以下是正在触发的包装器 API 代码：-

logger.info("InsIDe Method");
    String integrationUrl=null;
    String integrationUsername = null;
    String integrationpassword = null;
    
        if(StringUtils.isnotBlank(System.getenv("PushGDSDataUrl")))
            integrationUrl = System.getenv("PushGDSDataUrl");
        else
            integrationUrl = "@R_944_10107@s://test.connect.boomi.com/ws/simple/createCommentsx-test";
        
        if(StringUtils.isnotBlank(System.getenv("PushGDSDataUrlUsername")))
            integrationUsername = System.getenv("PushGDSDataUrlUsername");
        else
            integrationUsername = "<integration-username>";
                                   
        
        if(StringUtils.isnotBlank(System.getenv("PushGDSDataUrlPwd")))
            integrationpassword = System.getenv("PushGDSDataUrlPwd");
        else
            integrationpassword = "<integration-password>";
                                   
    
    RestTemplate restTemplate = new RestTemplate();
    @R_944_10107@headers headers = new @R_944_10107@headers();
    headers.setContentType(MediaType.APPliCATION_JsON);
   // headers.set("dcuID",integrationUserName);
    //headers.set("dcpwd",integrationpassword);
  //  headers.set("Content-Type","application/Json");
    
    String auth = integrationUsername + ":" + integrationpassword;
    byte[] encodedAuth = Base64.encodeBase64( 
       auth.getBytes(Charset.forname("US-ASCII")) );
    String authheader = "Basic " + new String( encodedAuth );
    headers.set( "Authorization",authheader );
   // headers.set("Body","{\r\n\"class_name\":\"Server\",\r\n\"company_name:\"ABC\"\r\n}\r\n");
    
    
    GDSPushData newObj = new GDSPushData();
    newObj.setClass_name(className);
    newObj.setCompany_name(companyName);
    
    String Jsoninstring = new Gson().toJson(newObj);
    JsONObject mJsONObject = new JsONObject(Jsoninstring);
    logger.info("request is set");
    
    



    @R_944_10107@entity<String> entityReq = new @R_944_10107@entity<String>(mJsONObject.toString(),headers);
    
    logger.info("request is converted");
    
    
        
         URI targetUrl = UriComponentsBuilder.fromUriString(integrationUrl).build().encode().toUri(); //Build base url
            
            
            logger.info("target Url"+targetUrl);
            
          
            
            ResponseEntity<String> result = restTemplate.exchange(integrationUrl,@R_944_10107@method.POST,entityReq,String.class);
            
            //String result = restTemplate.getForObject(targetUrl,String.class);



            logger.info(result.getStatusCodeValue());
            logger.info(result.getbody());

当我们在指定相同凭据后使用邮递员触发上述代码中提到的 intergation url 时，它工作正常，我们得到 200 OK 响应代码，当从 Spring Java 应用程序触发相同代码时，我们得到 401未经授权的错误。

解决方法

请尝试使用以下代码

@R_944_10107@Client client = @R_944_10107@ClientBuilder.create().build();
@R_944_10107@Post post = new @R_944_10107@Post("<Your_URL>");

 List<NameValuePair> arguments = new ArrayList<>();
arguments.add(new BasicNameValuePair("class_name",className));
arguments.add(new BasicNameValuePair("company_name",companyName));

 try{
String auth = integrationUsername + ":" + integrationpassword;
byte[] encodedAuth = Base64.encodeBase64(
auth.getBytes(Charset.forName("US-ASCII")) );
String authHeader = "Basic " + new String( encodedAuth );

post.setHeader(@R_944_10107@Headers.CONTENT_TYPE,"application/json");
post.setHeader(@R_944_10107@Headers.ACCEPT,"application/json");
post.setHeader(@R_944_10107@Headers.AUTHORIZATION,authHeader);
post.setEntity(new UrlEncodedFormEntity(arguments));
@R_944_10107@Response response = client.execute(post);
