第二十二将 Spring集成RestTemplate消费消息

1.前言

这里主要介绍怎么使用RestTemplate去消费一个服务：http://gturnquist-quoters.cfapps.io/api/random.如果消费成功，会返回一个随机的Json字符串。

2.Spring集成RedisTemplate

2.1 引入依赖:pom.xml

<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId>
</dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope>
</dependency>

2.2 配置RestTemplate：

package com.springboot.resttemplate.config;import org.springframework.boot.web.client.RestTemplateBuilder;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.client.RestTemplate;/*** @Description:* @Author: zrblog* @CreateTime: 2018-10-18 22:57* @Version:v1.0*/
@Configuration
public class RestTemplateConfig {@Beanpublic RestTemplate restTemplate(RestTemplateBuilder builder) {return builder.build();}
}

2.3 测试：Application

package com.springboot.resttemplate;import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;
import org.springframework.web.client.RestTemplate;@SpringBootApplication
public class Application {public static void main(String[] args) {SpringApplication.run(Application.class, args);}@Beanpublic CommandLineRunner run(RestTemplate restTemplate) {return args -> {String resultStr = restTemplate.getForObject("http://gturnquist-quoters.cfapps.io/api/random", String.class);System.out.println(resultStr);};}}
