带有Redis的Spring启动会话中的错误-没有类型为[…SessionRepository]的合格Bean

Question

我正在遵循官方的Spring教程，将Redis会话支持添加到Spring Boot。

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

的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>
    ...

从1.3.0.RELEASE ，我没有在Spring会话中添加该版本1.3.0.RELEASE Boot的发布已经包含了jar。 即使按照教程添加版本1.0.2.RELEASE也无法解决我的问题

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

组态

@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。 甚至添加密码也无法解决我的问题。

当我运行应用程序时，出现以下错误

原因：..NoSuchBeanDefinitionException：未找到依赖项为[... SessionRepository]类型的合格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。

尝试这个 ：

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

Answer 2

这些是我要解决此问题的步骤：

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;
  }
}
