Spring 5被提升为支持JDK 9，同时Spring 4.3.13的文档声明它支持 。
Spring 5 is promoted as "with support for JDK 9", meanwhile the documentation for Spring 4.3.13 states that it supports Java 8 (as well as 6 and 7).
这是否意味着我需要升级到Spring 5才能
Does this mean that I need to upgrade to Spring 5 before I can
- 在JRE 9中运行我的应用程序？
- 使用JDK 9编译我的应用程序？
推荐答案
Spring
On ，他们宣布Spring 4.2将支持Java 7和8（它在4.3中没有变化），他们也表示Spring 5将支持Java 9。
Spring
On the official Spring blog, they announced that Spring 4.2 would support Java 7 and 8 (it didn't change in 4.3), and they also said that Spring 5 would support Java 9.
暗示Spring 4不支持Java 9。
It is implied that Spring 4 won't support Java 9.
但这取决于你哟你正在做：在上，作者在Spring 4上测试Java9他说：
But it depends of what you're doing: on this blog, the writer is testing Java9 on Spring 4 and he said:
因为不支持只意味着你不确定如果您使用的是Java9中的任何更改，您应该考虑迁移（除非您可以先测试）。
Because "doesn't support" only means you're not sure of the comportment, If you're using anything that changed in Java9, you should consider migrating (unless you can test it first).
Spring boot 1.x 不支持 Java9。如果您想使用它，必须迁移到Spring Boot 2.x.
Spring boot 1.x does not support Java9. If you want to use it, you have to migrate to Spring Boot 2.x.
