Spring mvc parameter complex mixed transfer method, mixed return method:
When passing the entity of the list, if you also pass other single attributes, these single attributes should be placed in the requestHeader,
Similar image streams are placed in the requestbody (generally httpclient tool side), and the background is also taken from the requestbody
@RequestMapping(value="/system/opmRole/Auths")
@ResponseBody
public JSONArray treeRead(@RequestHeader(value="fg") String fg,@RequestHeader(value="id",required=false) String id,@RequestHeader(value="leave") String leave,
@RequestHeader(value="roleId") String roleId,@RequestHeader(value="pId") String pId,@RequestHeader(value="groupId",required=false) String groupId1,
@RequestBody(required=false) List<OpmRolelimit> o){
JsonArray.addAll(treeRead(fg,id,leave,roleId,p.get("ID")+"",groupId,o));
return JsonArray;

Ajax can either use responsebody (automatically converted to json), or use response.getWrite().write() (can be string or html (the whole html part of the page is difficult to splicing))
You can also directly return "string", or page jump
js to be able to call back to the need to write the receiving format
=====================================================================================================
response.getWrite().write() (character) return and return (page jump, character) can be mixed in one method
