github example repo: https://github.com/dongjx/spring-boot-example
在上一篇spring-boot的搭建基础上，加入redis
spring-boot 提供的cache功能
- 在
application.yml里面加入CacheType, 默认是NONE
spring:
cache:
type: redis
- 在
XXXApplication.java里开启缓存功能
@SpringBootApplication
**@EnableCaching**
public class CatteryApplication {
public static void main(String[] args) {
SpringApplication.run(CatteryApplication.class, args);
}
}
spring-boot + redis
spring-boot + 单机redis
build.gradle加入redis相关的插件
compile('org.springframework.boot:spring-boot-starter-data-redis')
compile('redis.clients:jedis')
- 在
resources目录下加入redis.properties并设置对应的配置信息
spring.redis.database=0
spring.redis.host=localhost
spring.redis.port=6379
spring.redis.password=
- 在
configration中建立RedisConfig.java并引入redis.properties
@SpringBootConfiguration
@PropertySource("classpath:redis.properties")
public class RedisConfig {
}
- 使用
RedisTemplate来操作redis
//RedisTemplate 已经通过spring-boot-starter-data-redis的RedisAutoConfiguration自动注入了
ValueOperations<String, String> ops = redisTemplate.opsForValue();
ops.set("test1", "123"); //RedisTemplate操作redis时key会默认有前缀，所以这个例子redis里面的key是xxxtest1
String value = ops.get("test1");
- 使用spring-boot的cachable,
@EnableCaching时才能生效
@Service
public class RoleService {
@Autowired
private RoleRepository roleRepository;
@Cacheable(value = "roles")
public List<Role> findRoles() {
return StreamSupport.stream(roleRepository.findAll().spliterator(), false).collect(Collectors.toList());
}
}
spring-boot + 集群redis
-
redis.properties加入spring.redis.cluster.nodes=127.0.0.1:7000,127.0.0.1:7001,127.0.0.1:7002,127.0.0.1:7003,127.0.0.1:7004,127.0.0.1:7005 -
创建
RedisClusterProperties.java
@Component
@PropertySource("classpath:redis.properties")
@ConfigurationProperties(prefix = "spring.redis.cluster")
public class RedisClusterProperties {
List<String> nodes;
public List<String> getNodes() {
return nodes;
}
public void setNodes(List<String> nodes) {
this.nodes = nodes;
}
}
- 修改
redisConfig.java
@SpringBootConfiguration
public class RedisConfig {
@Autowired
RedisClusterProperties clusterProperties;
@Bean
public RedisConnectionFactory redisConnectionFactory() {
return new JedisConnectionFactory(new RedisClusterConfiguration(clusterProperties.getNodes()));
}
}
