• 一、創(chuàng)建日志記錄表、異常日志表，表結(jié)構(gòu)如下：
• 二、添加Maven依賴
• 三、創(chuàng)建操作日志注解類OperLog.java
• 四、創(chuàng)建切面類記錄操作日志
• 五、在Controller層方法添加@OperLog注解
• 六、操作日志、異常日志查詢功能

平時(shí)我們?cè)谧鲰?xiàng)目時(shí)經(jīng)常需要對(duì)一些重要功能操作記錄日志，方便以后跟蹤是誰(shuí)在操作此功能；我們?cè)诓僮髂承┕δ軙r(shí)也有可能會(huì)發(fā)生異常，但是每次發(fā)生異常要定位原因我們都要到服務(wù)器去查詢?nèi)罩静拍苷业剑乙膊荒軐?duì)發(fā)生的異常進(jìn)行統(tǒng)計(jì)，從而改進(jìn)我們的項(xiàng)目，要是能做個(gè)功能專門來(lái)記錄操作日志和異常日志那就好了， 當(dāng)然我們肯定有方法來(lái)做這件事情，而且也不會(huì)很難，我們可以在需要的方法中增加記錄日志的代碼，和在每個(gè)方法中增加記錄異常的代碼，最終把記錄的日志存到數(shù)據(jù)庫(kù)中。聽起來(lái)好像很容易，但是我們做起來(lái)會(huì)發(fā)現(xiàn)，做這項(xiàng)工作很繁瑣，而且都是在做一些重復(fù)性工作，還增加大量冗余代碼，這種方式記錄日志肯定是不可行的。

我們以前學(xué)過(guò)Spring 三大特性，IOC（控制反轉(zhuǎn)），DI（依賴注入），AOP（面向切面），那其中AOP的主要功能就是將日志記錄，性能統(tǒng)計(jì)，安全控制，事務(wù)處理，異常處理等代碼從業(yè)務(wù)邏輯代碼中劃分出來(lái)。今天我們就來(lái)用springBoot Aop 來(lái)做日志記錄，好了，廢話說(shuō)了一大堆還是上貨吧。

一、創(chuàng)建日志記錄表、異常日志表，表結(jié)構(gòu)如下：

二、添加Maven依賴

1?<dependency>
2?????<groupId>org.springframework.bootgroupId>
3?????<artifactId>spring-boot-starter-aopartifactId>
4?dependency>

三、創(chuàng)建操作日志注解類OperLog.java

?1?package?com.hyd.zcar.cms.common.utils.annotation;
?2
?3?import?java.lang.annotation.Documented;
?4?import?java.lang.annotation.ElementType;
?5?import?java.lang.annotation.Retention;
?6?import?java.lang.annotation.RetentionPolicy;
?7?import?java.lang.annotation.Target;
?8
?9?/**
10??*?自定義操作日志注解
11??*?@author?wu
12??*/
13?@Target(ElementType.METHOD)?//注解放置的目標(biāo)位置,METHOD是可注解在方法級(jí)別上
14?@Retention(RetentionPolicy.RUNTIME)?//注解在哪個(gè)階段執(zhí)行
15?@Documented
16?public?@interface?OperLog?{
17?????String?operModul()?default?"";?//?操作模塊
18?????String?operType()?default?"";??//?操作類型
19?????String?operDesc()?default?"";??//?操作說(shuō)明
20?}

四、創(chuàng)建切面類記錄操作日志
