SpringMVC ajax请求406 错误解决方案：
在springMVC配置文件中添加以下代码：
<!--避免ajax请求出现406错误-->
<bean id="contentNegotiationManager" class="org.springframework.web.accept.ContentNegotiationManagerFactoryBean">
<property name="favorPathExtension" value="false"/>
<property name="favorParameter" value="false"/>
<property name="ignoreAcceptHeader" value="false"/>
<property name="mediaTypes">
<value>
atom = application/atom+xml
html = text/html
json = application/json
* = */*
</value>
</property>
</bean>
<mvc:annotation-driven content-negotiation-manager="contentNegotiationManager" >
<mvc:message-converters register-defaults="true">
<bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
<property name="supportedMediaTypes">
<list><value>text/html;charset=UTF-8</value></list>
</property>
</bean>
</mvc:message-converters>
</mvc:annotation-driven>如果是maven项目需要在pom.xml 添加如下依赖：（不是maven项目就需要，自行下载咯）
<!--JSON:jackson-->
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-core</artifactId>
<version>${jackson-version}</version>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>${jackson-version}</version>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-annotations</artifactId>
<version>${jackson-version}</version>
</dependency>pom.xml中添加版本信息：
<!-- 版本号 -->
<properties>
<spring-version>4.1.6.RELEASE</spring-version>
<org.slf4j-version>1.6.1</org.slf4j-version>
<!-- JSON:jackson -->
<jackson-version>2.6.3</jackson-version>
