mysql是由：java引起的。lang.NoClassDefFoundError:无法初始化类javassist。util。代理DefineClassHelper
我正在和一个团队一起做一个uni项目。当我在前端工作时，团队的一部分与后端的数据库建立了连接。但当我试图使用来自api的get请求时，我的glass fish日志中出现了错误。我有时在跑步时会犯不同的错误。 我们正在使用持久性构建一个web应用程序。 当我在浏览器中使用正确的url时，会出现以下错误：
SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data
以及：
javax.persistence.PersistenceException: [PersistenceUnit: VodafoneZiggoDB] Unable to build Hibernate SessionFactory
奇怪的是，我的队友没有这个问题。我们有相同的想法和mysql工作台版本。我们有不同的mysql服务器版本。因为我在macOS上工作，而他们没有
我尝试过添加javassist。罐子到pom，清洁和安装，但这不起作用。 我尝试重新安装IntelliJ，但没有成功。 我尝试在pom中使用不同的mysql连接器版本。 我试图找到解决stackoverflow问题的方法，但没有成功

预期结果是不会在浏览器或玻璃鱼日志中获取这些错误。并在后端和mysql工作台之间建立连接
