在Eclipse运行旧的springmvc程序，org.springframework-spring-webmvc版本3.1.2。
程序中的一个json文件出现错误：Expected value at 1:0
程序运行后（eclipse的jetty插件），出现下面的错误：
Unexpected exception parsing XML document from file
nested exception is java.lang.NoClassDefFoundError:
org/springframework/http/converter/json/MappingJackson2HttpMessageConverter
参考了下面3篇博文，可都没有结局此问题：
Spring集成JSON报错：java.lang.ClassNotFoundException: org.codehaus.jackson.JsonProcessingException

Springmvc 中org.springframework.http.converter.json.MappingJackson2HttpMessageConverter依赖jackson包

导入项目启动报错Unexpectedexception parsing XML document from file[H:\software\apache-tomcat-7.0.77\webapps

安装了JDK7，不能运行；
安装了Tomcat 7，也不能运行；
MappingJackson2HttpMessageConverter到底要怎么获得呢？
要用这个，不是的springframework 4.*吗？我这里却是3.1啊！
HELP！
问题补充：
nested exception is java.lang.NoClassDefFoundError: org/springframework/http/converter/json/MappingJackson2HttpMessageConverter
org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Failed to import bean definitions from URL location [classpath:prj-part1-*.xml]|Offending resource: ServletContext resource [/WEB-INF/prj-part1-servlet.xml]; nested exception is org.springframework.beans.factory.BeanDefinitionStoreException: Unexpected exception parsing XML document from file
