使用spring-session-data-redis做session共享实现

1.pom.xml依赖

代码语言：javascript复制

<!--        spring-session-redis-->

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-redis</artifactId>
    <exclusions>
        <exclusion>
            <groupId>io.lettuce</groupId>
            <artifactId>lettuce-core</artifactId>
        </exclusion>
    </exclusions>
</dependency>
<dependency>
    <groupId>redis.clients</groupId>
    <artifactId>jedis</artifactId>
</dependency>


<!--spring boot 与redis应用基本环境配置 -->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>
<!--spring session 与redis应用基本环境配置,需要开启redis后才可以使用，不然启动Spring boot会报错 -->
<dependency>
    <groupId>org.springframework.session</groupId>
    <artifactId>spring-session-data-redis</artifactId>
</dependency>

2.application-redis.properties:

代码语言：javascript复制

#spring.redis.password=redis
spring.redis.pool.max-idle=8
spring.redis.pool.min-idle=0
spring.redis.pool.max-active=8
spring.redis.pool.max-wait=-1
spring.redis.timeout=5000
redis.hostname=127.0.0.1
redis.port=6379

3.SessionInitializer

代码语言：javascript复制

//初始化Session配置
public class SessionInitializer extends AbstractHttpSessionApplicationInitializer {
    public SessionInitializer() {
        super(SessionConfig.class);
    }
}

4.SessionConfig

代码语言：javascript复制

//这个类用配置redis服务器的连接
//maxInactiveIntervalInSeconds为SpringSession的过期时间（单位：秒）
@EnableRedisHttpSession(maxInactiveIntervalInSeconds = 1800)
public class SessionConfig {

    // 冒号后的值为没有配置文件时，制动装载的默认值
    @Value("${redis.hostname:localhost}")
    String HostName;
    @Value("${redis.port:6379}")
    int Port;
    @Value("${redis.password:redis}")
    String password;

    @Bean
    public JedisConnectionFactory connectionFactory() {
        JedisConnectionFactory connection = new JedisConnectionFactory();
        connection.setPort(Port);
        connection.setHostName(HostName);
//        connection.setPassword(password);
        return connection;
    }
}
