java Elasticsearch 7.8和Magnolia 6.2。十、

3 月 Questions & Answers

我想使用最新的elasticsearch版本（7.8.0）和最新的Mgnl（CE）版本（目前为6.2.2）。在一些较老的项目中，他们经常使用弹性版本<；3.6对于所有api调用（如搜索/索引查询），它们使用Elastic的旧传输客户端。该客户机将被elastic的v8删除，并将被elastic的其余高级客户机Api替换

在我的测试中，我通过mvn原型生成使用了一个空白的mgnl 6.2.2，并使用一个虚拟页面和虚拟组件从mgnl设置了一个简单的模块。为了测试结果，我修改了该虚拟对象，将以下代码段作为组件模型调用

我的模型：

package com.test.model;

import javax.jcr.Node;

import org.elasticsearch.action.search.SearchRequest;
import org.elasticsearch.search.builder.SearchSourceBuilder;

import info.magnolia.rendering.model.RenderingModel;
import info.magnolia.rendering.model.RenderingModelImpl;
import info.magnolia.rendering.template.TemplateDefinition;

public class TestModel extends RenderingModelImpl<TemplateDefinition>{

    public TestModel(Node content, TemplateDefinition definition, RenderingModel<?> parent) {
        super(content, definition, parent);
    }

    public void init( ) {
        SearchRequest test = new SearchRequest();
        SearchSourceBuilder testSource = new SearchSourceBuilder();
        test.source(testSource);
        System.out.println("test done");
    }
}

以下是我的pom：

如果我尝试使用SearchSourceBuilder设置一个简单的SearchRequest，就像在TestModel中编写的那样，我会遇到以下异常：

在阅读了一些论坛后，我注意到如果lucene core有不同的版本，就会出现这种情况，因此我找出了哪些版本提供了：

mvn dependency:tree -Dverbose -Dincludes=org.apache.lucene

并得到如下结果：

如上所示，依赖项mgnl核心包含lucene核心v3。6来自jackrabbit core 2.20.0

如果我试图排除lucene v3。6且仅包括elasticsearch v7中的一个。8在上述我的测试模块中进行以下pom更改：

将发生以下例外情况：

在阅读了一些线程之后，我注意到这是由于带有jackrabbit@h2db:jackrabbit-bundle-h2-search的mgnl repo conf的标准配置造成的。xml，用于设置使用jackrabbit的searchindex@org的jcr存储库的searchindex。阿帕奇。大野兔。果心查询卢森。搜索索引

我花了很多时间在不禁用Searchindex的情况下修复它。有人知道如何解决这个问题来运行magnolia 6.2吗。x与Elastic的新Rest高级客户端

问候这么久，希望任何人都能帮忙：）

注意：对于原型生成@example，我使用以下命令进行设置：

mvn org.apache.maven.plugins:maven-archetype-plugin:2.4:generate -DarchetypeCatalog=https://nexus.magnolia-cms.com/content/groups/public/
