六、封装一个操作hash基本数据类型的工具类
1 package com.xbq.demo.util;
2
3 import javax.annotation.Resource;
4 import org.springframework.data.redis.core.StringRedisTemplate;
5 import org.springframework.stereotype.Component;
6
7 /**
8 * 操作 hash 的基本操作
9 * @author xbq
10 */
11 @Component("redisCache")
12 public class RedisCacheUtil {
13
14 @Resource
15 private StringRedisTemplate redisTemplate;
16
17 /**
18 * 向Hash中添加值
19 * @param key 可以对应数据库中的表名
20 * @param field 可以对应数据库表中的唯一索引
21 * @param value 存入redis中的值
22 */
23 public void hset(String key, String field, String value) {
24 if(key == null || "".equals(key)){
25 return ;
26 }
27 redisTemplate.opsForHash().put(key, field, value);
28 }
29
30 /**
31 * 从redis中取出值
32 * @param key
33 * @param field
34 * @return
35 */
36 public String hget(String key, String field){
37 if(key == null || "".equals(key)){
38 return null;
39 }
40 return (String) redisTemplate.opsForHash().get(key, field);
41 }
42
43 /**
44 * 判断 是否存在 key 以及 hash key
45 * @param key
46 * @param field
47 * @return
48 */
49 public boolean hexists(String key, String field){
50 if(key == null || "".equals(key)){
51 return false;
52 }
53 return redisTemplate.opsForHash().hasKey(key, field);
54 }
55
56 /**
57 * 查询 key中对应多少条数据
58 * @param key
59 * @return
60 */
61 public long hsize(String key) {
62 if(key == null || "".equals(key)){
63 return 0L;
64 }
65 return redisTemplate.opsForHash().size(key);
66 }
67
68 /**
69 * 删除
70 * @param key
71 * @param field
72 */
73 public void hdel(String key, String field) {
74 if(key == null || "".equals(key)){
75 return;
76 }
77 redisTemplate.opsForHash().delete(key, field);
78 }
79 }
七、测试类
1 package com.xbq.demo;
2
3 import org.junit.Before;
4 import org.junit.Test;
5 import org.springframework.context.support.ClassPathXmlApplicationContext;
6 import com.xbq.demo.util.RedisCacheUtil;
7
8 /**
9 * 测试
10 */
11 public class RedisTest {
12
13 private RedisCacheUtil redisCache;
14 private static String key;
15 private static String field;
16 private static String value;
17
18 @Before
19 public void setUp() throws Exception {
20 ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");
21 context.start();
22 redisCache = (RedisCacheUtil) context.getBean("redisCache");
23 }
24
25 // 初始化 数据
26 static {
27 key = "tb_student";
28 field = "stu_name";
29 value = "一系列的关于student的信息！";
30 }
31
32 // 测试增加数据
33 @Test
34 public void testHset() {
35 redisCache.hset(key, field, value);
36 System.out.println("数据保存成功！");
37 }
38
39 // 测试查询数据
40 @Test
41 public void testHget(){
42 String re = redisCache.hget(key, field);
43 System.out.println("得到的数据：" + re);
44 }
45
46 // 测试数据的数量
47 @Test
48 public void testHsize(){
49 long size = redisCache.hsize(key);
50 System.out.println("数量为：" + size);
51 }
52 }
八、控制层 StudentController
1 package com.xbq.demo.controller;
2
3 import java.io.PrintWriter;
4 import javax.annotation.Resource;
5 import javax.servlet.http.HttpServletRequest;
6 import javax.servlet.http.HttpServletResponse;
7 import org.springframework.stereotype.Controller;
8 import org.springframework.web.bind.annotation.RequestMapping;
9 import com.xbq.demo.util.RedisCacheUtil;
10
11 /**
12 * 控制层
13 * @author xbq
14 */
15 @Controller
16 @RequestMapping("/student/")
17 public class StudentController {
18
19 @Resource
20 private RedisCacheUtil redisCache;
21
22 // 查询数据
23 @RequestMapping("list")
24 public String list(HttpServletResponse response, HttpServletRequest request){
25 String re = redisCache.hget("tb_student", "stu_id");
26 try {
27 this.write(response, re);
28 } catch (Exception e) {
29 e.printStackTrace();
30 }
31 return null;
32 }
33
34 /**
35 * 回写到页面上
36 * @param response
37 * @param o
38 * @throws Exception
39 */
40 private void write(HttpServletResponse response, Object o) throws Exception{
41 response.setContentType("text/html;charset=utf-8");
42 PrintWriter out=response.getWriter();
43 out.println(o.toString());
44 out.flush();
45 out.close();
46 }
47 }
九、jsp页面
<body>
Hello World!
<a href="${pageContext.request.contextPath}/student/list.do">显示数据</a>
</body>
