• JDK：java8
• IDE：IDEA
• 項目框架：SpringBoot

項目配置

1. application.yml配置

server:
  port: 6389
  ssl:
    key-store: .keystore
    key-store-type: JKS
    key-alias: alias
    key-store-password: xxxxxxxx
spring:
  datasource:
    driver-class-name: com.mysql.jdbc.Driver
    url: jdbc:mysql://127.0.0.1:3306/xxxxxxx?useUnicode=true&characterEncoding=utf8&useSSL=false
    username: XXXXXX
    password: XXXXXX
#    password: root
  jpa:
    hibernate:
      ddl-auto: update
    show-sql: true
logging:
  path: /opt/modules/logs/qrcode/qrcode.log
file:
  imageWidth: 80  #二維碼logo的寬度
  imageHeight: 80  #二維碼logo的高度
  QRCODE_SIZE: 400  #二維碼尺寸
  logoImagePath: /opt/modules/qrcode/logo/logo.png  #二維碼logo路徑
#  logoImagePath: D:/data/qrcode/logo.png  #二維碼logo路徑
  qrFilePath: /opt/modules/qrcode/  #生成二維碼路徑
#  qrFilePath: D:/data/qrcode/  #生成二維碼路徑
  imagesPath: file:/opt/modules/qrcode/  # 二維碼圖片映射路徑
#  imagesPath: file:D:/data/qrcode/  # 二維碼圖片映射路徑
  imageReturnPath: /images/**

2. 靜態(tài)資源映射（圖片）

import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;

/**

 */
@Configuration
public class WebMvcConf extends WebMvcConfigurerAdapter {

    @Value("${file.imageReturnPath}")
    private String imageReturnPath;
    @Value("${file.imagesPath}")
    private String imagesPath;

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        //imageReturnPath:映射前綴，imagesPath：圖片映射路徑
        registry.addResourceHandler(imageReturnPath).addResourceLocations(imagesPath);
    }
}

3. 本地圖片地址

4. url請求查詢
