当我运行spring boot应用程序时,我得到以下错误：

应用程序启动失败

描述：

jar:file:/C:/Users/aoutir/.m2/repository/org/springframework/data/spring-data-redis/2.0.10.RELEASE/spring-data-redis-2.0.10.RELEASE.jar!/org/springframework/data/redis/connection/RedisConnection.class

我花了一整天的时间来解决这个完全相同的问题。并且经过一整天的研发，找到了解决方案。

dependencies {
implementation('org.springframework.boot:spring-boot-starter-data-jpa')
implementation('org.springframework.boot:spring-boot-starter-data-rest')
implementation('org.springframework.boot:spring-boot-starter-web')
implementation('org.springframework.boot:spring-boot-starter-security')
implementation('org.springframework.boot:spring-boot-starter-data-redis')
implementation('org.springframework.session:spring-session-data-redis')

runtimeOnly('org.springframework.boot:spring-boot-devtools')
testImplementation('org.springframework.boot:spring-boot-starter-test')
runtimeOnly('org.flywaydb:flyway-core')
runtimeOnly('com.h2database:h2')


// runtimeOnly('mysql:mysql-connector-java')

}

使用'spring-boot-starter-data-redis'和'spring-session-data-redis'。删除lettuse依赖项，因为它包含在spring-boot-starter-data-redis中作为依赖项。
