使用 Redis 的 Spring 启动会话中的错误 - 没有 [...SessionRepository] ​​类型的限定 bean

Question

我正在关注spring官方教程，为spring boot添加redis session支持。

http://docs.spring.io/spring-session/docs/current/reference/html5/guides/boot.html

pom.xml

    ...
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.3.1.RELEASE</version>
    ...
        <groupId>org.springframework.session</groupId>
        <artifactId>spring-session</artifactId>
    ... 
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-redis</artifactId>
    ...

我没有从 Spring Boot 的1.3.0.RELEASE 开始将版本添加到 Spring 会话中，jar 包含在其中。即使按照教程添加版本1.0.2.RELEASE 也不能解决我的问题

请注意spring-boot 1.3.1.RELEASE，使用的spring版本是4.2.4.RELEASE

配置

@EnableRedisHttpSession
public class HttpSessionConfig {
}

属性文件

#redis
spring.redis.host=127.0.0.1
spring.redis.port=6379

我没有添加密码，因为我的 redis 服务器密码为空。即使添加密码也没有解决我的问题。

当我运行应用程序时，它会给出以下错误

原因：..NoSuchBeanDefinitionException：没有为依赖项找到类型为 [...SessionRepository] ​​的合格 bean：expect...endency。依赖注释：{}

我还为下面的参考添加了完整的错误堆栈

Answer 1

您缺少创建 RedisConnectionFactory 步骤。

试试这个：

@EnableRedisHttpSession
public class HttpSessionConfig {
        @Bean
        public JedisConnectionFactory connectionFactory() {
                return new JedisConnectionFactory(); 
        }
}

Answer 2

这些是我解决此问题所遵循的步骤：

1 - application.properties：

spring.session.store-type=redis
spring.redis.host=localhost
spring.redis.password=Password123OrSomething
spring.redis.port=1234

2 - pom.xml

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-core</artifactId>
    <version>4.3.3.RELEASE</version>
</dependency>

<dependency>
    <groupId>org.springframework.session</groupId>
    <artifactId>spring-session</artifactId>
    <version>1.3.0.RELEASE</version>
</dependency>

<dependency>
<groupId>org.springframework.data</groupId>
    <artifactId>spring-data-redis</artifactId>
    <version>1.7.4.RELEASE</version>
</dependency>

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>

3 - Redis 配置类（Spring Boot）：

@ConditionalOnProperty(name = "spring.session.store-type", havingValue = "redis")
@EnableRedisHttpSession
public class RedisSessionConfig {

  @Value("${spring.session.store-type}")
  private String sessionStoreType;

  private static final Logger LOGGER = LoggerFactory.getLogger(RedisSessionConfig.class);

  @PostConstruct
  public void init() {
    LOGGER.info("spring.session.store-type=none turns spring session off.");
    LOGGER.info("Redis Session Replication is turned {}.", sessionStoreType.equals("redis") ? "ON"
        : "OFF");
  }

  @Bean
  public ConfigureRedisAction configureRedisAction() {
    LOGGER.info("Preventing auto-configuration in secured environments.");
    return ConfigureRedisAction.NO_OP;
  }
}
