Map params = new HashMap<>(); params.put( "a" , "safd" ); params.put( "b" , "dsjaf" ); params.put( "c" , "123456" ); params.put( "d" , "风景的撒娇房顶上经费等快速拉进房间空间上" ); String[] keys = new String[params.size()]; Set sset = params.keySet(); int i = 0 ; for (String os : sset) { keys[i++] = os; } Map map = new HashMap<>(); map.put( "tablename" , "pay_o_tb" ); map.put( "keys" , keys); map.put( "params" , params); mapper.creatTableAndInsert(map);
