推荐答案

您必须在类路径的根目录(通常在src/main/resources中)定义一个logback.xml文件.

You have to define a logback.xml file at the root of the classpath (typically in src/main/resources).

示例:

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <include resource="org/springframework/boot/logging/logback/base.xml" />

    <appender name="FILE" class="ch.qos.logback.core.FileAppender">
        <file>logs.log</file>
        <append>true</append>
        <encoder>
            <pattern>%-4relative [%thread] %-5level %logger{35} - %msg%n
            </pattern>
        </encoder>
    </appender>


    <logger name="org.springframework.web" level="DEBUG" />
    <logger name="your.custom.package" level="TRACE" />

    <root level="INFO">
        <appender-ref ref="FILE" />
    </root>
</configuration>

此配置将创建一个logs.log文件(在您的Maven项目的根目录中).

This configuration creates a logs.log file (at the root of your Maven project).
