1、工具類

public class Datas {
	private List<Integer> ids = new ArrayList<Integer>();

	public List<Integer> getIds() { 
		return ids;
	}

	public void setIds(List<Integer> ids) {
		this.ids = ids;
	}
}

前臺：

$("#assignBtn").click(function(){
          console.log(roleId);    		
          var json ={roleId:roleId};
　　　　　　var treeObj = $.fn.zTree.getZTreeObj("treeDemo");
          var nodes = treeObj.getCheckedNodes(true);
          console.log("nodes={}",nodes);
          $.each(nodes,function(i,e){
          	var permissionId = e.id;
          	console.log(permissionId);
          	json['ids['+i+']
 
'] = permissionId;
          });
          		
          $.ajax({
          	type:"post",
          	url:"${PATH}/role/doAssignPermissionToRole",
          	data:json,
          	success:function(result){
          	　　if("ok" == result){
          		layer.msg("分配成功",{icon:6,time:1000},function(){
          			$("#assignModal").modal('hide');
          		});
          	　　}else{
          		layer.msg("分配失敗",{incon:5,time:1000});
          	　　}
          	}			
       });    		
});

　後臺：

@ResponseBody
@RequestMapping("/role/doAssignPermissionToRole")
public String doAssignPermissionToRole(Integer roleId,Datas ds) {
　　　　log.debug("roleId={}",roleId);
　　　　log.debug("permissionId={}",ds.getIds());
		
　　　　rolerService.saveRoleAndPermissionRelationship(roleId,ds.getIds());
　　　　return "ok";
}
