A problem occurred:

slf4j:failed to load Class "Org.slf4j.impl.StaticLoggerBinder".
Slf4j:defaulting to No-operation (NOP) Logger implementation
Slf4j:see Http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

The cause of the problem is the inability to find org.slf4j.impl.StaticLoggerBinder, the official answer Http://www.slf4j.org/codes.html#StaticLoggerBinder:

This error was reported when the org.slf4j.impl.StaticLoggerBinder class could wasn't being loaded into memory. This happens when no appropriate slf4j binding could is found on the class path. Placing one (and only one) of Slf4j-nop.jar, slf4j-simple.jar,Slf4j-log4j12.jar, Slf4j-jdk14.jar or Logback-classic.jar on the class path should solve the problem .

You can download slf4j bindings from the Project download page.

The main idea is that it org.slf4j.impl.StaticLoggerBinder cannot be loaded into memory because it does not find a suitable binding slf4j and needs to add one of the listed packages.

Here's how to fix it:

Download Slf4j-nop.jar, add to path, solve the problem

Workaround:

Import slf4j-nop.jar, slf4j-simple.jar,slf4j-log4j12.jar , Slf4j-jdk14.jar or logback-classic.jar any one.

MAVEN relies on the notation:

<Dependency>
<GroupId>org.slf4j</groupId>
<artifactid>slf4j-simple</artifactid>
<version>1.7.6</version>
</Dependency>
