一、mybatisplus配置多数据源
spring:
# 配置多数据源信息
datasource:
# 配置数据源类型
dynamic:
# 设置默认数据源或者数据源组
primary: master
strict: false
datasource:
master:
url: jdbc:mysql://localhost:3307/mybatis_plus?characterEncoding=utf-8&SSL=false
driver-class-name: com.mysql.cj.jdbc.Driver
username: root
password: 123456
slave_1:
url: jdbc:mysql://localhost:3307/mybatis_plus_1?characterEncoding=utf-8&SSL=false
driver-class-name: com.mysql.cj.jdbc.Driver
username: root
password: 123456
mybatis-plus:
configuration:
log-impl: org.apache.ibatis.logging.stdout.StdOutImpl
# 配置统一表的前缀名
global-config:
db-config:
table-prefix: t_
# 配置全局的主键生成策略
id-type: auto
# 配置包的别名
type-aliases-package: com.cjc.mybatisplus.pojo
#配置扫描枚举包
type-enums-package: com.cjc.mybatisplus.enums
二、在service实现类上添加@DS
@Service
@DS("slave_1")
public class ProductServiceImpl extends ServiceImpl<ProductMapper,Product> implements ProductService {
}
@Service
@DS("master")
public class UserServiceImpl extends ServiceImpl<UserMapper, User> implements UserService {
}
三、在pom.xml中添加
<dependency>
<groupId>com.baomidou</groupId>
<artifactId>dynamic-datasource-spring-boot-starter</artifactId>
<version>3.5.0</version>
</dependency>
四、测试
@SpringBootTest
public class MultiSourceTest {
@Autowired
private UserService userService;
@Autowired
private ProductService productService;
@Test
public void Test01(){
User byId = userService.getById(3);
System.out.println(byId);
Product byId1 = productService.getById(1);
System.out.println(byId1);
}
}
