我无法让 Jackson 在我的 Spring 应用程序中工作。

我在用着

  • 春天MVC 3.1.2
  • 杰克逊 1.9.1 映射器 asl

我已将 Jackson 库添加到 /WEB-INF/lib/ 文件夹并添加到我的 spring 配置文件中。

弹簧配置.xml

<!-- language: xml-->
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="
    http://www.springframework.org/schema/beans

    http://www.springframework.org/schema/mvc
    http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd">

<mvc:annotation-driven />

<context:component-scan base-package="com.mason.server.controller"  />

<bean
   class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="prefix">
        <value>/WEB-CONTENT/</value>
    </property>
    <property name="suffix">
        <value>.jsp</value>
    </property>
</bean>

<bean id="messageSource" class="org.springframework.context.support.ReloadableResourceBundleMessageSource">
   <property name="basename" value="WEB-INF/messages/messages" />
</bean>

控制器中的功能

<!-- language: java -->
@RequestMapping(value = "/get_json", method = RequestMethod.GET, headers = "Accept=*/*")
public @ResponseBody List<String> getTechList() {
    List<String> countryList = new ArrayList<String>();

    countryList.add("test");

    return countryList;
}

当我转到 localhost:8888/get_json 时，我收到错误 406。

我在互联网上尝试了一种解决方案，但似乎都没有奏效。任何帮助，将不胜感激！

PS：我将 Spring MVC 与 Google App Engine 和 Spring Security 结合使用。

2天后我让它工作了。我忘了将jackson-core-asl-1.9.10添加到我的库中，当我使用 jQuery 发出请求时，一切正常。它无法转到浏览器中的链接，但我想现在没问题。

mvc-config.xml
