用的是最新的jedis-2.6.2.jar这个包，这个和以前的有点不同。还需要添加spring-data-redis-1.2.1.RELEASE.jar和commons-pool2-2.3.jar。
在类路径下创建spring-redis-config.xml文件
<?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"> <bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="locations" value="classpath:redis.properties"/> </bean> <bean id="poolConfig" class="redis.clients.jedis.JedisPoolConfig"> <property name="maxIdle" value="300" /> <property name="maxTotal" value="512" /> <property name="maxWaitMillis" value="1000" /> <property name="testOnBorrow" value="true" /> </bean> <bean id="connectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory" p:host-name="localhost" p:port="6379" p:password="" p:pool-config-ref="poolConfig"/> <bean id="redisTemplate" class="org.springframework.data.redis.core.StringRedisTemplate"> <property name="connectionFactory" ref="connectionFactory" /> </bean> </beans>
由于引用配置文件，使用不了表达式，这里写死了。使用表达式启动就报错，我也不知道为什么。
##
redis.host=localhost
##
redis.port=6379
##
redis.pass=
##
redis.maxIdle=300
##
redis.maxTotal=512
##
redis.maxWaitMillis=1000
##
redis.testOnBorrow=true
redis.properties文件配置。
以前的版本应该有配置redis.maxActive但是看了源码，是没有setMaxActive方法的，所以不能注入，改用了redis.maxTotal。就因为这个弄了挺长时间的。
在web.xml配置spring-redis-config.xml文件
<context-param> <param-name>contextConfigLocation</param-name> <param-value> <!-- 多个配置用,隔开 --> classpath*:spring-redis-config.xml </param-value> </context-param>
import org.springframework.beans.factory.annotation.Autowired; import org.springframework.data.redis.core.RedisTemplate; import org.springframework.data.redis.serializer.RedisSerializer; public abstract class AbstractBaseRedisDao<V, K> { @Autowired protected RedisTemplate<K, V> redisTemplate; public void setRedisTemplate(RedisTemplate<K, V> redisTemplate) { this.redisTemplate = redisTemplate; } /** * 获取 RedisSerializer * <br>------------------------------<br> */ protected RedisSerializer<String> getRedisSerializer() { return redisTemplate.getStringSerializer(); } }
创建一个抽象类，然后让使用到的类都继承这个方法。
@Service("areaRedisService")
public class AreaRedisService<V, K> extends AbstractBaseRedisDao<V, K> {
public boolean add(final Area area) {
boolean result = redisTemplate.execute(new RedisCallback<Boolean>() {
public Boolean doInRedis(RedisConnection connection) throws DataAccessException {
RedisSerializer<String> serializer = getRedisSerializer();
byte[] key = serializer.serialize(area.getId()+"");
byte[] name = serializer.serialize(area.getName());
return connection.setNX(key, name);
}
});
return result;
}
public Area get(final String keyId) {
Area result = redisTemplate.execute(new RedisCallback<Area>() {
public Area doInRedis(RedisConnection connection)
throws DataAccessException {
RedisSerializer<String> serializer = getRedisSerializer();
byte[] key = serializer.serialize(keyId);
byte[] value = connection.get(key);
if (value == null) {
return null;
}
String name = serializer.deserialize(value);
return new Area(Integer.valueOf(keyId),name,null);
}
});
return result;
}
}
@Autowired AreaRedisService<?, ?> areaRedisService; private String path = "/WEB-INF/jsp/"; @RequestMapping("/area/redis.htm") public ModelAndView areaRedis(HttpServletRequest request, HttpServletResponse response,String name) throws Exception { ModelAndView mv = new ModelAndView(path+"add.html"); Area area = new Area(); area.setCreateTime(new Date()); area.setCommon(true); area.setDeleteStatus(false); area.setLevel(4); area.setName(name); area.setParentId(null); area.setSequence(1); area.setId(1); areaRedisService.add(area); mv.addObject("area", area); mv.addObject("arearedis",areaRedisService.get(area.getId()+"")); return mv; }
这是controller的方法，这里使用了spring的注解。
使用注解，需要在上面的spring-redis-config.xml文件加入<context:component-scan base-package="基础包路径"/>配置了扫描路径可以不配置<context:annotation-config/>，因为前面的包含了后面的，他会激活@Controller,@Service,@Autowired,@Resource,@Component等注解。
