Spring4+springmvc+mybatis3
本人无聊时研究spring项目版本迁移出现的问题
关于Spring从3.x到4.x整改的过程报错问题进行修复
整体架构：spring+springmvc+mybatis+mysql
1.搭建一个简单的spring3.x版本项目
2.copy>spring3.x版本的项目
修改pom配置
1.将所有spring的版本改成 4.3.18.RELEASE
2.因为要用到json数据，将jackson-databind 版本改成 2.9.5
3.mybatis的版本改成 3.2.6
修改spring-mvc.xml
1.修改头部信息，可以将版本号去掉，这样默认是从jar包中寻找引用
http://www.springframework.org/schema/aop/spring-aop.xsd
2. <!--避免IE执行AJAX时，返回JSON出现下载文件 ；spring 4.0之前是 MappingJacksonHttpMessageConverter spring4.0之后的版本是MappingJackson2HttpMessageConverter -->
3.org.springframework.web.servlet.view.ContentNegotiatingViewResolver 改成 org.springframework.web.accept.ContentNegotiationManagerFactoryBean
上面是给我自己加深印象的，下面贴出配置文件
