Corrígeme si tengo algo mal pero esto debería funcionar ?! Solo obtengo en mi eclipse esta excepción

¿Qué problema hay en mi configuración?

Answer 1

Incluir el slf4j-api en sus dependencias:

<dependency> 
    <groupId>org.slf4j</groupId> 
    <artifactId>slf4j-api</artifactId> 
    <version>1.5.8</version> 
</dependency> 

Excluir la dependencia commons-logging para un mínimo de uno de sus dependencias primavera declarados y proporcionar la fachada slf4j para commons-logging:

<dependency> 
    <groupId>org.springframework</groupId> 
    <artifactId>spring-context</artifactId> 
    <version>3.0.2.RELEASE</version> 
    <exclusions> 
    <exclusion> 
     <groupId>commons-logging</groupId> 
     <artifactId>commons-logging</artifactId> 
    </exclusion> 
    </exclusions> 
</dependency> 
<dependency> 
    <groupId>org.slf4j</groupId> 
    <artifactId>jcl-over-slf4j</artifactId> 
    <version>1.5.8</version> 
    <scope>runtime</scope> 
</dependency> 

Incluya la dependencia log4j para su registro junto con la fachada slf4j:

<dependency> 
    <groupId>org.slf4j</groupId> 
    <artifactId>slf4j-log4j12</artifactId> 
    <version>1.5.8</version> 
    <scope>runtime</scope> 
</dependency> 
<dependency> 
    <groupId>log4j</groupId> 
    <artifactId>log4j</artifactId> 
    <version>1.2.14</version> 
    <scope>runtime</scope> 
</dependency> 

Una gran publicación de blog para leer más sobre el inicio de sesión con SLF4J y Spring se puede encontrar en el blog del equipo de SpringSource bajo http://blog.springsource.com/2009/12/04/logging-dependencies-in-spring/.

Answer 2

Esto debería funcionar, el slf4j-log4j12 vinculante contiene org/slf4j/impl/StaticLoggerBinder.

1. Trate de limpiar y volver a implementar su aplicación, tal vez algo salió mal durante la implementación.
2. Compruebe que el slf4j-log4j12-1.5.8.jar descargado no está dañado (intente abrirlo).
3. Quizás incluso lo elimine y deje que maven vuelva a descargarlo.

Algunas observaciones no relacionadas:

• En vez de repetir la versión marcos en las dependencias, se debe utilizar una propiedad. Por ejemplo:

  ... 
  <properties> 
      <spring.version>3.0.2.RELEASE</spring.version> 
      ... 
  </properties> 
  <dependencies> 
      <dependency> 
      <groupId>org.springframework</groupId> 
      <artifactId>spring-core</artifactId> 
      <version>${spring.version}</version> 
      </dependency> 
      ... 
  </dependencies> 
  

• hibernate-core es una dependencia transitiva de hibernate-annotations, no es necesario declarar que (si se desea utilizar la APP, en realidad se debe depender de hibernate-entitymanager).

Answer 3

Te faltan

<dependency> 
    <groupId>org.slf4j</groupId> 
    <artifactId>slf4j-api</artifactId> 
    <version>1.5.8</version> 
    </dependency> 

Answer 4

hibernación depende de slf4j-API, por lo que se declara a sí mismo que no debe hacer ninguna diferencia. Aparte de eso, no sé por qué no está funcionando.
