Error creating bean with name 'org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter#0': Cannot create inner bean '(inner bean)' of type [org.springframework.http.converter.json.MappingJacksonHttpMessageConverter] while setting bean property 'messageConverters' with key [5]; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name '(inner bean)#7': Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [org.springframework.http.converter.json.MappingJacksonHttpMessageConverter]: Constructor threw exception; nested exception is java.lang.NoSuchMethodError: org.codehaus.jackson.type.JavaType.<init>(Ljava/lang/Class;)VCaused by: java.lang.NoSuchMethodError: org.codehaus.jackson.type.JavaType.<init>(Ljava/lang/Class;)Vjava.lang.NoSuchMethodError: org.codehaus.jackson.type.JavaType.<init>(Ljava/lang/Class;)V

出现上述错误的原因是Spring中的com.springsource.org.codehaus.jackson.mapper-1.0.0和我们下载导入工程的jackson-all-1.9.11产生冲突，所以只需要把Spring中的com.springsource.org.codehaus.jackson.mapper-1.0.0删除即可
