记录一个集合比较器------＞

利用集合的比较器
把List集合 重新整理成新List

List<Map<String,Object>>  listSchoolMap=new ArrayList<>();

try {
     
	List<HashMap<String, Object>> schoolList = schoolService.getSchoolList();
	listSchoolMap = schoolList.stream().map(e -> {
     
		Map<String, Object> paramMap = new HashMap<String, Object>();// 参数集
		paramMap.put("id", (Integer) e.get("schoolId"));
		paramMap.put("text", (String) e.get("schoolName"));
		return paramMap;
	}).collect(Collectors.toList());
} catch (Exception e) {
     
	// TODO: handle exception
	e.printStackTrace();
}
return listSchoolMap;
