Question

我正在尝试使用Tomcat 6.0部署Grails应用。当我使用与Grails打包的数据库时它工作正常。但是，当我使用PostgreSQL时，我收到状态404错误。

日志给我以下内容：

非常感谢任何建议。

这里要求的是datasource.config：

dataSource {
        pooled = true
        driverClassName = "org.postgresql.Driver"
}
hibernate {
    cache.use_second_level_cache=true
    cache.use_query_cache=true
    cache.provider_class = 'net.sf.ehcache.hibernate.EhCacheProvider'
}

environments {
    development {
        dataSource {
            dbCreate = "create-drop" // one of 'create', 'create-drop','update'
            url = "jdbc:postgresql:Test"
                        username = "postgres"
                        password = "highpoint"
        }
    }
    test {
            dataSource {
            dbCreate = "update"
            url = "jdbc:postgresql:Test"
                        username = "postgres"
                        password = "highpoint"
        }
    }
    production {
        dataSource {
            dbCreate = "create-drop"
            url = "jdbc:postgresql:Test"
                        username = "postgres"
                        password = "highpoint"
        }
    }
 }

这是buildconfig文件：

grails.project.class.dir = "target/classes"
grails.project.test.class.dir = "target/test-classes"
grails.project.test.reports.dir = "target/test-reports"
//grails.project.war.file = "target/${appName}-${appVersion}.war"
grails.project.dependency.resolution = {
    // inherit Grails' default dependencies
    inherits("global") {
        // uncomment to disable ehcache
        // excludes 'ehcache'
    }
    log "warn" // log level of Ivy resolver, either 'error', 'warn', 'info', 'debug' or 'verbose'
    repositories {
        grailsPlugins()
        grailsHome()
        grailsCentral()

        // uncomment the below to enable remote dependency resolution
        // from public Maven repositories
        //mavenLocal()
        //mavenCentral()
        //mavenRepo "http://snapshots.repository.codehaus.org"
        //mavenRepo "http://repository.codehaus.org"
        //mavenRepo "http://download.java.net/maven/2/"
        //mavenRepo "http://repository.jboss.com/maven2/"
    }
    dependencies {
        // specify dependencies here under either 'build', 'compile', 'runtime', 'test' or 'provided' scopes eg.

        // runtime 'mysql:mysql-connector-java:5.1.13'
    }
}

按照Oliver的建议更改数据源和配置文件后，得到以下结果：我不再得到404错误，但Tomcat现在挂起并且不显示网站。错误日志给出了以下错误：

Nov 18, 2011 1:03:01 PM org.apache.catalina.startup.HostConfig deployDirectory

Answer 1

您没有安装驱动程序。

dependencies {
    runtime 'postgresql:postgresql:9.0-801.jdbc4'
}

将buildconfig更改为，并且应该加载。

此外，jdbc网址应如下所示：

jdbc:postgresql://localhost:5432/grails

显然用你在postgresql中设置的内容替换端口和数据库名称。

根据更多信息进行编辑：

使用run-config或导出到GRAILS_OPTS来增加permgen。你根据你使用的IDE来做不同的事情，所以谷歌是你的朋友。如果你无法自己解决这个问题，那么无论如何都会是一个单独的问题，所以请随意接受这个问题作为回答:-)
