Java如何调用其他服务器接口

在applicationContext.xml配置：

<!-- 通讯录配置-->
<bean id="contactService" class="cn.com.qytx.ydzj.impl.ContactImpl">
<!--短信通统计URL-->
<constructor-arg value="http://10.200.17.221:8080/txzl/report/SMS_getSMSReport.action"/>
<!--语音通知统计URL-->
<constructor-arg value="http://10.200.17.221:8080/txzl/report/notice_getNoticeReport.action"/>
<!--语音通知列表URL-->
<constructor-arg value="http://10.200.17.221:8080/txzl/report/notice_findNoticePageByUserId.action"/>
<!--电话会议统计URL-->
<constructor-arg value="http://10.200.17.221:8080/txzl/report/meeting_getMeetingReport.action"/>
<!--电话会议列表URL-->
<constructor-arg value="http://10.200.17.221:8080/txzl/report/meeting_findMeetingPageByUserId.action"/>
</bean>

在类中引用ContactImpl.java

<pre class="java" name="code">package cn.com.qytx.ydzj.impl;

}

然后传送对象json格式

/**  *  * 功能：电话会议统计报表  */ public void getMeetingReport(){  try{   String startTime="";   String endTime="";   if(StringUtils.isNotBlank(reportTime)){    String[] arrs=reportTime.split("-");    if(arrs.length>1){     Integer year=Integer.parseInt(arrs[0]);     Integer month=Integer.parseInt(arrs[1]);     Integer day=30;     if(month==1||month==3||month==5||month==7||month==8||month==10||month==12){      day=31;     }     if((year%4==0&&year%100!=0)||(year%400==0)){      if(month==2){       day=29;      }     }else{      if(month==2){       day=28;      }     }     startTime=reportTime+"-01 00:00:00";     endTime=reportTime+"-"+day+" 23:59:59";    }   }      Map<String,Object> map=reportService.getMeetingReport(token, startTime,endTime);   Gson gson=new Gson();   String json=gson.toJson(map);   ajax(json);  }catch(NoticeException ne){   try {    ajax(ne.getMessage());   } catch (Exception e) {    e.printStackTrace();   }  }catch(Exception e){   e.printStackTrace();  } }

完毕!
