ajax 请求时后台SpringMVC返回List集合时报406错误解决办法

首先在maven中引入json的3个jar包

 

<dependency>
            <groupId>com.fasterxml.jackson.core</groupId>
            <artifactId>jackson-databind</artifactId>
            <version>2.6.3</version>
        </dependency>
   
        <dependency>
            <groupId>com.fasterxml.jackson.core</groupId>
            <artifactId>jackson-core</artifactId>
            <version>2.6.3</version>
        </dependency>
        <dependency>
            <groupId>org.codehaus.jackson</groupId>
            <artifactId>jackson-mapper-asl</artifactId>
            <version>1.9.13</version>
</dependency>

 

 

Spring-mvc.xml中加入如下配置：

 

<mvc:annotation-driven content-negotiation-manager="contentNegotiationManager"/>
    <bean id="contentNegotiationManager" class="org.springframework.web.accept.ContentNegotiationManagerFactoryBean">
        <property name="favorPathExtension" value="false" />
    </bean>
    <bean id="jsonConverter" class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter"></bean> 

    <bean id="stringConverter" 
        class="org.springframework.http.converter.StringHttpMessageConverter"> 
        <property name="supportedMediaTypes"> 
            <list> 
                <value>text/plain;charset=UTF-8</value> 
            </list> 
        </property> 
    </bean> 

    <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"> 
        <property name="messageConverters"> 
            <list> 
                <ref bean="stringConverter" /> 
                <ref bean="jsonConverter" /> 
            </list> 
        </property> 
    </bean>
