日志工具介绍

java中的日志工具主要包含三种log4j、logging、logback，springboot中默认使用logback

配置文件 application.properties

## 打印SQL语句##SpringBoot默认是使用info级别，没有指定级别的就用Springboot默认规定的级别：root级别logging.level.com.test.mapper.master=debug#该属性用来配置日志文件名，如果该属性不配置，默认文件名为spring.loglogging.file=/var/log/test.log#指定控制台日志的输出格式，自定义logging.pattern.console=%date %level [%thread] %logger{10} [%file:%line] - %msg%n#指定文件中日志的输出格式，自定义logging.pattern.file=%msg%n

需要打印日志的类

public class EsController {    private final static Logger logger = LoggerFactory.getLogger(EsController.class);        @Autowired    private RestHighLevelClient client;        @RequestMapping(value = "/log", method = RequestMethod.GET)    public void logTest() {        String taskName = "task_上线20190105HttpInvoker_测试环境";        Map
   
     oneCase = new HashMap<>();        oneCase.put("taskName",taskName);        oneCase.put("interfaceType","HttpInvoker");        oneCase.put("env","test"); // 初始设计没有区分环境        oneCase.put("masterservicename","UmeFlightStatus");        oneCase.put("servicefactory_getmethod_subservicename","getWeatherSVC");        oneCase.put("servicemethod","getAeroalm");        oneCase.put("result","failed");        String case1 = JSON.toJSONString(oneCase);                logger.info(taskName+"|"+case1);    }}
