我确实尝试通过以下链接 如何将合作者连接到泽西资源? 和 访问 Jersey Resource 类中的外部对象 但我仍然无法找到一个工作示例来显示如何注入到 Resource 类中。我没有使用 Spring 或 Web 容器。
我的资源是
package resource;
import javax.ws.rs.FormParam;
import javax.ws.rs.GET;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
@Path("/something")
public class Resource
{
@MyResource
Integer foo = null;
private static String response = "SampleData from Resource";
public Resource()
{
System.out.println("...constructor called :" + foo);
}
@Path("/that")
@GET
@Produces("text/plain")
public String sendResponse()
{
return response + "\n";
}
}
我的提供者是
package resource;
import javax.ws.rs.ext.Provider;
import com.sun.jersey.core.spi.component.ComponentContext;
import com.sun.jersey.core.spi.component.ComponentScope;
import com.sun.jersey.spi.inject.Injectable;
import com.sun.jersey.spi.inject.InjectableProvider;
@Provider
public class MyResourceProvider implements InjectableProvider<MyResource, Integer>
{
@Override
public ComponentScope getScope()
{
return ComponentScope.PerRequest;
}
@Override
public Injectable getInjectable(final ComponentContext arg0, final MyResource arg1, final Integer arg2)
{
return new Injectable<Object>()
{
@Override
public Object getValue()
{
return new Integer(99);
}
};
}
}
我的 EndpointPublisher 是
import java.util.HashMap;
import java.util.Map;
import javax.ws.rs.core.MediaType;
import com.sun.jersey.api.client.Client;
import com.sun.jersey.api.client.ClientResponse;
import com.sun.jersey.api.client.WebResource;
import com.sun.jersey.api.container.grizzly.GrizzlyWebContainerFactory;
class EndpointPublisher
{
public static void main(final String[] args)
{
final String address = "http://localhost:8080/";
final Map<String, String> config = new HashMap<String, String>();
config.put("com.sun.jersey.config.property.packages", "resource");
try
{
GrizzlyWebContainerFactory.create(address, config);
System.out.println("server started ....." + address);
callGet();
}
catch (final Exception e)
{
e.printStackTrace();
}
}
public static void callGet()
{
Client client = null;
ClientResponse response = null;
client = Client.create();
final WebResource resource =
client.resource("http://localhost:8080/something");
response = resource.path("that")
.accept(MediaType.TEXT_XML_TYPE, MediaType.APPLICATION_XML_TYPE)
.type(MediaType.TEXT_XML)
.get(ClientResponse.class);
System.out.println(">>>> " + response.getResponseDate());
}
}
我的注释是
@Retention(RetentionPolicy.RUNTIME)
public @interface MyResource
{}
但是当我执行我的 EndpointPublisher 时,我无法注入 foo!
