无法启用 spring 框架的日志记录

Question

我想在 Spring 框架和 Spring 安全性中配置登录，然后按照这个 http://docs.spring.io/spring/docs/3.2.x/spring-framework-reference/html/overview.html#overview-not-using-commons-logging

但是当我加载 Tomcat 时我遇到了这个问题：

Answer 1

我解决了问题！！

首先，这个错误：

GRAVE: A child container failed during start java.util.concurrent.ExecutionException: org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Catalina].StandardHost[localhost].StandardContext[/RH-Explore]]

是部署问题，所以我对项目进行了清理，然后出现此错误：

Grave: Exception lors de l'envoi de l'évènement contexte initialisé (context initialized) à l'instance de classe d'écoute (listener) org.springframework.web.context.ContextLoaderListener java.lang.AbstractMethodError: org.slf4j.impl.JDK14LoggerAdapter.log(Lorg/slf4j/Marker;Ljava/lang/String;ILjava/lang/String;[Ljava/lang/Object;Ljava/lang/Throwable;)V

这个错误是SLF4J的兼容性问题，所以我把版本从1.5.8改成了1.7.12 而且我发现一些重复的 SLF4J 包应该从 pom.xml 罐子中删除，因为这个错误：

SLF4J: Class path contains multiple SLF4J bindings.

启动时控制台也出现这个错误 tomcat:

INFOS: No Spring WebApplicationInitializer types detected on classpath

这是 servlet-api 中的一个问题，我使用的是 2.5 版本，所以为了解决这个问题，我更改为 3.0.1

版本

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <version>3.0.1</version>
</dependency>

所有问题都消失了，spring 日志记录工作正常 :D

无法启用 spring 框架的日志记录

can't enable logging of spring framework
