java - 我如何使用 JDK 1.7 运行 jersey 2.26？

Question

我的应用程序使用 JDK1.7。

我升级了 jersey 2.26，现在出现错误:

严重: Servlet [Jersey Web Application] in web application [/spcsis-1.0] threw load() exception

我已经将 jdk 更改为 1.8 然后它可以工作，但是我必须为我的项目使用 jdk1.7。

有人可以帮我做吗？

从 Jersey 2.26 开始，所有模块只支持 Java SE 8

参见 Jersey dependencies :

Until version 2.6, Jersey was compiled with Java SE 6. This has changed in Jersey 2.7.

Up to version 2.25.x almost all Jersey components are compiled with Java SE 7 target. It means, that you will need at least Java SE 7 to be able to compile and run your application that is using latest Jersey. Only core-common and core-client modules are still compiled with Java class version runnable with Java SE 6.

Since Jersey 2.26, all modules are build using Java SE 8 and there is no support for running it on older Java SE distributions.
