无法解析类grails.plugin.multitenant.core.util.TenantUtils - Grails 2.3.11

Question

我在旧的grails中有一个项目，我试图将它升级到新版本的grails2.3.11，但是这个项目在导入多租户插件时出现了错误，这是一个错误的例子：

D:\GitHub\~\grails-app\conf\BootStrap.groovy: 3: unable to
 resolve class grails.plugin.multitenant.core.util.TenantUtils
 @ line 3, column 1.
   import grails.plugin.multitenant.core.util.TenantUtils
   ^

这是我的buildConfig：

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'
        // https://mvnrepository.com/artifact/org.gagravarr/vorbis-java-core
        compile group: 'org.gagravarr', name: 'vorbis-java-core', version: '0.8'

    }
    plugins {
        //build ":tomcat:7.0.52.1"

        compile ":mail:1.0.1"
        compile ":fields:1.4"

        compile ":burning-image:0.5.1"
        compile ":twitter-bootstrap:2.3.2"
        compile ":spring-security-core:2.0-RC4"
        compile ":spring-security-rest:1.4.0.RC5"/*, {
            excludes: 'spring-security-core'
        }*/

        // events to implement app hooks
        compile ":platform-core:1.0.RC6"

        // Para fazer upload de imagens
        compile ":attachmentable:0.3.0"

        // calendários para campos do tipo Date
        compile ":calendar:1.2.1"

        // exportar dados para Excel
        compile ":excel-export:0.1.9", {
            excludes: 'xerces'
        }

        // Jasper Reports
        compile ":jasper:1.11.0"

        // Export CSV
        compile ":csv:0.3.1"

        // Tests
        test ":cucumber:0.6.2"

        // Profiling
        compile ":profiler:0.5"

        //webservice SOAP
        compile ":cxf:1.1.4"
        compile ":cxf-client:2.0.3"

        //cron job
        compile ":quartz:1.0.2"

        compile ":ws-client:1.0"
        compile ":multi-tenant-single-db:0.8.3"

        //compile ":falcone-util:1.0"
    }
}

有人知道如何解决这个错误吗？或者，我需要在buildconfig中修改什么来解决这个问题，也许是一个更新的插件？

编辑

似乎可行的解决方案是修改代码，使其与多租户-单db: 0.8.3兼容，然后接受导入，这将产生冲突，但我从代码中摘录了以下内容：

class AssetController extends coss.BaseController {
  def restCreate = {
     TenantUtils.doWithTenant(1) {
            try {
                def json = JSON.parse(text)
                Asset asset = new Asset()
                ...
             } catch (Exception e) {
                log.error (e)
                render(status:500, text:e.getMessage())
             }
        }
    }
}

如何重写这一行TenantUtils.doWithTenant (1)

Answer 1

D:\GitHub~\grails-app\conf\BootStrap.groovy: 3:无法解析类grails.plugin.multitenant.core.util.TenantUtils @第3行，第1列导入grails.plugin.multitenant.core.util.TenantUtils ^

您的代码使用TenantUtils类，它在multi-tenant-single-db:0.8.3 where中不可用，TenantUtils类在这个插件中在compile "org.grails.plugins:multi-tenant-core:1.0.3"中可用。

但是在研究了这个插件页面之后，它看起来像是“这个插件与Grails2.x不兼容，您可能想看看http://grails.org/plugin/multi-tenant-single-db。”

所以应该尝试compile "org.grails.plugins:multi-tenant-core:1.0.3"这个插件，或者根据multi-tenant-single-db:0.8.3这个插件文档修改代码。

希望这能帮到你。
