一文带你读懂MyBatis中的参数

public Object convertArgsToSqlCommandParam(Object[] args) { final int paramCount = params.size(); if (args == null || paramCount == 0) { return null; } else if (!hasNamedParameters && paramCount == 1) { return args[params.keySet().iterator().next()]; } else { final Map<String, Object> param = new ParamMap<Object>(); int i = 0; for (Map.Entry<Integer, String> entry : params.entrySet()) { param.put(entry.getValue(), args[entry.getKey()]); // issue #71, add param names as param1, param2...but ensure backward compatibility final String genericParamName = "param" + String.valueOf(i + 1); if (!param.containsKey(genericParamName)) { param.put(genericParamName, args[entry.getKey()]); } i++; } return param; }}
