请把for (String taskId : taskIdSet) {这后面的部分打印出来

好的，以下是修改后的代码，增加了打印语句： private static void insertData(Connection conn, int threadNo) throws SQLException { PreparedStatement ps = conn.prepareStatement("INSERT INTO " + TABLE_NAME + " VALUES(?, ?, ?, ?, ?)"); Set taskIdSet = new HashSet<>(); while(taskIdSet.size() < 100000){ StringBuilder sb = new StringBuilder(TASK_ID_PREFIX); for(int i=0; i<24; i++){ if(i == 21){ // 跳过原序列号位置 continue; } int randomNum = (int)(Math.random() * 16); char hexChar = Character.forDigit(randomNum, 16); sb.setCharAt(i, hexChar); } taskIdSet.add(sb.toString()); } for (String taskId : taskIdSet) { int taskState; if (threadNo % 10 < 2) taskState = 1; // 10%的数据taskState为1 else if (threadNo % 10 < 4) taskState = 3; // 20%的数据taskState为3 else if (threadNo % 10 < 6) taskState = 5; // 30%的数据taskState为5 else if (threadNo % 10 < 8) taskState = 7; // 20%的数据taskState为7 else taskState = 9; // 20%的数据taskState为9 ps.setString(1, taskId); ps.setString(2, TRANS_NO); ps.setString(3, BANK_NO); ps.setString(4, SYSTEM_NO); ps.setInt(5, taskState); ps.addBatch(); System.out.println("Thread " + threadNo + ": Inserted taskId " + taskId + " with taskState " + taskState); } ps.executeBatch(); ps.close(); }
