当添加新的依赖项时，Spring无法从String转换为rsappublickey / rsprivvatekey.&l

Question

我有一个使用Spring Security的微服务，我在应用程序中有私钥和公钥的内容。Yml(请不要评判我)。我还有一个带有这些属性的@ConfigurationProperties文件。服务工作得很好，内部rsakeyconverversionservicepostprocessor分别从String转换到rsappublickey/rsprivvatekey。

问题是，当我在pom.xml中添加flyway-core依赖时。Spring无法进行转换。这个微服务不是我的，所以我不能把键从属性移到文件并从那里读取它。

你知道会发生什么事吗?

application.yml

lorem:
ipsum:
dolor:
jwt:
private-key: |
-----BEGIN PRIVATE KEY-----
...
-----END PRIVATE KEY-----
public-key: |
-----BEGIN PUBLIC KEY-----
...
-----END PUBLIC KEY-----

房地产类

@ConfigurationProperties(prefix = "lorem.ipsum.dolor.jwt")
@Component
class SecurityProperties {
private RSAPrivateKey privateKey;
private RSAPublicKey publicKey;
}

似乎由于某种原因没有加载属性转换器。我认为这是Spring Boot自动配置中的错误。

如果你想立即解决它，那么你可以自己实现转换器。只需使用相同的Spring类。

像这样:

package lorem.ipsum.dolor.sitamet;
import org.springframework.boot.context.properties.ConfigurationPropertiesBinding;
import org.springframework.core.convert.converter.Converter;
import org.springframework.security.converter.RsaKeyConverters;
import org.springframework.stereotype.Component;
import java.io.ByteArrayInputStream;
import java.security.interfaces.RSAPrivateKey;
@Component
@ConfigurationPropertiesBinding
public class MyPrivateKeyConverter implements Converter<String, RSAPrivateKey> {
@Override
public RSAPrivateKey convert(String from) {
return RsaKeyConverters.pkcs8().convert(new ByteArrayInputStream(from.getBytes()));
}
}

package lorem.ipsum.dolor.sitamet;
import org.springframework.boot.context.properties.ConfigurationPropertiesBinding;
import org.springframework.core.convert.converter.Converter;
import org.springframework.security.converter.RsaKeyConverters;
import org.springframework.stereotype.Component;
import java.io.ByteArrayInputStream;
import java.security.interfaces.RSAPublicKey;
@Component
@ConfigurationPropertiesBinding
public class MyPublicKeyConverter implements Converter<String, RSAPublicKey> {
@Override
public RSAPublicKey convert(String from) {
return RsaKeyConverters.x509().convert(new ByteArrayInputStream(from.getBytes()));
}
}

同样，您不需要在pom.xml中指定flyway-core的版本。继承自spring-boot-starter-parent
