之前写了一篇JWT的随笔, 还没有写springboot 整合 token, 前几天晚上忙着抽空重构代码, 就简单的重构了下方法, 类. 还有if else, + 设计模式, +泛型没整. 等周末有时间再整整. 其实理解了jwt流程, 整合进springboot就相对于来说较简单了. 依赖加下, 拦截器加下, 代码加下. 话不多说, 上代码
pom.xml 依赖
<!-- jwt--> <dependency> <groupId>io.jsonwebtoken</groupId> <artifactId>jjwt</artifactId> <version>0.9.0</version> </dependency> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <optional>true</optional> </dependency>
application.properties 配置
##jwt配置 # 代表这个JWT的接收对象,存入audience audience.clientId= # 密钥, 经过Base64加密, 可自行替换 audience.base64Secret== # JWT的签发主体，存入issuer audience.name= # 过期时间，时间戳 audience.expiresSecond=
