mongodb - 初始化应用程序时出错 : No datastore implementation specified Message: No datastore implementation specified

Question

我想在 MongoDB 中使用 Grails2.5 中的“ElasticSearch”插件。我的“BuildConfig.groovy”文件是:

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:5.1.29'
        // runtime 'org.postgresql:postgresql:9.3-1101-jdbc41'
        //runtime "org.elasticsearch:elasticsearch:0.90.3"
        //runtime "org.elasticsearch:elasticsearch-lang-groovy:1.5.0"

        test "org.grails:grails-datastore-test-support:1.0.2-grails-2.4"
    }

    plugins {
        // plugins for the build system only
        build ":tomcat:7.0.55.2" // or ":tomcat:8.0.20"

        // plugins for the compile step
        compile ":scaffolding:2.1.2"
        compile ':cache:1.1.8'
        compile ":asset-pipeline:2.1.5"
        compile ':mongodb:3.0.3'

        // plugins needed at runtime but not for compilation
        //runtime ":hibernate4:4.3.8.1" // or ":hibernate:3.6.10.18"
        runtime ":database-migration:1.4.0"
        runtime ":jquery:1.11.1"
        runtime ":elasticsearch:0.0.4.4"

        // Uncomment these to enable additional asset-pipeline capabilities
        //compile ":sass-asset-pipeline:1.9.0"
        //compile ":less-asset-pipeline:1.10.0"
        //compile ":coffee-asset-pipeline:1.8.0"
        //compile ":handlebars-asset-pipeline:1.3.0.3"
    }
}

我的“Config.groovy”文件也是:

// locations to search for config files that get merged into the main config;
// config files can be ConfigSlurper scripts, Java properties files, or classes
// in the classpath in ConfigSlurper format

// grails.config.locations = [ "classpath:${appName}-config.properties",

//                             "file:${userHome}/.grails/${appName}-config.groovy"]

// if (System.properties["${appName}.config.location"]) {
//    grails.config.locations << "file:" + System.properties["${appName}.config.location"]
// }

grails.project.groupId = appName // change this to alter the default package name and Maven publishing destination

// The ACCEPT header will not be used for content negotiation for user agents containing the following strings (defaults to the 4 major rendering engines)
grails.mime.disable.accept.header.userAgents = ['Gecko', 'WebKit', 'Presto', 'Trident']
grails.mime.types = [ // the first one is the default format
    all:           '*/*', // 'all' maps to '*' or the first available format in withFormat

Answer 1

我怀疑你必须改变这一行

elasticSearch.datastoreImpl="mongodbDatastore"

到

datastoreImpl="mongodbDatastore"

因为您已经嵌套在 elasticSearch 命名空间中。
