Mybatis-Plus配置多數(shù)據(jù)源

1、引入依賴

<dependency>
    <groupId>com.baomidou</groupId>
    <artifactId>dynamic-datasource-spring-boot-starter</artifactId>
    <version>3.5.0</version>
</dependency>

2、配置多數(shù)據(jù)源

spring:
    # 配置數(shù)據(jù)源信息
    datasource:
		dynamic:
			# 設(shè)置默認(rèn)的數(shù)據(jù)源或者數(shù)據(jù)源組,默認(rèn)值即為master
            primary: master
            # 嚴(yán)格匹配數(shù)據(jù)源,默認(rèn)false.true未匹配到指定數(shù)據(jù)源時(shí)拋異常,false使用默認(rèn)數(shù)據(jù)源
            strict: false
            datasource:
				master:
                    url: jdbc:mysql://localhost:3306/mybatis_plus?characterEncoding=utf8&useSSL=false
                    driver-class-name: com.mysql.cj.jdbc.Driver
                    username: root
                    password: 123456
				slave_1:
                    url: jdbc:mysql://localhost:3306/mybatis_plus_1?characterEncoding=utf8&useSSL=false
                    driver-class-name: com.mysql.cj.jdbc.Driver
                    username: root
                    password: 123456

3、創(chuàng)建用戶service

public interface UserService extends IService<User> {
}

@DS("master") //指定所操作的數(shù)據(jù)源
@Service
public class UserServiceImpl extends ServiceImpl<UserMapper, User> implements UserService {
}

5、創(chuàng)建商品service

public interface ProductService extends IService<Product> {
}

@DS("slave_1")//指定所操作的數(shù)據(jù)源
@Service
public class ProductServiceImpl extends ServiceImpl<ProductMapper, Product> implements ProductService {
}
