Spring Boot 学习 (二) 调用 RESTful Web Service

1. 代码结构
   

2. pom.xml 依赖
   

3. Class 详细
   @JsonIgnoreProperties(ignoreUnknown = true)
   public class Quote {

   private String type;
   private Value value;

   public Quote() {
   }

   @Override
   public String toString() {
   return “Quote{” +
   “type=’” + type + ‘’’ +
   “, value=” + value +
   ‘}’;
   }

   public String getType() {
   return type;
   }

   public void setType(String type) {
   this.type = type;
   }

   public Value getValue() {
   return value;
   }

   public void setValue(Value value) {
   this.value = value;
   }
   }

@JsonIgnoreProperties(ignoreUnknown = true)
public class Value {

private Long id;
private String quote;

public Value() {
}

@Override
public String toString() {
    return "Value{" +
            "id=" + id +
            ", quote='" + quote + '\'' +
            '}';
}

public Long getId() {
    return id;
}

public void setId(Long id) {
    this.id = id;
}

public String getQuote() {
    return quote;
}

public void setQuote(String quote) {
    this.quote = quote;
}

}

4. Application 主程序
   @SpringBootApplication
   public class ApplicationMain {

   private static final Logger log = LoggerFactory.getLogger(ApplicationMain.class);

   public static void main(String[] args) {
   SpringApplication.run(ApplicationMain.class);
   }

   @Bean
   public RestTemplate restTemplate(RestTemplateBuilder builder) {
   return builder.build();
   }

   @Bean
   public CommandLineRunner run(RestTemplate restTemplate) throws Exception {

    consumeRestfulService(restTemplate);
    return null;
   

   }

   private void consumeRestfulService(RestTemplate restTemplate) {
   for (int i = 0; i < 20; i++) {
   Quote quote = restTemplate.getForObject(
   “http://gturnquist-quoters.cfapps.io/api/random”, Quote.class);
   log.info(quote.toString());
   }
   }
   }
