## 数据源缺失处理器
|
||||
|
||||
当无法根据 `dataSourceKey` 找到数据源时，默认情况下会抛出 `IllegalStateException` 异常。
|
||||
数据源缺失处理器（`DataSourceMissingHandler`）提供了更加灵活的处理方式，你可以通过它自定义处理逻辑（如：记录日志、抛出异常或主动初始化新的数据源）。
|
||||
|
||||
### 使用示例
|
||||
|
||||
我们推荐使用 `MyBatisFlexCustomizer` 来配置数据源缺失处理器，如下所示：
|
||||
|
||||
```java
|
||||
@Configuration
|
||||
public class MyBatisFlexConfiguration implements MyBatisFlexCustomizer {
|
||||
|
||||
@Override
|
||||
public void customize(FlexGlobalConfig globalConfig) {
|
||||
// ...
|
||||
|
||||
// 配置数据源缺失处理器：此处演示的是以后备逻辑主动初始化数据源
|
||||
globalConfig.setDataSourceMissingHandler((dataSourceKey, dataSourceMap) -> {
|
||||
// 根据 key 获取数据源
|
||||
DataSource ds = customCreateDataSource(dataSourceKey);
|
||||
|
||||
// 取不到的时候返回 null，后续代码逻辑仍然由 FlexDataSource 处理（即抛出异常）
|
||||
if (ds == null) return null;
|
||||
|
||||
// 添加新的数据源，避免下次再次触发和创建
|
||||
dataSourceMap.put(dataSourceKey, ds);
|
||||
|
||||
return dataSourceMap;
|
||||
});
|
||||
|
||||
// ...
|
||||
}
|
||||
|
||||
}
|
||||
```
|
||||
|
||||
## 更多的 Spring 或 Solon Yaml 配置支持
