在MyBatis中实现控制台输出SQL参数的具体方案

@Configuration
public class MyBatisPlusConfig {
    @Bean
    public MybatisPlusInterceptor mybatisPlusInterceptor() {
        MybatisPlusInterceptor interceptor = new MybatisPlusInterceptor();
        interceptor.addInnerInterceptor(new SqlLogInterceptor());
        return interceptor;
    }
}

  configuration:
    log-impl: org.apache.ibatis.logging.stdout.StdOutImpl

# 原 JDBC URL 前追加 "jdbc:log4jdbc:"

    url: jdbc:log4jdbc:mysql://localhost:3306/dbname
    driver-class-name: net.sf.log4jdbc.DriverSpy

<logger name="jdbc.sqlonly" level="DEBUG"/>  <!-- 仅输出 SQL -->
<logger name="jdbc.sqltiming" level="INFO"/> <!-- 输出 SQL 及执行时间 -->

@Intercepts({@Signature(type = Executor.class, method = "update", args = {MappedStatement.class, Object.class}),
             @Signature(type = Executor.class, method = "query", args = {MappedStatement.class, Object.class, RowBounds.class, ResultHandler.class})})
public class SqlParamInterceptor implements Interceptor {
    @Override
    public Object intercept(Invocation invocation) throws Throwable {
        Object parameter = invocation.getArgs()[1];
        // 解析参数并拼接 SQL
        System.out.println("Params: " + parameter);
        return invocation.proceed();
    }
}
