SpringBoot如何使用Template请求http接口

<!-- 如果你使用Maven -->  
<dependency>  
    <groupId>org.springframework.boot</groupId>  
    <artifactId>spring-boot-starter-web</artifactId>  
</dependency>  
<!-- 或者如果你只需要spring-web -->  
<dependency>  
    <groupId>org.springframework.boot</groupId>  
    <artifactId>spring-web</artifactId>  
</dependency>

import org.springframework.context.annotation.Bean;  
import org.springframework.context.annotation.Configuration;  
import org.springframework.web.client.RestTemplate;  
@Configuration  
public class RestClientConfig {  
    @Bean  
    public RestTemplate restTemplate() {  
        return new RestTemplate();  
    }  
}

import org.springframework.beans.factory.annotation.Autowired;  
import org.springframework.stereotype.Service;  
import org.springframework.web.client.RestTemplate;  
@Service  
public class MyHttpClientService {  
    @Autowired  
    private RestTemplate restTemplate;  
    public String getSomeData() {  
        String url = "http://example.com/api/data";  
        return restTemplate.getForObject(url, String.class);  
    }  
    // 也可以发送POST请求等  
    public String postSomeData(String url, MyData data) {  
        return restTemplate.postForObject(url, data, String.class);  
    }  
}
