Slor 条件查询提示:org.apache.http.ParseException: Invalid content type:

今天在编写Solr查询条件时，启动单元测试，solr 提示如下错误信息:

Caused by: org.apache.http.ParseException: Invalid content type:

报错代码片段：

SolrQuery query = new SolrQuery();

this.setQuery(query, localParam);

// solr请求
QueryResponse queryResponse = server.query(query);

public void setQuery(SolrQuery query, Map<String, Object> parameter){

造成问题原因:GET向solr传递参数的时候参数过长导致的。

解决办法一: GET请求替换为POST 请求

修改后的代码:

SolrQuery query = new SolrQuery();

this.setQuery(query, localParam);

// solr请求
QueryResponse queryResponse = server.query(query, METHOD.POST);

解决办法二:修改solr配置

配置文件位置：SOLRHOME/CORE_NAME/conf/solrconfig.xml

找到如下配置：

<maxBooleanClauses>1024</maxBooleanClauses>

1024 改为10240

其中，SOLRHOME为你的solr主目录，CORENAME为你的core的名称
