直接在application.yml/properties文件中进行配置

引入依赖：

	<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <!-- boot父依赖  可以指定版本号（指定后boot其他依赖不加版本号不报错 否则报错） -->
        <version>2.3.6.RELEASE</version>
        <relativePath/>
    </parent>
    <dependencies>
		<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
            <!-- 提供Web开发场景所需的底层所有依赖，springboot默认集成了tomcat服务器 -->
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-logging</artifactId>
            <!-- 点进去里面有logback、log4j和slf4j -->
            <!--  如果添加了这个依赖，SpringBoot 应用将自动使用 logback 作为应用日志框架 -->
        </dependency>
    </dependencies>

1、Mybatis内置的日志工厂

Mybatis内置的日志工厂提供日志功能，具体的日志实现有以下几种工具：

slf4j

ApacheEnguSg Commons Logging

Log4j 2

Log4j

JDK logging

具体选择哪个日志实现工具由MyBatis的内置日志工厂确定。它会使用最先找到的（按上文列举的顺序查找）。如果一个都未找到，日志功能就会被禁用。

配置log-impl：可供选择的有以下几种

SpringBoot打印系统执行的sql语句及日志配置指南

yml中：

mybatis-plus:
  configuration:
    log-impl: org.apache.ibatis.logging.stdout.StdOutImpl #这个是可以打印sql、参数、查询结果的,只会打印到控制台不会输出到日志文件中
			 #org.apache.ibatis.logging.log4j.Log4jImpl:这个不打印查询结果
  mapper-locations: classpath:mapper/*.XML
  type-aliases-package: com.example.plan.entity # 指定的包名

或properties中：

# mybatis plus
mybatis-plus.mapper-locations=classpath:mapper/*Mapper.xml
mybatis-plus.type-aliases-package=com.example.plan
mybatis-plus.configuration.map-underscore-to-camel-case=true
mybatis-plus.configuration.log-impl=org.apache.ibatis.logging.stdout.StdOutImpl # 重点

StdOutImpl控制台输出结果：

==>  Preparing: select id, name, sex from t_user where sex = ?
==> Parameters: 0(Integer)
<==      Total: 8

/**
 *第一行是执行的sql语句
 *第二行是传入的参数
 *第三行是返回结果的行数
 */

补充：

log-impl用于设置打印sql的日志实现，指定的值为org.apache.ibatis.logging.Log接口的其中的一个实现类

在这里以StdOutImpl为例

public class StdOutImpl implements Log {

  public StdOutImpl(String clazz) {
    // Do Nothing
  }

  @Override
  public boolean isDebugEnabled() {
    return true;
  }

  @Override
  public boolean isTraceEnabled() {
    return true;
  }

  @Override
  public void error(String s) {
    System.err.println(s);
  }

  @Override
  public void debug(String s) {
    System.out.println(s);
  }

  @Override
  public void trace(String s) {
    System.out.println(s);
  }

  @Override
  public void warn(String s) {
    System.out.println(s);
  }
}

方法里面的输出，是用的System.out/error.println方法，所以如果配置为org.apache.ibatis.logging.stdout.StdOutImpl就只会在控制台窗口打印，不会记录到日志文件。

如果需要保存打印SQL到文件就不能设置为StdOutImpl，可以设置为Slf4jImpl。部分代码如下，使用的是Log的方法，保存到文件中。

  @Override
  public void error(String s) {
    log.error(s);
  }

  @Override
  public void debug(String s) {
    log.debug(s);
  }

  @Override
  public void trace(String s) {
    log.trace(s);
  }

  @Override
  public void warn(String s) {
    log.warn(s);
  }

也可以不设置。然后对应接口所在包设置logback对应包的日志等级[debug\info\error\warn等]，即下面所提到的第二种方式。

级别从高到低：OFF 、 FATAL 、 ERROR 、 WARN 、 INFO 、 DEBUG 、 TRACE 、 ALL

2、Spring Boot集成Mybatis

SpringBoot打印系统执行的sql语句及日志配置指南

logging.file.name设置日志文件：支持绝对路径、相对路径，相对路径的话是相对应用的根目录，比如logging.file.name=logs/demo.log;

默认：spring.log

logging.file.path设置日志路径：支持绝对路径、相对路径，比如 logging.file.path=logs，日志文件默认会存为 spring.log；

默认：根路径/LOG_PATH_IS_UNDEFINED/

yml中：

#spring boot集成mybatis的方式打印sql
logging:
    level:
      com.xxx.mapper: debug # 包路径为mapper文件包路径
      org.springframework: warn
      org.apache.ibatis.logging: debug
    file:
      path/name: #加不加这个配置就看你的resources目录下是否有logbackxxxx之类的xml文件，有的话会自动加载这个，识别里面的logpath。如果外部的这个日志配置和xml文件中具有相同的配置的话，哪个优先级更高一点？

此时，如果有相应的log配置文件，比如叫logback-spring.xml。

配置文件中部分内容如下：

	<!--开发环境:打印控制台-->
    <springProfile name="dev,prod,test">
        <logger name="com.example.plan" level="info"/>
    </springProfile>

    <root level="info">
 js       <appender-ref ref="CONSOLE"/>
        <appender-ref ref="INFO_FILE"/>
        <appender-ref ref="WARNING_FILE"/>
        <appender-ref ref="ERROR_FILE"/>
    </root>
    <!-- 其中的springProfile标签指定了name，那么在application.yml文件中要启用dev,prod,test中的一个，不然输出的内容为空。logger标签中的name限定了范围。 -->

相应的yml中的logging配置：

logging:
  config: ${spring.config.location}logback-spring.xml # 不加也行，Springboot默认的日志配置文件名称为logback.xml和logback-spring.xml、logbackxxxx.xml
spring:
  profiles:
    active: dev

3、总结

sql其它日志信息简述配置
只打印到控制台不输出只打印sql到控制台仅需log-impl配置为StdOutImpl
只打印到控制台输出其它日志信息保存到文件，sql只打印到控制台，不保存到文件中log-impl配置为StdOutImpl，再加上logging的配置（logging.config指定配置文件/ resources目录下有符合spring boot自动化配置文件名的logbackxxx.xml/ yml中logging.level/file配置完整一些）
打印到控制台且输出到日志文件中输出sql和其它日志信息保存到文件中，sql也打印到控制台log-impl为Slf4jImpl/或者不设置，总之不能设置为StdOutImpl，再加上logging的配置即可

配置为logback-test.xml后，控制台的输出：

15:50:13,315 |-INFO in ch.qos.logback.classic.LoggerContext[logback] - Found resource [logback-test.xml] at [file:/Users/congee/Desktop/code/GService/service/target/classes/logback-test.xml]

配置完号后的紧接着的日志输出：

可以直观的感受到前面日志的时间格式的变化。
