将通用 redis 代码转换为 Azure Redis 缓存答案

【问题标题】：Converting generic redis code to Azure Cache for Redis将通用 redis 代码转换为 Azure Redis 缓存

【问题描述】：

我有以下 Spring Session 代码：

@Bean
public LettuceConnectionFactory connectionFactory() {
    String hostName = AcmeProperty.getProperty("spring.redis.host", "localhost");
    int port = Integer.parseInt(AcmeProperty.getProperty("spring.redis.port", "6379"));
    RedisStandaloneConfiguration redisStandaloneConfiguration = new RedisStandaloneConfiguration(hostName, port);

    return new LettuceConnectionFactory(redisStandaloneConfiguration);
}

当我在本地运行 redis 时，它可以很好地使用以下设置：

spring.redis.host=localhost
spring.redis.port=6379

但是，当我通过以下设置使用 Azure Cache for Redis 时：

spring.redis.host=acmedev.redis.cache.windows.net
spring.redis.port=6380

我收到此警告，应用程序挂起：

WARN (org.springframework.session.config.annotation.web.http.SpringHttpSessionConfiguration:166) || - Unable to obtain SessionCookieConfig: Section 4.4 of the Servlet 3.0 specification does not permit this method to be called from a ServletContextListener that was not defined in web.xml, a web-fragment.xml file nor annotated with @WebListener

我需要进行哪些更改才能使其与 Azure Cache for Redis 一起使用？

我试过this code，但同样的事情发生了：

@Bean
public JedisConnectionFactory connectionFactory() {
    String hostName = AcmeProperty.getProperty("spring.redis.host", "localhost");
    int port = Integer.parseInt(AcmeProperty.getProperty("spring.redis.port", "6379"));
    String password = AcmeProperty.getProperty("spring.redis.password");

    SSLSocketFactory sslSocketFactory = (SSLSocketFactory) SSLSocketFactory.getDefault();
    SSLParameters sslParameters = new SSLParameters();
    sslParameters.setEndpointIdentificationAlgorithm("HTTPS");
    sslParameters.setProtocols(new String[]{"TLSv1.2"});

    String uriStr = String.format("rediss://%s:%s", hostName, port);
    URI uri = URI.create(uriStr);
    JedisShardInfo shardInfo = new JedisShardInfo(uri, sslSocketFactory, sslParameters, null);

    shardInfo.setPassword(password);

    return new JedisConnectionFactory(shardInfo);
}

【解决方案1】：

您需要使用 XML Spring 配置； Java 配置不起作用。见"Unable to obtain SessionCookieConfig"。

<util:constant id="configureRedisAction"
               static-field="org.springframework.session.data.redis.config.ConfigureRedisAction.NO_OP"/>

<context:annotation-config/>
<bean class="org.springframework.session.data.redis.config.annotation.web.http.RedisHttpSessionConfiguration"
      p:configureRedisAction-ref="configureRedisAction"/>

<bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig">
    <property name="maxTotal" value="200" />
    <property name="maxIdle" value="50" />
    <property name="maxWaitMillis" value="30000" />
    <property name="minIdle" value="10"/>
</bean>

<bean class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory">
    <property name="hostName" value="${spring.redis.host}" />
    <property name="port" value="${spring.redis.port}" />
    <property name="poolConfig" ref="jedisPoolConfig" />
    <property name="usePool" value="true" />
    <property name="useSsl" value="${spring.redis.ssl}"/>
    <property name="password" value="${spring.redis.password}"/>
</bean>
