beansdb4jbeansdb的java客户端

这是beansdb的java客户端, 它使用了和python客户端一模一样的hash算法， 所以它和python客户端是完全兼容 — 这意味着你可以用python客户端存一个东西进beansdb， 然后用java客户端把它取出来。

示例代码：

 // specify the beansdb nodes.
 Map<InetSocketAddress, Range> servers = new HashMap<InetSocketAddress, Range>();
 servers.put(new InetSocketAddress("localhost", 7900), new Range(, 16));
 servers.put(new InetSocketAddress("localhost", 7901), new Range(, 16));
 servers.put(new InetSocketAddress("localhost", 7902), new Range(, 16));
  
 // 3,2,2 is the NRW number in the Dynamo thesis
 Beansdb db = new Beansdb(servers, 16, 3, 2, 2);
  
 // set the key: foo to value: bar
 db.set("foo", "bar");
  
 // get the value of foo
 System.out.println(db.get("foo"));
  
 // get the value for keys: hello, james, foo
 List<String> keys = new ArrayList<String>(3);
 keys.add("hello");
 keys.add("james");
 keys.add("foo");
 Map<String, Object> ret = db.getMulti(keys);
  
 for (String key : ret.keySet()) {
        System.out.println(key + " : " + ret.get(key));
 }
  
 // delete the key: foo
 db.delete("foo");
  
 // close the db connection
 db.close();
