Java動態拼接字符串(MessageFormat)

使用MessageFormat動態拼接字符串舉例

源碼：

String p = "測試：{0}，{1}，{2}";
String r = MessageFormat.format(p, "11", "22", "33");

String p2 = "'{'\"prepareTypeCode\":\"commonStock\",\"skc\":\"{0}\",\"type\":\"skc\"'}'";
String r2 = MessageFormat.format(p2, "shoes123");


String p3 = "SELECT {0} from dms_order a JOIN dms_order_size  b ON a.id=b.order_id where a.skc = ''{1}''";
String r3 = MessageFormat.format(p3, "id", "shoes123");

運行結果：

測試：11，22，33
{"prepareTypeCode":"commonStock","skc":"shoes123","type":"skc"}
SELECT id from dms_order a JOIN dms_order_size  b ON a.id=b.order_id where a.skc = 'shoes123'
