日志管理-aop

日志管理操作一般分为aop和拦截器两种，我做的是aop，但用aop有一个缺点，在做复杂登录验证上是无法获得登录的用户id

自定义注解

 * 自定义日志注解 * @author biling */@Target({ElementType.PARAMETER, ElementType.METHOD})@Retention(RetentionPolicy.RUNTIME)@Documentedpublic @interface ServiceLog {    /**     * 日志类型     * @return     */     String logType() default "";    /**     * 日志内容     * @return     */     String logContent() default "";}

在service层加上自定义的注解

 @Transactional    @Override    **@ServiceLog(logType = "1",logContent = "添加漏洞白名单")**    public ResultBO<Void> add(List<WhiteAddForm> adf,Long id){        for (int i = 0 ; i < adf.size() ; i++){            White white = new White();            WhiteAddForm whiteAddForm = adf.get(i);            white.setAssets_id(whiteAddForm.getId());            white.setVul(whiteAddForm.getName());            white.setVul_type(whiteAddForm.getType());            white.setCompany_id(id);            whiteMapper.insertSelective(white);        }        return new ResultBO<Void>(SUCCESS);    }
