amazon-web-services - 将 Spring Boot 连接到 Redis : NoClassDefFoundError: org/springframework/session/hazelcast/HazelcastFlushMode

Question

所以我有一个 spring boot 应用程序，我试图连接到 AWS 上托管的 redis 集群以进行 session 完整错误是:

  Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'spring.session-org.springframework.boot.autoconfigure.session.SessionProperties': Bean instantiation via constructor failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.boot.autoconfigure.session.SessionProperties]: Constructor threw exception; nested exception is java.lang.NoClassDefFoundError: org/springframework/session/hazelcast/HazelcastFlushMode

在我的 build.gradle 中

buildscript {
ext {
    springBootVersion = '1.5.9.RELEASE'
}
repositories {
    mavenCentral()
}
dependencies {
    classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
}
   }

  apply plugin: 'java'
  apply plugin: 'eclipse'
  apply plugin: 'org.springframework.boot'

   group = 'haughton.daniel'
  version = '0.0.1-SNAPSHOT'
  sourceCompatibility = 1.8

  repositories {
mavenCentral()
  }  


   ext {
springCloudVersion = 'Edgware.SR1'
     }
  processResources {
from ('.ebextensions/') {
    into '.ebextensions'
}
    }


   dependencies {

compile('org.springframework.boot:spring-boot-starter-data-jpa')

compile group: 'org.springframework.boot', name: 'spring-boot-starter-mail', version: '2.0.0.RELEASE'

compile('org.springframework.boot:spring-boot-starter-jdbc')
compile('org.springframework.boot:spring-boot-starter-security')
compile('org.springframework.boot:spring-boot-starter-thymeleaf')

compile group: 'org.thymeleaf.extras', name: 'thymeleaf-extras-springsecurity4', version: '2.1.2.RELEASE'

compile group: 'mysql', name: 'mysql-connector-java', version: '6.0.6'

compile group: 'org.springframework.session', name: 'spring-session-data-redis', version: '2.0.2.RELEASE'


compile('org.springframework.boot:spring-boot-starter-web')
compile ('org.apache.tomcat:tomcat-dbcp:8.0.30')

runtime('mysql:mysql-connector-java')
testCompile('org.springframework.boot:spring-boot-starter-test')
testCompile('org.springframework.security:spring-security-test')
 }

 dependencyManagement {
imports {
    mavenBom "org.springframework.cloud:spring-cloud-dependencies:${springCloudVersion}"
}
  }

在我的应用程序属性中

 spring.session.store-type=redis
 spring.redis.host=my aws redis end point
 spring.redis.password=my password
 spring.redis.port=6379

我正在按照这里的指南 https://docs.spring.io/spring-session/docs/current/reference/html5/guides/boot-redis.html#boot-how

Answer 1

您使用的 Spring Boot 和 Spring Session 版本不兼容。

Spring Boot 1.5 与 Spring Session 1.3 对齐，如 dependency versions appendix 中所示Spring Boot 的引用手册。 OTOH，Spring Boot 2.0 与 Spring Session 2.0 保持一致，可以看出 here .

您应该真正避免在构建脚本中使用显式依赖版本声明，并依赖 Spring Boot 提供的依赖管理，除非有充分的理由不这样做。
