Spring Data / Spring Boot循环依赖问题?

标签: spring spring-boot spring-data spring-data-jpa

我在Spring Boot应用程序中遇到了一个关于Spring Data JPA存储库的问题。

我有几个存储库接口,只能通过@Service和mockmvc集成测试直接使用。

服务本身用于@Controller s以及Spring Converter类。

一切正常,直到我对我的包结构进行了一些重构。

似乎无法找到datassource的密码属性。 让我保证我的application.yml没有变化,属性就在那里。

注意我看到类似的错误,例如数据源的网址和用户名属性。

在日志记录中我也看到:

Caused by: java.lang.IllegalStateException: Cannot load driver class: org.hsqldb.jdbc._jdbcdriver
    at org.springframework.util.Assert.state(Assert.java:385)
    at org.springframework.boot.autoconfigure.jdbc.DataSourceProperties.getDriverClassName(rceProperties.java:122)
    at org.springframework.boot.autoconfigure.jdbc.DataSourceProperties.getUsername(DataSourceProperties.java:165)
    ... 145 common frames omitted

但当然在我的application.yml中我配置了org.hsqldb.jdbc.JDBCDriver

有趣的是,这引起了我对其余错误的关注:

Related cause: org.springframework.beans.factory.BeanCurrentlyInCreationException: 
Error creating bean with name 'costCenterInputConverter': 
Requested bean is currently in creation: Is there an unresolvable circular reference?

CostCenterInputConverter似乎是问题的根源。 它依赖于服务,而服务依赖于Spring Data Repository类。没什么特别的。

这个类也是我重构中移动的类之一。 现在奇怪的是,当我把这个类放回原来的包(nl.myapp.web.input)时,一切都运行正常。当我再次移动到新位置(nl.myapp.web.converter)时,会发生同样的错误。

请注意,我有多个这些转换器类,其中一些具有自动服务。如果由于上述错误而失败,则将具有服务依赖性的任何转换器移动到新位置。没有服务依赖性的转换器可以毫无问题地移动。

我真的对这个问题感到不满。

它似乎与Spring Data有关,或者可能是因为Spring Boot执行了一些Spring Data自动配置?但无论如何Spring容器应该能够处理这个问题;从来没有看到移动类到其他包会像这样破坏。

我可以轻松地将课程移回原始课程但这感觉很糟糕;我想知道这里发生了什么。

更新

是的,转换器是通过组件扫描拾取的。但这适用于新旧位置。 基本上我的项目结构是:

+-- domain
+-- respository
+-- service
+-- web
    +-- alpha --> converter in this package fails
    +-- beta --> converter in this package fails
    +-- charlie --> converter in this package fails
    +-- controller
    +-- converter --> converter in this package fails
    +-- delta--> converter in this package gives no problem
    +-- echo --> converter in this package gives no problem
    +-- foxtrot --> converter in this package gives no problem
    +-- golf --> converter in this package gives no problem
    +-- hotel --> converter in this package gives no problem
    +-- india --> converter in this package gives no problem
    +-- input
    +-- resource

它似乎是包的名称(订单?)。 也许其中一个Boot人知道Boot是否正在做一些特别的事情。

答案 0 :(得分:2)

似乎与此错误报告有关:https://github.com/spring-projects/spring-boot/issues/2669#issuecomment-82410426 将进一步调查Boot 1.3行。
