Question

How can I enforce a queue to be browse only in Red Hat MRG/Apache QPID so that clients can only browse the queue. Even if some client tries to consume message off queue, he should not be able to do it.

我不认为有这样的选择,可以召集中间商,但你的客户能够以只靠浏览的方式与中间商联系。

direct://amq.direct//myqueue?browse=true

使客户使用浏览器的另一种方式是只处理。

package foo.bar;

import java.util.Hashtable;
import java.util.Map;

import org.apache.qpid.client.AMQDestination;
import org.apache.qpid.jndi.PropertiesFileInitialContextFactory;
import org.apache.qpid.jndi.ReadOnlyContext;

public class CustomPropertiesFileInitialContextFactory extends PropertiesFileInitialContextFactory {

    @SuppressWarnings({ "rawtypes", "unchecked" })
    @Override
    protected ReadOnlyContext createContext(Map data, Hashtable environment) {
        makeDestinationsReadOnly(data);
        return super.createContext(data, environment);
    }
    protected void makeDestinationsReadOnly(Map<String, AMQDestination> dests) {
        for(AMQDestination dest : dests.values()) {
            dest.setBrowseOnly(true);
        }
    }
}
