我想使用 mongodb、grails 和 elasticsearch 进行简单的搜索。但是我发现了这个问题，无法理解如何实现解决方案。

这是我的域类

package hellokitty
class Person {
    String name
    static mapWith = "mongo"

        static searchable = {
        only = 'name'
    }

    static constraints = {
    }
}

这是我的build.gradle文件

buildscript {
    ext {
        grailsVersion = '3.3.2'
        gormVersion = '6.1.8.RELEASE'
        elasticsearchVersion = '5.4.1'
        elasticsearchAttachmentsVersion = '5.4.1'
    }
    repositories {
        mavenLocal()
        maven { url "https://repo.grails.org/grails/core" }
    }
    dependencies {
        classpath "org.grails:grails-gradle-plugin:$grailsVersion"

Action:

Consider marking one of the beans as @Primary, updating the consumer to accept multiple beans, or using @Qualifier to identify the bean that should be consumed

任何人都可以给我任何建议吗？？谢谢

最佳答案

其实我也遇到了同样的问题，所以我创建了一个 issue 并由 grails 团队修复。

https://github.com/puneetbehl/elasticsearch-grails-plugin/issues/26

因此，只需将您的 elasticsearch 版本更新为 2.4.2 或替换为以下依赖项即可。

编译“org.grails.plugins:elasticsearch:2.4.2”。

感谢 Puneet Behl 修复并将此修复程序引入 2.4.2 版本。
