spring-boot配置打印sql

开发阶段需要打印sql，方便排查问题

有2种方法

1. spring-boot jpa配置

# application-dev.properties
spring.jpa.show-sql=true

2. logback配置
修改hibernate mybatis相关包的日志级别即可

    <!-- show parameters for hibernate sql 专为 Hibernate 定制 -->
    <!--<logger name="org.hibernate.type.descriptor.sql.BasicBinder" level="TRACE"/>-->
    <logger name="org.hibernate.type.descriptor.sql.BasicExtractor" level="DEBUG"/>
    <logger name="org.hibernate.SQL" level="DEBUG"/>
    <logger name="org.hibernate.engine.QueryParameters" level="DEBUG"/>
    <logger name="org.hibernate.engine.query.HQLQueryPlan" level="DEBUG"/>

    <!--myibatis log configure-->
    <logger name="com.apache.ibatis" level="TRACE"/>
    <logger name="java.sql.Connection" level="DEBUG"/>
    <logger name="java.sql.Statement" level="DEBUG"/>
    <logger name="java.sql.PreparedStatement" level="DEBUG"/>
