[一]、概述

java实现了对ttserver服务端的连接和访问。相关的源代码和jar包可以到其官网下载。

官网地址：http://code.google.com/p/tokyotyrant-java/

[二]、演示

1.RDB ：官方Tokyo Tyrant API的实现

演示代码：RDBExample.java

1	package com.micmiu.nosql.ttserver;

2

3	import java.io.IOException;

4	import java.net.InetSocketAddress;

5

6	import tokyotyrant.RDB;

7	import tokyotyrant.transcoder.DoubleTranscoder;

8	import tokyotyrant.transcoder.IntegerTranscoder;

17	public class RDBExample {

18

19	public static void main(String[] args) throws IOException {

20

21	RDB db = new RDB();

22

try {

23	// connect to the server

24	// db.open(new NodeAddress("tcp://192.168.126.134:1978"));

25	db.open(new InetSocketAddress("192.168.126.134", 1978));

26

27	Object key;

28	Object value;

29	// store records

30	if (db.put("my_firstname", "Sun")) {

31	System.out.println("db put my_firstname successful.");

32

} else {

33	System.out.println("db put my_firstname error.");

34

}

35

36	if (db.put("my_lastname", "Michael")) {

37	System.out.println("db put my_lastname successful.");

38

} else {

39	System.out.println("db put my_lastname error.");

40

}

41

42	if (db.put("my_blogurl", "www.micmiu.com")) {

43	System.out.println("db put my_blogurl successful.");

44

} else {

45	System.out.println("db put my_blogurl error.");

46

}

47

48	if (db.put("my_weibo", "www.sina.com/ctosun")) {

49	System.out.println("db put my_weibo successful.");

50

} else {

51	System.out.println("db put my_weibo error.");

52

}

53

54	// retrieve records

55	value = db.get("my_blogurl");

56	System.out.println("test_blogurl =: " + value);

57

58	value = db.get("test_noexit");

59	System.out.println("test_noexit =: " + value);

60

61	System.out.println("===== test repeat put ");

62	db.put("test_desc", "hello world");

63	System.out.println("test_desc =: " + db.get("test_desc"));

64	db.put("test_desc", "repeat put value is hello Michael");

65	System.out.println("test_desc =: " + db.get("test_desc"));

66

67	// Initialize the iterator

68	System.out.println("===== access all key ");

69	db.iterinit();

70	while ((key = db.iternext()) != null) {

71	value = db.get(key);

72	System.out.println(key + " =: " + value);

73

}

74	System.out.println("===== test int double ");

75	// add int

76	db.put("int_i", 3, new IntegerTranscoder());

77	int i = db.addint("int_i", 4);

78	System.out.println(" i =: " + i);

79	System.out.println("int_i =: "

80	+ db.get("int_i", new IntegerTranscoder()));

81

82	// add double

83	db.put("dou_d", 3.0D, new DoubleTranscoder());

84	double d = db.adddouble("dou_d", 4.0D);

85	System.out.println(" d =: " + d);

86	System.out.println("dou_d =: "

87	+ db.get("dou_d", new DoubleTranscoder()));

88

89	} catch (Exception e) {

90	e.printStackTrace();

91	} finally {

92	// close the connection

93	db.close();

94

}

95

}

96

}

运行日志如下：

db put my_firstname successful.
db put my_lastname successful.
db put my_blogurl successful.
db put my_weibo successful.
test_blogurl =: www.micmiu.com
test_noexit =: null
===== test repeat put
test_desc =: hello world
test_desc =: repeat put value is hello Michael
===== access all key
my_firstname =: Sun
my_lastname =: Michael
my_blogurl =: www.micmiu.com
my_weibo =: www.sina.com/ctosun
test_desc =: repeat put value is hello Michael
===== test int double
 i =: 7
int_i =: 7
 d =: 7.0
dou_d =: 7.0

2.MRDB ：用于多数据源，可复制、可靠性高、响应快等特点

4	import tokyotyrant.networking.NodeAddress;

19	public static void main(String[] args) throws Exception {

21	MRDB db = null;

22

try {

23	db = new MRDB();

24	// connect to the server

25	db.open(NodeAddress.addresses("tcp://192.168.126.134:1978"));

26	Object value;

27	// store records

28	if (db.await(db.put("my_firstname", "Sun"))) {

29	System.out.println("MRDB put my_firstname successful.");

30

} else {

31	System.out.println("MRDB put my_firstname error.");

32

}

33

34	if (db.await(db.put("my_lastname", "Michael"))) {

35	System.out.println("MRDB put my_lastname successful.");

45

46	if (db.await(db.put("my_weibo", "www.sina.com/ctosun"))) {

47	System.out.println("MRDB put my_weibo successful.");

48

} else {

49	System.out.println("MRDB put my_weibo error.");

50

}

51

52	// retrieve records

53	value = db.await(db.get("my_blogurl"));

54	System.out.println("test_blogurl =: " + value);

55

56	value = db.await(db.get("test_noexit"));

57	System.out.println("test_noexit =: " + value);

58

59	System.out.println("===== test repeat put ");

60	db.put("test_desc", "hello world");

61	System.out.println("test_desc =: " + db.await(db.get("test_desc")));

62	db.put("test_desc", "repeat put value is hello Michael");

63	System.out.println("test_desc =: " + db.await(db.get("test_desc")));

64

65	// add int

66	db.put("int_i", 4);

67	// add double

68	db.put("dou_d", 8.8D);

69

70	// Initialize the iterator

71	System.out.println("===== access all key ");

72	Object[] keys = db

73	.await(db.fwmkeys("", db.size().get().intValue()));

74	for (Object keyObj : keys) {

75	System.out.println(keyObj + " =: " + db.await(db.get(keyObj)));

76

}

77

78	} catch (Exception e) {

79	e.printStackTrace();

80	} finally {

81	// close the connection

82	db.close();

83

}

84

}

85

}
