1.這是反射過程 @Override protected String createTable(String tableName,Class bean) { Field[] fields= bean.getDeclaredFields(); StringBuilder stringBuilder =new StringBuilder(); stringBuilder.append("create table if not exists "+tableName+" ( "); for (int i = 0; i <fields.length ; i++) { TLog.error(fields[i].getName()); if (i==fields.length-1){ stringBuilder.append(" "+fields[i].getName()+" varchar(40)"); }else { stringBuilder.append(" "+fields[i].getName()+" varchar(40),"); } } stringBuilder.append(" );"); return stringBuilder.toString(); } 2.這是反射的bean對象 public class City { public City(String id, String name, String cityCode) { this.id = id; this.name = name; this.cityCode = cityCode; } public String id; public String name; public String cityCode; } 3.這是log日志 01-11 10:16:17.467 5631-5631/com.ccj.archdesigns E/TLog: cityCode 01-11 10:16:17.467 5631-5631/com.ccj.archdesigns E/TLog: id 01-11 10:16:17.467 5631-5631/com.ccj.archdesigns E/TLog: name 01-11 10:16:17.467 5631-5631/com.ccj.archdesigns E/TLog: $change 01-11 10:16:17.467 5631-5631/com.ccj.archdesigns E/TLog: serialVersionUID
