1、添加操作日志注解及其切面类，实现保存操作日志的功能

src/main/java/com/cmeeting/annotation/OperLog.java

+package com.cmeeting.annotation;
+
+
+import java.lang.annotation.*;
+
+@Target({ElementType.METHOD})
+@Retention(RetentionPolicy.RUNTIME)
+@Documented
+public @interface OperLog {
+
+    // 操作界面
+    String location();
+
+    // 操作记录
+    String operation();
+}

src/main/java/com/cmeeting/aspect/OperLogAspect.java

+package com.cmeeting.aspect;
+
+import com.cmeeting.ad.entity.RobotSecurityUser;
+import com.cmeeting.ad.util.SecurityUtil;
+import com.cmeeting.annotation.OperLog;
+import com.cmeeting.pojo.OperationLog;
+import com.cmeeting.service.OperationLogService;
+import lombok.extern.slf4j.Slf4j;
+import org.aspectj.lang.JoinPoint;
+import org.aspectj.lang.annotation.Aspect;
+import org.aspectj.lang.annotation.Before;
+import org.springframework.beans.factory.annotation.Autowired;
+import org.springframework.stereotype.Component;
+
+
+@Aspect
+@Slf4j
+@Component
+public class OperLogAspect {
+
+    @Autowired
+    private OperationLogService operationLogService;
+
+    @Before(value = "@annotation(operLog)")
+    public void before(JoinPoint point, OperLog operLog) {
+
+        RobotSecurityUser user = SecurityUtil.getUser();
+
+        String location = operLog.location();
+        String operation = operLog.operation();
+
+        OperationLog operationLog = new OperationLog();
+        operationLog.setLocation(location);
+        operationLog.setOperation(operation);
+        operationLog.setUserId(user.getId());
+        operationLog.setUserName(user.getUsername());
+
+        operationLogService.save(operationLog);
+    }
+}
