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: 
        at org.apache.http.entity.ContentType.parse(ContentType.java:233)
        at org.apache.solr.client.solrj.impl.HttpSolrServer.executeMethod(HttpSolrServer.java:496)

        at org.apache.solr.client.solrj.request.QueryRequest.process(QueryRequest.java:91)
        ... 90 more

报错代码片段：

SolrQuery query = new SolrQuery();
    
    this.setQuery(query, localParam);
    
    // solr请求
    QueryResponse queryResponse = server.query(query);

    		String text = (String) parameter.get("text");

    			query.setQuery("*:*");
    		} else {

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：

1024 改为10240

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