SpringBoot中中Shiro缓存使用缓存使用Redis、、Ehcache的方法的方法
主要介绍了SpringBoot中Shiro缓存使用Redis、Ehcache的方法，文中通过示例代码介绍的非常详细，对大家的学习或者工作具有一定的参考学习价
值，需要的朋友们下面随着小编来一起学习学习吧
SpringBoot 中配置redis作为session 缓存器。 让shiro引用
本文是建立在你是使用这shiro基础之上的补充内容
第一种：Redis缓存，将数据存储到redis 并且开启session存入redis中。
引入pom
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.session</groupId>
<artifactId>spring-session-data-redis</artifactId>
</dependency>
配置redisConfig
@Configuration
@EnableCaching
public class RedisConfig extends CachingConfigurerSupport {
@Bean
public KeyGenerator keyGenerator() {
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
//在这里配置缓存reids配置
public RedisCacheManager cacheManager(RedisConnectionFactory redisConnectionFactory) {
RedisCacheConfiguration redisCacheConfiguration = RedisCacheConfiguration.defaultCacheConfig()
.entryTtl(Duration.ofHours(1)); // 设置缓存有效期一小时
System.out.println("《========【开启redis】 ======== 》 ");
return RedisCacheManager
.builder(RedisCacheWriter.nonLockingRedisCacheWriter(redisConnectionFactory))
.cacheDefaults(redisCacheConfiguration).build();
}
@Bean
public RedisTemplate<String, String> redisTemplate(RedisConnectionFactory factory) {
StringRedisTemplate template = new StringRedisTemplate(factory);
Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);
ObjectMapper om = new ObjectMapper();
om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
jackson2JsonRedisSerializer.setObjectMapper(om);
template.setValueSerializer(jackson2JsonRedisSerializer);
template.afterPropertiesSet();
return template;
}
}
配置自定义缓存管理器，引入redis缓存管理器
定义自己的CacheManager
/**
* <p> 自定义cacheManage 扩张shiro里面的缓存 使用reids作缓存 </p>
* <description>
* 引入自己定义的CacheManager
* 关于CacheManager的配置文件在spring-redis-cache.xml中
* </description>
*/
@Component
public class ShiroSpringCacheManager implements CacheManager ,Destroyable{
/**
* 将之上的RedisCacheManager的Bean拿出来 注入于此
*/
@Autowired
private org.springframework.cache.CacheManager cacheManager;
public org.springframework.cache.CacheManager getCacheManager() {
return cacheManager;
}
public void setCacheManager(org.springframework.cache.CacheManager cacheManager) {
this.cacheManager = cacheManager;
}
@Override
public void destroy() throws Exception {
cacheManager = null;
}
@Override
public <K, V> Cache<K, V> getCache(String name) {
