配置resttemplate

import org.springframework.context.annotation.Bean;

import org.springframework.context.annotation.Configuration;

import org.springframework.http.client.ClientHttpRequestFactory;

import org.springframework.http.client.SimpleClientHttpRequestFactory;

import org.springframework.web.client.RestTemplate;

/**

 * RestTemplate配置类

 */

@Configuration

public class RestTemplateConfig {

    @Bean

    public RestTemplate restTemplate(ClientHttpRequestFactory factory){

        return new RestTemplate(factory);

    }

    @Bean

    public ClientHttpRequestFactory simpleClientHttpRequestFactory(){

        SimpleClientHttpRequestFactory factory = new SimpleClientHttpRequestFactory();

        factory.setReadTimeout(5000);//单位为ms

        factory.setConnectTimeout(5000);//单位为ms

        return factory;

    }

}

在controller中调用

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.http.*;

import org.springframework.web.bind.annotation.GetMapping;

import org.springframework.web.bind.annotation.RestController;

import org.springframework.web.client.RestTemplate;

import org.apache.commons.codec.binary.Base64;

@RestController

public class IndexController {

    @Autowired

    private RestTemplate restTemplate;

    @GetMapping("basicauth")

    public void getBasicAuth(){

        String user = "111";

        String password = "66666";

        String userMsg = user + ":" + password;

        String base64UserMsg = Base64.encodeBase64String(userMsg.getBytes());

        System.out.println();

        System.out.println(base64UserMsg);

        String url = "http://host:port/api";

        String postBody = "data";

        HttpHeaders headers = new HttpHeaders();

        headers.add("User-Agent", "Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; rv:11.0) like Gecko");

        headers.add("Authorization ", base64UserMsg);

        HttpEntity<String> entity = new HttpEntity<String>(postBody, headers);

        ResponseEntity<String> response = restTemplate.postForEntity(url, entity, String.class);

        System.out.println(response.getBody());

    }

}

启动Springboot项目

import org.springframework.boot.Banner;

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication

public class App {

    public static void main(String[] args) {

        SpringApplication app = new SpringApplication(App.class);

        //关闭banner

        app.setBannerMode(Banner.Mode.OFF);

        app.run(args);

    }

}
