mybatis plus time

根据提供的引用内容，没有直接提到Mybatis Plus Time这个概念。但是可以根据引用中提到的ORM框架Mybatis和引用中提到的新增和修改时间，推测Mybatis Plus Time可能是指Mybatis Plus框架中用于处理时间的相关功能。

Mybatis Plus是Mybatis的增强版，提供了更多的功能和便利的操作。其中包括了对时间的处理，例如自动填充创建时间和修改时间等。在使用Mybatis Plus时，可以通过配置实现自动填充时间字段，避免手动设置时间的繁琐操作。

mybatis plus log

MyBatis Plus provides a logging feature that allows you to track and analyze the SQL statements executed by your application. To enable logging in MyBatis Plus, you can configure a logging implementation of your choice, such as Log4j or SLF4J.

Here is an example of configuring logging using Log4j:

1. Add the Log4j dependency to your project's build file (e.g., Maven or Gradle).

2. Create a Log4j configuration file (e.g., log4j.properties) and specify the desired logging settings. For example:

# Set root logger level to INFO and appender to console
log4j.rootLogger=INFO, console

# Define the console appender
log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.layout=org.apache.log4j.PatternLayout
log4j.appender.console.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n

3. In your MyBatis Plus configuration file (e.g., mybatis-config.xml), enable logging by adding the following lines:

<configuration>
    <!-- ... your other configuration settings ... -->
    
    <!-- Enable logging -->
    <settings>
        <setting name="logImpl" value="LOG4J"/>
    </settings>
</configuration>

Make sure to adjust the `value` attribute to match the logging implementation you are using (e.g., `LOG4J2` for Log4j 2.x).

With the above configuration, MyBatis Plus will use Log4j for logging. You can then customize the logging settings in your Log4j configuration file as needed. The logged statements will include information such as the executed SQL, parameters, and execution time.

Remember to properly configure your logging implementation according to its documentation and your project's needs.

mybatis plus 小于

Mybatis-plus中小于的写法为lt，具体使用方法如下：

queryWrapper.lt("create_time", localDateTime);

其中，queryWrapper是查询条件构造器，create_time是表中的字段名，localDateTime是要比较的时间。这条语句的意思是查询create_time小于localDateTime的记录。
