Spring boot后台搭建二为Shiro权限控制添加缓存

为了避免频繁访问数据库获取权限信息,在Shiro中加入缓存

缓存有基于Redis和Ehcache的

基于Redis

1.Shiro集成Redis的引入依赖

<dependency>
<groupId>org.crazycake</groupId>
<artifactId>shiro-redis</artifactId>
</dependency>

2.Redis配置

spring.redis.host=localhost
spring.redis.port=6379
spring.redis.jedis.pool.max-active=8
spring.redis.jedis.pool.max-wait=-1
spring.redis.jedis.pool.max-idle=8
spring.redis.jedis.pool.min-idle=0
spring.redis.timeout=0

3.在ShiroConfig中配置Redis

public RedisManager redisManager() {
RedisManager redisManager = new RedisManager();
return redisManager;
} public RedisCacheManager cacheManager() {
RedisCacheManager redisCacheManager = new RedisCacheManager();
redisCacheManager.setRedisManager(redisManager());
return redisCacheManager;
}

在SecurityManager中加入RedisCacheManager

@Bean
public SecurityManager securityManager() {
DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
……
securityManager.setCacheManager(cacheManager());
return securityManager;
}

4.测试

启动项目

访问访问”获取用户信息”、”新增用户”和”删除用户”,后台只打印一次获取权限信息

基于Ehcache

1.添加依赖

<!-- shiro ehcache -->
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-ehcache</artifactId>
<version>1.4.1</version>
</dependency>
<!-- ehchache -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-cache</artifactId>
</dependency>
<dependency>
<groupId>net.sf.ehcache</groupId>
<artifactId>ehcache</artifactId>
</dependency>

2.添加配置

src\main\resources\config下添加shiro-ehcache.xml

<?xml version="1.0" encoding="UTF-8"?>
<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="http://ehcache.org/ehcache.xsd"
updateCheck="false">
<diskStore path="java.io.tmpdir/Tmp_EhCache"/>
<defaultCache
maxElementsInMemory="10000"
eternal="false"
timeToIdleSeconds="120"
timeToLiveSeconds="120"
overflowToDisk="false"
diskPersistent="false"
diskExpiryThreadIntervalSeconds="120"/> <!-- 登录记录缓存锁定1小时 -->
<cache
name="passwordRetryCache"
maxEntriesLocalHeap="2000"
eternal="false"
timeToIdleSeconds="3600"
timeToLiveSeconds="0"
overflowToDisk="false"
statistics="true"/>
</ehcache>

3.在ShiroConfig中

  注入Ehcache缓存

  添加getEhCacheManager()

@Bean
public EhCacheManager getEhCacheManager() {
EhCacheManager em = new EhCacheManager();
em.setCacheManagerConfigFile("classpath:config/shiro-ehcache.xml");
return em;
}

  将缓存对象注入到SecurityManager中

  修改securityManager()

@Bean
public SecurityManager securityManager() {
DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
securityManager.setRealm(myShiroRealm());
securityManager.setRememberMeManager(rememberMeManager());
securityManager.setCacheManager(getEhCacheManager());
return securityManager;
}

4.测试

  启动项目,分别访问访问”获取用户信息”、”新增用户”,只获取一次权限信息
