Grails：MySQL 和 mongoDB 一起使用

Question

我是 GRAILS 的新手。我正在尝试在一个网络应用程序中使用 MySQL 和 MongoDB。 有人可以快速查看我的 BuildConfig.groovy 和 datasource.groovy 并建议我正确的前进方式。

buildconfig.groovy

grails.servlet.version = "3.0" // Change depending on target container compliance (2.5 or 3.0)
grails.project.class.dir = "target/classes"
grails.project.test.class.dir = "target/test-classes"
grails.project.test.reports.dir = "target/test-reports"
grails.project.work.dir = "target/work"
grails.project.target.level = 1.6
grails.project.source.level = 1.6
//grails.project.war.file = "target/${appName}-${appVersion}.war"

grails.project.fork = [
// configure settings for compilation JVM, note that if you alter the Groovy version     forked compilation is required
//  compile: [maxMemory: 256, minMemory: 64, debug: false, maxPerm: 256, daemon:true],

// configure settings for the test-app JVM, uses the daemon by default
test: [maxMemory: 768, minMemory: 64, debug: false, maxPerm: 256, daemon:true],
// configure settings for the run-app JVM
run: [maxMemory: 768, minMemory: 64, debug: false, maxPerm: 256, forkReserve:false],
// configure settings for the run-war JVM
war: [maxMemory: 768, minMemory: 64, debug: false, maxPerm: 256, forkReserve:false],
// configure settings for the Console UI JVM
console: [maxMemory: 768, minMemory: 64, debug: false, maxPerm: 256]
]

grails.project.dependency.resolver = "maven" // or ivy
grails.project.dependency.resolution = {
// inherit Grails' default dependencies
inherits("global") {
    // specify dependency exclusions here; for example, uncomment this to disable ehcache:
    // excludes 'ehcache'
}
log "error" // log level of Ivy resolver, either 'error', 'warn', 'info', 'debug' or 'verbose'
checksums true // Whether to verify checksums on resolve
legacyResolve false // whether to do a secondary resolve on plugin installation, not advised and here for backwards compatibility

repositories {
    inherits true // Whether to inherit repository definitions from plugins

    grailsPlugins()
    grailsHome()
    mavenLocal()
    grailsCentral()
    mavenCentral()
    // uncomment these (or add new ones) to enable remote dependency resolution from public Maven repositories
    //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 e.g.
     runtime 'mysql:mysql-connector-java:5.1.27'
    // runtime 'org.postgresql:postgresql:9.3-1100-jdbc41'
     compile 'org.grails:grails-datastore-gorm:3.0.4.RELEASE'
     compile 'org.grails:grails-datastore-core:3.0.4.RELEASE'
     test 'org.grails:grails-datastore-simple:3.0.4.RELEASE'
}

plugins {
    // plugins for the build system only
    build ":tomcat:7.0.52.1"

    // plugins for the compile step
    compile ":scaffolding:2.0.2"
    compile ':cache:1.1.1'
    //compile ":datasources:0.5"

    // plugins needed at runtime but not for compilation
    runtime ":hibernate:3.6.10.9" // or ":hibernate4:4.3.4"
    runtime ":database-migration:1.3.8"
    runtime ":jquery:1.11.0.2"
    runtime ":resources:1.2.7"
    // Uncomment these (or add new ones) to enable additional resources capabilities
    //runtime ":zipped-resources:1.0.1"
    //runtime ":cached-resources:1.1"
    //runtime ":yui-minify-resources:0.1.5"
    compile ":mongodb:2.0.1"
    // An alternative to the default resources plugin is the asset-pipeline plugin
    //compile ":asset-pipeline:1.6.1"

    // Uncomment these to enable additional asset-pipeline capabilities
    //compile ":sass-asset-pipeline:1.5.5"
    //compile ":less-asset-pipeline:1.5.3"
    //compile ":coffee-asset-pipeline:1.5.0"
    //compile ":handlebars-asset-pipeline:1.3.0.1"
}
}

DataSource.groovy

dataSource {
pooled = true
jmxExport = true
driverClassName = "com.mysql.jdbc.Driver"
dialect = "org.hibernate.dialect.MySQL5InnoDBDialect"
username = "root"
password = "root"
}
grails {
mongo {
    host = "localhost"
    port = 27017
    //replicaSet = [ "localhost:27017", "localhost:27018"]
    databaseName = "test"
}
 }
hibernate {
cache.use_second_level_cache = true
cache.use_query_cache = false
cache.region.factory_class = 'net.sf.ehcache.hibernate.EhCacheRegionFactory' //     Hibernate 3
//    cache.region.factory_class = 'org.hibernate.cache.ehcache.EhCacheRegionFactory' // Hibernate 4
singleSession = true // configure OSIV singleSession mode
}

// environment specific settings
 environments {
development {
    dataSource {
        dbCreate = "create-drop" // one of 'create', 'create-drop', 'update', 'validate', ''
        url = "jdbc:mysql://localhost:3306/web_store"
        username = "root"
        password = "root"
    }

}
test {
    dataSource {
        dbCreate = "update"
        url = "jdbc:mysql://localhost:3306/web_store"
        username = "root"
        password = "root"
    }

}
production {
    dataSource {
        dbCreate = "update"
        url = "jdbc:mysql://localhost:3306/web_store"
        username = "root"
        password = "root"

    }

}
   }

这是我得到的错误：

Answer 1

萨加尔，

我发现这实际上是 mongodb<any version> 和 hibernate-3.6.10.9 的问题 一起玩得不好。如果你降级到:hibernate:3.6.10.8，你应该很高兴，至少这对我有用。

我试图为此投入一张 jira 票，但我得到了 500 的...

Answer 2

我以前也有同样的问题。我通过卸载hibernate解决了它。

Hibernate 和 mongodb 在 grails 中并没有齐头并进，所以需要卸载 hibernate 才能使用 mongodb

转到 conf/buildConfig.groovy 注释掉写着

的行

"运行时":hibernate:3.6.10.9""

它应该可以正常工作
