例子中，它必须是JDK 1.8

发布此消息，清理服务器，构建并重新部署，启动tomcat

如果要手动部署到服务器中，请确保JAVA_HOME、JDK_HOME指向用于编译项目和构建war的正确JDK

---

如果您不喜欢更改JAVA_HOME、JDK_HOME，您可以随时更改catalina.bat（用于tomcat服务器）中的JAVA_HOME和JDK_HOME，这将使您的生活变得轻松

在我的例子中，我使用的是j-hipster，我必须做

/mvnw clean

来克服这个警告。

作为一个初学者，我遇到了这个问题

我保存的xml文件路径有问题

对于封闭的思想

要删除所有文件夹和文件C:/Users/UserName/.m2/org/*

打开想法并更新Maven项目（右键单击project->Maven->update Maven project）

之后，更新项目

嘿，我知道会出现错误，但这不是问题所在！在我的pom里。我会更新pom和截图，让大家来上课。这不是问题所在。问题在于：警告：在上下文初始化过程中遇到异常-取消刷新尝试您可以验证这个jar（其中包含这个类）在Tomcat工作目录中的WEB-INF/lib文件夹下是否可用吗？这个jar确实存在于lib文件夹中的这个类中。由于某种原因，我无法上传截图。当然，它确实存在。我看到的问题是，它无法取消刷新，因此bean再次被注入，并在那里抛出一个错误。@Pavanraotk:我面临着同样的问题。你找到解决方案了吗？@RockingDev:检查我上面的答案，我的答案是因为我eclipse中的tomcat在JDK 1.7上，所以出现了问题。它会和你一样吗？
