springboot 打印sql執行信息日志

一、mybatis方式

在你的application.yml文件下面加入下面這段代碼

mybatis
  configuration:
    log-impl: org.apache.ibatis.logging.stdout.StdOutImpl 

項目啟動在你的控制台看到上面這種就說明配置成了：

打印出來的形式如下

Creating a new SqlSession
Registering transaction synchronization for SqlSession [org.apache.ibatis.session.defaults.DefaultSqlSession@2e943ddb]
JDBC Connection [HikariProxyConnection@898692052 wrapping com.mysql.jdbc.JDBC4Connection@6a0c5a04] will be managed by Spring
==>  Preparing: DELETE FROM user_info WHERE uid in ( ? , ? , ? )
==> Parameters: 44(Long), 45(Long), 46(Long)
<==    Updates: 0
Releasing transactional SqlSession [org.apache.ibatis.session.defaults.DefaultSqlSession@2e943ddb]
Transaction synchronization committing SqlSession [org.apache.ibatis.session.defaults.DefaultSqlSession@2e943ddb]
Transaction synchronization deregistering SqlSession [org.apache.ibatis.session.defaults.DefaultSqlSession@2e943ddb]
Transaction synchronization closing SqlSession [org.apache.ibatis.session.defaults.DefaultSqlSession@2e943ddb]

二、日志方式

在你的application.yml文件下面加入下面這段代碼

logging:
  level:
    com.seamax.bdsearch.dao: DEBUG

注意：com.seamax.bdsearch.dao = 你的mapper包。

打印出來的形式如下：

2019-01-24 08:02:14.245 [http-nio-8060-exec-2] DEBUG c.s.a.m.m.U.getUsernameExistSet 159 - ==>  Preparing: SELECT username FROM user_info WHERE username in ( ? , ? , ? ) 
2019-01-24 08:02:14.245 [http-nio-8060-exec-2] DEBUG c.s.a.m.m.U.getUsernameExistSet 159 - ==> Parameters: nike16(String), nike14(String), nike15(String)
2019-01-24 08:02:14.307 [http-nio-8060-exec-2] DEBUG c.s.a.m.m.U.getUsernameExistSet 159 - <==      Total: 0
2019-01-24 08:02:14.323 [http-nio-8060-exec-2] DEBUG c.s.a.m.mapper.UserMapper.saveBatch 159 - ==>  Preparing: INSERT INTO user_info ( username, password, email, telphone, birthday, createTime, updateTime ) values ( ?, ?, ?, ?, ?, ?, ? ) , ( ?, ?, ?, ?, ?, ?, ? ) , ( ?, ?, ?, ?, ?, ?, ? ) 
2019-01-24 08:02:14.323 [http-nio-8060-exec-2] DEBUG c.s.a.m.mapper.UserMapper.saveBatch 159 - ==> Parameters: nike14(String), 4f757a334d69b32b586f3694fbaaa9a9869aee184f98e009b6e02b170f92eb9f(String), [e-mail](String), null, 2018-03-02 02:01:02.0(Timestamp), 2019-01-24 08:02:14.307(Timestamp), 2019-01-24 08:02:14.307(Timestamp), nike15(String), 18a1c9f3e7a69e3f72ab5d80caea96e5c90f5fada8f9a7e92238dc4242ba03f8(String), [e-mail](String), null, 2018-03-02 02:01:02.0(Timestamp), 2019-01-24 08:02:14.307(Timestamp), 2019-01-24 08:02:14.307(Timestamp), nike16(String), 5912bd4ff3ae134b15347610b64d9f352dd3c89dd2fb5c495cf4699683b33271(String), [e-mail](String), null, 2018-03-02 02:01:02.0(Timestamp), 2019-01-24 08:02:14.307(Timestamp), 2019-01-24 08:02:14.307(Timestamp)
2019-01-24 08:02:14.338 [http-nio-8060-exec-2] DEBUG c.s.a.m.mapper.UserMapper.saveBatch 159 - <==    Updates: 3

