這篇文章帶給大家的內容是關於Redis的事務操作的命令與執行操作（程式碼），有一定的參考價值，有需要的朋友可以參考一下，希望對你有幫助。
本文主要研究redis的事務操作
127.0.0.1:6379> multi OK 127.0.0.1:6379> incr total QUEUED 127.0.0.1:6379> incr len QUEUED 127.0.0.1:6379> exec 1) (integer) 2 2) (integer) 2 127.0.0.1:6379> get total "2" 127.0.0.1:6379> get len "2"
@Test
public void testMultiExec(){
RedisClient client = RedisClient.create("redis://192.168.99.100:6379/0");
StatefulRedisConnection<String, String> connection = client.connect();
RedisCommands<String, String> syncCommands = connection.sync();
syncCommands.set("hello","1");
syncCommands.set("world","2");
syncCommands.multi();
syncCommands.incr("hello");
syncCommands.incr("world");
//DefaultTransactionResult[wasRolledBack=false,result=[1, 2, 1, 3, 1]]
TransactionResult transactionResult = syncCommands.exec();
System.out.println(transactionResult);
System.out.println(syncCommands.get("hello"));
System.out.println(syncCommands.get("world"));

@Test
public void testMultiDiscard(){
RedisClient client = RedisClient.create("redis://192.168.99.100:6379/0");
StatefulRedisConnection<String, String> connection = client.connect();
RedisCommands<String, String> syncCommands = connection.sync();

syncCommands.incr("key1");
//需要有multi才可以执行discard，成功返回OK
String result = syncCommands.discard();
System.out.println(result);
System.out.println(syncCommands.get("key1"));
} @Test
public void testWatch(){
RedisClient client = RedisClient.create("redis://192.168.99.100:6379/0");
StatefulRedisConnection<String, String> connection = client.connect();
RedisCommands<String, String> syncCommands = connection.sync();
String key = "key";
syncCommands.watch(key);
//another connection
StatefulRedisConnection<String, String> conn2 = client.connect();
RedisCommands<String, String> syncCommands2 = conn2.sync();
syncCommands2.set(key, "a");
syncCommands.multi();
syncCommands.append(key, "b");
//DefaultTransactionResult [wasRolledBack=true, responses=0]
TransactionResult transactionResult = syncCommands.exec();
System.out.println(transactionResult);
System.out.println(syncCommands.get(key));
