Look at the Springboot official website example, there is only a simple example of hello, there is no integration mybaits related. Then found on the internet a lot of looking for an integrated demo program, are too redundant, not suitable for learning. Do not say nonsense, the following is a self-organizing demo program 1. Build a MAVEN Project 2. Import related dependencies. 3. Create a table in the database to test 4. Add a application.properties configuration file, configure the associated

Components in RibbonClientConfiguration and any components in FooConfiguration (the latter usually overwrites the former ). WARNINGThe FooConfiguration has to be @ Configuration but take care that it is not in a @ ComponentScan for the main application context, otherwise it will be shared by all the @ RibbonClients. if you use @ ComponentScan (or @ SpringBootApplication) you need to take steps to avoid it being stored ded (for instance put it in a se

); }} ※ @SpringBootApplication annotations provide automatic configuration for the project based on the content in Classpath. In this application, it is equivalent to: @Configuration,@EnableAutoConfiguration, @ComponentScan the union of the three. 3.2 Create the form file Fuck.java under the Com.example package as follows: PackageCom.example;/** * @ClassName: Fuck * @Description: TODO (here is a word describing the role of this class)

Spring Boot + Mybatis multi-data source and dynamic data source configuration method, mybatis Dynamic Data The articles on the Internet basically only have multiple data sources or only dynamic data sources. The latest projects need to use two methods at the same time. Record the configuration methods for your reference. Application scenarios The project needs to connect two different databases A and B at the same time, and they are both master-slave architecture, one write database and multiple

when you use @componentscan annotations, when you do not declare any parameters, the default is to scan the same package, and the class under the sub-package, so that you can scan to classes such as Controller,service.It is important to note that @Import can import additional configuration classes, @ImportResource can import other profiles. But you can search for other beans, including configuration classes, through @componentscan.1.4 Disabling a specific automatic configurationYou can do this
