java - 如何使用/导入 @EnableRedisHttpSession Spring 注释？

Question

我正在尝试遵循 https://docs.spring.io/spring-session/docs/current/reference/html5/guides/java-redis.html 上的 Spring 教程.
我添加了列出的依赖项，但 @EnableRedisHttpSession 无法解析为类型。

我是 Spring 新手，所以也许我错过了一些明显的东西，但我确实看到这个注释存在于 api 文档中 https://docs.spring.io/spring-session/docs/current/api/index.html?org/springframework/session/data/redis/config/annotation/web/http/EnableRedisHttpSession.html .

我的pom.xml:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">

            </plugin>
        </plugins>
    </build>

</project> 

和我的 Config.java :

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.connection.lettuce.LettuceConnectionFactory;

@EnableRedisHttpSession 
public class Config {

    @Bean
    public LettuceConnectionFactory connectionFactory() {
        return new LettuceConnectionFactory(); 
    }
}

我错过了什么？任何帮助表示赞赏。

Answer 1

将以下依赖项添加到您的 pom.xml :

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

并删除:

<dependency>
  <groupId>org.springframework.session</groupId>
  <artifactId>spring-session-data-redis</artifactId>
  <version>2.1.8.RELEASE</version>
  <type>pom</type>
</dependency>

基本上，你应该输入 <type>pom</type> <dependencyManagement> 中的依赖项pom.xml的部分。另外，您在使用 spring-boot-starter-parent 时不需要版本。 .

此外，要启用 Spring Boot 自动配置，请使用 @EnableRedisHttpSession类上还注释有 @Configuration ，或者将其与您的 @SpringBootApplication 添加在一起。因此，例如您应该有这样的内容:

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