在数据库操作中，异常是不可避免的：网络抖动导致连接超时、SQL 语法错误引发执行失败、业务逻辑疏漏造成主键冲突……这些问题如果处理不当，可能直接导致系统崩溃或数据错误。本文聚焦 MyBatis 框架下的异常处理，覆盖从底层 JDBC 异常（如 SQLException）到 MyBatis 封装异常（如 PersistenceException），再到业务层自定义异常的全链路处理方法，帮助开发者构建「可感知、可定位、可恢复」的异常处理体系。

mybatis 超时异常怎么捕获
最新发布
10-12
在MyBatis中，当执行SQL语句的时间超过所设置的超时时，会抛出`org.apache.ibatis.exceptions.PersistenceException`或其子类，其中常见的超时异常可能是`SqlTimeoutException`或`TimeoutException`。你可以通过以下几种方式捕获并处理这类异常： 1. **全局异常处理**： 在MyBatis的全局`mybatis-config.xml`文件中，可以在`<configuration>`标签下添加一个`<exception-handler>`元素，自定义异常处理器来捕获超时异常。 ```xml <global-config> <exception-handler type="com.example.MyExceptionHandler"/> </global-config> ``` 然后在`MyExceptionHandler`中检查并处理异常： ```java public class MyExceptionHandler implements ExceptionHandler { @Override public void handleException(throwable t) { if (t instanceof SqlTimeoutException || t instanceof TimeoutException) { // 捕获到超时异常，记录日志或抛出自定义异常 } } } ``` 2. **Mapper接口方法上**： 你也可以在每个可能抛出超时异常的Mapper接口方法上使用`@GlobalThreshold`注解来指定超时时间，并在`catch`块里处理异常。 ```java @GlobalThreshold(value = "60000", unit = TimeUnit.MILLISECONDS) List<User> getUsers(); ``` 3. **事务管理**： 如果是在事务上下文中，可以使用`try-with-resources`语句或手动关闭连接时检查`SQLException`以捕获超时异常。 ```java try (Connection conn = dataSource.getConnection()) { Executor executor = sqlSession.getExecutor(connection); List<User> users = executor.selectList("getUsers"); } catch (SqlTimeoutException e) { // 处理超时异常 } ```
