spring - Grails MongoDB 无法在 Tomcat 上运行应用程序

标签 spring mongodb tomcat grails

使用 Grails 2.3.8 和 MongoDB 插件 3.0.3。我的 MongoDB 数据库由 MongoLab 托管。当我在本地启动应用程序时，没有任何问题。

但是，当创建 WAR 文件然后将其托管在 Tomcat 服务器上时，会出现以下错误:

这是我的构建配置:

这是数据源:

environments {
    development {
        grails {
            mongo {
                host = "ds059682.mongolab.com"
                port = 59682
                username = "xxx"
                password="yyy"
                databaseName = "sacramento"
            }
        }
    }
    test {
        grails {
            mongo {
                host = "ds059682.mongolab.com"
                port = 59682
                username = "xxx"
                password="yyy"
                databaseName = "sacramento"
            }
        }
    }
    production {
        grails {
            mongo {
                // based on: cloudbees:123@paulo.mongohq.com:10044/456
                         host = "ds059682.mongolab.com"
                port = 59682
                username = "xxx"
                password="yyy"
                databaseName = "sacramento"
            }
        }
    }
}

我该如何解决这个问题？

最佳答案

您的应用程序似乎没有运行，因为您的 Tomcat 实例不包含 javax.servlet.AsyncContext 类，导致:

java.lang.ClassNotFoundException: javax.servlet.AsyncContext

该类在 Servlet 3.0 中引入，它是 Java EE 的一部分6. Servlet 2.5 是 Java EE 5 的一部分。您需要升级到 Tomcat 7这是一个 Servlet 3.0 容器。

  • Tomcat 7.X 包含 servelet 3.0
  • Tomcat 6.X 包含 servelet 2.5
