3 月，4 周 Questions & Answers

我正在测试Spring Boot 1.3.0。M3与ehcache发生冲突，出现了一些问题

启动应用程序时，控制台上出现以下异常：

我有一个电子缓存。我的类路径和EHCacheManager中的xml被实例化。 当我删除SpringBootStarter缓存和ehcache依赖项时，一切都开始正常。（但仅适用于ConcurrentMapCacheManager）

问题：

我是否需要使用spring boot starter缓存的velocity，或者是否有其他缺失或错误的内容


共 (3) 个答案

  1. # 1 楼答案

    使用最新版本的Spring Boot，您可以执行以下操作-

    @SpringBootApplication(exclude = VelocityAutoConfiguration.class)
  2. # 2 楼答案

    只有在类路径中存在以下两个类时，VelocityAutoConfiguration才会生效：

    @ConditionalOnClass({ VelocityEngine.class, VelocityEngineFactory.class })

    它们分别来自org.apache.velocity:velocity和org.springframework:spring-context-support

    您可以通过以下方式确定哪些依赖项正在通过传递方式添加到项目中：

    mvn dependency:tree

  3. # 3 楼答案

    我对spring security cas也有同样的问题，这取决于速度。您可以通过添加

    @EnableAutoConfiguration(exclude = VelocityAutoConfiguration.class)

    到spring boot应用程序主类
