maven - 运行未修改的原型(prototype) CXF JAX RS 项目时出错

Question

我正在尝试运行原型(prototype)生成的项目: org.apache.cxf.archetype:cxf-jaxrs-服务

我使用 Maven 生成它并尝试在 tomcat 7 上运行它。 我发布了代码，即使它不是我修改的(默认)。

我在浏览器中使用的每个 URL 都遇到相同的错误。 我错过了什么吗？

我对 tomcat maven 插件一无所知，但是通过 pom 中的配置，端口似乎设置为 13000 并且上下文路径设置为 jaxrs-服务。

在命令行运行mvn tomcat7:run-war，如下成功

http://localhost:13000/jaxrs-service/hello/echo/Whatever

我相信单元测试应该作为 intergration-test 目标运行。你可以运行

mvn integration-test

它应该启动一个服务器，你应该在最后看到

Tests run: 2, Failures: 0, Errors: 0, Skipped: 0

我相信上述解决方案会启动一个嵌入式容器，而不是您实际的本地实例。如果您从本地实例启动应用程序，则 url 应该是

http://localhost:8080/<name-of-war>/hello/echo/Whatever
