spring+jackson对java.lang.NoSuchMethodError的异常处理
spring MVC中通常使用jackson-core-asl-1.9.*.jar和jackson-mapper-asl-1.9.*.jar对json和javabaen进行转化，但通常情况下会出现下面的问题：
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter#0' defined in ServletContext resource [/WEB-INF/webmvc-servlet.xml]: Cannot create inner bean 'org.springframework.http.converter.json.MappingJacksonHttpMessageConverter#1bfbe41' of type [org.springframework.http.converter.json.MappingJacksonHttpMessageConverter] while setting bean property 'messageConverters' with key [1]; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.http.converter.json.MappingJacksonHttpMessageConverter#1bfbe41' defined in ServletContext resource [/WEB-INF/webmvc-servlet.xml]: 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;)V

而这种问题属于jar包冲突：jackson-mapper-asl-1.9.*.jar如spring自带的jar包com.springsource.org.codehaus.jackson.mapper-1.4.2.jar冲突，从而在项目初始中抛出上述异常。解决方法是将com.springsource.org.codehaus.jackson.mapper-1.4.2.jar移除。并删除服务器webapps/***/WEB-INF/lib包中的com.springsource.org.codehaus.jackson.mapper-1.4.2.jar。
spring MVC在使用jackson时一定要注意：jackson-core-asl-1.9.*.jar和jackson-mapper-asl-1.9.*.jar的版本号一定要相同，如：同时使用1.9.5。
