本文介绍了Resin4应用服务器与Slf4j日志框架之间的版本兼容性问题，当Resin4所需的Slf4j版本为1.6+时，使用早期版本会导致NoSuchMethodError异常。文章提供了异常的详细信息及解决方法。

Resin4对 slf4j的要求是version 1.6+，所以如果3换4的话要记得升级jar包，否则活抛异常，异常信息如下：

NoSuchMethodError: StaticLoggerBinder.getSingleton()

对应的org.slf4j.LoggerFactory源码如下：

private final static void bind() {
     try {
       // the next line does the binding
       StaticLoggerBinder.getSingleton();
       INITIALIZATION_STATE = SUCCESSFUL_INITILIZATION;
       emitSubstituteLoggerWarning();
     } catch (NoClassDefFoundError ncde) {
       String msg = ncde.getMessage();
       if (msg != null && msg.indexOf("org/slf4j/impl/StaticLoggerBinder") != -1) {
         INITIALIZATION_STATE = NOP_FALLBACK_INITILIZATION;
         Util
             .report("Failed to load class \"org.slf4j.impl.StaticLoggerBinder\".");
         Util.report("Defaulting to no-operation (NOP) logger implementation");
         Util.report("See " + NO_STATICLOGGERBINDER_URL
             + " for further details.");
       } else {
         failedBinding(ncde);
         throw ncde;
       }
     } catch(java.lang.NoSuchMethodError nsme) {
       String msg = nsme.getMessage();
       if (msg != null && msg.indexOf("org.slf4j.impl.StaticLoggerBinder.getSingleton()") != -1) {
         INITIALIZATION_STATE = FAILED_INITILIZATION;
         Util.report("slf4j-api 1.6.x (or later) is incompatible with this binding.");
         Util.report("Your binding is version 1.5.5 or earlier.");
         Util.report("Upgrade your binding to version 1.6.x. or 2.0.x");
       }
       throw nsme;
     } catch (Exception e) {
       failedBinding(e);
       throw new IllegalStateException("Unexpected initialization failure", e);
     }
   }

在进行bind的时候
