推荐选项
- 不支持 major.minor 版本 52.0 意味着您的 Web/Application 服务器存在 JDK 版本兼容性问题。
- 将其更改为更高 JDK 最好 JDK 1.8（推荐）并重新编译您的代码将解决您的问题。
- 在这种情况下，强烈建议使用 tomcat 8.X + JDK 1.8 来解决您的问题。

推荐选项
- 不支持 major.minor 版本 52.0 意味着您的 Web/Application 服务器存在 JDK 版本兼容性问题。
- 将其更改为更高 JDK 最好 JDK 1.8（推荐）并重新编译您的代码将解决您的问题。
- 在这种情况下，强烈建议使用 tomcat 8.X + JDK 1.8 来解决您的问题。
