[schema.xml] fieldType "pint" 的 SolrException 插件初始化失败：加载错误 class 'solr.IntField'

Question

我遇到了这个错误

collection1: org.apache.solr.common.SolrException:org.apache.solr.common.SolrException: Could not load conf for core collection1: Plugin init failure for [schema.xml] fieldType "pint": Error loading class 'solr.IntField'.

当我尝试将集合 1 (solr 4.5) 架构导入 solr 5.1 时。

我只从不同的机器复制集合 1 where solr 4.5 运行并粘贴到这里 /solr/server/solr/collection1 where solr 5.1 运行然后重新启动 solr。对不起，我是初学者，对 solr 了解不多，请遵循一些教程。

Answer 1

我认为在您早期版本的 schema.xml 中，您的字段类型为 pint 现在在当前版本中它不受支持，因为我没有在 schema.xml 中看到 fieldType（在我下载 Solr.5.1.0 时的默认版本中）。

Replace/Remove 它和错误将得到纠正。

这个fieldType在之前的版本中就有（我用的是3.4）

<fieldType name="pint" class="solr.IntField" omitNorms="true"/>

在当前的5.1.0中我没有看到这个字段类型。

或者

您应该将 solr.IntField 替换为 solr.TrieIntField

Answer 2

您应该将 solr.IntField 替换为 solr.TrieIntField

solr.IntField 的文档说：

Deprecated. this class will be removed in 5.0 - use TrieIntField instead
