本地应用注入iDME注解示例

示例场景

对于拥有本地应用的用户，在本地安装SDK后，只需要在启动类中注入@ComponentScan(basePackages = {"com.huawei.innovation"})注解，运行启动类即可。

操作步骤

package com.singzai;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.CompinentScan;

@SpringBootApplication
@ComponentScan(basePackages = {"com.huawei.innovation"})
public class MainApplication{
     public static void main(String[] args) { SpringApplication.run(MainApplication.class, args); }
}

异常处理

在启动类注入iDME注解并运行启动类时，本地调试可能会提示如下错误：

java.security.cert.CertificateException: No subject alternative DNS name matching xxx found

您可以参考如下操作进行修复。

1. 在项目中创建一个类，并添加RestTemplateBuilder和RestTemplate方法。
2. 分别在RestTemplateBuilder和RestTemplate方法上注入bean。

   例如，您在“src/main/java/com/xdm/configuration/”路径下创建“RestTemplateConfiguration.java”，其示例代码如下：

   package com.xdm.configuration;
   
   import org.apache.http.conn.ssl.NoopHostnameVerifier;
   import org.apache.http.impl.client.CloseableHttpClient;
   import org.apache.http.impl.client.HttpClients;
   import org.springframework.boot.web.client.RestTemplateBuilder;
   import org.springframework.context.annotation.Bean;
   import org.springframework.context.annotation.Configuration;
   import org.springframework.http.client.HttpComponentsClientHttpRequestFactory;
   import org.springframework.web.client.RestTemplate;
   
   import javax.net.ssl.SSLContext;
   import javax.net.ssl.TrustManager;
   import javax.net.ssl.X509TrustManager;
   import java.security.KeyManagementException;
   import java.security.NoSuchAlgorithmException;
   import java.security.cert.X509Certificate;
   
   @Configuration
   public class RestTemplateConfiguration {
   
       @Bean
       public RestTemplateBuilder restTemplateBuilder() {
           return new RestTemplateBuilder();
       }
   
       @Bean
       public RestTemplate restTemplate(RestTemplateBuilder builder) throws NoSuchAlgorithmException, KeyManagementException {
   
           TrustManager[] trustAllCerts = new TrustManager[] {
                   new X509TrustManager() {
                       public java.security.cert.X509Certificate[] getAcceptedIssuers() {
                           return new X509Certificate[0];
                       }
                       public void checkClientTrusted(
                               java.security.cert.X509Certificate[] certs, String authType) {
                       }
                       public void checkServerTrusted(
                               java.security.cert.X509Certificate[] certs, String authType) {
                       }
                   }
           };
           SSLContext sslContext = SSLContext.getInstance("SSL");
           sslContext.init(null, trustAllCerts, new java.security.SecureRandom());
           CloseableHttpClient httpClient = HttpClients.custom()
                   .setSSLContext(sslContext)
                   .setSSLHostnameVerifier(NoopHostnameVerifier.INSTANCE)
                   .build();
           HttpComponentsClientHttpRequestFactory customRequestFactory = new HttpComponentsClientHttpRequestFactory();
           customRequestFactory.setHttpClient(httpClient);
           return builder.requestFactory(() -> customRequestFactory).build();
       }
   
   }

3. 在操作步骤添加的@ComponentScan注解中，添加1创建的类的扫描路径。

   package com.singzai;
   
   import org.springframework.boot.SpringApplication;
   import org.springframework.boot.autoconfigure.SpringBootApplication;
   import org.springframework.context.annotation.CompinentScan;
   
   @SpringBootApplication
   @ComponentScan(basePackages = {"com.huawei.innovation","com.xdm"})
   public class MainApplication{
        public static void main(String[] args) { SpringApplication.run(MainApplication.class, args); }
   }
