SpringBoot集成P6Spy實現(xiàn)SQL日志的記錄詳解

更新時間：2022年11月28日 16:43:51 作者：喜羊羊sk

P6Spy是一個框架，它可以無縫地攔截和記錄數(shù)據(jù)庫活動，而無需更改現(xiàn)有應(yīng)用程序的代碼。一般我們使用的比較多的是使用p6spy打印我們最后執(zhí)行的sql語句

P6Spy簡介

P6Spy是一個可以用來在應(yīng)用程序中攔截和修改數(shù)據(jù)操作語句的開源框架。

通過P6Spy可以對SQL語句進行攔截，相當(dāng)于一個SQL語句的記錄器，這樣我們可以用它來作相關(guān)的分析，比如性能分析。

application.yml

spring:
datasource:
driver-class-name: com.mysql.cj.jdbc.Driver
#driver-class-name: com.p6spy.engine.spy.P6SpyDriver
type: com.alibaba.druid.pool.DruidDataSource
url: jdbc:mysql://localhost:3306/course_db?serverTimezone=GMT%2B8

# 打開mybatis-plus的sql日志輸出

entity

@Data
@NoArgsConstructor
@AllArgsConstructor
@TableName("course_1")
public class Course {
    @TableField("cid")
    private Long cId;
    private String cName;
    private Integer userId;
    private String cStatus;
}

Mapper

public interface CourseMapper extends BaseMapper<Course> {
}

啟動類

@SpringBootApplication
@MapperScan(basePackages = "cn.zysheep.mapper")
public class ShardingjdbcdemoApplication {
    public static void main(String[] args) {
        SpringApplication.run(ShardingjdbcdemoApplication.class, args);
    }
}

測試類

@SpringBootTest
@Slf4j
class ShardingjdbcdemoApplicationTests {
    @Autowired
    private CourseMapper courseMapper;
    @SneakyThrows
    @Test
    void findCourse() {
        courseMapper.selectList(null).forEach(System.out::println);
    }
}

mybatis-plus也可以打印輸出的sql日志，但是不是我們想要的效果，如何來控制想要的sql日志輸出，可以使用P6Spy開源產(chǎn)品。

P6Spy入門使用

spy.properties

resources目錄添加配置文件，類似log4j.xml，記錄配置信息

module.log=com.p6spy.engine.logging.P6LogFactory,com.p6spy.engine.outage.P6OutageFactory
# sql日志打印輸出
# 1、logMessageFormat=com.p6spy.engine.spy.appender.SingleLineFormat
# 2、logMessageFormat=com.p6spy.engine.spy.appender.CustomLineFormat
# customLogMessageFormat=%(currentTime) | SQL use time: %(executionTime) ms | connect info: %(category)-%(connectionId) | execute sql: %(sql)
# 3、自定義日志打印(全限定類名)
logMessageFormat=cn.zysheep.config.P6SPYConfig
# 使用日志系統(tǒng)記錄sql
appender=com.p6spy.engine.spy.appender.Slf4JLogger
## 配置記錄Log例外
excludecategories=info,debug,result,batc,resultset
# 設(shè)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(qū)動
driverlist=com.mysql.cj.jdbc.Driver
# 是否開啟慢SQL記錄
outagedetection=true
# 慢SQL記錄標準秒
outagedetectioninterval=2

P6Spy有內(nèi)置的SQL輸出格式，如上配置文件。這里我們使用自定義SQL日志打印

P6SPYConfig

public class P6SPYConfig  implements MessageFormattingStrategy {
    @Override
    public String formatMessage(int connectionId, String now, long elapsed, String category, String prepared, String sql, String url) {
        Map<String, Object> message = new LinkedHashMap<>(8);
        String newPrepared = prepared.replace("   ", "").replace("\n", " ");
        message.put("prepared", newPrepared);
        String newSql = sql.replace("   ", "").replace("\n", " ");
        message.put("sql", newSql);
        return JSONObject.toJSONString(message, true);
    }
}
