    答案

    这个错误发生的原因可能是 jackson-databind 库没有被正确地加载或者类路径（classpath）中存在冲突。尽管 Maven 在调试输出中显示已经添加了 jackson-databind 到类路径中，但仍然出现了 javassist.NotFoundException，这通常表示在运行时无法找到指定的类。

    可能的解决方案包括：

    1. 检查 jackson-databind 的版本：
      确保项目中使用的 jackson-databind 版本与代码中引用的版本一致。有时候，如果项目中包含了多个版本的同一个库，可能会导致类加载问题。
    2. 检查项目的依赖树：
      使用 mvn dependency:tree 命令来查看项目的依赖树，检查是否有其他依赖间接引入了不同版本的 jackson-databind。
    3. 清理和重新构建项目：
      有时候，简单的清理和重新构建项目可以解决类路径问题。可以尝试运行 mvn clean install。
    4. 检查 Maven 配置：
      确保 pom.xml 文件中的配置正确无误，特别是关于依赖和插件的部分。
    5. 确保没有类加载器问题：
      如果你的应用使用了复杂的类加载器机制（例如在 Web 容器中运行），确保 jackson-databind 类可以被正确加载。
    6. 使用 -e 和 -X 选项重新运行 Maven：
      使用更详细的输出选项来重新运行 Maven，可能会提供更多关于问题的线索。
    mvn exec:java -Dexec.classpathScope=compile -Dexec.mainClass="com.xiinnn.commonly.POJOJackson" -e -X

    通过这些步骤，你应该能够诊断并解决这个问题。如果问题仍然存在，可能需要更深入地检查代码和配置。

      1. 在你的 pom.xml 文件中添加或更新上述依赖项
      2. 开发过程使用mvn clean compile验证编译是否通过
      3. 如果第二步验证正通过准备发布或需要完整构建时：使用 mvn clean install

      4. 然后再次运行你的命令：

        mvn exec:java -Dexec.classpathScope=compile -Dexec.mainClass="com.xiinnn.commonly.POJOJackson"

      补充

      使用 LoaderClassPath 方法，确保 javassist 使用当前线程的类加载器来查找类路径，这样可以更好地处理依赖关系。以下是具体的代码示例：

      ClassPool classPool = ClassPool.getDefault();
classPool.appendClassPath(new LoaderClassPath(Thread.currentThread().getContextClassLoader()));
CtClass ctClass = classPool.get("com.fasterxml.jackson.databind.node.BaseJsonNode");

      可以将这段代码添加到你项目的主类或需要使用 javassist 的类中。假设你有一个主类 Main，你可以在 main 方法中添加这段代码。
