Java 调试与Maven、Jersey、Tomcat、@ApplicationPath、no.xml不兼容的ClassChangeError

如果我尝试加载任何资源URL，会出现以下异常：

javax.servlet.ServletException: Servlet.init() for servlet com.example.project.Application threw exception
    org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:501)
    org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:103)

如何调试此回溯？

对于依赖项，您希望添加一个与其他版本兼容的servlet容器实现。也许：

<dependency>
    <groupId>org.glassfish.jersey.containers</groupId>
    <artifactId>jersey-container-servlet</artifactId>
    <version>${jersey.version}</version>
</dependency>

org.glassfish.jersey.containers
jersey容器servlet
${jersey.version}

删除：

<!-- needed for web.xml-less deploy -->
<dependency>
    <groupId>com.sun.jersey</groupId>
    <artifactId>jersey-servlet</artifactId>
    <version>1.18.1</version>
</dependency>

泽西岛
泽西servlet
1.18.1

吹走您的

目标

目录，然后重新运行

mvn包

，生成一个新的war文件

<!-- needed for web.xml-less deploy -->
<dependency>
    <groupId>com.sun.jersey</groupId>
    <artifactId>jersey-servlet</artifactId>
    <version>1.18.1</version>
</dependency>
