shiro-redis

Build Status

shiro only provide the support of ehcache and concurrentHashMap. Here is an implement of redis cache can be used by shiro. Hope it will help you!

Download

You can choose these 2 ways to include shiro-redis into your project

<dependency>
    <groupId>org.crazycake</groupId>
    <artifactId>shiro-redis</artifactId>
    <version>3.1.0</version>
</dependency>

Note:
Do not use version < 3.1.0
注意
请不要使用3.1.0以下版本

Before use

Here is the first thing you need to know. Shiro-redis needs an id field to identify your authorization object in Redis. So please make sure your principal class has a field which you can get unique id of this object. Please setting this id field name by cacheManager.principalIdFieldName = <your id field name of principal object>

For example:

If you create SimpleAuthenticationInfo like the following:

@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
    UsernamePasswordToken usernamePasswordToken = (UsernamePasswordToken)token;
    UserInfo userInfo = new UserInfo();
    userInfo.setUsername(usernamePasswordToken.getUsername());
    return new SimpleAuthenticationInfo(userInfo, "123456", getName());
}

Then the userInfo object is your principal object. You need to make sure UserInfo has an unique field to identify it in Redis. Take userId as an example:

public class UserInfo implements Serializable{

    private Integer userId

    private String username;

    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    public Integer getUserId() {
        return this.userId;
    }
}

Put userId as the value of cacheManager.principalIdFieldName, like this:

cacheManager.principalIdFieldName = userId

If you're using Spring, the configuration should be

<property name="principalIdFieldName" value="userId" />

Then shiro-redis will call userInfo.getUserId() to get the id for storing Redis object.

How to configure ?

You can configure shiro-redis either in shiro.ini or in spring-*.xml

shiro.ini

Here is the configuration for shiro.ini.

Redis Standalone

[main]
#====================================
# shiro-redis configuration [start]
#====================================

#===================================
# Redis Manager
#===================================

# Create redisManager
redisManager = org.crazycake.shiro.RedisManager

# Redis host. If you don't specify host the default value is 127.0.0.1:6379
redisManager.host = 127.0.0.1:6379

# Redis connect timeout. Timeout for jedis try to connect to redis server(In milliseconds).(Optional)
#
# redisManager.timeout = <timeout>

# Redis password.(Optional)
#
# redisManager.password = <password>

# Redis database. Default value is 0(Optional)
#
# redisManager.database = <database>

# JedisPoolConfig (Optional)
# Most of time, you don't need to set jedisPoolConfig
#
# jedisPoolConfig = redis.clients.jedis.JedisPoolConfig
# jedisPoolConfig.<attribute> = <value>
# redisManager.jedisPoolConfig = jedisPoolConfig

# Scan count. Shiro-redis use Scan to get keys, so you can define the number of elements returned at every iteration. (Optional)
#
# redisManager.count = <count>

#====================================
# Redis-based session configuration
#====================================

# Create redisSessionDAO
redisSessionDAO = org.crazycake.shiro.RedisSessionDAO

# Redis cache key/value expire time. The expire time is in second.
# Special values:
# -1: no expire
# -2: the same timeout with session
# Default value: -2
# Note: Make sure expire time is longer than session timeout.  (Optional)
#
# redisSessionDAO.expire = <expire>

# Custom your redis key prefix for session management
# Default value is "shiro:session:"
# Note: Remember to add colon at the end of prefix.
#
# redisSessionDAO.keyPrefix = <session key prefix>

# Use redisManager as cache manager
redisSessionDAO.redisManager = $redisManager

# doReadSession be called about 10 times when login. Save Session in ThreadLocal to resolve this problem. sessionInMemoryTimeout is expiration of Session in ThreadLocal.
# The default value is 1000 milliseconds (1s)
# Most of time, you don't need to change it.
#
# redisSessionDAO.sessionInMemoryTimeout = <timeout>

sessionManager = org.apache.shiro.web.session.mgt.DefaultWebSessionManager

sessionManager.sessionDAO = $redisSessionDAO

securityManager.sessionManager = $sessionManager

#=====================================
# Redis-based cache configuration
#=====================================

# Create cacheManager
cacheManager = org.crazycake.shiro.RedisCacheManager

# Principal id field name. The field which you can get unique id to identify this principal.
# For example, if you use UserInfo as Principal class, the id field maybe userId, userName, email, etc.
# Remember to add getter to this id field. For example, getUserId(), getUserName(), getEmail(), etc.
# Default value is authCacheKey or id, that means your principal object has a method called "getAuthCacheKey()" or "getId()"
#
# cacheManager.principalIdFieldName = id

# Redis cache key/value expire time. Default value: 1800 .The expire time is in second. (Optional)
#
# cacheManager.expire = <expire>

# If you want change charset of keySerializer or use your own custom serializer, you need to define serializer first
#
# cacheManagerKeySerializer = org.crazycake.shiro.serializer.StringSerializer

# Refer to https://docs.oracle.com/javase/8/docs/technotes/guides/intl/encoding.doc.html
# UTF-8, UTF-16, UTF-32, ISO-8859-1, GBK, Big5, etc
#
# cacheManagerKeySerializer.charset = UTF-8

# cacheManager.keySerializer = $cacheManagerKeySerializer

# Custom your redis key prefix for cache management
# Default value is "shiro:cache:"
# Note: Remember to add colon at the end of prefix.
#
# cacheManager.keyPrefix = <cache key prefix>

# Use redisManager as cache manager
cacheManager.redisManager = $redisManager

securityManager.cacheManager = $cacheManager

#=================================
# shiro-redis configuration [end]
#=================================

Here is a tutorial project for you to understand how to configure shiro-redis in shiro.ini.

