Description:

Field restTemplate in com.mundo.DemoEurekaConsumerApplication required a bean of type 'org.springframework.web.client.RestTemplate' that could not be found.

The injection point has the following annotations:
	- @org.springframework.beans.factory.annotation.Autowired(required=true)


Action:

Consider defining a bean of type 'org.springframework.web.client.RestTemplate' in your configuration.

【解决方法】：

在 Spring Boot 项目启动类 xxxApplication 中，设置手动引入 RestTemplate 相关配置，代码如下：

    @Bean
    @LoadBalanced
    RestTemplate restTemplate(){
        return new RestTemplate();
    }

然后在别的类中注入，启动就不会报错了，如：

public class TestService {
	@Autowired
	private RestTemplate restTemplate;
	public void service() {
		restTemplate.getForObject("", String.class);
	}
}
