然后我切换到jdk 8并且工作正常。
Then I switched to jdk 8 and it working fine.
Spring-boot 2.0.0 RC2
当spring doc提到所需的Java时，为什么会发生这种情况版本为8或9。
Why this happening when spring doc mentioned the required Java version for it to be 8 or 9.
推荐答案
您需要添加JAXB依赖项（默认情况下在Java 9中不再提供）和您必须使用Spring Boot 2：
You need to add the JAXB dependency (as not provided any longer by default in Java 9) and you have to use Spring Boot 2 :
<dependency>
<groupId>javax.xml.bind</groupId>
<artifactId>jaxb-api</artifactId>
<version>2.3.0</version>
</dependency>
请注意，如果使用Java 10，则会遇到与JAXB依赖项删除完全相同的问题。不仅仅是针对Java 9版本。
Note that if you use Java 10, you would have exactly the same issue as the JAXB dependency removal was not done just for the Java 9 version.
关于Java 9及更高版本的Spring Boot wiki 列出了运行时需要知道的事项Java 9及更高版本的Spring Boot应用程序。
The Spring Boot wiki about Java 9 and above lists things that you need to know to run Spring Boot apps on Java 9 and above.
Spring Boot 1不支持它（并且没有计划）。< br>
Spring Boot 2支持它。
Spring Boot 1 doesn't support it (and no planned to).
Spring Boot 2 supports it.
Spring Boot 2是第一个支持Java 9的版本（Java 8也支持
）。如果您使用的是1.5并且希望使用Java 9，则应该将
升级到2.0，因为我们没有计划在Spring Boot上支持Java 9
1.5.x。
Spring Boot 2 is the first version to support Java 9 (Java 8 is also supported). If you are using 1.5 and wish to use Java 9 you should upgrade to 2.0 as we have no plans to support Java 9 on Spring Boot 1.5.x.
Java 10 从Spring Boot 2.0.1.RELEASE 开始受支持，而 Java 11 从Spring Boot 2.1.0.M2 开始支持。
Java 10 is supported as of Spring Boot 2.0.1.RELEASE while Java 11 is supported as of Spring Boot 2.1.0.M2.
AspectJ
使用Java 9，如果需要编写JDK中的类，则需要
使用AspectJ 1.9。在大多数情况下，使用
AspectJ 1.8（Spring Boot 2.0中的默认值），Spring AOP应该可以正常工作。
With Java 9, if you need to weave classes from the JDK, you need to use AspectJ 1.9. Spring AOP should work fine in most cases with AspectJ 1.8 (the default in Spring Boot 2.0).
JAXB
升级时，您可能面临以下情况：
When upgrading you may face the following:
java.lang.NoClassDefFoundError：javax / xml / bind / JAXBException
java.lang.NoClassDefFoundError: javax/xml/bind/JAXBException
Hibernate通常需要
默认不再提供的JAXB。您可以添加java.xml.bind模块以使用Java9或Java10恢复此
功能（即使该模块已弃用）。
Hibernate typically requires JAXB that’s no longer provided by default. You can add the java.xml.bind module to restore this functionality with Java9 or Java10 (even if the module is deprecated).
<dependency>
<groupId>javax.xml.bind</groupId>
<artifactId>jaxb-api</artifactId>
<version>2.3.0</version>
</dependency>
从Java11开始，该模块不可用，因此您唯一的选择是添加JAXB RI（您可以用Java9代替添加 java.xml.bind 模块：
As of Java11, the module is not available so your only option is to add the JAXB RI (you can do that as of Java9 in place of adding the java.xml.bind module:
<dependency>
<groupId>org.glassfish.jaxb</groupId>
<artifactId>jaxb-runtime</artifactId>
</dependency>
龙目岛
如果您使用的是lombok，则Spring Boot的托管版本可能无法与最新的JDK一起使用。请检查Lombok网站并在必要时覆盖其版本。
If you are using lombok, the managed version of Spring Boot may not work with the latest JDK. Check the Lombok web site and override its version if necessary.
这些库尚未完全支持Java 9：
These libraries do not have full support for Java 9 yet:
- Apache Cassandra，见＃10453
如果发生有关Java 9及更高版本兼容性的更改，请不要犹豫，编辑此帖子ty with Spring Boot。
Please, don't hesitate to edit this post if changes occur about the Java 9 and above compatibility with Spring Boot.
这篇关于切换到Java 9时，带有Spring Boot的javax.xml.bind.JAXBException的ClassNotFoundException的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
