其中,InnerInterceptor是MyBatis-Plus中的一个内部拦截器接口,用于拦截SQL语句的执行。 InnerInterceptor接口的主要作用是: 拦截SQL语句的执行。 在执行前、执行后或执行过程中对SQL语句进行修改或增强。 当你实现InnerInterceptor接口并使用MyBatis-Plus时,你可以在方法intercept(ExecutorWrapper executor, StatementHandler ...

拦截器通过实现Mybatis提供的Interceptor拦截接口,重写了三个方法:setProperties/plugin/ intercept,三者执行顺序是setProperties—》plugin—》Interceptor。 代码语言:javascript 复制 setProperties方法:该方法通过设置属性,将核心配置文件configuration.xml文件中对拦截器的配置项下的属性获取过来,便于在拦截器中使用。
在以上代码中,我们自定义了一个SqlPrintInterceptor类,实现了MybatisPlusInterceptor接口,并重写了其中的intercept方法。在intercept方法中,我们获取到执行的sql语句,并打印输出。 使用自定义Interceptor 接下来,我们来演示如何使用自定义的Interceptor来打印SQL语句: ...
