Spring AOP 操作日誌實現

一、註解

 * 日誌註解類
 * 使用方式 @Log(value="某某接口方法")  @Log(ignore=true)

@Documented
@Target(ElementType.METHOD) //只能在方法上使用此註解
@Retention(RetentionPolicy.RUNTIME)
public @interface Log {

    /**
     * 日誌描述，這裏使用了@AliasFor 別名:spring提供的
     * @return
     */
    @AliasFor("value")
    String value() default "";

    /**
     * 是否不記錄日誌
     * @return
     */
    boolean ignore() default false;
