在SpringBoot中配置日志级别和输出格式的教程详解

logging.level.root=INFO

import org.slf4j.LoggerFactory;
import org.springframework.core.env.Environment;
public class MyService {
    private static final org.slf4j.Logger logger = LoggerFactory.getLogger(MyService.class);
    private Environment environment;
    public MyService(Environment environment) {
        this.environment = environment;
        configureLogging();
    }
    private void configureLogging() {
        String level = environment.getProperty("logging.level.root");
        if (level != null) {
            ch.qos.logback.classic.Logger logger = (ch.qos.logback.classic.Logger) LoggerFactory.getLogger(Logger.ROOT_LOGGER_NAME);
            logger.setLevel(ch.qos.logback.classic.Level.valueOf(level));
        }
    }
}

logging.pattern.console=%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n

import org.slf4j.LoggerFactory;
import org.springframework.core.env.Environment;
public class MyService {
    private static final org.slf4j.Logger logger = LoggerFactory.getLogger(MyService.class);
    private Environment environment;
    public MyService(Environment environment) {
        this.environment = environment;
        configureLogging();
    }
    private void configureLogging() {
        String pattern = environment.getProperty("logging.pattern.console");
        if (pattern != null) {
            ch.qos.logback.classic.Logger logger = (ch.qos.logback.classic.Logger) LoggerFactory.getLogger(Logger.ROOT_LOGGER_NAME);
            logger.getAppender("Console").setEncoder(createPatternEncoder(pattern));
        }
    }
    private PatternLayoutEncoder createPatternEncoder(String pattern) {
        PatternLayoutEncoder encoder = new PatternLayoutEncoder();
        encoder.setPattern(pattern);
        encoder.setContext((LoggerContext) LoggerFactory.getILoggerFactory());
        encoder.start();
        returnencoder;
    }
}
