Implementing a Provider | 实现提供者

public class Slf4jLogProvider implements LogProvider {
    @Override
    public String getName() { return "SLF4J"; }

    @Override
    public int getPriority() { return 10; } // Lower = higher priority

    @Override
    public boolean isAvailable() {
        try {
            Class.forName("org.slf4j.LoggerFactory");
            return true;
        } catch (ClassNotFoundException e) {
            return false;
        }
    }

    @Override
    public Logger getLogger(String name) {
        return new Slf4jLoggerAdapter(org.slf4j.LoggerFactory.getLogger(name));
    }

    @Override
    public MDCAdapter getMDCAdapter() {
        return new Slf4jMDCAdapter();
    }
}
