<dependency>
 <groupId>org.codehaus.jackson</groupId>
 <artifactId>jackson-mapper-asl</artifactId>
 <version>${jackson-mapper-asl.version}</version>
</dependency>

<dependency>
 <groupId>com.fasterxml.jackson.core</groupId>
 <artifactId>jackson-databind</artifactId>
 <version>${jackson-databind.version}</version>
</dependency>这俩个是同一个jar包的不一样版本,会出现和Spring的不一样版本的兼容问题,因此换一下jkson的版本就行了
