Я создаю веб-проект на Java, используя maven в IDEA. В проекте используется SSM framework. Я уже добавил slf4j-api 1.7.21, slf4j-simple 1.7.21 в pom.xml
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>1.7.21</version> <!-- or use LATEST -->
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-simple</artifactId>
<version>1.7.21</version> <!-- or use LATEST -->
</dependency>
, но все равно есть ошибка
«SLF4J: Не удалось загрузить класс»org.slf4j.impl.StaticLoggerBinder». SLF4J: По умолчанию используется логгер без операций (NOP) SLF4J: Подробнее см. http://www.slf4j.org/codes.html#StaticLoggerBinder.
