java.lang.NoClassDefFoundError: org/glassfish/jersey/internal/inject/Binder when started Tomcat Server

2022-09-02 21:06:19

我正在用Java与Jersey和Maven一起构建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、HamcrestJUnit。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.

我做了什么2个小时:

  • 我试图找到这个类:在谷歌上,但无济于事。org/glassfish/jersey/internal/inject/Binder
  • 我试图卸载RestAssuredHamcrestJUnit,但它没有帮助。

这个问题让我感到沮丧。任何想法为什么会发生这个错误?提前致谢!

以下是服务器日志的摘录:

核心与导入该类的扩展库之一之间很可能存在版本不匹配。确保所有与泽西岛相关的模块都有明确的版本(并且它们彼此匹配)。或者更好的是,通过导入球衣bom来修复您的版本。例如:JerseyJerseyBinder

<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,您的主要部分可能会省略版本。<dependencies>


答案 2

我在使用不同版本时遇到了同样的问题。确保您的 Jersey-bean-validation 和 Jersey-container-servlet 版本相同。

<dependency>
    <groupId>org.glassfish.jersey.containers</groupId>
    <artifactId>jersey-container-servlet</artifactId>
    <version>2.22</version>
</dependency>
<!-- bean validation -->
<dependency>
    <groupId>org.glassfish.jersey.ext</groupId>
    <artifactId>jersey-bean-validation</artifactId>
    <version>2.22</version>
</dependency>
