在application.properties中配置 logging.level.com.umgsai.core.dal=debug 可以在日志中打印出详细的SQL语句。

但是并不希望在线上环境也打印，此时需要在线上和线下配置不同的日志级别。

@Slf4j@Servicepublic class DynamicLoggersConfig {     private static final String DAL_PACKAGE = "com.umgsai.core.dal";    @Value("${logging.level.com.umgsai.core.dal:info}")    private String dalLogLevel = "info";     @ApolloConfig    private Config config;    private final static String LoggerTag = "logging.level.";    private final LoggingSystem loggingSystem;     public DynamicLoggersConfig(LoggingSystem loggingSystem) {        Assert.notNull(loggingSystem, "LoggingSystem must not be null");        this.loggingSystem = loggingSystem;    }     @ApolloConfigChangeListener    private void configChangeListener(ConfigChangeEvent changeEvent) {        Set
   
     keyNames = config.getPropertyNames();        for (String key : keyNames) {            if (StringUtils.containsIgnoreCase(key, LoggerTag)) {                String strLevel = config.getProperty(key, "info");                LogLevel level = LogLevel.valueOf(strLevel.toUpperCase());                loggingSystem.setLogLevel(key.replace(LoggerTag, ""), level);            }            log.info("{}:{}", key, config.getProperty(key, null));        }    }     @PostConstruct    private void setLogLevel() {        LogLevel level = LogLevel.valueOf(dalLogLevel.toUpperCase());        loggingSystem.setLogLevel(DAL_PACKAGE, level);        log.info("{}:{}", DAL_PACKAGE, dalLogLevel);    }}
