JWT使用 - Spring Security OAuth使用JWT测试_springsecuriyt+jwt 进行单元测试-优快云博客

本文详细介绍了如何在Spring Cloud项目中实现JWT认证，包括引入安全和OAuth2依赖、配置密钥库、创建JWT令牌及验证过程。

第一步：引入依赖

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-security</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-oauth2</artifactId>
</dependency>

第二步：添加keystore到resources文件夹下

位置为：src\main\resources\app.keystore

src\main\resources\publickey.txt

第三步：配置application.yml

encrypt:
  key-store:
    location: classpath:/app.keystore
    secret: app123
    alias: edukey
    password: edu123

第四步：创建测试类，代码如下：

package com.test;

import com.alibaba.fastjson.JSON;
import com.xuecheng.auth.UcenterAuthApplication;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.boot.test.context.SpringBootTest;

import org.springframework.security.jwt.Jwt;
import org.springframework.security.jwt.JwtHelper;
import org.springframework.security.jwt.crypto.sign.RsaSigner;
import org.springframework.security.jwt.crypto.sign.RsaVerifier;
import org.springframework.security.oauth2.provider.token.store.KeyStoreKeyFactory;
import org.springframework.test.context.junit4.SpringRunner;

import javax.servlet.ServletOutputStream;
import javax.sound.midi.Soundbank;
import java.security.KeyPair;
import java.security.interfaces.RSAPrivateKey;
import java.util.HashMap;
import java.util.Map;

/**

        // 获取私钥
        RSAPrivateKey privateKey = (RSAPrivateKey) keyPair.getPrivate();

        // JWT 令牌内容
