根据引用中的描述，出现"java.net.ConnectException: Connection refused: connect"的错误可能是由于数据库配置错误导致的。在该引用中，作者提到他将数据库所在服务器的IP地址写错了。这可能意味着应用程序无法连接到数据库服务器，从而引发了连接拒绝错误。另外，引用中提到，如果服务器中允许的最大进程数设置得较低，也可能导致连接被拒绝的错误。可以通过使用ulimit命令来检查和调整服务器允许的最大进程数。综上所述，如果出现"java.net.ConnectException: Connection refused: connect"错误，首先需要检查数据库配置是否正确，确保数据库服务器的IP地址和端口号正确，并且应用程序能够访问到该服务器。其次，还可以尝试检查服务器中允许的最大进程数，确保其足够高以支持应用程序的连接请求。<span class="em">1</span><span class="em">2</span> #### 引用[.reference_title] - *1* *2* [解决： java.net.ConnectException: Connection refused: connect](https://blog.csdn.net/u011314442/article/details/80926682)[target="_blank" data-report-click={"spm":"1018.2226.3001.9630","extra":{"utm_source":"vip_chatgpt_common_search_pc_result","utm_medium":"distribute.pc_search_result.none-task-cask-2~all~insert_cask~default-1-null.142^v92^chatsearchT0_1"}}] [.reference_item style="max-width: 100%"] [ .reference_list ]
