SpringBoot中Shiro缓存使用Redis、Ehcache的方法

2023-08-15 01:09:05 307

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


org.springframework.boot
spring-boot-starter-data-redis


org.springframework.session
spring-session-data-redis

配置redisConfig

@Configuration
@EnableCaching
publicclassRedisConfigextendsCachingConfigurerSupport{
@Bean
publicKeyGeneratorkeyGenerator(){
returnnewKeyGenerator(){
@Override
publicObjectgenerate(Objecttarget,Methodmethod,Object...params){
StringBuildersb=newStringBuilder();
sb.append(target.getClass().getName());
sb.append(method.getName());
for(Objectobj:params){
sb.append(obj.toString());
}
returnsb.toString();
}
};
}


@Bean
//在这里配置缓存reids配置
publicRedisCacheManagercacheManager(RedisConnectionFactoryredisConnectionFactory){
RedisCacheConfigurationredisCacheConfiguration=RedisCacheConfiguration.defaultCacheConfig()
.entryTtl(Duration.ofHours(1));//设置缓存有效期一小时
System.out.println("《========【开启redis】========》");
returnRedisCacheManager
.builder(RedisCacheWriter.nonLockingRedisCacheWriter(redisConnectionFactory))
.cacheDefaults(redisCacheConfiguration).build();
}

@Bean
publicRedisTemplateredisTemplate(RedisConnectionFactoryfactory){
StringRedisTemplatetemplate=newStringRedisTemplate(factory);
Jackson2JsonRedisSerializerjackson2JsonRedisSerializer=newJackson2JsonRedisSerializer(Object.class);
ObjectMapperom=newObjectMapper();
om.setVisibility(PropertyAccessor.ALL,JsonAutoDetect.Visibility.ANY);
om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
jackson2JsonRedisSerializer.setObjectMapper(om);
template.setValueSerializer(jackson2JsonRedisSerializer);
template.afterPropertiesSet();
returntemplate;
}

}

配置自定义缓存管理器，引入redis缓存管理器

定义自己的CacheManager

/**
*自定义cacheManage扩张shiro里面的缓存使用reids作缓存
*
*引入自己定义的CacheManager
*关于CacheManager的配置文件在spring-redis-cache.xml中
*
*/
@Component
publicclassShiroSpringCacheManagerimplementsCacheManager,Destroyable{
/**
*将之上的RedisCacheManager的Bean拿出来注入于此
*/
@Autowired
privateorg.springframework.cache.CacheManagercacheManager;

publicorg.springframework.cache.CacheManagergetCacheManager(){
returncacheManager;
}

publicvoidsetCacheManager(org.springframework.cache.CacheManagercacheManager){
this.cacheManager=cacheManager;
}

@Override
publicvoiddestroy()throwsException{
cacheManager=null;
}

@Override
publicCachegetCache(Stringname){
if(name==null){
returnnull;
}
//新建一个ShiroSpringCache将Bean放入并实例化
returnnewShiroSpringCache(name,getCacheManager());
}


}

定义自己实现的Shiro的Cache,实现了Shiro包里的Cache

/**
*自定义缓存将数据存入到redis中
*/
@SuppressWarnings("unchecked")
publicclassShiroSpringCacheimplementsorg.apache.shiro.cache.Cache{
privatestaticfinalLoggerlog=LoggerFactory.getLogger(ShiroSpringCache.class);
privateCacheManagercacheManager;
privateCachecache;

publicShiroSpringCache(Stringname,CacheManagercacheManager){
if(name==null||cacheManager==null){
thrownewIllegalArgumentException("cacheManagerorCacheNamecannotbenull.");
}
this.cacheManager=cacheManager;
//这里首先是从父类中获取这个cache,如果没有会创建一个redisCache,初始化这个redisCache的时候
//会设置它的过期时间如果没有配置过这个缓存的，那么默认的缓存时间是为0的，如果配置了，就会把配置的时间赋予给这个RedisCache
//如果从缓存的过期时间为0，就表示这个RedisCache不存在了，这个redisCache实现了spring中的cache
this.cache=cacheManager.getCache(name);
}
@Override
publicVget(Kkey)throwsCacheException{
log.info("从缓存中获取key为{}的缓存信息",key);
if(key==null){
returnnull;
}
ValueWrappervalueWrapper=cache.get(key);
if(valueWrapper==null){
returnnull;
}
return(V)valueWrapper.get();
}

