Learn how to log effectively with Spring Boot. We will look at Spring Boot Starter for Logging. We will look at the defaults in Spring Boot for Logging - Logback and SLF4J. We will also looking at the Spring Boo
该实现检查 classpath 中是否存在 Log4j 2.x API 和 SLF4J 1.7 API,并使用第一个找到的 API 作为日志记录实现,如果 Log4j 2.x 和 SLF4J 都不可用,则使用 Java 平台的核心日志记录工具(也称为 JUL 或 java.util.logging)。 Spring Boot 所有内部日志使用 Commons Logging 来记录,但使底层日志实现是开放的。
@Slf4j @SpringBootApplication public class SpringBoot303LoggingApplication { // private static Logger log = LoggerFactory.getLogger(SpringBoot303LoggingApplication.class); public static void main(String[] args) { SpringApplication.run(SpringBoot303LoggingApplication.class, args); log.info("启动完成")...
class); public static void main(String[] args) { SpringApplication.run(SpringBoot303LoggingApplication.class, args); log.info("启动完成"); } } 方式二:引入 lombok 使用@Slf4j 注解可以自动生成一个 log 对象,省去了手动获取 Logger 对象的步骤,简化了代码编写。 导入依赖: 代码语言:javascript 代码...
使用src\main\resources\application.yml logging: level: root: WARN org: springframework: security: DEBUG web: ERROR hibernate: DEBUG apache: commons: dbcp2: DEBUG 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 2.logging.file Spring Boot 默认把日志输入到console,如果我们要把日志输入到文件中,需...

SpringBoot底层也是使用slf4j+logback的方式进行日志记录; SpringBoot也把其他的日志都替换成了slf4j; Spring Boot能自动适配所有的日志,而且底层使用slf4j+logback的方式记录日志,引入其他框架的时候,只需要把这个框架依赖的日志框架排除掉。 <dependency> <groupId>org.springframework</groupId> ...
