我在这里几次发现同样的问题,但我找不到答案。
当我运行我的应用程序时,我收到以下错误

这是项目的pom文件(我只添加了主要部分)

这是我的 Test.java 类
@Path("/TestClass")
public class Test implements Serializable{
private static final long serialVersionUID = -262701666015379272L;
@GET
@Path("/hello")
public Response heloMessage() {
String result = "Hello Word!!!!!!!!!";
return Response.status(200).entity(result).build();
}
}
请告诉我,我哪里做错了?提前致谢
答案 0 :(得分:2)
我没有机会测试你的版本(使用web.xml),说实话,当我做使用Resteasy时,我对xml的工作量不大,所以我不会试着用web.xml解释什么是错的(如果有的话)。
但是当使用javax.xs.rs.core.Application
子类时,我们可以定义@ApplicationPath("/path")
注释。这为我们的JAX-RS应用程序定义了一个servlet,其url映射为/path/*
。这在JAX-RS规范中指定。
您可以在2.3.2 Configuration - Servlet部分中详细了解此部署选项以及其他选项。这是1.1规范(您使用的是2.0),但部署选项类似。我只是找不到2.0的HTML链接。您可以从here下载pdf。
您还可以阅读有关Resteasy here in the documentation的部署的更多信息。
但基本上,此部署选项的作用是扫描应用程序的@Path
,@Provider
等注释。原因是JAX-RS将首先分别在重写getClasses()
和getSingletons()
中查找类和对象。如果然后返回空集,则告诉JAX-RS进行扫描(根据规范)。
