Regardless of the persistence technology, the database must be accessed through a data connection, and in spring, the data connection is obtained through the data source. In previous applications, data sources are typically provided by Web application servers. In spring, you

Spring Boot integrates mybatis with multiple data sources. springmybatisPreface This tutorial is applicable to practical scenarios. You can simply add the copy code to your project for simple repair, modification, and usage. springboot and mybatis are not described here, if you want to learn more, you can leave a message for me and continue to pay attention to it. I will update it later. (For the code in th

practical application, we can see that there are several problems in connecting to the database using this method. The first is security. Because the program code contains the user name and password, if others can get bytecode, they can get the user name and password through The Decompilation tool. The second is code portability. If you want to change the name or user name of the connected database, the programmer must modify the source program and then send the modified program to the user. Th

From: http://www.javaeye.com/topic/931843 Implement myibatis dynamic SQL cross-database processingSpring dynamically configures multiple data sources, that is, splitting data in large applications and managing multiple database instances, which can effectively improve the horizontal scalability of the system. This solution is different from the common single

As business changes/requirements change, Java EE applications are forced to connect multiple data sources for business processing.How do you dynamically switch data sources in the most elegant/concise way without affecting the original project structure?This article has once added the

When developing a database-based application system, you must configure the data source in the project to connect to the database for database operations. The methods for configuring data sources for different databases are basically the same. The difference is that the JDBC driver classes and connection URLs of different databases and the corresponding database

When we develop a project, we may encounter the need to read and write multiple databases, and then we have to configure multiple data sources in the project. In the development of Java project, the most commonly used data operation framework is Mybatis, and the development framework is basically used springboot. And Druid claims to be the best database connectio

In the previous article we introduced the SOLRJ tool, in this article we introduced the SOLR data source. We use SOLR as the server for Full-text indexing, then we have to provide a data source for SOLR, and the small-format SOLR server summarizes three sources of data: Using commands to provide a

Due to historical reasons, many enterprises have multiple database platforms at the same time, and each database platform runs one or more related applications. As the business of an organization continues to expand, how can we quickly and effectively integrate the data distributed on different database platforms within the Organization without affecting the operation of existing applications, it is a problem that troubles CIOs. The existing solutions

With spring data source routing, it seems that there is no way to add data sources directly, but only with reflection.Add user data source in spring Security userdetailservice.loaduserbyusername when user login is successful/* * * Add user data source

Keywords: merge ObservableObjectiveIn Rxjava, it is a common operation to handle multiple observables at the same time. The following is a simple analysis of the next few combinations of the operators of the class.If you don't want to see the operator's introduction, you can skip to the actual combat section of the project.MergeIn the asynchronous world often creates such scenes, we have multiple sources but want only one result: multi-input, single o
