Mybatis 如何开启控制台打印sql语句
作者:@解忧杂货铺 时间:2023-08-02 02:01:53
springboot+mybatis整合过程中,开启控制台sql语句打印的多种方式:
方法一
1>(spring+mybatis)在mybatis的配置文件中添加
<settings>
<!-- 打印sql日志 -->
<setting name="logImpl" value="STDOUT_LOGGING" />
</settings>
mybatis的配置文件----mybatis-config.xml如下:
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
<settings>
<!-- 打印sql日志 -->
<setting name="logImpl" value="STDOUT_LOGGING" />
</settings>
</configuration>
2> (springboot+mybatis)在springboot的配置文件----appcation.yml中添加
mybatis:
configuration:
log-impl: org.apache.ibatis.logging.stdout.StdOutImpl
ps:
IDEA中,springboot默认配置文件是application.properties文件,但是yml文件在语法上更加简洁,更有层次感,所以此处是用yml语法,properties中好像是这么写的:
mybatis.configuration.log-impl= org.apache.ibatis.logging.stdout.StdOutImpl
控制台可以打印了。。。。。
方法二
在springboot+mybatis整合中,可以将springboot的配置文件添加如下一段也可:
logging:
level:
com.lucifer.springboot.cache.mapper: debug
ps: com.lucifer.springboot.cache.mapper是包名
方法三
如果你使用的是springboot+mybatis-plus的话:
<dependency>
<groupId>com.baomidou</groupId>
<artifactId>mybatis-plus-boot-starter</artifactId>
<version>3.3.1</version>
</dependency>
application.yml:
mybatis-plus:
configuration:
log-impl: org.apache.ibatis.logging.stdout.StdOutImpl
控制台打印:
JDBC Connection [HikariProxyConnection@1006460161 wrapping com.mysql.cj.jdbc.ConnectionImpl@37cccae8] will not be managed by Spring
