Tips:
springboot版本：2.0.8.RELEASE
jdk：1.8
在使用JPA的時(shí)候借尿，show-sql顯示不是那么友好刨晴，為了得到可執(zhí)行的SQL語句，找到了p6spy這個(gè)工具路翻。網(wǎng)上很多版本老舊狈癞，在新版中會(huì)出現(xiàn)各種報(bào)錯(cuò)，所以整理了個(gè)工具帚桩，希望能快速幫到大家亿驾，避免走彎路。 至于為什么有這個(gè)需求账嚎，一個(gè)是因?yàn)镴PA打印出來很多莫瞬？號(hào)，不能進(jìn)行參數(shù)替換郭蕉，還有就是因?yàn)閼刑垩迲小?/p>
- 導(dǎo)入maven依賴
<dependency>
<groupId>p6spy</groupId>
<artifactId>p6spy</artifactId>
<version>3.8.6</version>
</dependency>
- 修改數(shù)據(jù)源配置，只需更改
driver-class-name和url,以pg,mysql為例
pg
spring:
datasource:
# driver-class-name: org.postgresql.Driver
driver-class-name: com.p6spy.engine.spy.P6SpyDriver
# url: jdbc:postgresql://localhost:5432/postgres
url: jdbc:p6spy:postgresql://localhost:5432/postgres
username: postgres
password: 123456
mysql
spring:
datasource:
url: jdbc:p6spy:mysql://localhost:3306/xxx?useUnicode=true&useSSL=false&serverTimezone=UTC
username: root
password: 123456
driver-class-name: com.p6spy.engine.spy.P6SpyDriver
3.新增配置 spy.properties 到resources下
logMessageFormat=com.p6spy.engine.spy.appender.CustomLineFormat
customLogMessageFormat=sql -> %(sqlSingleLine)
appender=com.p6spy.engine.spy.appender.StdoutLogger
#appender=com.p6spy.engine.spy.appender.FileLogger
#appender=com.p6spy.engine.spy.appender.Slf4JLogger
#customLogMessageFormat=%(sqlSingleLine)
#customLogMessageFormat=%(currentTime)|%(executionTime)|%(category)|connection%(connectionId)|%(sqlSingleLine)
這里只是為了快速得到一個(gè)可執(zhí)行的SQL召锈，更高級(jí)的用法還請(qǐng)自行研究旁振，哈哈。
給出一個(gè)JPA結(jié)合p6spy打印SQL的例子。感覺不錯(cuò)點(diǎn)個(gè)贊吧拐袜。
sql -> drop table if exists book cascade
sql -> create table book (id serial not null, author varchar(255), name varchar(255), time time, primary key (id))
sql -> insert into book (author, name, time) values ('1', '1', '2019-12-02T10:53:23.941+0800')
sql -> select currval('book_id_seq')
sql -> insert into book (author, name, time) values ('2', '2', '2019-12-02T10:53:23.941+0800')
sql -> select currval('book_id_seq')
sql -> insert into book (author, name, time) values ('3', '3', '2019-12-02T10:53:23.941+0800')
sql -> select currval('book_id_seq')
sql -> insert into book (author, name, time) values ('4', '4', '2019-12-02T10:53:23.941+0800')
sql -> select currval('book_id_seq')
sql -> select book0_.id as id1_0_, book0_.author as author2_0_, book0_.name as name3_0_, book0_.time as time4_0_ from book book0_ where book0_.author='1' and book0_.name='1'
