RESTEasy Java 11、Tomcat 10.1 如何部署运行

问题描述 投票：0回答：1

从那时起，我就在谷歌上搜索有关如何部署和运行 RESTEasy JAX-RS 测试应用程序的工作解决方案。 它必须至少在 Java 11 和 Tomcat 10.1 上运行，使用最实际的 JAX-RS 和 RESTEasy 版本。

无论我尝试如何启动并运行它，每个 URL 调用 - 例如 - http://localhost:8080/NetworkManagement/network-management/configurations 以错误 404 结束。

请问有人可以给我一个提示或解决方案吗？

自上次实际尝试使用的代码片段将发布在下一篇文章中 - Eclipse 22.06 maven 项目：

您的 RESTEasy 依赖项看起来不正确。您混合了两个不同版本的 RESTEasy，这是行不通的。如果您使用 Tomcat 10 使用的 Jakarta EE 9+，则需要使用 6.2.2.Final。您的依赖项应该看起来更像：

<dependency>
    <groupId>org.jboss.resteasy</groupId>
    <artifactId>resteasy-client</artifactId>
    <version>${resteasy-version}</version>
</dependency>

<dependency>
    <groupId>org.jboss.resteasy</groupId>
    <artifactId>resteasy-core</artifactId>
    <version>${resteasy-version}</version>
</dependency>

<dependency>
    <groupId>org.jboss.resteasy</groupId>
    <artifactId>resteasy-jaxb-provider</artifactId>
    <version>${resteasy-version}</version>
</dependency>

<dependency>
    <groupId>org.jboss.resteasy</groupId>
    <artifactId>resteasy-servlet-initializer</artifactId>
    <version>${resteasy-version}</version>
</dependency>
