micronaut 安全中的自定义 JWT 过期

Question

JWT的过期时间可以通过配置micronaut.security.token.jwt.generator.access-token-expiration来设置。

是否可以为单独发行的 JWT 令牌设置自定义值？搜索文档我没有找到任何有用的信息，除非您可以将 BearerTokenRenderer 和 return 替换为自定义响应。

    public AccessRefreshToken render(Integer expiresIn, String accessToken, @Nullable String refreshToken) {
    return new AccessRefreshToken(accessToken, refreshToken, BEARER_TOKEN_TYPE, ***customValue**);
}

在这种情况下 return 为 expires_in 设置不同的值是否可行？

Answer 1

根据 micronaut documentation - pt 9.3.5

您可以将 ClaimGenerator 替换为您自己的： ClaimGenerator

其中有一个带参数的方法Integer expiration

您可以使用 @Replaces 注释替换类，如下所述：

希望能解决您的问题

解决方案是扩展 JwTClaimsSet 生成器

    private final TokenConfiguration tokenConfiguration;
    private final JwtIdGenerator jwtIdGenerator;
    private final ClaimsAudienceProvider claimsAudienceProvider;
    private final String appName;

    /**
     * @param tokenConfiguration       Token Configuration
     * @param jwtIdGenerator           Generator which creates unique JWT ID

    public CustomClaimsGenerator(TokenConfiguration tokenConfiguration,@Nullable JwtIdGenerator jwtIdGenerator, @Nullable ClaimsAudienceProvider claimsAudienceProvider, ApplicationConfiguration applicationConfiguration) {