Redis Sentinel

if you're using Redis Sentinel, please change the redisManager configuration into the following:

#===================================
# Redis Manager
#===================================

# Create redisManager
redisManager = org.crazycake.shiro.RedisSentinelManager

# Sentinel host. If you don't specify host the default value is 127.0.0.1:26379,127.0.0.1:26380,127.0.0.1:26381
redisManager.host = 127.0.0.1:26379,127.0.0.1:26380,127.0.0.1:26381

# Sentinel master name
redisManager.masterName = mymaster

# Redis connect timeout. Timeout for jedis try to connect to redis server(In milliseconds).(Optional)
#
# redisManager.timeout = <timeout>

# Timeout for jedis try to read data from redis server (Optional)
#
# redisManager.soTimeout = <soTimeout>

# Redis password.(Optional)
#
# redisManager.password = <password>

# Redis database. Default value is 0 (Optional)
#
# redisManager.database = <database>

# JedisPoolConfig (Optional)
# Most of time, you don't need to set jedisPoolConfig
#
# jedisPoolConfig = redis.clients.jedis.JedisPoolConfig
# jedisPoolConfig.<attribute> = <value>
# redisManager.jedisPoolConfig = jedisPoolConfig

# Scan count. Shiro-redis use Scan to get keys, so you can define the number of elements returned at every iteration. (Optional)
#
# redisManager.count = <count>

Redis Cluster

If you're using redis cluster, here is an example of configuration :

# Create redisManager
redisManager = org.crazycake.shiro.RedisClusterManager

# Redis host and port list
redisManager.host = 192.168.21.3:7000,192.168.21.3:7001,192.168.21.3:7002,192.168.21.3:7003,192.168.21.3:7004,192.168.21.3:7005

# Redis connect timeout. Timeout for jedis try to connect to redis server(In milliseconds).(Optional)
#
# redisManager.timeout = 2000

# timeout for jedis try to read data from redis server (Optional)
#
# redisManager.soTimeout = 2000

# max attempts to connect to server (Optional)
#
# redisManager.maxAttempts = 3

Redis Sentinel

If you use redis sentinel, here is an example of configuration :

<!-- shiro-redis configuration [start] -->
<!-- shiro redisManager -->
<bean id="redisManager" class="org.crazycake.shiro.RedisSentinelManager">
    <property name="host" value="127.0.0.1:26379,127.0.0.1:26380,127.0.0.1:26381"/>

    <property name="password" value=""/>
    <property name="database" value="0"/>
    <property name="count" value="100"/>
    -->
</bean>

Redis Cluster

If you use redis cluster, here is an example of configuration :

<!-- shiro-redis configuration [start] -->
<!-- shiro redisManager -->
<bean id="redisManager" class="org.crazycake.shiro.RedisClusterManager">
    <property name="host" value="192.168.21.3:7000,192.168.21.3:7001,192.168.21.3:7002,192.168.21.3:7003,192.168.21.3:7004,192.168.21.3:7005"/>
    <!-- optional properties
    <property name="timeout" value="10000"/>
    <property name="soTimeout" value="10000"/>
    <property name="maxAttempts" value="2"/>
    <property name="password" value="123456"/>
    -->
</bean>

Serializer

Since redis only accept byte[], there comes to a serializer problem. Shiro-redis is using StringSerializer as key serializer and ObjectSerializer as value serializer. You can use your own custom serializer, as long as this custom serializer implemens org.crazycake.shiro.serializer.RedisSerializer

For example, you need to change the charset of keySerializer.

# If you want change charset of keySerializer or use your own custom serializer, you need to define serializer first
#
# cacheManagerKeySerializer = org.crazycake.shiro.serializer.StringSerializer

# Refer to https://docs.oracle.com/javase/8/docs/technotes/guides/intl/encoding.doc.html
# UTF-8, UTF-16, UTF-32, ISO-8859-1, GBK, Big5, etc
#
# cacheManagerKeySerializer.charset = UTF-8

# cacheManager.keySerializer = $cacheManagerKeySerializer

These 4 Serializers are replaceable:

  • cacheManager.keySerializer
  • cacheManager.valueSerializer
  • redisSessionDAO.keySerializer
  • redisSessionDAO.valueSerializer
