我正在与一个团队一起进行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联系。但是，当我尝试使用来自api的get请求时，我的玻璃鱼日志中出现了错误。我有时会在跑步时遇到不同的错误。 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网址时，会出现以下错误：
SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data
和：
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IDEA和mysql工作台版本。我们确实有不同的mysql服务器版本。当我在macOS上工作时，他们不会。
我尝试将javassist.jar添加到pom中，并进行清洁和安装，但这没有用。 我试过重新安装IntelliJ，但是没有运气。 我试过在pom中使用不同的mysql连接器版本。 我尝试过在stackoverflow上找到没有成功的解决方案。

当我在mysql连接器版本之间切换时，我还会收到Driver＃Connect错误。
预期结果未在浏览器或玻璃鱼日志中得到这些错误。并实际上在后端和mysql工作台之间建立了连接。
答案 0 :(得分：0)
我已经重新导入了Maven依赖项，mvn clean install verify compile打包了。然后，我重新安装了payara 5并编辑了配置。 现在它就像一种魅力！
