java - slf4j+logback无法输出日志？

Question

pom.xml中已经引入依赖

      <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-api</artifactId>
            <version>1.7.21</version>
        </dependency>
  
        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-nop</artifactId>
            <version>1.7.12</version>
        </dependency>

        <dependency>
            <groupId>ch.qos.logback</groupId>
            <artifactId>logback-core</artifactId>
            <version>1.1.7</version>
        </dependency>

在resources目录下已经创建了logback.xml

<?xml version="1.0" encoding="UTF-8"?>

<configuration debug="true">

<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
    <!-- encoders are assigned the type
         ch.qos.logback.classic.encoder.PatternLayoutEncoder by default -->
    <encoder>
        <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
    </encoder>
</appender>

<root level="debug">
    <appender-ref ref="STDOUT"/>
</root>
</configuration>

测试类中已经引入了logger

  private  Logger logger = LoggerFactory.getLogger(this.getClass());

 @Test
    public void getById() throws Exception {
        Seckill seckill = seckillService.getById(1000L);
        logger.error("seckill={}",seckill);
    }

测试通过但是控制台不打印日志

请问如何解决？

Answer 1

logback.xml is placed in the root path of the class directory. If it is in maven, put it in testresources
