自定义注解——日志
前提：
需要有一个日志表，然后完成日志表的CRUD
然后写自定义注解类
@Target(
{
ElementType.PARAMETER, ElementType.METHOD })
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface Log
{
/** 要执行的操作类型比如：add操作 **/
public String operationType() default "";
/** 要执行的具体操作比如：添加用户 **/
public String operationName() default "";
}
其实只需要一个参数就够了。如果有需要可以吧第一个参数修改为操作等级之类的。第二个参数是操作描述。
然后写个拦截器
搞个拦截器 拦截所有通过控制层的请求。
/**
* @author
* @E-mail: email
* @version 创建时间：
* @desc 切点类
*/
@Aspect
@Component
public class LogInterceptor extends BaseController
{
// 注入Service用于把日志保存数据库
@Resource // 这里我用resource注解，一般用的是@Autowired

最后在控制层的方法上 添加上我们常见的注解就可以了
