一、数据库

/*
    Schema：test
    Info：测试数据库
    Date：2022/09/07 13:49:38
*/
-- 1、创建数据库
CREATE
DATABASE `test` CHARACTER SET 'utf8' COLLATE 'utf8_general_ci';

-- 2、创建表
DROP TABLE IF EXISTS `user`;
CREATE TABLE `user`
(
    `id`   bigint(11) NOT NULL AUTO_INCREMENT,
    `name` varchar(10) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL,
    PRIMARY KEY (`id`) USING BTREE
) ENGINE = InnoDB AUTO_INCREMENT = 5 CHARACTER SET = utf8 COLLATE = utf8_general_ci ROW_FORMAT = Dynamic;

-- 3、插入数据
INSERT INTO `user`
VALUES (1, '赵');
INSERT INTO `user`
VALUES (2, '钱');
INSERT INTO `user`
VALUES (3, '孙');
INSERT INTO `user`
VALUES (4, '李');

二、项目

参考代码： 【gitee】https://gitee.com/xiaoxianwansui/springboot-request-limit.git

1、pom.xml：引入核心依赖

        
        <dependency>
            <groupId>org.springframework.bootgroupId>
            <artifactId>spring-boot-starter-webartifactId>

            <artifactId>lombokartifactId>
            <optional>trueoptional>
        dependency>

2、application.yml：配置数据源

3、RequestLimit.java：定义注解

4、RequestLimitAspect.java：定义AOP切面

5、RequestLimitException.java：定义注解异常

6、Application.java：使用@EnableAspectJAutoProxy注解

7、UserController.java：使用@RequestLimit注解

三、启动

四、测试

1、正常返回结果

http://127.0.0.1:8888/user/list

2、抛出异常信息

http://127.0.0.1:8888/user/list
