Question

我使用下面的代码，我将基本http身份验证的凭据设置为使用Spring Security的服务器。不幸的是我对é，ò等特殊字符有问题...我在服务器上收到问号而不是正确的字符有人知道怎么解决吗？我一直在寻找设置编码而没有成功

import org.apache.http.auth.AuthScope;
import org.apache.http.auth.UsernamePasswordCredentials;
import org.apache.http.client.CredentialsProvider;
import org.apache.http.client.HttpClient;
import org.apache.http.impl.client.BasicCredentialsProvider;
import org.apache.http.impl.client.HttpClients;
import org.springframework.http.client.HttpComponentsClientHttpRequestFactory;
import org.springframework.web.client.RestTemplate;

public class RestClient extends RestTemplate { 
   public RestClient(String username, String password) {
         CredentialsProvider credsProvider = new BasicCredentialsProvider();
         credsProvider.setCredentials(
                 new AuthScope(null, -1),
                 new UsernamePasswordCredentials(username, password));
         HttpClient httpClient = HttpClients.custom().setDefaultCredentialsProvider(credsProvider).build();
         setRequestFactory(new HttpComponentsClientHttpRequestFactory(httpClient));
        }
    }

然后我用spring class调用web服务：

RestClient restClient = new RestClient(username, password);
response = restClient.getForObject(addQueryParam(url, queryParams), Response.class);

更新：

使用此代码我有相同的错误（问号而不是特殊字符）。有些想法？

public class RestClient extends RestTemplate {
    private static RestClient instance;

    private RestClient(String username, String password) {
        CredentialsProvider credsProvider = new BasicCredentialsProvider();
        credsProvider.setCredentials(
                new AuthScope(null, -1),
                new UsernamePasswordCredentials(username, password));
        HttpClient httpClient = HttpClients.custom().setDefaultCredentialsProvider(credsProvider).build();
        setRequestFactory(new HttpComponentsClientHttpRequestFactory(httpClient));
    }

    public static synchronized RestClient getInstance(String username, String password){
        if (instance == null){
            instance = new RestClient(username, password);
            instance.getMessageConverters().add(0, new StringHttpMessageConverter(Charset.forName("UTF-8")));
        }
        return instance;

    }  
}

转到您的web.xml并将URIEncoding设置为UTF-8

<Connector port="8080" protocol="HTTP/1.1"
           connectionTimeout="20000"
           redirectPort="8443" 
       URIEncoding="UTF-8"/>


<Connector port="8009" protocol="AJP/1.3" redirectPort="8443" URIEncoding="UTF-8" />

您应该添加正确的邮件转换器在我遇到类似问题的情况下，我使用了这个配置：

RestTemplate rt = new RestTemplate();
rt.getMessageConverters().add(0, new StringHttpMessageConverter(Charset.forName("UTF-8")));

此后一切都很好
