Logger

Type: Interface | Module: microsphere-java-core | Package: io.microsphere.logging | Since: 1.0.0

Source: microsphere-java-core/src/main/java/io/microsphere/logging/Logger.java

Overview

Logger interface for logging messages with different severity levels.

The Logger provides methods to log messages at various levels such as TRACE, DEBUG, INFO, WARN, and ERROR. Each level has corresponding methods to check if the level is enabled (isXxxEnabled()) and to log messages either as simple strings, formatted strings, or with associated exceptions.

Example Usage

Basic Usage

`if (logger.isInfoEnabled()) {
    logger.info("Application started successfully.");
`
}

Formatted Logging

`String user = "JohnDoe";
int attempts = 3;
logger.warn("User '{`' exceeded maximum login attempts: {}", user, attempts);
}

Logging Exceptions

`try {
    // some operation that may fail
` catch (Exception e) {
    logger.error("An error occurred during processing", e);
}
}

Conditional Logging

`if (logger.isDebugEnabled()) {
    logger.debug("Detailed debug information: {`", generateDebugData());
}
}

Declaration
