SpringBoot整合日志管理
1.1使用log4j记录日志
1.1.2新建log4j配置文件
文件名称log4j.properties
|
#log4j.rootLogger=CONSOLE,info,error,DEBUG log4j.rootLogger=info,error,CONSOLE,DEBUG log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout log4j.appender.CONSOLE.layout.ConversionPattern=%d{yyyy-MM-dd-HH-mm} [%t] [%c] [%p] - %m%n log4j.logger.info=info log4j.appender.info=org.apache.log4j.DailyRollingFileAppender log4j.appender.info.layout=org.apache.log4j.PatternLayout log4j.appender.info.layout.ConversionPattern=%d{yyyy-MM-dd-HH-mm} [%t] [%c] [%p] - %m%n log4j.appender.info.datePattern='.'yyyy-MM-dd log4j.appender.info.Threshold = info log4j.appender.info.append=true #log4j.appender.info.File=/home/admin/pms-api-services/logs/info/api_services_info log4j.appender.info.File=/Users/dddd/Documents/testspace/pms-api-services/logs/info/api_services_info log4j.logger.error=error log4j.appender.error=org.apache.log4j.DailyRollingFileAppender log4j.appender.error.layout=org.apache.log4j.PatternLayout log4j.appender.error.layout.ConversionPattern=%d{yyyy-MM-dd-HH-mm} [%t] [%c] [%p] - %m%n log4j.appender.error.datePattern='.'yyyy-MM-dd log4j.appender.error.Threshold = error log4j.appender.error.append=true #log4j.appender.error.File=/home/admin/pms-api-services/logs/error/api_services_error log4j.appender.error.File=/Users/dddd/Documents/testspace/pms-api-services/logs/error/api_services_error log4j.logger.DEBUG=DEBUG log4j.appender.DEBUG=org.apache.log4j.DailyRollingFileAppender log4j.appender.DEBUG.layout=org.apache.log4j.PatternLayout log4j.appender.DEBUG.layout.ConversionPattern=%d{yyyy-MM-dd-HH-mm} [%t] [%c] [%p] - %m%n log4j.appender.DEBUG.datePattern='.'yyyy-MM-dd log4j.appender.DEBUG.Threshold = DEBUG log4j.appender.DEBUG.append=true #log4j.appender.DEBUG.File=/home/admin/pms-api-services/logs/debug/api_services_debug log4j.appender.DEBUG.File=/Users/dddd/Documents/testspace/pms-api-services/logs/debug/api_services_debug

1.2使用AOP统一处理Web请求日志
1.2.1POM文件新增依赖
|
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-aop</artifactId> </dependency> |
1.2.2POM文件新增依赖
|
@Aspect @Component public class WebLogAspect {
private static final Logger logger = LoggerFactory.getLogger(WebLogAspect.class);
@Pointcut("execution(public * com.itmayiedu.controller.*.*(..))") public void webLog() { }
@Before("webLog()") public void doBefore(JoinPoint joinPoint) throws Throwable { // 接收到请求，记录请求内容 ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes(); HttpServletRequest request = attributes.getRequest(); // 记录下请求内容 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:{},value:{}", name, request.getParameter(name)); } }
@AfterReturning(returning = "ret", pointcut = "webLog()") public void doAfterReturning(Object ret) throws Throwable { // 处理完请求，返回内容 logger.info("RESPONSE : " + ret); } } |
1.3Spring Boot集成lombok让代码更简洁
1.3.1添加lombok依赖
|
<dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> </dependency> |
1.3.2实体类演示
|
@Slf4j @Data public class UserEntity { // @Getter // @Setter private String userName; // @Getter // @Setter private Integer age;
@Override public String toString() { return "UserEntity [userName=" + userName + ", age=" + age + "]"; }
public static void main(String[] args) { UserEntity userEntity = new UserEntity(); userEntity.setUserName("zhangsan"); userEntity.setAge(20); System.out.println(userEntity.toString()); log.info("####我是日志##########"); }
} |
1.3.2其他特性
|
@Data 标签，生成getter/setter toString()等方法 @NonNull : 让你不在担忧并且爱上NullPointerException @CleanUp : 自动资源管理：不用再在finally中添加资源的close方法 @Setter/@Getter : 自动生成set和get方法 @ToString : 自动生成toString方法 @EqualsAndHashcode : 从对象的字段中生成hashCode和equals的实现 @NoArgsConstructor/@RequiredArgsConstructor/@AllArgsConstructor 自动生成构造方法 @Data : 自动生成set/get方法，toString方法，equals方法，hashCode方法，不带参数的构造方法 @Value : 用于注解final类 @Builder : 产生复杂的构建器api类 @SneakyThrows : 异常处理（谨慎使用） @Synchronized : 同步方法安全的转化 @Getter(lazy=true) : @Log : 支持各种logger对象，使用时用对应的注解，如：@Log4 |
