这是我的演示项目
1) 一个带有 3 个 java 文件的简单 RESTful 应用程序:
1.1) RestNotFoundExceptionHandler.java
package demo.app;
import javax.ws.rs.NotFoundException;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;
import javax.ws.rs.ext.ExceptionMapper;
import javax.ws.rs.ext.Provider;
@Provider
public class RestNotFoundExceptionHandler implements ExceptionMapper<NotFoundException> {
@Override
public Response toResponse(NotFoundException e) {
return Response.ok().entity(e.toString() + "\n").type(MediaType.TEXT_PLAIN).build();
}
}
1.2) AppRest.java
package demo.app;
import javax.servlet.http.HttpServletRequest;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.Context;
import javax.ws.rs.core.MediaType;
@Path("/")
public class AppRest {
@GET
@Path("millis")
@Produces(MediaType.TEXT_PLAIN)
public String refresh(@Context HttpServletRequest request) {
try {
return Long.toString(System.currentTimeMillis()) + "\n";
} catch (Exception e) {
return e.toString() + "\n";
}
}
}
1.3) AppMain.java
package demo.app;
import javax.ws.rs.NotFoundException;
import org.jboss.resteasy.plugins.server.tjws.TJWSEmbeddedJaxrsServer;
public class AppMain {
private static final int PORT = 8080;
public static void main(String[] args) {
AppRest appRest = new AppRest();
TJWSEmbeddedJaxrsServer tjws = new TJWSEmbeddedJaxrsServer();
tjws.setPort(PORT);
tjws.setRootResourcePath("/rest");
tjws.start();
tjws.getDeployment().getRegistry().addSingletonResource(appRest);
tjws.getDeployment().getProviderFactory().getExceptionMappers()
.put(NotFoundException.class, new RestNotFoundExceptionHandler());
}
}
2)项目依赖,4个jar文件
jaxrs-api-3.0.9.Final.jar
resteasy-jaxrs-3.0.9.Final.jar
servlet-api-2.5.jar
tjws-3.0.9.Final.jar
3)卷曲测试用例:
3.1) 正常情况:
$ curl http://127.0.0.1:8080/rest/millis
1419167594504
3.2) RestNotFoundExceptionHandler 案例:
$ curl http://127.0.0.1:8080/rest/bad
javax.ws.rs.NotFoundException: Could not find resource for full path: http://127.0.0.1:8080/rest/bad
