Spring mvc 報406 (Not Acceptable) 錯誤

1、定義version
 <properties>
      <jackson.version>2.4.4</jackson.version>
 </properties>
2、依賴包
<dependency>
        <groupId>com.fasterxml.jackson.core</groupId>
        <artifactId>jackson-core</artifactId>
        <version>${jackson.version}</version>
    </dependency>
    <dependency>
        <groupId>com.fasterxml.jackson.core</groupId>
        <artifactId>jackson-annotations</artifactId>
        <version>${jackson.version}</version>
    </dependency>
    <dependency>
        <groupId>com.fasterxml.jackson.core</groupId>
        <artifactId>jackson-databind</artifactId>
        <version>${jackson.version}</version>
    </dependency>

3、而後使用spring mvc的默認配置便可返回json，爲了不IE執行ajax時，返回json出現下載文件的問題，spring-mvc.xml可以使用以下配置：

<!-- 避免IE執行ajax時，返回json出現下載文件 -->
<bean id="mappingJacksonHttpMessageConverter"
        class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
        <property name="supportedMediaTypes">
            <list>
                <value>text/html;charset=UTF-8</value>
            </list>
        </property>
    </bean> -->

    <!-- 啓動SpringMVC的註解功能，完成請求和註解POJO的映射 -->
    <bean
        class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
        <property name="messageConverters">
            <list>
                <!-- json轉換器 -->
                <ref bean="mappingJacksonHttpMessageConverter" />
            </list>
        </property>
    </bean>
