無法從Spring MVC中獲取列表爲Ajax響應

Question

無法獲取列表進入從Spring MVC的Ajax響應得到406（不接受），但能夠得到的字符串，在這裏我的代碼

@ResponseStatus(value = HttpStatus.OK) 
@RequestMapping(value = "/getCategory", method = RequestMethod.POST, headers = "Accept=*/*", produces = "application/json") 
public @ResponseBody List<Info> initCategory(@ModelAttribute(value = "getCategories") Info info) { 
    List<Info> category = null; 
    try { 
     category = infoService.getCategory(info.getPlantName()); 
    } catch (NullPointerException e) { 
     e.printStackTrace(); 
    } 
    return category; 
} 

阿賈克斯

function selectCategory() { 
     var plantId = $('#plantId').val(); 
     alert(plantId); 
     $.ajax({ 
        url : '/veQNL/addPro/getCategory', 
        type : 'POST', 
        data : $("#addProject").serialize(), 
        success : function(result) { 
         alert(result); 
        } 
     }); 
} 

和調度

<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"

    class="org.springframework.jdbc.datasource.DriverManagerDataSource"> 
    <property name="driverClassName" value="${database.driver}" /> 
    <property name="url" value="${database.url}" /> 
    <property name="username" value="${database.user}" /> 
    <property name="password" value="${database.password}" /> 
</bean> 

<bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate"> 
    <property name="dataSource" ref="dataSource" /> 
</bean> 
<mvc:resources mapping="/resources/**" location="/resources/" 
    cache-period="31556926" /> 
<mvc:annotation-driven /></beans> 

有無嘗試了很多東西像地圖，JSON等，但得到相同的，任何幫助將是appre ciate。

以下豆添加到您的配置：

<bean id="jacksonConverter" class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter" />
