Java架构之Redis系列：通过文章点赞排名案例学习Sortedset命令

下面是java代码

@Test 
 
public void zUnionStore() { 
 
zSetOperations.add("zUnionStoreKey1", "one", 1); 
 
zSetOperations.add("zUnionStoreKey1", "two", 2); 
 
zSetOperations.add("zUnionStoreKey2", "one", 1); 
 
zSetOperations.add("zUnionStoreKey2", "two", 2); 
 
zSetOperations.add("zUnionStoreKey2", "three", 3); 
 
ZParams zParams = new ZParams(); 
 
zParams.weightsByDouble(2, 3); 
 
zParams.aggregate(ZParams.Aggregate.SUM); 
 
jedis.zunionstore("zUnionStoreSumResult", zParams, "zUnionStoreKey1", "zUnionStoreKey2"); 
 
//求最小值 
 
zParams.aggregate(ZParams.Aggregate.MIN); 
 
jedis.zunionstore("zUnionStoreMinResult", zParams, "zUnionStoreKey1", "zUnionStoreKey2"); 
 
//求最大值 
 
zParams.aggregate(ZParams.Aggregate.MAX); 
 
jedis.zunionstore("zUnionStoreMaxResult", zParams, "zUnionStoreKey1", "zUnionStoreKey2"); 
 
//spring 
 
zSetOperations.unionAndStore("zUnionStoreKey1", "zUnionStoreKey2", "zUnionStoreResult"); 
 
printTuple("zUnionStoreSumResult", jedis.zrangeWithScores("zUnionStoreSumResult", 0, -1)); 
 
printTuple("zUnionStoreMinResult", jedis.zrangeWithScores("zUnionStoreMinResult", 0, -1)); 
 
printTuple("zUnionStoreMaxResult", jedis.zrangeWithScores("zUnionStoreMaxResult", 0, -1)); 
 
printTuple("zUnionStoreResult", jedis.zrangeWithScores("zUnionStoreResult", 0, -1)); 
 
}
