Question

我遇到让Jackson在我的Spring应用程序中工作的问题。

我正在使用

Spring MVC 3.1.2
Jackson 1.9.1 mapper 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-config.xml中

<!-- 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/beans/spring-beans-3.1.xsd
    http://www.springframework.org/schema/context 
    http://www.springframework.org/schema/context/spring-context-3.1.xsd
    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;
}

当我去localhost时：8888 / get_json我收到错误406。

我在互联网上尝试过一种解决方案，但似乎都没有。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。

我在2天后就开始工作了。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。它无法在浏览器中访问链接，但我想现在还可以。
