mybaties plus配置连接池

MyBatis Plus provides a convenient way to configure connection pools. Here is an example of how you can configure a connection pool using MyBatis Plus:

1. First, include the necessary dependencies in your project. You will need to include the MyBatis Plus dependency along with the JDBC driver for your database.

2. Next, create a configuration file for MyBatis Plus. This file typically has the name "mybatis-plus-config.xml" and is placed in the resources directory of your project.

3. In the configuration file, you can define the properties for the connection pool. Here is an example configuration for a HikariCP connection pool:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
    <settings>
        <setting name="cacheEnabled" value="true"/>
        <setting name="lazyLoadingEnabled" value="true"/>
        <setting name="aggressiveLazyLoading" value="false"/>
    </settings>
    <dataSource type="com.zaxxer.hikari.HikariDataSource">
        <property name="driverClassName" value="com.mysql.cj.jdbc.Driver"/>
        <property name="jdbcUrl" value="jdbc:mysql://localhost:3306/mydatabase?serverTimezone=UTC"/>
        <property name="username" value="root"/>
        <property name="password" value="password"/>
        <!-- Other connection pool properties -->
    </dataSource>
</configuration>

4. Finally, in your Java code, you can use the `@MapperScan` annotation to enable scanning for mapper interfaces and automatically generate their implementations. You can specify the location of the configuration file using the `@ImportResource` annotation.

@SpringBootApplication
@MapperScan("com.example.mapper")
@ImportResource("classpath:mybatis-plus-config.xml")
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

With this configuration in place, MyBatis Plus will use the specified connection pool to manage database connections. You can customize the connection pool properties according to your requirements.

I hope this helps! Let me know if you have any further questions.
