Javascript Jquery自动完成和Spring2.5.6的问题

我试图使用JQuery和Spring2.5.6显示自动完成列表，但是我将json放在前端，但是我无法显示它

 $(function() {
    $("#globalSearch").autocomplete({
        source: function(request, response) {
            $.ajax({
                url: "${pageContext.request.contextPath}/autoSearch.htm",
                data: {
                    term : request.term
                },
                dataType: "json",
                contentType: "application/json; charset=utf-8",
                success: function(data) {
                    // this is the alert output its displaying:{"list":["ernst","ernst&nbsp"]} 
                    alert(JSON.stringify(data, null, 4));
                    response($.map(data, function(item) {
                        //its not alerting anything here
                        alert(JSON.stringify(item, null, 4));
                        return{
                            value: item.list
                        };
                    }));
                }
            });
        }
    });
});

这是我的spring控制器代码：

@RequestMapping(method = RequestMethod.GET, value = "/autoSearch.htm")
public ModelAndView autoSearch(
        @RequestParam(value = "term", required = false) String term
       ) throws ParseException, IOException {

    if (logger.isDebugEnabled()) {
        logger.debug("inventoryHandler called");
    }

    Map<String, Object> model = new HashMap<String, Object>();
    int i = 0;
    model.put("list", getBaseModel().getSearchServiceBean().autoCompleter(term));
    return new ModelAndView("jsonView", model);
}

@RequestMapping（method=RequestMethod.GET，value=“/autoSearch.htm”）
公共模型和视图自动搜索(
@RequestParam（value=“term”，required=false）字符串术语
)抛出ParseException，IOException{
if（logger.isDebugEnabled（））{
debug（“调用inventoryHandler”）；
}
映射模型=新的HashMap（）；
int i=0；
put（“list”，getBaseModel（）.getSearchServiceBean（）.autoCompleter（术语））；
返回新的ModelAndView（“jsonView”，model）；
}

谁能告诉我如何显示自动完成列表

提前感谢,

致以最良好的祝愿，

Raja.

在Spring3.x以后的版本中，您将使用@ResponseBody注释，例如：

public @ResponseBody List<String> autocomplete(@RequestParam(value = "term", required = false) String term) {
    //Go get your results for the autocomplete term
    List<String> termResults = ...;

    return termResults;
}

最后我找到了下面显示的解决方案

 $(document).ready(function() {
    $("#globalSearch").autocomplete({
        source: function(request, response) {
            $.ajax({
                url: "${pageContext.request.contextPath}/autoSearch.htm",
                data: {
                    globalSearch : request.term
                },
                dataType: "json",
                contentType: "application/json; charset=utf-8",
                success: function(data) {
                    response($.map(data.list, function(value) {
                        return{
                            label: value,
                            value: value
                        };
                    }));
                }
            });
        }
    });
});

在输入字段中，名称和id必须相同

 <input type="text" name="globalSearch" id="globalSearch"/>

@RequestMapping（method=RequestMethod.GET，value=“/autoSearch.htm”） 公共模型和视图自动搜索( @RequestParam（value=“term”，required=false）字符串术语 )抛出ParseException，IOException{

    if (logger.isDebugEnabled()) {
        logger.debug("inventoryHandler called");
    }

    Map<String, Object> model = new HashMap<String, Object>();
    model.put("list", getBaseModel().getSearchServiceBean().searchAutoComplete(term));
    return new ModelAndView("jsonView", model);
}

实际上，我在前端得到了json。只是不知道如何返回它。但最终找到了解决方案，它显示在下面。

    if (logger.isDebugEnabled()) {
        logger.debug("inventoryHandler called");
    }

    Map<String, Object> model = new HashMap<String, Object>();
    model.put("list", getBaseModel().getSearchServiceBean().searchAutoComplete(term));
    return new ModelAndView("jsonView", model);
}

        $("#searchEmail").autocomplete({
            source: function(request, response) {
                ajaxCall(request, response);
            },
            select: function(event, ui) {
                $("#searchEmail").val(ui.item.value);
                $("#emailSearch-form").submit();
            }
        });

        function ajaxCall(request, response) {
            $.ajax({
                url: "${pageContext.request.contextPath}/autoSearch.htm",
                data: {
                    term : request.term
                },
                dataType: "json",
                contentType: "application/json; charset=utf-8",
                success: function(data) {
                    response($.map(data.list, function(item) {
                        return{
                            label: item,
                            value: item
                        };
                    }));
                }
            });
        }