@Override
publicVput(Kkey,Vvalue)throwsCacheException{
log.info("创建新的缓存，信息为：{}={}",key,value);
cache.put(key,value);
returnget(key);
}

@Override
publicVremove(Kkey)throwsCacheException{
log.info("干掉key为{}的缓存",key);
Vv=get(key);
cache.evict(key);//干掉这个名字为key的缓存
returnv;
}

@Override
publicvoidclear()throwsCacheException{
log.info("清空所有的缓存");
cache.clear();
}

@Override
publicintsize(){
returncacheManager.getCacheNames().size();
}

/**
*获取缓存中所的key值
*/
@Override
publicSetkeys(){
return(Set)cacheManager.getCacheNames();
}

/**
*获取缓存中所有的values值
*/
@Override
publicCollectionvalues(){
return(Collection)cache.get(cacheManager.getCacheNames()).get();
}

@Override
publicStringtoString(){
return"ShiroSpringCache[cache="+cache+"]";
}
}

到此为止，使用redis做缓存，和spring的集成就完成了。

可以使用以下注解将缓存放入redis

@Cacheable(value=Cache.CONSTANT,key="'"+CacheKey.DICT_NAME+"'+#name+'_'+#val")

配置springsession管理器

@Bean
@ConditionalOnProperty(prefix="xpro",name="spring-session-open",havingValue="true")
publicServletContainerSessionManagerservletContainerSessionManager(){
returnnewServletContainerSessionManager();
}

新建类springsession设置session过期时间

/**
*springsession配置
*
*@authorxingri
*@date2017-07-1321:05
*/
@EnableRedisHttpSession(maxInactiveIntervalInSeconds=900)//session过期时间如果部署多机环境,需要打开注释
@ConditionalOnProperty(prefix="xpro",name="spring-session-open",havingValue="true")
publicclassSpringSessionConfig{

}

第一种：Ehcache做缓存，可以将数据存储到磁盘中，也可以存到内存中

新建ehcache.xml文件

配置自定义缓存管理器，引入ehcache缓存管理器

/**
*ehcache配置
*
*/
@Configuration
@EnableCaching
publicclassEhCacheConfig{

/**
*EhCache的配置
*/
@Bean
publicEhCacheCacheManagercacheManager(CacheManagercacheManager){
MBeanServermBeanServer=ManagementFactory.getPlatformMBeanServer();
ManagementService.registerMBeans(cacheManager,mBeanServer,true,true,true,true);
returnnewEhCacheCacheManager(cacheManager);
}

/**
*EhCache的配置
*/
@Bean
publicEhCacheManagerFactoryBeanehcache(){
System.out.println("《========【开启ehcache】========》");
EhCacheManagerFactoryBeanehCacheManagerFactoryBean=newEhCacheManagerFactoryBean();
ehCacheManagerFactoryBean.setConfigLocation(newClassPathResource("ehcache.xml"));
returnehCacheManagerFactoryBean;
}

@Bean
publicorg.apache.shiro.cache.CacheManagergetCacheShiroManager(EhCacheManagerFactoryBeanehcache){
EhCacheManagerehCacheManager=newEhCacheManager();
ehCacheManager.setCacheManager(ehcache.getObject());
returnehCacheManager;
}
}

最后最重要的是引入shriro中

/**
*shiro权限管理的配置
*
*/
@Configuration
publicclassShiroConfig{

/**
*安全管理器
*/
@Bean
publicDefaultWebSecurityManagersecurityManager(CookieRememberMeManagerrememberMeManager,CacheManagercacheShiroManager,SessionManagersessionManager){
DefaultWebSecurityManagersecurityManager=newDefaultWebSecurityManager();
securityManager.setAuthenticator(modularRealmAuthenticator());

Listrealms=newArrayList<>();
securityManager.setRealms(realms);

securityManager.setCacheManager(cacheShiroManager);

securityManager.setRememberMeManager(rememberMeManager);
securityManager.setSessionManager(sessionManager);
returnsecurityManager;
}


/**
*springsession管理器（多机环境）
*/
@Bean
publicServletContainerSessionManagerservletContainerSessionManager(){
returnnewServletContainerSessionManager();
}

