java - 将 Spring Boot 1.x 升级到 2.x(如果使用 {cipher} 文本，则更新 ENCRYPT KEY VM 参数)

Question

如果您的 spring-boot 应用程序属性文件中使用了 {cipher} 加密文本。

application.yml 或 application.properties

my.password='{cipher}68e78a954bfa0297ecc733`

上面是 SpringBoot2 中的启动失败，并显示错误消息无法解密:key=my.password

Spring-boot-1

以下任何一个 VM 参数都可以有效提供 key ，以便 spring 在加载属性时可以解密'{cipher}f75146b2d391aa6'。

1. 加密 key (默认 key )
2. 加密 key
3. 加密 key
4. 加密 key
5. 加密 key
6. ENCRYPT_KEY
7. 加密 key

Spring 使用 org.springframework.boot.bind.RelaxedPropertyResolver 解析上述 key 来获取 key ，但该类已在 spring-boot-2 中被弃用并删除>.

来自 org.springframework.cloud.bootstrap.encrypt.EncryptionBootstrapConfiguration 类的 spring-cloud-context-1.x.jar 中的代码片段

Environment environment = context.getEnvironment();
RelaxedPropertyResolver propertyResolver = new RelaxedPropertyResolver(environment);
hasProperty(propertyResolver, environment, "encrypt.key");

private boolean hasProperty(RelaxedPropertyResolver propertyResolver, Environment environment, String key) {
        String value = propertyResolver.getProperty(key);
        if (value == null) {
            return false;
        }
        return StringUtils.hasText(environment.resolvePlaceholders(value));
    }

Spring-boot-2

只有 encrypt.key 是传递 key 的有效 VM 参数。

来自 org.springframework.cloud.bootstrap.encrypt.EncryptionBootstrapConfiguration 类的 spring-cloud-context-2.x.jar 中的代码片段

Environment environment = context.getEnvironment();
hasProperty(environment, "encrypt.key");

private boolean hasProperty(Environment environment, String key) {
            String value = environment.getProperty(key);
            if (value == null) {
                return false;
            }
            return StringUtils.hasText(environment.resolvePlaceholders(value));
        }
