grails 2.5.2运行应用程序但不能运行

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。后来我意识到它不仅与grails有关。即使我创建了war并在tomcat上部署它，我也看到了同样的错误信息。但不知道如何调试更多。看起来像一些与tomcat默认jar的冲突。

Grails version: 2.5.2 

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

Answer 1

终于实现spring-boot-cli-1.3.1.RELEASE.jar罐子造成这种麻烦。我认为下载哪个作为以下依赖项的一部分。

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

更改为以下解决了问题。

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

我觉得这个jar与tomcat的启动过程相冲突。有关更多信息，请遵循以下主题
