Spring Data JPA-缓慢为存储库创建bean

Question

历史

在我的项目中，我大约有50个JpaRepository。 它们中的大多数都位于主Web应用程序WAR中。 在6个外部JAR中有一些被编译为主要WAR。 我的应用服务器是Wildfly 8.2.0 Final。 我今天在日志中发现，从JPA存储库创建Spring Bean占用我的计算机20秒钟 。 我有一个不太旧的i5和一个SSD。 我有Spring 4.2和Spring Data JPA 1.9.4。

题

这太长了。 任何人都知道如何加快Spring Data JPA信息库的bean创建速度，或者在寻找什么错误时会遇到什么问题？

附加信息

我将Spring Data JPA配置如下：

@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(basePackages = {"pl.company"}, entityManagerFactoryRef = "myEmf")
@ComponentScan(basePackages = {"pl.company"})
public class PersistenceJPAConfig { 

以下是Wildfly 8.2.0的日志：

重复的片段耗时很长：

Answer 1

通过将Spring Data JPA从1.9.4升级到1.11.10来解决此问题。 现在，此特定部分将在3秒内执行，而不是52秒。