 三、log4jdbc-log4j2使用

有時候我們程序的接口比較耗時，需要優化，這時我們可能需要了解該接口執行了哪些sql語句以及耗時

1.引入jar包

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

2.引入配置文件 log4jdbc.log4j2.properties

內容為：

log4jdbc.spylogdelegator.name=net.sf.log4jdbc.log.slf4j.Slf4jSpyLogDelegator

3.logback-spring.xml 里加入如下內容

    <logger name="jdbc.connection" level="OFF"/>
    <logger name="jdbc.resultset" level="OFF"/>
    <logger name="jdbc.resultsettable" level="OFF"/>
    <logger name="jdbc.audit" level="OFF"/>
    <!--ps：sqltiming和sqlonly差別是多打印了sql語句的耗時，如果不想要這個時間可以修改篩選里面的項。-->
    <logger name="jdbc.sqltiming" level="INFO"/>
    <logger name="jdbc.sqlonly" level="OFF"/>

4.配置文件中修改部分屬性值

如圖：

即：

  driver-class-name 修改為：net.sf.log4jdbc.sql.jdbcapi.DriverSpy

  url 修改為：jdbc:log4jdbc:mysql:// （在原來的jdbc后面加了：log4jdbc：）

---------------------------------------------------------------------------    

以上完成任務，下面看下效果

---------------------------------------------------------------------------

注意：除了打印sql執行時間外，打印的sql語句是包含sql所帶的參數的，select語句的話where后面帶參數值，insert語句的話插入對象的值都有

 

 四、p6spy使用

1.導入依賴

<dependency>
    <groupId>p6spy</groupId>
    <artifactId>p6spy</artifactId>
    <version>3.8.6</version>
</dependency>

2.修改application.properties中的數據庫驅動和url

#spring.datasource.driver-class-name=com.mysql.jdbc.Driver
#spring.datasource.url=jdbc:mysql://localhost:3306/db?serverTimezone=CTT&useUnicode=true&characterEncoding=utf-8&allowMultiQueries=true&useSSL=true
#更換為com.p6spy.engine.spy.P6SpyDriver
spring.datasource.driver-class-name=com.p6spy.engine.spy.P6SpyDriver
spring.datasource.url=jdbc:p6spy:mysql://localhost:3306/data?serverTimezone=CTT&useUnicode=true&characterEncoding=utf-8&allowMultiQueries=true&useSSL=true
spring.datasource.username=root
spring.datasource.password=123456

3.在application.properties同級目錄下創建spy.properties配置文件

module.log=com.p6spy.engine.logging.P6LogFactory,com.p6spy.engine.outage.P6OutageFactory
# 自定義日志打印
logMessageFormat=com.fkzd.framework.config.P6spySqlFormatConfig //自定義P6SpyLogger類的地址
# 使用日志系統記錄sql
appender=com.p6spy.engine.spy.appender.StdoutLogger
## 配置記錄Log例外
excludecategories=info,debug,result,batc,resultset
# 設置使用p6spy driver來做代理
deregisterdrivers=true
# 日期格式
dateformat=yyyy-MM-dd HH:mm:ss
# 實際驅動
driverlist=com.mysql.cj.jdbc.Driver
# 是否開啟慢SQL記錄
outagedetection=true
# 慢SQL記錄標准 秒
outagedetectioninterval=2

4.自定義sql輸出

import com.p6spy.engine.spy.appender.MessageFormattingStrategy;
import com.fkzd.common.utils.DateUtils;
import org.apache.commons.lang3.StringUtils;

import java.util.Date;

/**
 * 自定義 p6spy sql輸出格式
 *
 */
public class P6spySqlFormatConfig implements MessageFormattingStrategy {

    /**
     * 過濾掉定時任務的 SQL
     */
    @Override
    public String formatMessage(int connectionId, String now, long elapsed, String category, String prepared, String sql, String url) {
        return StringUtils.isNotBlank(sql) ? DateUtils.parseDateToStr("yyyy-MM-dd HH:mm:ss", new Date())
                + " | 耗時 " + elapsed + " ms | SQL 語句：" + StringUtils.LF + sql.replaceAll("[\\s]+", StringUtils.SPACE) + ";" : "";
    }
}

執行效果
