java.lang.NoClassDefFoundError:org/glassfish/jersey/internal/inject/Binder启动Tomcat Server时

Question

我正在使用Jersey和Maven在Java中构建REST API.我使用Tomcat 9作为我的服务器.一切正常,直到我今天尝试安装RestAssured, Hamcrest和JUnit.突然间,我的所有端点都抛出了500个内部服务器错误.500错误的根本原因是java.lang.NoClassDefFoundError: org/glassfish/jersey/internal/inject/Binder.

我这2小时做了什么:

• 我试图找到这个类:org/glassfish/jersey/internal/inject/Binder在谷歌上,但没有用.
• 我试图卸载RestAssured,Hamcrest和JUnit,但它没有帮助.

这个问题让我感到沮丧.知道为什么会发生这种错误吗？提前致谢!

以下是服务器日志的摘录:

很可能核心Jersey和导入Binder类的Jersey扩展库之间存在版本不匹配.确保所有与Jersey相关的模块都有明确的版本(并且它们相互匹配).或者甚至更好,通过导入jersey-bom修复您的版本.例如:

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.glassfish.jersey</groupId>
            <artifactId>jersey-bom</artifactId>
            <version>2.26-b03</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>

之后您的主要Jersey部分可能会省略版本.
