Use Spring Boot to configure dynamic data sources to access multiple databases. I wrote a blog titled Spring + Mybatis + Mysql to build a distributed database access framework. It describes how to configure dynamic data sources through Spring + Mybatis to access multiple databases. However, the previous solution has so

Spring applications are often deployed to Java EE application servers, such as Webshpere,jboss,resin or web containers such as Tomcat, which allow you to configure data sources to be fetched through Jndi. Often encountered in the project configuration data source, according to the work of learning and book learning, now summed up, is a bit of their own experience

There are many friends, especially beginners, who do not know much about the concepts of heterogeneous databases, heterogeneous data sources, and distributed databases. Sometimes they mix the three concepts, so the author has learned some materials, and sort them out. Hope to help friends. Heterogeneous Databases:HDB Heterogeneous Database The heterogeneous database system isCollection of related multi

compensation mechanismFor those with high performance requirements, but not high consistency requirements of the system, often not demanding system real-time consistency, as long as the final consistency within an allowable time period, which makes the transaction compensation mechanism a feasible solution. The transaction compensation mechanism is initially proposed in the process of "long transaction", but it is very useful for the distributed system to ensure the consistency. In general, unl

Spring + Mybatis: How to dynamically switch data sources. springmybatis The functional requirement is that the company wants to build a big operating platform: 1. The operating platform has its own database to maintain basic functions such as users, roles, menus, parts, and permissions. 2. The operating platform also needs to provide background operations for different services (service A and service B). da

contents and settings of all XML document data sources are placed in the params parameter. It defines 3 parameters that need to be passed to the report template: 1. In jasperreports, parameters are organized through a map collection, and in the example program (3), a variable named title is passed to the report template with the value "data source from XML

Talking about multi-data sources, generally to solve those problems, master-slave mode or business complex need to connect different sub-Libraries to support the business. Our project is the latter model, the Internet to find a lot, mostly based on JPA to do a long data source solution, or is the old spring Multi-data
