springmvc中logback的配置

网上相关有关springmvc集成logback的帖子很多，在此记录配置过程中遇到的问题。

pom依赖如下

<dependency>
			<groupId>log4j</groupId>
			<artifactId>log4j</artifactId>
			<version>${log4j-version}</version>
		</dependency>
		<dependency>
			<groupId>org.slf4j</groupId>
			<artifactId>slf4j-api</artifactId>
			<version>${slf4j-api-version}</version>
		</dependency>

		<dependency>
			<groupId>ch.qos.logback</groupId>
			<artifactId>logback-classic</artifactId>
			<version>${logback-version}</version>
		</dependency>
		<dependency>
			<groupId>ch.qos.logback</groupId>
			<artifactId>logback-core</artifactId>
			<version>${logback-version}</version>
		</dependency>
		<dependency>
			<groupId>org.logback-extensions</groupId>
			<artifactId>logback-ext-spring</artifactId>
			<version>0.1.1</version>
		</dependency>

之前在http://mvnrepository.com/上找到的依赖（logback-classic）包含<scope>test</scope>，导致项目启动的时候，报异常（java.lang.NoClassDefFoundError: org/slf4j/impl/StaticLoggerBinder），将scope删除后，问题解决。
