我想把redis docker组件连接到spring引导会话。docker组件已启动并运行

  1. Steins-MacBook-Air:~ steinkorsveien$ docker exec -it some-redis sh -c "redis-cli"
  2. 127.0.0.1:6379> exit

在application.properties文件中

  1. spring.redis.host=localhost
  2. spring.redis.password=secret
  3. spring.redis.port=6379

我还添加了配置

  1. package org.steinko.atm;
  3. import org.springframework.session.data.redis.config.annotation.web.http.EnableRedisHttpSession;
  5. @EnableRedisHttpSession
  6. public class HttpSessionConfig {
  8. }

我运行gradle bootrun时收到一个错误

gradle.build中的依赖项如下所示

  1. dependencies {
  2.     implementation 'org.springframework.boot:spring-boot-starter-web:2.3.0.RELEASE'
  3.     implementation 'net.logstash.logback:logstash-logback-encoder:6.3'
  4.   // https://mvnrepository.com/artifact/org.springframework.session/spring-session
  5.   compile group: 'org.springframework.session', name: 'spring-session', version: '1.3.5.RELEASE'
  6.   // https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-data-redis
  7.    compile group: 'org.springframework.boot', name: 'spring-boot-starter-data-redis', version: '2.3.1.RELEASE'
  9.     testImplementation 'io.rest-assured:spring-mock-mvc:4.3.0'
  10.     testImplementation 'org.springframework.boot:spring-boot-starter-test:2.3.0.RELEASE'
  11. }

如何修复此错误并连接到redis？

为了创建redis模板bean，您需要添加以下配置。

  1. @Bean
  2. JedisConnectionFactory jedisConnectionFactory() {
  3.     return new JedisConnectionFactory();
  4. }
  5. @Bean
  6. public RedisTemplate<String, Object> redisTemplate() {
  7.     final RedisTemplate<String, Object> template = new RedisTemplate<String, Object>();
  8.     template.setConnectionFactory(jedisConnectionFactory());
  9.     template.setValueSerializer(new GenericToStringSerializer<Object>(Object.class));
  10.     return template;
  11. }
