我需要知道如何在WebSphere Application Server环境(版本8.0和8.5)上覆盖默认的JSON提供程序.由于杰克逊图书馆版本1.6( https://github.com/FasterXML/jackson-module-jaxb-annotations/issues/3 ).

I need to know how to override the default JSON Provider on a WebSphere Application Server Environment (versions 8.0 and 8.5). I need to do that due a to an issue found on Jackson library version 1.6 (https://github.com/FasterXML/jackson-module-jaxb-annotations/issues/3).

如果有人能提供帮助，那将是非常受欢迎的.

If anyone could help would be more than welcome.

推荐答案

无论您是想完全避免使用Jackson还是只想使用其他版本，我都不太明白.

I did not quite get whether you want to avoid using Jackson at all or you just want a different version.

在您的应用程序中，您可以注册所需的提供者.例如，要使用Jettison，您需要满足以下条件:

In your application you can register the providers you want. For example, to use Jettison you need the following:

import org.apache.wink.providers.jettison.JettisonJAXBProvider;

import javax.ws.rs.core.Application;
import java.util.HashSet;
import java.util.Set;

public class YourApplication extends Application {

    @Override
    public Set<Object> getSingletons() {
        Set<Object> singletons = new HashSet<Object>();
        JettisonJAXBProvider jaxbProvider = new JettisonJAXBProvider();
        singletons.add(jaxbProvider);
        return singletons;
    }
}

如果您需要其他Jackson版本，为什么不将其放入WEB-INF/lib并将Web模块类加载策略设置为PARENT_LAST?

If you need different Jackson version, why not just put it into WEB-INF/lib and set web module classloading policy to PARENT_LAST?
