ssm实战——SpringMVC异常java.lang.NoClassDefFoundError: com/fasterxml/jackson/core/JsonProcessingException

出现此异常，在pom.xml中添加如下依赖解决：

		<dependency>
			<groupId>com.fasterxml.jackson.core</groupId>
			<artifactId>jackson-databind</artifactId>
			<version>2.7.4</version>
		</dependency>
		<dependency>
			<groupId>com.fasterxml.jackson.core</groupId>
			<artifactId>jackson-core</artifactId>
			<version>2.7.4</version>
		</dependency>
        	<dependency>
			<groupId>com.fasterxml.jackson.core</groupId>
			<artifactId>jackson-annotations</artifactId>
			<version>2.7.4</version>
		</dependency>

说明：jackson-annotations和jackson-databind依赖于jackson-databind

pom只加入jackson-databind依赖也可以
