Mybatis 开启控制台打印sql语句
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.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.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==> Preparing: SELECT id,user_name,age FROM user WHERE (user_name = ?) ==> Parameters: 张三(String)<== Columns: id, user_name, age<== Row: 1, 张三, 18<== Total: 1
