java - grails 2.5.2 run-app 可以运行但不能运行

Question

我在尝试执行 grails run-war 时看到以下错误消息。它适用于 grails run-app。后来才知道不是只有grails有关系。即使我创建 war 并将其部署在 tomcat 上，我也会看到相同的错误消息。但不确定如何调试更多。看起来与 tomcat 默认 jar 有某种冲突。

Grails version: 2.5.2

Tomcat Version: `build ":tomcat:7.0.55.3"`

Answer 1

终于意识到 spring-boot-cli-1.3.1.RELEASE.jar jar 造成了这个麻烦。我认为这是作为以下依赖项的一部分下载的。

<dependency>
   <groupId>org.grails</groupId>
   <artifactId>gorm-hibernate4-spring-boot</artifactId>
   <version>5.0.8.RELEASE</version>
</dependency>

将上面更改为以下内容解决了问题。

<dependency>
   <groupId>org.grails</groupId>
   <artifactId>gorm-hibernate4-spring-boot</artifactId>
   <version>5.0.8.RELEASE</version>
   <scope>provided</scope>
</dependency>

我认为这个 jar 与 tomcat 启动过程有冲突。有关更多信息，请关注以下主题。
