springboot+mybatis多数据源

由 会有一股神秘感。 提交于 2021-02-07 21:38:11
首先，既然是多数据源，那么我们就先看下数据源怎么配置的： javaconfig类似下面这样： MapperScan注解常用配置如下： basePackages：Base packages to scan for MyBatis interfaces，也就是mapper接口所在包名 annotationClass：This property specifies the annotation that the scanner will search for， 也就是只扫描指定包下的指定注解作为mapper，通常为org.apache.ibatis.annotations.Mapper markerInterface：This property specifies the parent that the scanner will search for，只扫描指定包下指定父接口的子接口作为mapper sqlSessionTemplateRef：指定这组mapper关联的sqlSessionTemplate sqlSessionFactoryRef：指定这组mapper关联的sqlSessionFactory 那么，问题来了，annotationClass，markerInterface都配置了或者都不配置会怎样？在org.mybatis.spring.annotation

java.lang.ClassNotFoundException: org.apache.commons.text.WordUtils

由 泪湿孤枕 提交于 2021-02-07 20:42:09
问题 I can't figure out why I'm getting a ClassNotFoundException here, since I have compiled with the appropriate jar file for WorkUtils, and the class WordUtils is clearly in the jar file. I compiled with javac -d bin -cp lib/commons-text-1.2.jar MyClass.java and run with java -cp bin MyClass Here is my java class: import org.apache.commons.text.WordUtils; class MyClass { public static void main(String[] args) { System.out.println(WordUtils.capitalize("sample text")); } } I get this error:

Nginx reverse proxy configuration

由 送分小仙女□ 提交于 2021-02-07 20:39:18
问题 I need nginx to reverse- proxy GET and POST requests of the form: /myapp/path/to/resource to: http://127.0.0.1:9090/path/to/resource I'm trying the following: location /myapp/(.*) { rewrite $1; proxy_pass http://127.0.0.1:9090; } but nginx is returning a HTTP 405 error [not allowed]. Any ideas on how to fix this ? Thanks. 回答1: You don't actually need to do a rewrite. You can achieve the same end with the following: location /myapp/ { proxy_pass http://127.0.0.1:9090/; } 来源： https:/

kafka集群管理工具kafka-manager部署安装

一、kafka-manager 简介 为了简化开发者和服务工程师维护Kafka集群的工作，yahoo构建了一个叫做Kafka管理器的基于Web工具，叫做 Kafka Manager。这个管理工具可以很容易地发现分布在集群中的哪些topic分布不均匀，或者是分区在整个集群分布不均匀的的情况。它支持管理多个集群、选择副本、副本重新分配以及创建Topic。同时，这个管理工具也是一个非常好的可以快速浏览这个集群的工具，有如下功能： 1.管理多个kafka集群 2.便捷的检查kafka集群状态(topics,brokers,备份分布情况,分区分布情况) 3.选择你要运行的副本 4.基于当前分区状况进行 5.可以选择topic配置并创建topic(0.8.1.1和0.8.2的配置不同) 6.删除topic(只支持0.8.2以上的版本并且要在broker配置中设置delete.topic.enable=true) 7.Topic list会指明哪些topic被删除（在0.8.2以上版本适用） 8.为已存在的topic增加分区 9.为已存在的topic更新配置 10.在多个topic上批量重分区 11.在多个topic上批量重分区(可选partition broker位置) kafka-manager 项目地址： https://github.com/yahoo/kafka-manager 二

URL Rewriting - Redirect With No File Extension

由 情到浓时终转凉″ 提交于 2021-02-07 19:45:57
问题 I am currently using the following rules in a .htaccess file: RewriteEngine on RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME}\.php -f RewriteRule ^(.*)$ $1.php This works well to ensure that /myfile.php works as well as just myfile (with no extension in the URL). It also handles querystrings with no problems, so myfile?var=foo also works. The problem is that these are registering in Google Analytics as being two separate files. So while myfile.php might be the third most
