解决方案

只需将合适版本的 cglib 放在类路径中。

<dependency>
	<groupId>cglib</groupId>
	<artifactId>cglib</artifactId>
	<version>2.2.2</version>
</dependency>
<dependency>
	<groupId>asm</groupId>
	<artifactId>asm-util</artifactId>
	<version>3.3.1</version>
</dependency>

原因

此错误是由于 cglib 的版本与项目中的其他 jar 文件不兼容

java使用cglib时报错：
