一、问题的出现
最近在使用RestTemplate发送请求的时候,出现了这样的一个问题:
sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
通过搜索原因,发现是RestTemplate发送该https请求,需要附带上证书去请求(目前看应该是客户端单向的要求,不带也行,只需客户端配置,服务端不强求)。
解决方案:
1、在使用RestTemplate发送请求的时候,如果发送的是https请求,并且该请求需要证书认证时,那么就通过配置RestTemplate,忽略https证书认证,直接发送请求。
2、可以把证书下载下来,这种操作比较复杂,这里不做这种方法的描述。
二、前期准备
该项目是maven项目,由于配置RestTemplate的部分使用类来自于apache的一些jar包,在开始配置前先导入如下jar包:
<!--定制请求跳过ssl证书验证-->
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpclient</artifactId>
</dependency>
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpmime</artifactId>
</dependency>
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpcore</artifactId>
</dependency>
<!--定制请求跳过ssl证书验证-->
jar包版本根据需求选择。
三、RestTemplate配置
/**
* RestTemplate配置类
*/
@Slf4j
@Configuration
public class RestTemplateConfig {
/**
* 忽略Https证书认证RestTemplate
* @return unSSLRestTemplate
*/
@Bean("unSSLRestTemplate")
public RestTemplate unSSLRestTemplate() throws UnSSLRestTemplateCreateException {
try{
RestTemplate restTemplate = new RestTemplate(RestTemplateConfig.generateHttpRequestFactory());
return restTemplate;
}catch (Exception e){
log.error(e.getMessage());
throw new UnSSLRestTemplateCreateException("unSSLRestTemplate bean创建失败,原因为:" + e.getMessage());
}
}
/**
* 通过该工厂类创建的RestTemplate发送请求时,可忽略https证书认证
* @return 工厂
*/
private static HttpComponentsClientHttpRequestFactory generateHttpRequestFactory() throws Exception{
TrustStrategy acceptingTrustStrategy = ((x509Certificates, authType) -> true);
SSLContext sslContext = SSLContexts.custom().loadTrustMaterial(null, acceptingTrustStrategy).build();
SSLConnectionSocketFactory connectionSocketFactory = new SSLConnectionSocketFactory(sslContext, new NoopHostnameVerifier());
HttpClientBuilder httpClientBuilder = HttpClients.custom();
httpClientBuilder.setSSLSocketFactory(connectionSocketFactory);
CloseableHttpClient httpClient = httpClientBuilder.build();
HttpComponentsClientHttpRequestFactory factory = new HttpComponentsClientHttpRequestFactory();
factory.setHttpClient(httpClient);
return factory;
}
}
