Question

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

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

上述示例测试应用程序只有一个名为 Person 的域名类：

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：

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)
    }
}

我还在 BootStrap.groovy 中添加了几行代码，以便在应用程序启动时将一些数据插入到默认的hibernate数据库中：

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：发展：数据源： dbCreate：create-drop url：jdbc：h2：mem：devDb; MVCC = TRUE; LOCK_TIMEOUT = 10000; DB_CLOSE_ON_EXIT = FALSE elasticSearch：客户： mode：节点 transport.sniff：是的 bulkIndexOnStartup：true datastoreImpl：hibernateDatastore

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

，build.gradle中包含其他依赖项和bootRun代码块

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，但错误如下：

Answer 1

根据您使用的文档使用v1.2.0

https://github.com/noamt/elasticsearch-grails-plugin

Answer 2

我认为版本1.4.1已被破坏。您可以使用Grails 3.3+尝试2.4.0.RC1，但是您需要向mapper-attachments添加依赖项并为Spring Boot指定elasticsearch.version：

ext['elasticsearch.version'] = '5.4.1'

dependencies {
    compile 'org.grails.plugins:elasticsearch:2.4.0.RC1'
    runtime 'org.elasticsearch.plugin:mapper-attachments:2.4.6'
}
