action处理如下
public void getNodeData() {
List<Map<String, Object>> nodedata = service.getNodes(this.getId());
List<Map<String, Object>> list = new ArrayList<Map<String, Object>>();
Map<String, Object> tmp = null;
for (Map<String, Object> map : nodedata) {
tmp = new HashMap<String, Object>();
tmp.put("id", map.get("id"));
tmp.put("name", map.get("name"));
tmp.put("isParent",
Integer.valueOf(map.get("cnt").toString()) > 0 ? true
: false);
list.add(tmp);
}
try {
PrintWriter out;
JSONObject jo = new JSONObject();
response.setCharacterEncoding("gbk");
response.setContentType("text/html; charset=GBK");
out = response.getWriter();
System.out.println(JSONArray.fromObject(list).toString());
out.print(JSONArray.fromObject(list).toString());
out.close();
} catch (IOException e) {
e.printStackTrace();
}
}
Service处理如下
public List<Map<String, Object>> getNodes(String id) {
return dao.getNodes(id);
}
Dao处理如下
public List<Map<String, Object>> getNodes(String id) {
List<String> params = new ArrayList<String>();
StringBuffer querySQL = new StringBuffer();
querySQL.append("SELECT tt.wsystemcode id,tt.wsystemname name");
querySQL.append(",(SELECT COUNT (1) cnt FROM datacenter_v3.tcode.t_cod_wsystem t WHERE t.parentcode = tt.wsystemcode) cnt");
querySQL.append(" FROM datacenter_v3.tcode.t_cod_wsystem tt");
querySQL.append(" WHERE 1=1");
if(Tool.isNull(id)){
querySQL.append(" and tt.parentcode is null");
}else{
querySQL.append(" and tt.parentcode = ?");
params.add(id);
}
querySQL.append(" GROUP BY tt.wsystemcode,tt.wsystemname");
querySQL.append(" ORDER BY tt.wsystemcode");
return search(querySQL.toString(), params.toArray());
}
