Spring集成Redis方案（spring-data-redis）（基於Jedis的單機模式）（待實踐）
阿新 • • 發佈：2017-10-05
packaging 基於 .cn @override time Coding 很好 -o -i
繼上一篇文章http://www.cnblogs.com/EasonJim/p/7625738.html中提到的幾款客戶端，它們基本都能和Spring集成。
下面介紹的是基於Spring原生的spring-data-redis去集成。
還要註意的是，Spring整合了Jedis框架進去，所以下面配置上還會基於Jedis去實現的，但是Spring在上層已經集成了很好用的工具類。
而整個框架基於Spring Data，裏面集成了主流的應用，比如Redis，MongoDB等，而基於這些應用的一些非常好用的框架也集成了，比如Jedis這些。
我猜測，基於Spring Data Redis去集成的，底層還是用Jedis去實現，應該是可以實現客戶端集群的，下次我再實踐詳細分析一下。
Spring Data Redis
項目結構：
POM：
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.x.redis</groupId> <artifactId>Spring_redis</artifactId> <version>1.0-SNAPSHOT</version> <packaging>jar</packaging> <name>Spring_redis</name> <url>http://maven.apache.org</url> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> </properties> <dependencies> <dependency> <groupId>org.springframework.data</groupId> <artifactId>spring-data-redis</artifactId> <version>1.0.2.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>3.1.2.RELEASE</version> </dependency> <dependency> <groupId>redis.clients</groupId> <artifactId>jedis</artifactId> <version>2.1.0</version> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.8.2</version> <scope>test</scope> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>1.6.1</version> </dependency> <!-- 將現有的jakarta commons logging的調用轉換成lsf4j的調用。 --> <dependency> <groupId>org.slf4j</groupId> <artifactId>jcl-over-slf4j</artifactId> <version>1.6.1</version> </dependency> <!-- Hack：確保commons-logging的jar包不被引入，否則將和jcl-over-slf4j沖突 --> <dependency> <groupId>commons-logging</groupId> <artifactId>commons-logging</artifactId> <version>1.1.1</version> <scope>provided</scope> </dependency> <!-- slf4j的實現：logback，用來取代log4j。更快、更強！ --> <dependency> <groupId>ch.qos.logback</groupId> <artifactId>logback-classic</artifactId> <version>0.9.24</version> <scope>runtime</scope> </dependency> </dependencies> </project>
applicationContext.xml：
context:property-placeholder標簽用來導入properties文件。從而替換${redis.maxIdle}這樣的變量。
context:component-scan是為了在com.x.redis.dao報下的類能夠實用spring的註解註入的方式。
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context" xmlns:jee="http://www.springframework.org/schema/jee" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> <context:property-placeholder location="classpath:redis.properties" /> <context:component-scan base-package="com.x.redis.dao"> </context:component-scan> <bean id="poolConfig" class="redis.clients.jedis.JedisPoolConfig"> <property name="maxIdle" value="${redis.maxIdle}" /> <property name="maxActive" value="${redis.maxActive}" /> <property name="maxWait" value="${redis.maxWait}" /> <property name="testOnBorrow" value="${redis.testOnBorrow}" /> </bean> <bean id="connectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory" p:host-name="${redis.host}" p:port="${redis.port}" p:password="${redis.pass}" p:pool-config-ref="poolConfig"/> <bean id="redisTemplate" class="org.springframework.data.redis.core.StringRedisTemplate"> <property name="connectionFactory" ref="connectionFactory" /> </bean> <bean id="userDAO" class="com.x.redis.dao.impl.UserDAOImpl" /> </beans>
redis.properties：
# Redis settings
#redis.host=192.168.20.101
#redis.port=6380
#redis.pass=foobared
redis.host=127.0.0.1
redis.port=6379
redis.pass=
redis.maxIdle=300
redis.maxActive=600
redis.maxWait=1000
redis.testOnBorrow=true
UserDAOImpl：
Spring對DAO層的封裝很多用了類似於下面代碼的模板方式。
RedisTemplate就是Spring對Redis的一個封裝。
public class UserDAOImpl implements UserDAO { @Autowired protected RedisTemplate<Serializable, Serializable> redisTemplate; public void saveUser(final User user) { redisTemplate.execute(new RedisCallback<Object>() { @Override public Object doInRedis(RedisConnection connection) throws DataAccessException { connection.set(redisTemplate.getStringSerializer().serialize("user.uid." + user.getId()), redisTemplate.getStringSerializer().serialize(user.getName())); return null; } }); } @Override public User getUser(final long id) { return redisTemplate.execute(new RedisCallback<User>() { @Override public User doInRedis(RedisConnection connection) throws DataAccessException { byte[] key = redisTemplate.getStringSerializer().serialize("user.uid." + id); if (connection.exists(key)) { byte[] value = connection.get(key); String name = redisTemplate.getStringSerializer().deserialize(value); User user = new User(); user.setName(name); user.setId(id); return user; } return null; } }); } }
User：
public class User { private long id; private String name; public long getId() { return id; } public void setId(long id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } }
測試代碼：
public static void main(String[] args) { ApplicationContext ac = new ClassPathXmlApplicationContext("classpath:/applicationContext.xml"); UserDAO userDAO = (UserDAO)ac.getBean("userDAO"); User user1 = new User(); user1.setId(1); user1.setName("obama"); userDAO.saveUser(user1); User user2 = userDAO.getUser(1); System.out.println(user2.getName()); }
