使用Redis的Spring Boot会话中出错-没有符合条件的类型[...SessionRepository]

Question

我正在遵循spring官方教程，将redis会话支持添加到Spring Boot中。

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>
    ...

我没有将版本添加到spring会话中，因为从1.3.0开始。release启动了spring boot，jar包含在其中。即使按照教程添加1.0.2.release版本也没有解决我的问题

请注意spring-boot1.3.1.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

我没有添加秘密，因为我的redis服务器密码是空的。即使添加密码也不能解决我的问题。

当我运行应用程序时，它会出现以下错误

由：..NosuchBeanDefinitionException引起：没有为Dependency找到类型[...SessionRepository]的合格bean：Expect...Endency。依赖项批注：{}

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(); 
        }
}
