【solr专题之三】Solr常见异常

1、RemoteSolrException: Expected mime type application/octet-stream but got text/html

现象：

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.
Exception in thread "main" org.apache.solr.client.solrj.impl.HttpSolrServer$RemoteSolrException:Expected mime type application/octet-stream but got text/html.

分析：

由于各种错误导致了solr返回一个错误页面，而不是index成功的结果，因此出现以上异常。

其中上述html代码格式化后呈现：

HTTP Status 405 - HTTP method POST is not supported by this URL

---

type Status report

message HTTP method POST is not supported by this URL

description The specified HTTP method is not allowed for the requested resource.

解决方法：

在使用Tomcat部署Solr后，Collection1的地址为：http://ip:8080/solr/#/collection1，但使用SolrJ进行索引的时候，应该使用http://ip:8080/solr/collection1，即无中间的#号。

即正确代码为：

String serverUrl = (args != null && args.length > 0) ? args[0]
				: "http://ip:8080/solr/collection1";

错误代码为：

String serverUrl = (args != null && args.length > 0) ? args[0]
				: "http://ip:8080/solr/#/collection1";

错误代码将导致上述错误。
