春天mvc ajax json有时畸形

Question

使用的库

1. spring.4.3.4 jar
2. jquery 1.9.1
3. gson-2.2.2 jar

使用JDBCTemplate

控制器

@RequestMapping(value = "user/getApmcBudgTransData", method = RequestMethod.POST, produces = "application/json; charset=UTF-8")
    public @ResponseBody String getUserLevelMasterDetails(HttpServletRequest request,HttpServletResponse res) { 
        ModelAndView model = new ModelAndView();
        String yrmstid=request.getParameter("finyrMstid");
        String apmcid=request.getParameter("apmcid");
        String sendToOfc = request.getParameter("sendToOfc");   
        String opFlag = request.getParameter("opFlag"); 
        String formType = request.getParameter("formType"); 
        ArrayList<ApmcBudgTransaction> apmcBudgtrandata=budgetService.getApmcBudgTransData(apmcid, yrmstid, sendToOfc, opFlag, formType);       

        Gson gson = new Gson();
        return gson.toJson(apmcBudgtrandata);
    }

JSP ajax调用

                  $.ajax({
                    url:"${pageContext.request.contextPath}/user/getApmcBudgTransData",
                    type:'post',  
                    dataType: 'json',
                    async:false,
                    data: {
                        finyrMstid :lastyr,
                        apmcid : pkvalue,
                        sendToOfc : "APMC",
                        opFlag : flag,
                        formType : "S"
                     },
                   success: function(resp) {},
                   error: function(err) {}

                   });

弹簧servlet.xml中

<?xml version="1.0" encoding="UTF-8"?>
<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"

    <context:annotation-config />

    <mvc:annotation-driven />
    <mvc:default-servlet-handler />


    <mvc:interceptors>


    <bean id="webContentInterceptor" 
          class="org.springframework.web.servlet.mvc.WebContentInterceptor">
        <property name="cacheSeconds" value="0"/>
        <property name="useExpiresHeader" value="true"/>
        <property name="useCacheControlHeader" value="true"/>
        <property name="useCacheControlNoStore" value="true"/>
    </bean>
    </mvc:interceptors>


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



</beans>    

ajax调用正在从控制器接收大量的utf-8 json数据。

json在控制器中每次都很好。

当控件返回到ajax调用时，第一次，json格式错误并调用错误函数。

第二次以及随后的每一次，json都处于良好状态，并且调用了成功函数。

我不能因为喜欢编程而弄清楚为什么会这样。
