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

java.lang.NoClassDefFoundError: org/glassfish/jersey/internal/inject/Binder when started Tomcat Server(java.lang.NoClassDefFoundError: org/glassfish/jersey/internal/inject/Binder 启动 Tomcat 服务器时)

问题描述

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.在我今天尝试安装 RestAssured、 Hamcrest、 和 JUnit 之前，一切正常.突然间，我所有的端点都抛出了 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.

I am building REST API in Java with Jersey and Maven. I used Tomcat 9 as my server. Everything works fine until I tried to install RestAssured, Hamcrest, and JUnit today. Suddenly all of my endpoints threw out 500 Internal server errors. The root cause of the 500 error is java.lang.NoClassDefFoundError: org/glassfish/jersey/internal/inject/Binder.

这两个小时我做了什么:

What I have done this 2 hours:

• 我曾尝试在 google 上找到此类:org/glassfish/jersey/internal/inject/Binder，但无济于事.
• 我曾尝试卸载 RestAssured、Hamcrest 和 JUnit，但没有帮助.

• I have tried to find this class: org/glassfish/jersey/internal/inject/Binder on google, but no avail.
• I have tried to uninstall RestAssured, Hamcrest, and JUnit but it didn't help.

这个问题让我很沮丧.知道为什么会发生此错误吗?提前致谢！

This problem makes me frustrated. Any idea why this errors happened? Thanks in advance!

推荐答案

核心 Jersey 与导入的 Jersey 扩展库之一之间很可能存在版本不匹配Binder 类.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).或者更好的是，通过导入 jersey-bom 来修复您的版本.例如:

Very likely there is a version mismatch between core Jersey and one of the Jersey extension libraries that imports that Binder class. Make sure all Jersey-related modules have explicit versions (and they match each other). Or even better, fix your versions by importing the jersey-bom. E.g.:

<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.

After which your main <dependencies> section may omit the versions.
