- 功能点
（1）申请获取appId和appSecret
（2）通过appId和appSecret获取accessToken
（3）mysql和redis进行key-value键值对存储
（4）对需要的接口url进行请求地址拦截
效果图：
（1）正确的accessToken且没有过期（获取后端数据）
（2）没有填入的accessToken(提示为空)
（3）accessToken正确但是已经过了TTL时间（过期），redis进行数据删除。
（4）默认是7200s
具体实现:

（2）实体类：
package com.coupon_test.coupon.model;
import com.baomidou.mybatisplus.annotation.TableName;
@TableName("m_app")
public class AppEntity {
private long id;
private String appId;
private String appName;
private String appSecret;

（3）mapper层：
package com.coupon_test.coupon.dao;
import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import com.coupon_test.coupon.model.AppEntity;
import org.apache.ibatis.annotations.Param;
import org.apache.ibatis.annotations.Select;

（7）controller层

（8）依赖
<!-- https://mvnrepository.com/artifact/com.alibaba/fastjson -->
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>fastjson</artifactId>
<version>1.2.56</version>
</dependency>
<!--字符串操作-->
<dependency>
<groupId>org.apache.commons</groupId>
<artifactId>commons-lang3</artifactId>
<version>3.2.1</version>
</dependency>
先使用controller获取appId及appSecret, 接着申请accessToken并带至请求中，获取返回数据。
(二)、将请求的http协议改为https
效果图：postman测试
- 首先必须的依赖是
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
- 使用命令获取SSL文件
keytool -genkey -alias tomcat -storetype PKCS12 -keyalg RSA -keysize 2048 -keystore keystore.p12 -validity 3650
application.yml文件配置
server:
port: 8081
ssl:
enabled: true
key-store: classpath:keystore.p12
key-store-type: PKCS12
key-alias: tomcat
key-store-password: caojun
注意是key-store-password
