警告：上下文初始化期间遇到异常 \- 取消刷新尝试

错误如下图所示。问题是，发生如下，这个 XmlWebApplicationContext 不需要发生，因为它再次注入 bean。如何避免？

然后我们在文件夹“CONTEXT”中有一堆可用的上下文 xml。

这是我的愚蠢，但不容易识别的愚蠢:)。

问题：

我的代码是在 Jdk 1.8 上编译的。
我的 Eclipse 使用 JDK 1.8 作为编译器。
我在 Eclipse 中的 tomcat 使用 Java 1.7 作为其容器，因此它无法理解使用 1.8 编译的 .class 文件。
为避免此问题，请确保在您的 Eclipse 中，双击您的服务器 -> 打开启动配置 -> 类路径 -> JRE 系统库 -> 提供 java 类的编译版本的 JDK/JRE，在我的情况下，它必须是 JDK 1.8
1. 发布这个，清理服务器，构建和重新部署，启动 tomcat。

如果您要手动部署到服务器中，请确保您的 JAVA_HOME、JDK_HOME 指向您用于编译项目和构建战争的正确 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！
