使用 JDBC 与 Grails3 集成 Spring Session 时无法获取 SessionRepository

Question

我无法使用

Spring Session

将

Grails-3.3.15

与

JDBC

应用程序集成，以在

HttpSession

数据库中保留

PostgreSQL

。我在应用程序启动时得到

BeanCreationException

。

背景：

我在这里参考了官方指南解释了Redis的实施（找不到JDBC的相关指南）并做了下面提到的JDBC实施的更改：

1. build.gradle：

compile "org.springframework.session:spring-session-jdbc"
compile 'org.springframework.boot:spring-boot-starter-data-jpa'

2. application.groovy：

spring.datasource.url=System.getenv("DB_URL")
spring.datasource.username=System.getenv("DB_USERNAME")
spring.datasource.password=System.getenv("DB_PASSWORD")

3. 应用程序.yml

spring:
  session:
    store-type: "jdbc"
    table-name: "SPRING_SESSION"

问题：

这里是异常的堆栈跟踪：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.boot.autoconfigure.session.SessionAutoConfiguration$SessionRepositoryValidator': Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: No session repository could be auto-configured, check your configuration (session store type is 'jdbc')

故障排除：

经过进一步调试，我发现在

checkSessionRepository()

的

org.springframework.boot.autoconfigure.session.SessionRepositoryValidator

中

sessionRepositoryProvider.getIfAvailable()

返回

null

并且该方法抛出

IllegalArgumentException

.

似乎

SessionRepository

没有配置。 有什么我想念的吗？ 任何帮助将不胜感激。
