How to use logging with Spring Boot?

Comment

We can use logging with Spring Boot by specifying log levels on the application.properties file. 
Spring Boot loads this file when it exists in the classpath and it can be used to configure both Spring Boot and application code.
Spring Boot, by default, includes spring-boot-starter-logging as a transitive dependency for the spring-boot-starter module.
By default, Spring Boot includes SLF4J along with Logback implementations.
If Logback is available, Spring Boot will choose it as the logging handler. 
You can easily configure logging levels within the application.properties file without having to create logging provider-specific configuration files such as logback.xml or log4j.properties.

logging in spring boot

Comment

// pom.xml
// If you are using spring-boot-starter-web, logging is automatically included with "spring-boot-starter-logging" jar

// application.properties
logging.level.org.springframework=debug // everything else will print as debug level
logging.level.[com.package.name]=trace // only this package will print as trace level

// Controlller
@Controller
public class SayHelloController {
    private Logger logger = LoggerFactory.getLogger(getClass());
	@RequestMapping("say-hello-jsp")
	// @RequestParam lets the url take a value as argument to a parameter payload
	// "ModelMap"  helps to pass data from controller to the specified view
	public String sayHelloJsp(@RequestParam(value="name", required = false)String name, ModelMap model){ 
		model.put("name",name); // the name variable now can be accessed in the view with "name" keyword
        // what you want to log
        System.out.println(name); // This is NOT RECOMMENDED in prod environment
        logger.debug(name); // debug level logging
        logger.info("This will print on info level"); // info level logging
        logger.warn("This will print on warn level"); // warn level logging
        logger.trace("This will print on trace level"); // warn level logging
		return "sayHello"; // the jsp file name
	}

Lombok has annotations for that.
Annotate your class with @Slf4j and a static log fiedl will be generated.
