Jndi The default address for the Wildfly service Management console is Http://127.0.0.1:9990/console, and after linking because there are no users, you will be prompted to add users through Add-user.bat. Just follow the prompts to create the user and then log in to the console with the user you created. There is a problem here, when creating the data source, you need to select the JDBC driver deployed in the system, then you need to put the driver ja

The following are the steps for a specific configuration:1. First configure the Jndi data source under Tomcat. The specific storage directory Apache-tomcat-7.0.59\conf\catalina\localhostOsh.xml(2) The database driver jar is placed in the Lib directory in the Tomcat installation file.(3) Spring Applicationcontext.xml is configured in DataSource:Note that java:comp/env must be added to the Vlaue attribute, followed by the name of resource in servers(4)

In our project, we encountered the following problem: our project needs to connect multiple databases, and different customers access different databases as needed during each access. We used to configure a data source in spring and hibernate frameworks, so the datasource attribute of sessionfactory always points to this data source. And remains unchanged. All Dao accesses the database through this

The same project can sometimes involve multiple databases, or multiple data sources. Multiple data sources can be divided into two situations:1) Two or more databases are not relevant, independent of each other, in fact, this can be developed as two projects. For example, in the game development of a database is a plat

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

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.

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
