SpringBoot Security整合JWT授权RestAPI

本教程主要详细讲解SpringBoot Security整合JWT授权RestAPI。

基础环境

技术	版本
Java	1.8+
SpringBoot	2.x.x
Security	5.x
JWT	0.9.0

创建项目

• 初始化项目

mvn archetype:generate -DgroupId=com.edurt.sli.slisj -DartifactId=spring-learn-integration-security-jwt -DarchetypeArtifactId=maven-archetype-quickstart -Dversion=1.0.0 -DinteractiveMode=false

• 修改pom.xml增加security和jwt的支持

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
