导入打印日志，aop，hutool，的依赖，Hutool是一个Java工具包，里面封装了大量的常用工具类，到时候咱们就通过这个工具包中有一个工具类可以用来获取客户端IP地址。
<dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId></dependency>
<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-aop</artifactId></dependency><dependency><groupId>cn.hutool</groupId><artifactId>hutool-all</artifactId><version>5.6.3</version></dependency>
自定义操作类型枚举类 因为基本是增删改查四个方法
/*** 操作类型枚举类* @author lichuan*/public enum OperationTypeEnum {/*** 新增操作*/INSERT("新增"),/*** 修改操作*/UPDATE("修改"),/*** 删除操作*/DELETE("删除"),/*** 查询操作*/QUERY("查询"),/*** 其它*/OTHER("其它");private String operationType;OperationTypeEnum(String operationType) {this.operationType = operationType;}public String getOperationType() {return operationType;}}
自定义用来记录用户操作日志的注解
@Target(ElementType.METHOD) //注解放置的目标位置,METHOD是可注解在方法级别上@Retention(RetentionPolicy.RUNTIME) //注解在哪个阶段执行@Documentedpublic @interface OperationLog {/*** 操作模块* @return*/String operationModule() default "";/*** 操作类型* @return*/OperationTypeEnum operationType() default OperationTypeEnum.OTHER;/*** 操作说明* @return*/String description() default "";}
写一个方法加上我们自定义的注解
定义用来记录用户操作日志的切面类
import cn.hutool.extra.servlet.ServletUtil;import com.fasterxml.jackson.databind.ObjectMapper;import lombok.extern.slf4j.Slf4j;import org.aspectj.lang.ProceedingJoinPoint;import org.aspectj.lang.annotation.Around;import org.aspectj.lang.annotation.Aspect;import org.aspectj.lang.annotation.Pointcut;import org.aspectj.lang.reflect.MethodSignature;import org.ponent;import org.springframework.web.context.request.RequestAttributes;import org.springframework.web.context.request.RequestContextHolder;import javax.servlet.http.HttpServletRequest;import java.lang.reflect.Method;import java.util.HashMap;import java.util.Map;/*** @author lichuan*/@Aspect@Component@Slf4jpublic class OperationLogAspect {/*** 设置操作日志切入点，在注解的位置切入代码*/@Pointcut("execution(public * com.tm.controller..*Controller.*(..))")public void operationLogPointCut() {}/*** 定义环绕通知* 1. 环绕通知需要携带ProceedingJoinPoint类型的参数* 2. 环绕通知类似于动态代理的全过程ProceedingJoinPoint类型的参数可以决定是否执行目标方法* 3. 且环绕通知必须有返回值，返回值即目标方法的返回值*/@Around("operationLogPointCut()")public Object around(ProceedingJoinPoint joinPoint) {Object result = null;//获取系统当前时间毫秒值long beginTime = System.currentTimeMillis();log.info("环绕通知开始");try {//执行目标方法result = joinPoint.proceed();} catch (Throwable e) {e.printStackTrace();}//获取系统当前时间毫秒值long endTime = System.currentTimeMillis();// 获取RequestAttributesRequestAttributes requestAttributes = RequestContextHolder.getRequestAttributes();// 从获取RequestAttributes中获取HttpServletRequest的信息HttpServletRequest request = (HttpServletRequest) requestAttributes.resolveReference(RequestAttributes.REFERENCE_REQUEST);//获取ipString clientIP = ServletUtil.getClientIP(request);log.info(clientIP);//获取目标方法执行时间long usageTime = endTime - beginTime;// operationLogEntity.setUsageTime(usageTime);try {// 从切面织入点处通过反射机制获取织入点处的方法MethodSignature signature = (MethodSignature) joinPoint.getSignature();// 获取切入点所在的方法Method method = signature.getMethod();//System.out.println(method);// 获取操作OperationLog operationLog = method.getAnnotation(OperationLog.class);if (operationLog != null) {log.info(operationLog.operationModule());log.info(operationLog.description());log.info(operationLog.operationType().getOperationType());}// 获取请求的类名String className = joinPoint.getTarget().getClass().getName();// 获取请求的方法名String methodName = method.getName();methodName = className + "." + methodName;log.info(methodName);// 请求方法// operationLogEntity.setMethodName(methodName);// 请求的参数Map<String, String> parameterMap = ServletUtil.getParamMap(request);// 将参数所在的数组转换成jsonString requestParams = new ObjectMapper().writeValueAsString(parameterMap);// 请求参数System.out.println(parameterMap);log.info(requestParams);// 返回结果log.info(new ObjectMapper().writeValueAsString(result));// 请求URLlog.info(request.getRequestURL().toString());// 请求URIlog.info(request.getRequestURI());// 创建时间// operationLogEntity.setCreateTime(new Date());// System.out.println(operationLogEntity);log.info("环绕通知结束");} catch (Exception e) {}return result;}/*** 转换request 请求参数* @param parameterMap request获取的参数数组*/public Map<String, String> convertParameterMap(Map<String, String[]> parameterMap) {Map<String, String> convertParameterMap = new HashMap<>();for (String key : parameterMap.keySet()) {convertParameterMap.put(key, parameterMap.get(key)[0]);}return convertParameterMap;}}
6.测试
调用test方法，可以看到控制台已经打印出了日志信息，创建表的对象存入即可
