Question

我正在运行grails脚本来从grails应用程序加载bean，但是，似乎我有一个依赖性问题。这是我的代码：

import grails.spring.BeanBuilder
import org.springframework.context.ApplicationContext

target(main: "Script to load location information into Solr") {

println "Hello script"
def bb = new BeanBuilder()
ApplicationContext appContext = bb.createApplicationContext()
def service = appContext.getBean("solrjService")   
}

setDefaultTarget(main)

当我执行脚本时，我得到以下stacktrace：

main:
Hello script

任何想法??

感谢您的时间

Answer 1

如果你读了调用堆栈，那显然是SLF4J的一个问题。

请参阅http://slf4j.org/faq.html#IllegalAccessError

看起来你可能会混合使用SLF4J罐子的版本，并且会发生冲突。

但是，当然，Burt是正确的 - 一旦你超越了这个，你会发现你已经初始化了BeanBuilder的ApplicationContext而没有bean。

我必须包含目标_GrailsBootstrap才能加载我的bean http://grails.org/doc/latest/guide/commandLine.html#creatingGantScripts

includeTargets << grailsScript("_GrailsBootstrap")

target ('default': "Load Location Information to Solr Server") {

depends(configureProxy, packageApp, classpath, loadApp, configureApp)
def service = appCtx.getBean('solrjService')
println service.getLocationSuggestion("Barcelona")

}

我按照他的方式运行脚本（这就是我遇到类路径问题的原因）

grails run-script scripts/Myscript.groovy

然后现在，我这样运行

grails Myscript.groovy

我没有任何类路径问题：D

感谢您的帮助
