### 统一日志处理 ###

#### 依赖 ####

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

#### 注解 ####

import java.lang.annotation.ElementType;
    import java.lang.annotation.Retention;
    import java.lang.annotation.RetentionPolicy;
    import java.lang.annotation.Target;
    
    /**
     * 日志注解
     */
    @Target({
         ElementType.METHOD })
    @Retention(RetentionPolicy.RUNTIME)
    public @interface LogAnnotation {
        
    	String module() default "";
    }

#### 处理 ####

import org.aspectj.lang.ProceedingJoinPoint;
    import org.aspectj.lang.annotation.Around;
    import org.aspectj.lang.annotation.Aspect;
    import org.aspectj.lang.reflect.MethodSignature;
    import org.springframework.util.StringUtils;
    
    
    /**
     * 统一日志处理
     */
    @Aspect
    @Component
    public class LogAdvice {
        
    
    	@Autowired
    	private SysLogService logService;
    
    	@Around(value = "@annotation(com.wuxian.annotation.LogAnnotation)")
    	public Object logSave(ProceedingJoinPoint joinPoint) throws Throwable {
        
    		SysLogs sysLogs = new SysLogs();
    		MethodSignature methodSignature = (MethodSignature) joinPoint.getSignature();
    		System.out.println(1);
    		String module = null;
    		LogAnnotation logAnnotation = methodSignature.getMethod().getDeclaredAnnotation(LogAnnotation.class);
    		module = logAnnotation.module();
    		if (StringUtils.isEmpty(module)) {
        
    			ApiOperation apiOperation = methodSignature.getMethod().getDeclaredAnnotation(ApiOperation.class);
    			if (apiOperation != null) {
        
    				module = apiOperation.value();
    			}
    		}
    
    		if (StringUtils.isEmpty(module)) {
        
    			throw new RuntimeException("没有指定日志module");
    		}
    		sysLogs.setModule(module);
    
    		try {
        
    			Object object = joinPoint.proceed();
    
    			sysLogs.setFlag(true);
    			logService.save(sysLogs);
    
    			return object;
    		} catch (Exception e) {
        
    			sysLogs.setFlag(false);
    			sysLogs.setRemark(e.getMessage());
    			logService.save(sysLogs);
    			throw e;
    		}
    
    	}
    }

#### 使用 ####

@RestController
    @RequestMapping("/humiditys")
    public class HumidityController {
        
    
    
        @LogAnnotation
        @ApiOperation(value = "湿度")
        @PostMapping("/switch/{alert_value}")
        public ResponseInfo switchHumidity(@PathVariable Long alert_value) {
        
            // .......
        }
    }
