MyBatis Interceptors: Implementation Guide

To use interceptors in MyBatis, you need to follow these steps:

1. Capture aircraft or vessel
2. catch before arrival
3. extension

public class MyInterceptor implements Interceptor {
    
    @Override
    public Object intercept(Invocation invocation) throws Throwable {
        // 在这里编写拦截器的逻辑
        return invocation.proceed();
    }

    @Override
    public Object plugin(Object target) {
        return Plugin.wrap(target, this);
    }

    @Override
    public void setProperties(Properties properties) {
        // 可以设置一些拦截器的属性
    }
}

1. Configure interceptors in the MyBatis configuration file.

<plugins>
    <plugin interceptor="com.example.MyInterceptor">
        <property name="property1" value="value1"/>
        <property name="property2" value="value2"/>
    </plugin>
</plugins>

1. Factory for creating SQL sessions.

Interceptor myInterceptor = new MyInterceptor();
Configuration configuration = sqlSessionFactory.getConfiguration();
configuration.addInterceptor(myInterceptor);

This way allows you to use custom interceptors in MyBatis. You can write your own interception logic in the intercept method, such as modifying SQL, adding logs, etc.
