前臺js建立圖形

var option1={
    	        title : {
    	          text: '學歷統計',
    	          x:'center',
    	          y:'center'
    	        },
    	        series: [{
    	          type: 'pie',
    	          clockwise:false,
    	          radius:['45%','75%'],
    	          label: {
    	            normal: {
    	              show: true,
    	              formatter: '{b}，{c}',
    	              rich: {}
    	            }
    	          }
    	        }],
    	        color:['#27AAE1','#0071BC','#83B15A','#FBB040','#BE1E2D','#C6E579','#fad797'],
    	        textStyle:{
    	          color:'#333',
    	          fontSize:16
    	        }
    	      }
    	  chart1.setOption(option1);
    	  var unitId=document.getElementById("selectUnit").value;
        //非同步載入資料
        $.ajax({
        	url:path+"/unitConditionController/getDegreeData.do?unitId="+unitId,
        	type:'post',
        	dataType:'json',
        	async:false,
        	success:function(data){
                chart1.setOption({
                    series:[{
                      data:data,//接受後臺返回的資料，需要注意資料型別
                    }]
                  });
        	},
        	error:function(){
        		
        	}
        })
 

controller層：

/**
	 * 獲取學歷資訊
	 * @param unitId
	 * @return
	 */
	@RequestMapping(value="/getDegreeData", method = { RequestMethod.POST })
	@ResponseBody
	public List<Map<String, Object>> getDegreeData(@RequestParam("unitId") String unitId){
		    List<Map<String,Object>> list=new ArrayList<Map<String,Object>>();
			Map<String,Object> map1=new HashMap<String,Object>();
			map1.put("unitId",unitId);
			List<PersonBaseInfoDTO> personBaseInfoDTOs=personBaseInfoService.searchListByCondition(map1);
			list=unitConditionService.getDegreeList(personBaseInfoDTOs);
	        return list;
		}
 

serviceImpl

資料存在一個map型別的list集合中,返回json資料，加@ResponseBody註解

 /**
     * 獲取學歷資訊
     */
	@Override
	public List<Map<String, Object>> getDegreeList(List<PersonBaseInfoDTO> personBaseInfoDTOs) {
		List<Map<String,Object>> list=new ArrayList<Map<String,Object>>();
		int twen=0;
		int btt=0;
		int btf=0;
		int bff=0;
		int bfs=0;
		int os=0;
		int k=0;
		for(PersonBaseInfoDTO pDTO:personBaseInfoDTOs){				
			if(pDTO.getDegreeStatus()!=null){
				String degree=pDTO.getDegreeStatus();
				if(degree.equals("研究生")){
					twen++;
				}else if (degree.equals("碩士")) {
					btt++;
				}else if (degree.equals("本科")) {
					btf++;
				}else if (degree.equals("自考本科")) {

				}else if (degree.equals("大專")) {
					bfs++;
			    }else if(degree.equals("博士")){

			}								
	 }
