springboot系列五 logback 日志配置 颜色渲染控制台日志

最简单的日志配置

在application.yml中添加debug模式日志：

debug: true

启动项目后发现会打印很多日志。springboot默认是debug=false

默认日志配置是在org.springframework.boot.context.logging.LoggingApplicationListener类中的。

static {
        MultiValueMap loggers = new LinkedMultiValueMap();
        loggers.add("web", "org.springframework.core.codec");
        loggers.add("web", "org.springframework.http");
        loggers.add("web", "org.springframework.web");
        loggers.add("sql", "org.springframework.jdbc.core");
        loggers.add("sql", "org.hibernate.SQL");
        DEFAULT_GROUP_LOGGERS = Collections.unmodifiableMap(loggers);
        loggers = new LinkedMultiValueMap();
        loggers.add(LogLevel.DEBUG, "sql");
        loggers.add(LogLevel.DEBUG, "web");
        loggers.add(LogLevel.DEBUG, "org.springframework.boot");
        loggers.add(LogLevel.TRACE, "org.springframework");
        loggers.add(LogLevel.TRACE, "org.apache.tomcat");
        loggers.add(LogLevel.TRACE, "org.apache.catalina");
        loggers.add(LogLevel.TRACE, "org.eclipse.jetty");
        loggers.add(LogLevel.TRACE, "org.hibernate.tool.hbm2ddl");
        LOG_LEVEL_LOGGERS = Collections.unmodifiableMap(loggers);
        EVENT_TYPES = new Class[]{ApplicationStartingEvent.class, ApplicationEnvironmentPreparedEvent.class, ApplicationPreparedEvent.class, ContextClosedEvent.class, ApplicationFailedEvent.class};
        SOURCE_TYPES = new Class[]{SpringApplication.class, ApplicationContext.class};
        shutdownHookRegistered = new AtomicBoolean(false);
    }

使用logback配置日志

在src/main/resources下新建文件 /logs/logback.xml，内容(控制台带颜色渲染)：

    logback
    
    

    
    
        
            INFO
        
        true
        
            
            
            --------------> %red(%d{yyyy-MM-dd HH:mm:ss}) %green([%thread]) %highlight(%-5level) %boldMagenta(%logger) - %cyan(%msg%n)
            UTF-8
        
    

    
    
        ${log.path}/main.log
        
            
            ${log.path}/main.log%d{yyyy-MM-dd HH:mm}.log
            30
            1GB
        
        
            
            --------------> %d{yyyy-MM-dd HH:mm:ss} [%thread] %-5level %logger{36} - %msg%n
            UTF-8
        
    

    
        
        
    

application.yml中添加日志配置：

logging:
  config: classpath:log/logback.xml

写一个测试接口：

@SpringBootApplication
@RestController
@Slf4j
public class LogApp {
    public static void main(String[] args) {
        SpringApplication.run(LogApp.class, args);
    }

    @GetMapping("/")
    public String home(){
        log.info("访问了主页接口");
        return "hello world!";
    }
}

启动项目后，访问 localhost:8080 ,查看控制台和文件
