springmvc架构工具类引用service为null的解决办法

1.由于LogInfoUtil类没有受注入扫描，就算给 dictService加注解，也不能解决；

2.由于dao层是接口，不能new，所以不能实例化点调；

实例代码如下：

package com.pns.util;import java.util.HashMap;import java.util.Map;import javax.servlet.ServletContext;import javax.servlet.http.HttpServletRequest;import org.springframework.web.context.support.WebApplicationContextUtils;import org.springframework.web.context.support.XmlWebApplicationContext;import com.pns.service.dict.DictService;

public class LogInfoUtil {private DictService dictService;public void CreatLogInfo(HttpServletRequest request,String sendrec_flg,String class_path,String method_name,String flag,String data_org,String data_input){Map<String,Object> map = new HashMap<String,Object>();map.put("sendrec_flg", sendrec_flg==null?"":sendrec_flg);map.put("class_path", class_path==null?"":class_path);map.put("method_name", method_name==null?"":method_name);map.put("flag", flag==null?"":flag);map.put("data_org", data_org==null?"":data_org);map.put("data_input", data_input==null?"":data_input);ServletContext sc = request.getSession().getServletContext();XmlWebApplicationContext cxt = (XmlWebApplicationContext)WebApplicationContextUtils.getWebApplicationContext(sc);if(cxt != null && cxt.getBean("dictService") != null && dictService == null){dictService = (DictService) cxt.getBean("dictService");}dictService.insertLogInfo(map);}}
