Java框架：Spring Boot ：日誌處理

SpringBoot + 整合Log4j

• 1.屏蔽SpringBoot的logging

• <!-- 排除springboot自帶的logging 日誌-->
  <dependency>
  	<groupId>org.springframework.boot</groupId>
  	<artifactId>spring-boot-starter</artifactId>
  	<exclusions>
  		<exclusion>
  			<groupId>org.springframework.boot</groupId>
  			<artifactId>spring-boot-starter-logging</artifactId>
  		</exclusion>
  	</exclusions>
  </dependency>

• 2.添加log4j

• <!-- 添加log4j -->
  <!-- SpringBoot下的Log4j的最新版本爲1.3.8 -->
  <dependency>
  	<groupId>org.springframework.boot</groupId>
  	<artifactId>spring-boot-starter-log4j</artifactId>
  	<version>1.3.8.RELEASE</version>
  </dependency>

• 3.resources/log4j.properties文件創建並配置

  log4j.rootLogger=INFO,Console,File
  log4j.appender.Console=org.apache.log4j.ConsoleAppender
  log4j.appender.Console.Target=System.out
  log4j.appender.Console.layout = org.apache.log4j.PatternLayout
  log4j.appender.Console.layout.ConversionPattern=[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c - %L]%m%n
  log4j.appender.File = org.apache.log4j.RollingFileAppender
  #設置日誌輸出路徑
  log4j.appender.File.File = C:/Users/JinChao/Desktop/sbtest/logs/info.log
  log4j.appender.File.MaxFileSize = 10MB
  log4j.appender.File.Threshold = ALL
  log4j.appender.File.layout = org.apache.log4j.PatternLayout
  log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c - %L]%m%n
  

•  4.測試：在controller中用下

  @RestController
  @RequestMapping("user")
  public class UserController {
  
      Logger logger=Logger.getLogger(UserController.class);
  
      @Autowired
      private IUserService iUserService;
  
      @RequestMapping("add")
      @ResponseBody
      public String add() {
          String username = "zjc1";
          String password = "zjc1234";
          logger.info("sasdaad"+username);
          iUserService.add(username, password);
          return "SUCCESS";
      }
  }

•  5.結果在桌面指定文件夾有日誌文件，內容爲

  ......................省略.....................
  [INFO] [2019-10-29 01:03:28][org.springframework.web.servlet.DispatcherServlet - 489]FrameworkServlet 'dispatcherServlet': initialization started
  [INFO] [2019-10-29 01:03:28][org.springframework.web.servlet.DispatcherServlet - 508]FrameworkServlet 'dispatcherServlet': initialization completed in 27 ms
  [INFO] [2019-10-29 01:03:28][com.zjc.web.controller.UserController - 24]sasdaadzjc1

 SpringBoot + AOP處理Web請求日誌

• 前提：log4j導入，在上面的基礎上
• 1.添加AOP依賴

• <!-- AOP -->
  <dependency>
  	<groupId>org.springframework.boot</groupId>
  	<artifactId>spring-boot-starter-aop</artifactId>
  </dependency>

• 2.aspect/創建切面類：僅供參考

• @Aspect
  @Component//配置bean
  public class WebLogAspect {
  
      private Logger logger = Logger.getLogger(getClass());
      
  	//切入點掃描所有controller的所有方法
      @Pointcut("execution(public * com.zjc.web.controller..*.*(..))")
      public void webLog() {    }
  
      @Before("webLog()")
      public void doBefore(JoinPoint joinPoint) throws Throwable {
          // 接收到請求，記錄請求內容
          ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
          HttpServletRequest request = attributes.getRequest();
          // 記錄請求內容
          logger.info("---------------request----------------");
          logger.info("URL : " + request.getRequestURL().toString());
          logger.info("HTTP_METHOD : " + request.getMethod());
          logger.info("IP : " + request.getRemoteAddr());
          Enumeration<String> enu = request.getParameterNames();
          while (enu.hasMoreElements()) {
              String name = (String) enu.nextElement();
              logger.info("name:" + name + "value" + request.getParameter(name));
          }
      }
  
      @AfterReturning(returning = "ret", pointcut = "webLog()")
      public void doAfterReturning(Object ret) throws Throwable {
          logger.info("---------------response----------------");
          // 處理完請求，返回內容
          logger.info("RESPONSE : " + ret);
      }
  
  }

  3.在App中配置切面類掃描路徑
• @ComponentScan(basePackages = {"....",.....,"com.zjc.aspect"})
