只要加入spring-boot-starter-data-redis , springboot 会自动识别并使用redis作为缓存容器,使用方式如下
gradle加入依赖
compile("org.springframework.boot:spring-boot-starter-data-redis:${springBootVersion}")
redis configuration 中启用缓存
@Configuration @EnableCaching public class RedisConfiguration
redis 自定义key生成规则
@Bean
public KeyGenerator wiselyKeyGenerator() {
return new KeyGenerator() {
@Override
public Object generate(Object target, Method method, Object... params) {
StringBuilder sb = new StringBuilder();
sb.append(target.getClass().getName());
sb.append(":" + method.getName());
for (Object obj : params) {
sb.append(":" + obj.toString());
}
return sb.toString();
}
};
}
有时候我们需要 使用 redisTemplate, 可以这样子配置
@Bean public RedisConnectionFactory redisConnectionFactory() { return new JedisConnectionFactory(); } @Bean public RedisTemplate redisTemplate(RedisConnectionFactory redisConnectionFactory) { RedisTemplate redisTemplate = new RedisTemplate(); redisTemplate.setConnectionFactory(redisConnectionFactory); return redisTemplate; } @Bean public CacheManager cacheManager(RedisTemplate redisTemplate) { return new RedisCacheManager(redisTemplate); }
完整代码
package cn.xiaojf.today.data.redis.configuration; import org.springframework.cache.CacheManager; import org.springframework.cache.annotation.EnableCaching; import org.springframework.cache.interceptor.KeyGenerator; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.data.redis.cache.RedisCacheManager; import org.springframework.data.redis.connection.RedisConnectionFactory; import org.springframework.data.redis.connection.jedis.JedisConnectionFactory; import org.springframework.data.redis.core.RedisTemplate; import java.lang.reflect.Method; /** * redis 缓存配置 * @author xiaojf 2016/12/7 10:29. */ @Configuration @EnableCaching public class RedisConfiguration { @Bean public KeyGenerator wiselyKeyGenerator() { return new KeyGenerator() { @Override public Object generate(Object target, Method method, Object... params) { StringBuilder sb = new StringBuilder(); sb.append(target.getClass().getName()); sb.append(":" + method.getName()); for (Object obj : params) { sb.append(":" + obj.toString()); } return sb.toString(); } }; } @Bean public RedisConnectionFactory redisConnectionFactory() { return new JedisConnectionFactory(); } @Bean public RedisTemplate redisTemplate(RedisConnectionFactory redisConnectionFactory) { RedisTemplate redisTemplate = new RedisTemplate(); redisTemplate.setConnectionFactory(redisConnectionFactory); return redisTemplate; } @Bean public CacheManager cacheManager(RedisTemplate redisTemplate) { return new RedisCacheManager(redisTemplate); } }
使用例子
package cn.xiaojf.today.sys.dao.impl; import cn.xiaojf.today.base.dao.impl.BaseDaoImpl; import cn.xiaojf.today.base.model.PageInfo; import cn.xiaojf.today.base.util.Asserts; import cn.xiaojf.today.sys.dao.SysUserDao; import cn.xiaojf.today.sys.repository.SysUserRepository; import cn.xiaojf.today.sys.entity.SysUser; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.cache.annotation.CacheConfig; import org.springframework.stereotype.Repository; import java.util.HashSet; import java.util.List; import java.util.Map; import java.util.Set; /** * 用户数据访问接口实现类 * @author xiaojf 2017/2/9 17:40. */ @Repository @CacheConfig(cacheNames = {"sysUserCache"}) public class SysUserDaoImpl extends BaseDaoImpl<SysUser> implements SysUserDao { @Autowired private SysUserRepository userRepository; public SysUserDaoImpl() { super(SysUserRepository.class); } @Override // @Cacheable(key = "#username") public SysUser getByUsername(String username) { Asserts.notNull(username,"用户名不能为空"); SysUser user = userRepository.findFirstByUsername(username); return user; } }
spring cache的其他使用方式很简单,可以直接看官网或者百度例子
