搭建的过程参考CSDN上的一篇文章 SSM框架——详细整合教程（Spring+SpringMVC+MyBatis），在此教程之上将dbcp数据源替换为druid，更改事务管理相关配置 以及包结构的划分 等。
在处理SpringMVC返回的JSON的时候，按照教程上所写配置如下：
<!-- 避免IE执行AJAX时，返回JSON出现下载文件 -->
<bean id="mappingJacksonHttpMessageConverter"
class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">
<property name="supportedMediaTypes">
<list>
<value>text/html;charset=UTF-8</value>
</list>
</property>
</bean>
<!-- 映入JSON -->
<dependency>
<groupId>org.codehaus.jackson</groupId>
<artifactId>jackson-mapper-asl</artifactId>
<version>1.9.13</version>
</dependency>细心一点就会发现在 jackson-mapper-asl.jar 中，找不到org.springframework.http.converter.json.MappingJacksonHttpMessageConverter 方法， 项目启动时果不其然报错了
Cannot find class [org.springframework.http.converter.json.MappingJacksonHttpMessageConverter] for bean with name 'mappingJacksonHttpMessageConverter' defined in class path resource [spring-mvc.xml];
.....最终在 Stack Overflow 上找到的答案：
Also MappingJacksonHttpMessageConverter is deprecated in 4.0.0 there is something newer. And you will need to add dependencies for jackson as well to get things working.
原文地址：
- classnotfoundexception-org-springframework-http-converter-json-mappingjacksonht
- jackson-2-0-with-spring-3-1 +
修改后的配置如下：
<!--避免IE执行AJAX时，返回JSON出现下载文件 -->
<bean id="mappingJacksonHttpMessageConverter"
class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
<property name="supportedMediaTypes">
<list>
<value>text/html;charset=UTF-8</value>
</list>
</property>
</bean>
<!-- jackson版本号 -->
