spring - 如何仅将一些信息保存到 .log 文件

问题描述

我正在尝试设置日志记录。我有一个类 LoginAttemptService，我希望只有此类的日志才会存储在日志中。

@Service
public class LoginAttemptService {

    private final int MAX_ATTEMPT = 5;

    private LoadingCache<String, Integer> attemptsCache;
    private Logger logger = LoggerFactory.getLogger(LoginAttemptService.class);

 public void loginSucceeded(String username, String key) {
        attemptsCache.invalidate(key);
        logger.info("Successful login:  " + username + " ip address:" + key);
    }

应用属性：

logging.file = logfile.log

现在的问题是，所有内容都保存到该文件中......不仅登录尝试

编辑：我使用以下配置在我的类路径中创建了 logback.xml 文件：

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <include resource="org/springframework/boot/logging/logback/defaults.xml" />
    <property name="LOG_FILE" value="${LOG_FILE:-${LOG_PATH:-${LOG_TEMP:-${java.io.tmpdir:-/tmp}}/}spring.log}"/>

    <include resource="org/springframework/boot/logging/logback/file-appender.xml" />
    <include resource="org/springframework/boot/logging/logback/console-appender.xml" />

    <appender name="login" class="ch.qos.logback.core.FileAppender">
        <file>log1.log</file>
        <append>true</append>
        <encoder>
            <pattern>%-4relative [%thread] %-5level %logger{35} - %msg%n</pattern>
        </encoder>
    </appender>


    <logger name="com.patrikmaryska.bc_prace.bc_prace.service.LoginAttemptService" level="info" additivity="false">
        <appender-ref ref="login"/>
    </logger>

</configuration>

但它现在仍然保存到该文件中......

解决方案

您应该将 logback.xml 添加到您的资源并配置 appender。

并使用以下记录器：

@Service
public class LoginAttemptService {

    private final int MAX_ATTEMPT = 5;

    private LoadingCache<String, Integer> attemptsCache;
    private static Logger loginLogger = LoggerFactory.getLogger("login");

    public void loginSucceeded(String username, String key) {
        attemptsCache.invalidate(key);
        loginLogger.info("Successful login:  " + username + " ip address:" + key);
    }

logback.xml：

<configuration>

    <property name="LOGS_HOME" value="./logs/"/>

    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <layout class="ch.qos.logback.classic.PatternLayout">
            <Pattern>
                %d{yyyy-MM-dd HH:mm:ss} [%thread] %-5level %logger{36} - %msg%n
            </Pattern>
        </layout>
    </appender>

    <appender name="LOGIN-LOG"  class="ch.qos.logback.core.rolling.RollingFileAppender">
        <file>${LOGS_HOME}login.log</file>
        <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
            <Pattern>
                %d{yyyy-MM-dd HH:mm:ss} [%thread] %-5level %logger{36} - %msg%n
            </Pattern>
        </encoder>

        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <!-- rollover daily -->
            <fileNamePattern>${LOGS_HOME}login.%d{yyyy-MM-dd}.%i.log</fileNamePattern>
            <timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
                <maxFileSize>100MB</maxFileSize>
            </timeBasedFileNamingAndTriggeringPolicy>
        </rollingPolicy>
    </appender>

    <logger name="login" level="info" additivity="false">
        <appender-ref ref="LOGIN-LOG"/>
        <appender-ref ref="STDOUT"/>
    </logger>

    <root level="error">
        <appender-ref ref="LOGIN-LOG"/>
        <appender-ref ref="STDOUT"/>
    </root>
</configuration>
