+## 多数据源配置指南
+1. 在你需要用到多数据源的项目/模块中引入多数据源jar包的maven依赖
+```xml
+<dependency>
+    <groupId>com.cnbm</groupId>
+    <artifactId>ym-dynamic-datasource</artifactId>
+    <version>1.0-SNAPSHOT</version>
+</dependency>
+```
+
+2. 配置文件中，配置多数据源，注意必须以`dynamic.datasource`作为前缀，如下（slave1,slave2可以自己随意命名，数据源不限于2个）：
+```yml
+dynamic:
+  datasource:
+    slave1:
+      driver-class-name: com.mysql.cj.jdbc.Driver
+      url: jdbc:mysql://localhost:3306/mysql?useUnicode=true&characterEncoding=UTF-8&serverTimezone=Asia/Shanghai&nullCatalogMeansCurrent=true
+      username: xxx
+      password: xxx
+    slave2:
+      driver-class-name: com.mysql.cj.jdbc.Driver
+      url: jdbc:mysql://localhost:3306/myysql?useUnicode=true&characterEncoding=UTF-8&serverTimezone=Asia/Shanghai&nullCatalogMeansCurrent=true
+      username: xxx
+      password: xxx
+```
+
+3. 在service实现中，需要指定数据源的方法上面添加注解，比如，在login这个方法调用时，指定用`slave1`这个数据源
+```java
+@DataSource("slave1")
+public Result login(HttpServletRequest request, LoginParam loginParam) {
+        ......
+}
+```
+
+4. 验证
+可以在日志中看到类似输出：`set datasource is slave1`
