springboot JPA日志打印-Toy模板网

这篇具有很好参考价值的文章主要介绍了springboot JPA日志打印。希望对大家有所帮助。如果存在错误或未考虑完全的地方，请大家不吝赐教，您也可以点击"举报违法"按钮提交疑问。

1、在springboot整合jpa后再配置文件applcation.yml的时候show-sql要设置为true

spring:
  profiles:
    active: dev
    #JPA(java持久层API)配置
  jpa:
    #指定数据库管理系统
    database: MYSQL
    #显示或者不记录每个sql查询
    show-sql: true
    hibernate:
      ddl-auto: update
      #命名策略
      naming:
        strategy: org.hibernate.cfg.ImprovedNamingStrategy
      database-platform: org.hibernate.dialect.MySQL5InnoDBDialect

这时去执行请求，后台就会打印sql，但是不会现实参数，如果需要现在参数需要再在application.yml中添加下面的配置

logging:
  level:
    org.springframework.security:
      - debug
      - info
    org.springframework.web: error
    org.hibernate.SQL: debug
    org.hibernate.engine.QueryParameters: debug
    org.hibernate.engine.query.HQLQueryPlan: debug
    org.hibernate.type.descriptor.sql.BasicBinder: trace

这时去执行请求，后台就会将参数和sql都打印出来，但是sql和参数是分开的。
下面我们让sql和参数合并在一起打印出来
1、第一步添加依赖

        <!--监控sql日志-->
        <dependency>
            <groupId>org.bgee.log4jdbc-log4j2</groupId>
            <artifactId>log4jdbc-log4j2-jdbc4.1</artifactId>
            <version>1.16</version>
        </dependency>

2、创建log4jdbc.log4j2.properties 配置文件，并添加以下内容

# If you use SLF4J. First, you need to tell log4jdbc-log4j2 that you want to use the SLF4J logger
log4jdbc.spylogdelegator.name=net.sf.log4jdbc.log.slf4j.Slf4jSpyLogDelegator

3、修改application.yml中的mysql连接信息
jpa打印sql日志,spring boot,hibernate,log4j
4、在resources 里新建 logback.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<configuration scan="true">
    <!-- 从application.yml 中注入变量  -->
    <!-- <springProperty scope="context" name="LOG_PATH" source="log.home"/> -->

    <property name="LOG_PATH" value="./logs"/>
