Question

嗨，我是maven的新手，无法运行我的项目。它为映射的资源抛出了404.

我有2个班级：

@ApplicationPath("webapi")
public class MyApp extends Application {

}

这些是我得到的错误。无法弄清楚出了什么问题。 Java编译器级别与已安装的Java项目构面的版本不匹配。 JAX-RS（REST Web服务）2.0需要Java 1.6或更高版本一个或多个约束条件尚未得到满足。

我正在使用jdk 1.8.0_111我试图把它放在maven中并尝试了$ {jdk.version}我试过[1.8.0_111]也给出了同样的错误。它正确加载欢迎页面但给404资源URI。在pom.xml中有什么问题吗？

@Path("hello")
public class MyResource {

@GET
@Produces(MediaType.TEXT_PLAIN)
public String testMethod() {
    return "Hello World";
    }
}

只有1.8作为编纂单位，它无法启动tomcat。

发布如果您发现任何异常，则需要在代码中解决。

还要确保您的jar文件没有损坏。如果它已损坏或无法解压缩，则会发生此错误。在这种情况下，请尝试删除现有的jar并重新构建。
