springboot+mybatis-plus的logback+Slf4j日志配置及sql打印

第一步加入如下log包

// https://mvnrepository.com/artifact/org.projectlombok/lombok
compileOnly 'org.projectlombok:lombok:1.18.6'
annotationProcessor 'org.projectlombok:lombok:1.18.6'
// https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-logging
compile group: 'org.springframework.boot', name: 'spring-boot-starter-logging', version: '2.3.1.RELEASE'

　在resources下新建logback-spring.xml放在resources下springboot可自动装配。

如果想自定义可在mybatisplus配置中设置如下

# 加载全局的配置文件
configLocation: classpath:mybatis/mybatis-config.xml

logback-spring.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<configuration scan="true" scanPeriod="60 seconds" debug="false">
    <contextName>logback</contextName>
    <!--定义日志文件的存储地址 勿在 LogBack 的配置中使用相对路径-->

    <!-- 彩色日志格式 -->
    <property name="CONSOLE_LOG_PATTERN" value="${CONSOLE_LOG_PATTERN:-%clr(%d{yyyy-MM-dd HH:mm:ss.SSS}){faint} %clr(${LOG_LEVEL_PATTERN:-%5p}) %clr(${PID:- }){magenta} %clr(---){faint} %clr([%15.15t]){faint} %clr(%-40.40logger{39}){cyan} %clr(:){faint} %m%n${LOG_EXCEPTION_CONVERSION_WORD:-%wEx}}"/>
    <!-- 控制台输出 -->

        <!--日志级别过滤INFO以下-->
        <filter class="ch.qos.logback.classic.filter.ThresholdFilter">

        <appender-ref ref="STDOUT" />
        <appender-ref ref="FILE" />
    </root>
<!--    mapper（sql）日志级别，放在yml控制-->
<!--    <logger name="com.example.gradle.mapper" level="debug" />-->


</configuration>

　　

 mapper（sql）日志级别

logging:
  level:
    com.example.gradle.mapper: debug

　使用例子

@RestController
@RequestMapping("/pay-record")
@Slf4j
public class PayRecordController {

    @Autowired
    private IPayRecordService service;

    /**
     *  查询列表
     * @return
     */
    @GetMapping("/list")
    public AjaxResult list(PayRecord payRecord) {
        log.info("日志测试");
        LambdaQueryWrapper<PayRecord> wrapper = new QueryWrapper<PayRecord>().lambda();
        if(null != payRecord.getPayId()){
            wrapper.eq(PayRecord::getPayId,payRecord.getPayId());
        }

        return AjaxResult.success(service.list(wrapper));
    }

}

　　打印出的log

　　完美解决sql的打印

生产环境只需吧mapper日志级别改为info即可。
