常常用于数据库字段转为java字段
private static String changeColumn(String column) { String name = column; if (name.indexOf("_") > 0 && name.length() != name.indexOf("_") + 1) { int lengthPlace = name.indexOf("_"); name = name.replaceFirst("_", ""); String s = name.substring(lengthPlace, lengthPlace + 1); s = s.toUpperCase(); column = name.substring(0, lengthPlace) + s + name.substring(lengthPlace + 1); } else { return column; } return changeColumn(column); }
