Ошибка создания Bean Spring MVC

Question

Я занимаюсь созданием портала с использованием Spring 4.2.4 и hibernate 4.2.21 Final с использованием maven. Я столкнулся со следующим исключением. Я не мог понять, что делает ошибка. Я не использую hibernate.cfg.xml, когда я делаю детали конфигурации внутри сервлета диспетчера. Также, как показывает трассировка стека ошибок, он не смог найти путь к модели. Ярцы, которые я добавил через maven, отображаются на рисунке ниже.

Это структура каталогов моего приложения

Как и в структуре папок, имеется employee.java как модель. Я не нахожу, где я ошибся.

Исключение

HTTP Status 500 - Servlet.init() for servlet hr-servlet threw exception 


type Exception report 

message Servlet.init() for servlet hr-servlet threw exception

Может кто-нибудь просветить меня, где я делаю ошибку? Я простаивал эту проблему часами.

SLF4J - это только интерфейс для ведения журнала. Вам нужна реализация. Log4j - общий выбор, но there are some others.

Если вы используете SLF4J с log4j, вы можете использовать log4j.properties файл с содержимым, приведенным ниже:

# Global logging configuration (Options DEBUG, INFO, WARN, ERROR, OFF) 
log4j.rootLogger=INFO,stdout,fichier,spring 
# mail à ajouter pour que les emails d'alerte sur erreur soient envoyés 


# Console output... 
log4j.appender.stdout=org.apache.log4j.ConsoleAppender 
log4j.appender.stdout.Threshold=INFO 
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout 
log4j.appender.stdout.layout.ConversionPattern=%d{dd/MM/yyyy HH:mm:ss} %-5p %x - %m%n 
#log4j.appender.stdout.layout.ConversionPattern=%5p [%t] - %m%n 

log4j.appender.fichier=org.apache.log4j.RollingFileAppender 
log4j.appender.fichier.Threshold=INFO 
log4j.appender.fichier.File=/var/log/tomcat/spring-web-mvc-json.log 
log4j.appender.fichier.layout=org.apache.log4j.PatternLayout 
log4j.appender.fichier.layout.ConversionPattern=%d{dd/MM/yyyy HH:mm:ss} %-5p %x - %m%n 
log4j.appender.fichier.MaxFileSize=5000KB 
log4j.appender.fichier.MaxBackupIndex=10 

log4j.appender.spring=org.apache.log4j.RollingFileAppender 
log4j.appender.fichier.Threshold=DEBUG 
log4j.appender.spring.File=/var/log/tomcat/spring-details.log 
log4j.appender.spring.layout=org.apache.log4j.PatternLayout 
log4j.appender.spring.layout.ConversionPattern=%d{dd/MM/yyyy HH:mm:ss} %-5p %x - %m%n 
log4j.appender.spring.MaxFileSize=5000KB 
log4j.appender.spring.MaxBackupIndex=10

Я думаю, что это может помочь вам создать эти файлы с содержанием данного :)
