Java 17 无法调用“java.lang.reflect.Method.invoke(Object, Object[])”，因为 com.sun.xml.bind.v2.runtime.reflect.opt.Injector.defineClass 为 null

Question

我在 spring boot 中有一个带有 oauth2 的小项目，我想运行资源服务器

设置：

• 爪哇17
• spring-boot-starter-parent 版本 2.5.6
• spring-cloud-dependency 版本 2020.0.4
• spring-boot-starter-oauth2-资源服务器
• spring-security-oauth2-自动配置

当我想运行我的应用程序时，我有例外：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'springSecurityFilterChain' defined in class path resource [org/springframework/security/config/annotation/web/configuration/WebSecurityConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [javax.servlet.Filter]: Factory method 'springSecurityFilterChain' threw exception; nested exception is java.lang.NullPointerException: Cannot invoke "java.lang.reflect.Method.invoke(Object, Object[])" because "com.sun.xml.bind.v2.runtime.reflect.opt.Injector.defineClass" is null

您知道可能出了什么问题吗？

Answer 1

考虑在依赖项中添加 xml lib，如下所示：

<dependency>
        <groupId>com.sun.xml.bind</groupId>
        <artifactId>jaxb-impl</artifactId>
        <version>2.3.1</version>
    </dependency>
    <dependency>
        <groupId>com.sun.xml.messaging.saaj</groupId>
        <artifactId>saaj-impl</artifactId>
        <version>1.5.1</version>
    </dependency>

Answer 2

只需添加此依赖项，错误就消失了：

<dependency>
    <groupId>com.sun.xml.bind</groupId>
    <artifactId>jaxb-impl</artifactId>
    <version>3.0.2</version>
</dependency>

感谢@用户

这是用以下方法测试的：

• JDK 17（Eclipse Temurin）
• 春季启动2.6.2
• 春云2021.0.0
• org.springframework.security.oauth.boot:spring-security-oauth2-自动配置

Answer 3

升级maven-jaxb2-plugin 到该版本0.15.1解决了我的问题。

 <plugin>
      <groupId>org.jvnet.jaxb2.maven2</groupId>
      <artifactId>maven-jaxb2-plugin</artifactId>
      <version>0.15.1</version>
 </plugin>
