I don't understand why, How can I fix it ? 我不明白为什么,该如何解决?
You have to access your resource with POST because you annotate your method with @POST
. 您必须使用POST访问资源,因为您使用
@POST
注释了方法。
If you enter the URL http://localhost:8080/jersey/rest/UserService/getUser
in your browser then a GET will be executed and a resource with the given name and GET as verb is not found. 如果您输入的URL
http://localhost:8080/jersey/rest/UserService/getUser
在浏览器中,然后一个GET将被执行,以给定名称的资源并获得尽可能动词是找不到的。
You have to create either a client or get a plugin for your browser to test REST services. 您必须为浏览器创建客户端或获取插件才能测试REST服务。
Be sure to have all following dependencies in your project : -jersey-container-servlet-core -jersey-media-json-processing -jersey-media-json-jackson 确保项目中具有以下所有依赖项:-jersey-container-servlet-core -jersey-media-json-processing -jersey-media-json-jackson
create a configuration class for your rest webservice, you can also load your package to be scan by jersey in those class, instead in web.xml 为您的其余Web服务创建配置类,也可以在这些类中加载要由jersey扫描的包,而不是在web.xml中
import org.glassfish.jersey.jackson.JacksonFeature; import org.glassfish.jersey.server.ResourceConfig; public class Application extends ResourceConfig { public Application(){ packages("com.package.of.your.resources"). register(JacksonFeature.class); } }
Don't forget to add the following annotation @XmlRootElement
to your DAO class 不要忘记在您的DAO类中添加以下注释
@XmlRootElement
@Path('getUser')
is enough. @Path('getUser')
就足够了。
