Question

记录

在我的项目中，我有大约50个JpaRepositories。其中大多数都在主要的Web应用程序WAR中。一些是在6个外部JAR中编译成主要的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 Repositories创建Spring bean会占用我的机器 20秒。我有一个不那么老的i5和SSD。我有Spring 4.2和Spring Data JPA 1.9.4。

问题

这太长了。 任何人都知道如何加速Spring Data JPA存储库的bean创建或者查找哪些错误？

其他信息

我按如下方式配置了Spring Data JPA：

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

以下是Wildfly 8.2.0中的日志：

Answer 1

通过将Spring Data JPA从1.9.4升级到1.11.10解决了这个问题。此特定部分现在在3而不是52秒内执行。
