无法使Elasticsearch插件与Grails 3配合使用 [英] Can't Get Elasticsearch Plugin to Work with Grails 3

问题描述

我试图用Grails 3.1.9项目连接Elasticsearch插件（org.grails.plugins：elasticsearch：1.4.1'），但没有任何运气。

I've tried to hook up Elasticsearch plugin ('org.grails.plugins:elasticsearch:1.4.1') with a Grails 3.1.9 project without any luck.

我还在github中上传了一个简单的应用程序来演示该问题（ https://github.com/jackiebai/testEs ）

I've also uploaded a simple application in github to demonstrate the issue (https://github.com/jackiebai/testEs)

上面的示例测试应用只有一个域类，称为 Person ：

The above sample testing app only has 1 domain class called Person:

class Person {
    String name
    static searchable = true
    static constraints = {
    }
}

相应的服务类 PersonService 用于保存和索引Person数据：

The corresponding service class PersonService is used to save and index the Person data:

import grails.transaction.Transactional
@Transactional
class PersonService {
    def addPerson(Person person){
        person.save()
        person.index()
    }
    def addPerson(String name) {
        Person p = new Person(name:name)
        addPerson(p)
    }
}

我还添加了一个 BootStrap.groovy 中的许多行代码，以便在应用程序启动时将某些数据插入默认的休眠数据库中：

I've also added a couple of lines of code in the BootStrap.groovy so that some data will get inserted into the default hibernate db when the application starts:

class BootStrap {
    def personService
    def init = { servletContext ->
        personService.addPerson("Person One")
        personService.addPerson("John Smith")
    }
    def destroy = {
    }
}

开发环境的application.yml变量设置如下所示：
环境：
开发：
数据源：
dbCreate：create-drop
url：jdbc：h2：mem：devDb; MVCC = TRUE; LOCK_TIMEOUT = 10000; DB_CLOSE_ON_EXIT = FALSE
elasticSearch：
客户端：
模式：节点
transport.sniff：true
bulkIndexOnStartup：true
datastoreImpl：hibernateDatastore

The application.yml variable settings for the development environment look like below: environments: development: dataSource: dbCreate: create-drop url: jdbc:h2:mem:devDb;MVCC=TRUE;LOCK_TIMEOUT=10000;DB_CLOSE_ON_EXIT=FALSE elasticSearch: client: mode: node transport.sniff: true bulkIndexOnStartup: true datastoreImpl: hibernateDatastore

通过遵循插件用户指南（ http://noamt.github.io/elasticsearch- grails-plugin / docs / index.html ）

Additional dependencies and bootRun code block were included in the build.gradle by following the plugin user guide (http://noamt.github.io/elasticsearch-grails-plugin/docs/index.html)

dependencies {
    ...
    compile 'org.grails.plugins:elasticsearch:1.4.1'
    compile 'org.elasticsearch:elasticsearch:5.4.1'
    ...
}
bootRun{
    jvmArgs = ['-Des.path.home=/Users/myname/elasticsearch-5.4.1']
}

不幸的是，应用程序无法在我的osx 10.11.6，java 1.8.0_91环境下运行，并出现以下错误：

Unfortunately the application failed to run under my osx 10.11.6,java 1.8.0_91 environment with below errors:
