Question

我正在尝试为我的spring boot项目设置基本的Auth。到目前为止，我已经做到了：

com.app.apitool.RESTConsumer 软件包中的

CallAPI.java

public class CallAPI {

RestTemplate restTemplate = new RestTemplate();

@Autowired
RestTemplateBuilder restTemplateBuilderObj;

@Autowired
BasicAuthSetup basicAuthObj;

@Autowired
RestOperations rest;

String endpointURL = "";

public String pingAPi() {
    HttpEntity<String> request = new HttpEntity<String>(basicAuthObj.getHeaders());

    ResponseEntity<String> response = rest.exchange(endpointURL, HttpMethod.GET, request, String.class);

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

com.app.apitool.HTTPAuthSetup 软件包中的

BasicAuthSetup.java

@Component
public class BasicAuthSetup {
private String plainCreds = "id@account1:password";
private String base64Creds = Base64.getEncoder().encodeToString(plainCreds.getBytes());

@Bean
public HttpHeaders getHeaders() {
    HttpHeaders headers = new HttpHeaders();
    headers.add("Authorization", "Basic" + base64Creds);
    System.out.println("Auth created: "+headers);
    return headers;
}                  
}

运行时，出现以下异常：

申请无法开始

说明：

com.appd.apitool.RESTConsumer.CallAPI中的字段休息需要一个Bean   键入“ org.springframework.web.client.RestOperations”，该值不能为   找到。

操作：

考虑定义一个类型的bean   配置中的“ org.springframework.web.client.RestOperations”。

我搜索了此错误，遇到了类似的问题（{如果不是相同的话）here，我正在跟踪提到的解决方法here。

我之所以决定创建新刊物，是因为在第一个链接的文章中没有看到任何解决方案。另外，我是spring-boot框架的新手。

com.app.apitool 软件包中的主要 App.java ：

@SpringBootApplication
@RestController
public class App {

private static final Logger log = org.slf4j.LoggerFactory.getLogger(App.class);


@Autowired
private CallAPI callAPIobj;

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

@RequestMapping("/api")
public String testAPI() {
    return callAPIobj.pingAPi();
}

}

好的，因此在您的Maven项目中，基本的auth设置将是您进行bean配置的好地方：

BasicAuthSetup.java：

package com.app.apitool.config;

import com.fasterxml.jackson.databind.ObjectMapper;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.HttpEntity;
import org.springframework.http.HttpHeaders;
import org.springframework.http.converter.json.MappingJackson2HttpMessageConverter;
import org.springframework.web.client.RestTemplate;

import java.util.Base64;

@Configuration
public class BasicAuthSetup {

    private static final String plainCreds = "id@account1:password";
    private static final  String base64Creds = Base64.getEncoder().encodeToString(plainCreds.getBytes());

    @Bean
    public HttpHeaders getHeaders() {

        HttpHeaders headers = new HttpHeaders();
        headers.add("Authorization", "Basic" + base64Creds);

        return headers;
    }

    @Bean
    public RestTemplate restTemplate() {

        RestTemplate restTemplate = new RestTemplate();
        MappingJackson2HttpMessageConverter converter = new MappingJackson2HttpMessageConverter();
        converter.setObjectMapper(new ObjectMapper());
        restTemplate.getMessageConverters().add(converter);

        return restTemplate;
    }

    @Bean
    public HttpEntity<String> stringHttpEntity() {
        return new HttpEntity<>(getHeaders());
    }
}

然后，在/ src / main / java下的适当包中创建一个测试类，如下所示：

CallAPITest.java：

package com.app.apitool;

import com.app.apitool.config.BasicAuthSetup;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.HttpEntity;
import org.springframework.http.HttpMethod;
import org.springframework.http.ResponseEntity;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.web.client.RestOperations;

import static org.junit.Assert.assertNotNull;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = BasicAuthSetup.class)
public class CallAPITest {

    private static final String endpointURL = "";

    @Autowired
    private RestOperations rest;

    @Autowired
    private HttpEntity<String> stringHttpEntity;

    @Test
    public void pingAPi() {

        ResponseEntity<String> response = rest.exchange(endpointURL, HttpMethod.GET, stringHttpEntity, String.class);

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

        final String responseBody = response.getBody();

        assertNotNull(responseBody);
    }
}

以下是您在Maven pom.xml中需要的依赖项（根据您的喜好更改版本）：

    <jackson.version>2.9.6</jackson.version>
    <spring.version>4.3.5.RELEASE</spring.version>

找不到RestOperations bean