/**
*session管理器(单机环境)使用cookie存储缓存。。如果多级请注释
*/
@Bean
publicDefaultWebSessionManagerdefaultWebSessionManager(CacheManagercacheShiroManager,XProPropertiesxProProperties){
DefaultWebSessionManagersessionManager=newDefaultWebSessionManager();
sessionManager.setCacheManager(cacheShiroManager);
sessionManager.setSessionValidationInterval(xProProperties.getSessionValidationInterval()*1000);
sessionManager.setGlobalSessionTimeout(xProProperties.getSessionInvalidateTime()*1000);
sessionManager.setDeleteInvalidSessions(true);
sessionManager.setSessionValidationSchedulerEnabled(true);
Cookiecookie=newSimpleCookie(ShiroHttpSession.DEFAULT_SESSION_ID_NAME);
cookie.setName("shiroCookie");
cookie.setHttpOnly(true);
sessionManager.setSessionIdCookie(cookie);
returnsessionManager;
}



/**
*缓存管理器使用Ehcache实现如果使用redis则注释下面内容！！！！
*/
@Bean
publicCacheManagergetCacheShiroManager(EhCacheManagerFactoryBeanehcache){
EhCacheManagerehCacheManager=newEhCacheManager();
ehCacheManager.setCacheManager(ehcache.getObject());
returnehCacheManager;
}



/**
*项目自定义的Realm
*/
@Bean
publicShiroDbRealmshiroDbRealm(){
returnnewShiroDbRealm();
}

@Bean
publicShiroTockenRealmshiroTockenRealm(){
returnnewShiroTockenRealm();
}

@Bean
publicShiroJwtRealmshiroJwtRealm(){
returnnewShiroJwtRealm();
}

/**
*系统自带的Realm管理，主要针对多realm
**/
@Bean
publicModularRealmAuthenticatormodularRealmAuthenticator(){
ModularRealmAuthenticatormodularRealmAuthenticator=newModularRealmAuthenticator();
modularRealmAuthenticator.setAuthenticationStrategy(newAtLeastOneSuccessfulStrategy());
returnmodularRealmAuthenticator;
}
/**
*rememberMe管理器,cipherKey生成见{@codeBase64Test.java}
*/
@Bean
publicCookieRememberMeManagerrememberMeManager(SimpleCookierememberMeCookie){
CookieRememberMeManagermanager=newCookieRememberMeManager();
manager.setCipherKey(Base64.decode("Z3VucwAAAAAAAAAAAAAAAA=="));
manager.setCookie(rememberMeCookie);
returnmanager;
}

/**
*记住密码Cookie
*/
@Bean
publicSimpleCookierememberMeCookie(){
SimpleCookiesimpleCookie=newSimpleCookie("rememberMe");
simpleCookie.setHttpOnly(true);
simpleCookie.setMaxAge(7*24*60*60);//7天
returnsimpleCookie;
}


/**
*在方法中注入securityManager,进行代理控制
*/
@Bean
publicMethodInvokingFactoryBeanmethodInvokingFactoryBean(DefaultWebSecurityManagersecurityManager){
MethodInvokingFactoryBeanbean=newMethodInvokingFactoryBean();
bean.setStaticMethod("org.apache.shiro.SecurityUtils.setSecurityManager");
bean.setArguments(newObject[]{securityManager});
returnbean;
}

/**
*保证实现了Shiro内部lifecycle函数的bean执行
*/
@Bean
publicLifecycleBeanPostProcessorlifecycleBeanPostProcessor(){
returnnewLifecycleBeanPostProcessor();
}

/**
*启用shrio授权注解拦截方式，AOP式方法级权限检查
*/
@Bean
@DependsOn(value="lifecycleBeanPostProcessor")//依赖其他bean的初始化
publicDefaultAdvisorAutoProxyCreatordefaultAdvisorAutoProxyCreator(){
returnnewDefaultAdvisorAutoProxyCreator();
}

@Bean
publicAuthorizationAttributeSourceAdvisorauthorizationAttributeSourceAdvisor(DefaultWebSecurityManagersecurityManager){
AuthorizationAttributeSourceAdvisorauthorizationAttributeSourceAdvisor=
newAuthorizationAttributeSourceAdvisor();
authorizationAttributeSourceAdvisor.setSecurityManager(securityManager);
returnauthorizationAttributeSourceAdvisor;
}

}
