        <dependency>
            <groupId>com.tencentcloudapi</groupId>
            <artifactId>tencentcloud-sdk-java-ocr</artifactId>
            <version>LATEST</version>
        </dependency>

 2 yml配置如下

tencent:
  cloud:
    secretId: AKIDfBwSxKSKyOl24sRkARUUMzTkmYPxxxxx
    secretKey: 3tVs0tY0FG3bs0tWt1uZzKTOxxxxxxxx
    region: ap-beijing

3 属性注入

import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;
 
@Data
@Component
@ConfigurationProperties(prefix = "tencent.cloud")
public class TencentCloudProperties {
 
    private String secretId;
    private String secretKey;
    private String region;
 
}
