Spring セッションの Redis クラスター構成手順の概要

設定手順の概要

spring-session redis 設定ライフを開始する 4 つの簡単な手順

1. pom.xml jar 依存関係を追加します

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    ....

    <properties>
        <version.spring-session>1.2.2.RELEASE</version.spring-session>        <!--不兼容 1.7.4.RELEASE -->
        <version.spring-data-redis>1.7.1.RELEASE</version.spring-data-redis>

    </properties>

    <dependencies>

        ....

        <dependency>
            <groupId>org.springframework.session</groupId>
            <artifactId>spring-session</artifactId>
            <version>${version.spring-session}</version>
        </dependency>

        <dependency>
            <groupId>org.springframework.session</groupId>
            <artifactId>spring-session-data-redis</artifactId>
            <version>${version.spring-session}</version>
        </dependency>

        <dependency>
            <groupId>org.springframework.data</groupId>
            <artifactId>spring-data-redis</artifactId>
            <version>${version.spring-data-redis}</version>
        </dependency> 

        ....

    </dependencies>

</project>

2. web.xml に springSessionRepositoryFilter 設定を追加します

rreee-3.クラスター.xml ダウンロード

 <?xml version="1.0" encoding="UTF-8"?>
    <web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">

        ...        <!-- spring-session config -->
        <context-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>
                classpath*:spring-session-cluster.xml
            </param-value>
        </context-param>        <!-- 这个filter 要放在第一个 -->
        <filter>
            <filter-name>springSessionRepositoryFilter</filter-name>
            <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
        </filter>
        <filter-mapping>
            <filter-name>springSessionRepositoryFilter</filter-name>
            <url-pattern>/*</url-pattern>
            <dispatcher>REQUEST</dispatcher>
            <dispatcher>ERROR</dispatcher>
        </filter-mapping>
        ...
    </web-app>

4. redis-cluster.properties ダウンロード

    <?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
        xmlns:p="http://www.springframework.org/schema/p" xmlns:util="http://www.springframework.org/schema/util"
        xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd            http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd            http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util.xsd               ">

        <context:annotation-config />

        <util:properties id="redis" location="classpath:redis-cluster.properties"></util:properties>        <!-- RedisHttpSessionConfiguration -->
        <bean class="org.springframework.session.data.redis.config.annotation.web.http.RedisHttpSessionConfiguration" />        <!--JedisConnectionFactory -->
        <bean class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory">
            <constructor-arg index="0">                <!-- since spring-data-redis 1.7 -->
                <bean class="org.springframework.data.redis.connection.RedisClusterConfiguration">
                    <constructor-arg index="0">
                        <set>
                            <value>#{redis[&#39;redis.redisClusterConfiguration.clusters&#39;]}</value>
                        </set>
                    </constructor-arg>                    <!--                        用于 redis.clients.jedis.JedisCluster.JedisCluster(Set<HostAndPort>, int, int, GenericObjectPoolConfig) 第三个参数 maxRedirections                        默认值是5                        一般当此值设置过大时，容易报：Too many Cluster redirections                    -->
                    <property name="maxRedirects" value="#{redis[&#39;redis.redisClusterConfiguration.maxRedirects&#39;]}" />
                </bean>
            </constructor-arg>

            <constructor-arg index="1">
                <bean class="redis.clients.jedis.JedisPoolConfig">
                    <property name="maxIdle" value="#{redis[&#39;redis.jedisPoolConfig.MaxIdle&#39;]}" />
                    <property name="testOnBorrow" value="#{redis[&#39;redis.jedisPoolConfig.testOnBorrow&#39;]}" />
                    <property name="testOnReturn" value="#{redis[&#39;redis.jedisPoolConfig.testOnReturn&#39;]}" />                    <!-- 新版jedis 不支持这个参数了 -->
                    <!-- <property name="maxWait" value="#{redis[&#39;redis.jedisPoolConfig.MaxWait&#39;]}" /> -->
                    <!-- <property name="maxActive" value="#{redis[&#39;redis.jedisPoolConfig.MaxActive&#39;]}" /> -->
                </bean>
            </constructor-arg>
        </bean>

    </beans>
