java.lang.NoClassDefFoundError:启动Tomcat服务器时出现org / glassfish / jersey / jersey / internal / inject / Binder

tomcat

我正在使用Jersey和Maven在Java中构建REST API。我使用Tomcat 9作为服务器。一切正常,直到我今天尝试安装
RestAssured, HamcrestJUnit
。突然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.

这2个小时我做了什么:

  • 我试图找到此类:org/glassfish/jersey/internal/inject/Binder在Google上,但无济于事。
  • 我尝试卸载 RestAssuredHamcrestJUnit, 但没有帮助。

这个问题使我感到沮丧。知道为什么会发生此错误吗?提前致谢!

这是服务器日志的摘录:

核心JerseyJersey导入Binder该类的扩展库之一之间很可能存在版本不匹配的情况。确保所有与Jersey相关的模块都有明确的版本(并且彼此匹配)。甚至更好的是,通过导入jersey-
bom来修复您的版本。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<dependencies>部分可能会省略版本。
