Spring嵌入式Tomcat启动报错：Servlet.init()抛出NoSuchMethodException

Spring Web应用嵌入式Tomcat启动报错排查

我正在搭建第一个Spring Web应用，在main方法中配置了嵌入式Tomcat服务器，但启动时抛出CGLIB相关的NoSuchMethodException，推测是Spring配置问题但无法定位具体原因。项目完整代码已上传至代码仓库。

问题分析与解决方案

核心错误原因

报错指向PersistenceConfig类的CGLIB代理类缺少CGLIB$SET_THREAD_CALLBACKS方法，通常由以下情况导致：

  • 版本兼容性问题：Spring版本与Java版本不匹配，CGLIB在Java 9+模块化环境下需要特定Spring版本支持（如Spring 5.3+适配Java 8-17，Spring 6+要求Java 17+）。
  • 依赖冲突：项目中存在多版本的CGLIB或Spring核心依赖，导致类加载混乱，代理类生成失败。
  • 配置类限制：PersistenceConfig被声明为final类，或其中的方法被标记为final，导致CGLIB无法生成代理子类。

解决步骤

  1. 版本对齐：检查并确保Spring版本与当前Java版本兼容，调整pom.xml或build.gradle中的依赖版本。
  2. 清理依赖冲突：使用依赖分析工具（如mvn dependency:tree或gradle dependencies）排查重复依赖，排除冲突的CGLIB/Spring包，统一依赖版本。
  3. 修改配置类：移除PersistenceConfig类的final修饰符，确保配置方法也未被标记为final，允许CGLIB生成代理。
  4. 切换代理模式：若不想使用CGLIB，可在Spring配置中设置proxyTargetClass=false，强制使用JDK动态代理（需配置类实现对应接口）。
