这是ik的配置文件  在配置远程扩展字典写上下面方法的接口(要注意能调取到这个方法) 把停止词典注释掉
---------------------------------------------------------------------------



IK Analyzer 扩展配置

custom/mydict.dic;custom/single_word_low_freq.dic

custom/ext_stopword.dic

location

http://xxx.com/xxx.dic

---------------------------------------------------------------------------
以下是java代码部分
---------------------------------------------------------------------------
@GET
    @Path("loadGJCK")
    @Produces(MediaType.APPLICATION_OCTET_STREAM)
    @ApiOperation(value = "词库")
    public String  loadGJCK(@Context HttpServletRequest request,@Context HttpServletResponse response){
        String result = "";
        try {

            StringBuilder sb = new StringBuilder();
            String[] keywords = keywordService.selectKeyWord(10l);//获取所有分词，这里可以改进使用缓存等。

            String eTag = request.getHeader("If-None-Match");
            Long modified= request.getDateHeader("If-Modified-Since");

            //设置头
            if(null == modified || -1 == modified) {
                //如果没有，则使用当前时间
                modified = System.currentTimeMillis();
            }
            // 设置头信息。
            String oldEtag = keywords.length+ "";
            response.setDateHeader("Last-Modified", Long.valueOf(modified));
            response.setHeader("ETags", keywords.length + "");

            if(!oldEtag.equals(eTag)) {
                //拼装结果
                for(String tempWord : keywords) {
                    if(!StringUtils.isEmpty(tempWord)){
                        //分词之间以换行符连接
                        if(StringUtils.isNotEmpty(sb.toString())) {
                            sb.append("\r\n");
                        }
                        sb.append(tempWord);
                    }
                }
                //result = new String(result.getBytes("ISO8859-1"), "UTF-8");
                result = sb.toString();
                //更新时间
                response.setDateHeader("Last-Modified", System.currentTimeMillis());
            }

        }catch (Exception e){
            e.printStackTrace();
        }finally {
            System.out.println(result);
            return result;
        }
    }


然后这个词库就可以用啦!
