整合代码已经过测试
1、pom
1 <!-- redisson --> 2 <dependency> 3 <groupId>org.redisson</groupId> 4 <artifactId>redisson</artifactId> 5 <version>3.5.7</version> 6 </dependency>
2、properties
# redis spring.redis.host= spring.redis.port= spring.redis.password= spring.redis.jedis.pool.max-active=500 spring.redis.jedis.pool.max-idle=1000 spring.redis.jedis.pool.max-wait=6000ms spring.redis.jedis.pool.min-idle=4
3、添加redisson配置类、这里是单机模式
1 package com.example.common.config;
2
3 import org.redisson.Redisson;
4 import org.redisson.api.RedissonClient;
5 import org.redisson.config.Config;
6 import org.springframework.beans.factory.annotation.Value;
7 import org.springframework.context.annotation.Bean;
8 import org.springframework.context.annotation.Configuration;
9
10 /**
11 * redisson 配置类
12 * Created on 2018/6/19
13 */
14 @Configuration
15 public class RedissonConfig {
16
17 @Value("${spring.redis.host}")
18 private String host;
19
20 @Value("${spring.redis.port}")
21 private String port;
22
23 @Value("${spring.redis.password}")
24 private String password;
25
26 @Bean
27 public RedissonClient getRedisson(){
28
29 Config config = new Config();
30 config.useSingleServer().setAddress("redis://" + host + ":" + port).setPassword(password);
31 //添加主从配置
32 // config.useMasterSlaveServers().setMasterAddress("").setPassword("").addSlaveAddress(new String[]{"",""});
33
34 return Redisson.create(config);
35 }
36
37 }
4、加入redisson 操作类（redissonService）
1 package com.example.common.base;
2
3 import org.redisson.api.*;
4 import org.redisson.config.Config;
5 import org.springframework.beans.factory.annotation.Autowired;
6 import org.springframework.stereotype.Service;
7
8 import java.io.IOException;
9
10 /**
11 * redisson操作类
12 */
13 @Service("redissonService")
14 public class RedissonService {
15
16 @Autowired
17 private RedissonClient redissonClient;
18
19 public void getRedissonClient() throws IOException {
20 Config config = redissonClient.getConfig();
21 System.out.println(config.toJSON().toString());
22 }
23
24 /**`
25 * 获取字符串对象
26 *
27 * @param objectName
28 * @return
29 */
30 public <T> RBucket<T> getRBucket(String objectName) {
31 RBucket<T> bucket = redissonClient.getBucket(objectName);
32 return bucket;
33 }
34
35 /**
36 * 获取Map对象
37 *
38 * @param objectName
39 * @return
40 */
41 public <K, V> RMap<K, V> getRMap(String objectName) {
42 RMap<K, V> map = redissonClient.getMap(objectName);
43 return map;
44 }
45
46 /**
47 * 获取有序集合
48 *
49 * @param objectName
50 * @return
51 */
52 public <V> RSortedSet<V> getRSortedSet(String objectName) {
53 RSortedSet<V> sortedSet = redissonClient.getSortedSet(objectName);
54 return sortedSet;
55 }
56
57 /**
58 * 获取集合
59 *
60 * @param objectName
61 * @return
62 */
63 public <V> RSet<V> getRSet(String objectName) {
64 RSet<V> rSet = redissonClient.getSet(objectName);
65 return rSet;
66 }
67
68 /**
69 * 获取列表
70 *
71 * @param objectName
72 * @return
73 */
74 public <V> RList<V> getRList(String objectName) {
75 RList<V> rList = redissonClient.getList(objectName);
76 return rList;
77 }
78
79 /**
80 * 获取队列
81 *
82 * @param objectName
83 * @return
84 */
85 public <V> RQueue<V> getRQueue(String objectName) {
86 RQueue<V> rQueue = redissonClient.getQueue(objectName);
87 return rQueue;
88 }
89
90 /**
91 * 获取双端队列
92 *
93 * @param objectName
94 * @return
95 */
96 public <V> RDeque<V> getRDeque(String objectName) {
97 RDeque<V> rDeque = redissonClient.getDeque(objectName);
98 return rDeque;
99 }
100
101
102 /**
103 * 获取锁
104 *
105 * @param objectName
106 * @return
107 */
108 public RLock getRLock(String objectName) {
109 RLock rLock = redissonClient.getLock(objectName);
110 return rLock;
111 }
112
113 /**
114 * 获取读取锁
115 *
116 * @param objectName
117 * @return
118 */
119 public RReadWriteLock getRWLock(String objectName) {
120 RReadWriteLock rwlock = redissonClient.getReadWriteLock(objectName);
121 return rwlock;
122 }
123
124 /**
125 * 获取原子数
126 *
127 * @param objectName
128 * @return
129 */
130 public RAtomicLong getRAtomicLong(String objectName) {
131 RAtomicLong rAtomicLong = redissonClient.getAtomicLong(objectName);
132 return rAtomicLong;
133 }
134
135 /**
136 * 获取记数锁
137 *
138 * @param objectName
139 * @return
140 */
141 public RCountDownLatch getRCountDownLatch(String objectName) {
142 RCountDownLatch rCountDownLatch = redissonClient.getCountDownLatch(objectName);
143 return rCountDownLatch;
144 }
145
146 /**
147 * 获取消息的Topic
148 *
149 * @param objectName
150 * @return
151 */
152 public <M> RTopic<M> getRTopic(String objectName) {
153 RTopic<M> rTopic = redissonClient.getTopic(objectName);
154 return rTopic;
155 }
156 }
5.、测试代码
package com.example.test;
import com.example.common.base.RedissonService;
import org.redisson.api.RLock;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import java.util.concurrent.TimeUnit;
@Controller
@RequestMapping("test")
public class TestService {
private static final Logger log = LoggerFactory.getLogger(TestService.class);
@Autowired
private RedissonService redissonService;
@RequestMapping(value = "/test")
@ResponseBody
public void test(String recordId) {
RLock lock = redissonService.getRLock(recordId);
try {
boolean bs = lock.tryLock(5, 6, TimeUnit.SECONDS);
if (bs) {
// 业务代码
log.info("进入业务代码: " + recordId);
lock.unlock();
} else {
Thread.sleep(300);
}
} catch (Exception e) {
log.error("", e);
lock.unlock();
}
}
}
