如何在Tomcat7中部署Grails 3.0.1 war文件？

ran*_*hip 11 grails tomcat

如何Grails 3.0.1在Tomcat7的非嵌入式版本中部署war文件？我得到的只是一个空白页面或404错误.我可以成功部署我的其他war文件,所以我知道这不是Tomcat的问题.我的版本和我采取的步骤如下:

Server version: Apache Tomcat/7.0.52 (Ubuntu)
Grails Version: 3.0.1
Groovy Version: 2.4.3
JVM Version: 1.7.0_80
Run Code Online (Sandbox Code Playgroud)

我怀疑这个问题与Spring框架或Gradle有关.我对它们中的任何一个都不是很熟悉,但我确实注意到3.0.1不再使用a web.xml而且不再有Config.groovy文件.以下网站详细介绍了如何在3.0.x中部署Grails项目.

http://grails.github.io/grails-doc/3.0.x/guide/deployment.html

  1. 我跑了grails run-app,它localhost:8080没有任何问题地部署到漂亮.

我不想使用嵌入式版本的Tomcat.我想将它部署到不同版本的Tomcat,这就是我遇到问题的地方.

  1. 我将Tomcat依赖项的范围更改为:
    • provided "org.springframework.boot:spring-boot-starter-tomcat"
  2. 我使用生成war文件 grails war
    • 添加website.war到/var/lib/tomcat7/webapps
    • 跑去sudo service tomcat7 restart重启tomcat
    • 检查是否website.war自动解压缩(确实如此)
    • 检查 localhost:9999/website

^这给了我一个空白的白页.

  1. 我删除了website.war它与相关的解压缩文件夹.
    • 检查 localhost:9999
    • 它成功地将我带到了默认的Tomcat屏幕
    • 签到经理应用程序
    • 部署website.war在经理应用程序上
    • 它给了我ok地位
    • 检查 localhost:9999/website

^这给我以下错误:

HTTP状态404 - /website,请求的资源不可用.

其他相关信息:

https://grails.github.io/grails-doc/3.0.x/guide/single.html:

"Grails 3.0不再需要web.xml.可以通过Spring完成自定义"

该BuildConfig.groovy文件也已更改.

旧位置:grails-app/conf/BuildConfig.groovy 新位置:build.gradle 说明:现在,在Gradle构建文件中定义构建时配置

  • 这表明在webapps文件夹中发起了一场战争.我已经尝试过了,但它没有用.

stackoverflow.com/questions/27557893/grails-app-deploy-in-tomcat-server-using-war-file-fails

  • 他问了一个非常相似的问题,但他正在使用不同版本的Grails
  • 标记的解决方案参考 Config.groovy
  • 但是Grails 3.0.1现在的构建时间配置Build.gradle
  • 我不知道他是否成功解决了这个问题.

stackoverflow.com/questions/23664421/cant-deploy-grails-war-file-in-tomcat-results-in-404

  • 解决方案需要更改Config.groovy,在Grails 3.0.1项目中不再可用

编辑:

解压缩website.war文件夹时,catalina.out日志文件会显示:

为了提供更全面的答案,使用David Gonzalez Maline提供的链接,Graeme引用了GitHub中的文档提交.

请注意,默认情况下,Grails将在WAR文件中包含一个可嵌入的Tomcat版本,以便它可以运行(请参阅上一节),如果部署到不同版本的Tomcat,这可能会导致问题.如果您不打算使用嵌入式容器,则应在部署到生产容器之前将Tomcat依赖关系的范围更改为@ provided @build.gradle:

provided "org.springframework.boot:spring-boot-starter-tomcat"

来源(强调我的)

简而言之,如果将其保留在默认compile范围内,它将包括两个不同版本的Tomcat,Tomcat 7(您正在部署)和Tomcat 8(由其提供spring-boot-starter-tomcat).

答案在这里：

https://jira.grails.org/browse/GRAILS-12105

您需要声明依赖关系org.springframework.boot:spring-boot-starter-tomcat

中规定build.gradle。
