b. 编写resources/META-INF/spring.factories

org.springframework.boot.autoconfigure.EnableAutoConfiguration=\ com.woniuxy.tool.KuaiDiNiaoAutoConfiguration

c. 编写自动配置类和配置属性类
```java
package com.woniuxy.tool;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
@Configuration
@EnableConfigurationProperties(KuaiDiNiaoProperties.class)
public class KuaiDiNiaoAutoConfiguration {
    private final KuaiDiNiaoProperties properties;
    public KuaiDiNiaoAutoConfiguration(KuaiDiNiaoProperties properties) {
        this.properties = properties;
    }
    @Bean
    public KuaiDiNiaoQueryAPI kuaiDiNiaoQueryAPI(){
        KuaiDiNiaoConfig config =new KuaiDiNiaoConfig();
        config.setUserKey(this.properties.getUserKey());
        config.setUserSecret(this.properties.getUserSecret());
        config.setReqURL(this.properties.getReqURL());
        return new KuaiDiNiaoQueryAPI(config);
    }
}
----
package com.woniuxy.tool;
import org.springframework.boot.context.properties.ConfigurationProperties;
@ConfigurationProperties(prefix = "kuaidiniao")
public class KuaiDiNiaoProperties {
    private String userKey;
    private String userSecret;
    private String reqURL;
    public String getUserKey() {
        return userKey;
    }
    public void setUserKey(String userKey) {
        this.userKey = userKey;
    }
    public String getUserSecret() {
        return userSecret;
    }
    public void setUserSecret(String userSecret) {
        this.userSecret = userSecret;
    }
    public String getReqURL() {
        return reqURL;
    }
    public void setReqURL(String reqURL) {
        this.reqURL = reqURL;
    }
}

d. mvn clean install

1. 在demo56使用kuaidiniao-spring-boot-starter

   1. 引入kuaidiniao的starter依赖

   2. 配置application.yml

      kuaidiniao:
      user-key: 1663793
      user-secret: 0d253737-fc22-4064-87cd-5052fc6af857
      req-u-r-l: http://api.kdniao.com/Ebusiness/EbusinessOrderHandle.aspx

      c. 引入并直接使用

      @Autowired
      private KuaiDiNiaoQueryAPI kuaiDiNiaoQueryAPI;
      @GetMapping("query")
      public String query(String expCode,String expNo) throws Exception {
        return kuaiDiNiaoQueryAPI.getOrderTracesByJson(expCode,expNo);
      }

      ```java package com.woniuxy.tool;

import java.io.*; import java.net.HttpURLConnection; import java.net.URL; import java.net.URLEncoder; import java.security.MessageDigest; import java.util.HashMap; import java.util.Map;
