在resources资源目录下创建一个application.properties的配置文件,内容如下

server.port=8989

创建授权参数

在/src/main/java/com/edurt/sli/slisj目录下创建param目录,并在该目录下新建JwtParam文件

* http://www.apache.org/licenses/LICENSE-2.0 *

校验授权

在控制台输入以下命令(未授权时)

curl -X GET 'http://localhost:8989/auth/hello'

会出现以下错误信息

{
  "timestamp": "2019-11-26T13:05:05.204+0000",
  "status": 403,
  "error": "Forbidden",
  "message": "Access Denied",
  "path": "/auth/hello"
}

提示我们未授权,这时我们使用/auth/login去获得授权的token

curl -X POST 'http://127.0.0.1:8989/auth/login' --header 'Content-Type: application/json' -d '{"username": "admin", "password": "password"}'

返回以下token信息

eyJhbGciOiJIUzUxMiJ9.eyJzdWIiOiJhZG1pbiIsImV4cCI6MTU3NTIwNTg4OH0.zc3JTsIHIZSmi-hrgCB1AKrrjVWtnWB4YJjOhzml2k9qRdTGdoDYKM1XriQIAInvIrTDDkpozT4Ny58Wcpm4JA

这时我们使用返回的token进行访问/auth/hello接口获取数据

curl -X GET 'http://127.0.0.1:8989/auth/hello' --header 'Authorization: eyJhbGciOiJIUzUxMiJ9.eyJzdWIiOiJhZG1pbiIsImV4cCI6MTU3NTIwNTg4OH0.zc3JTsIHIZSmi-hrgCB1AKrrjVWtnWB4YJjOhzml2k9qRdTGdoDYKM1XriQIAInvIrTDDkpozT4Ny58Wcpm4JA'

返回以下信息

Hello Jwt!!!

此时我们已经完成JWT授权配置

打包文件部署

打包数据

mvn clean package -Dmaven.test.skip=true -X

运行打包后的文件即可

java -jar target/spring-learn-integration-security-jwt-1.0.0.jar
