我正在使用一个用纯 java 编写的代码的 jar。所以这个 jar 中没有创建任何 bean。现在我创建了一个 Spring Boot 应用程序，我在我的应用程序中使用了这个 jar。我正在尝试创建 bean 并自动装配外部 jar 的类。以下是我正在创建 bean 的类：
@Configuration
public class AppConfig {
@Bean
public RestTemplate restTemplate() {
return new RestTemplate();
}
@Bean
public ICommonDataService iCommonDataService() {
ICommonDataService iCommonDataService = new CommonDataService();
((CommonDataService) iCommonDataService).setCommonDAO(ICommonDAO());
return iCommonDataService;
}
@Bean
public ICommonDAO ICommonDAO() {
return new CommonDAO();
}
}
我也在尝试为 Spring Boot 的 RestTemplate 类创建 bean。
但是当我尝试使用这些 bean 时，我得到了空指针异常。
以下是我使用这些 bean 的应用程序：
@Service
public class AuditServiceClientImpl implements AuditServiceClient {
@Autowired
private ICommonDataService iCommonDataService;
@Autowired
private RestTemplate restTemplate;
public AuditServiceResponse postAsyncRequestData(AuditServiceLog auditServiceLog) throws Exception {
return post(AuditServiceConstants.ASYNC_REQUEST_DATA, auditServiceLog, false);
}
public AuditServiceResponse postSyncRequestData(AuditServiceLog auditServiceLog) throws Exception {
return post(AuditServiceConstants.SYNC_REQUEST_DATA, auditServiceLog, true);
}
public AuditServiceResponse postAsyncResponseData(AuditServiceLog auditServiceLog) throws Exception {
return post(AuditServiceConstants.ASYNC_RESPONSE_DATA, auditServiceLog, false);
}
public AuditServiceResponse postSyncResponseData(AuditServiceLog auditServiceLog) throws Exception {
return post(AuditServiceConstants.SYNC_RESPONSE_DATA, auditServiceLog, true);
}
private AuditServiceResponse post(String endpoint, AuditServiceLog auditServiceLog, boolean synchronous) throws Exception {
String methodName = "AuditServiceLogWriter";
AuditServiceResponse auditServiceResponse = null;
String baseUrl = iCommonDataService.getEnvValue(0, 0, AuditServiceConstants.AUDIT_SERVICE_BASE_URL);
String sslKeystore = iCommonDataService.getEnvValue(0, 0, AuditServiceConstants.SSL_KEYSTORE);
String sslKeystorePassword = iCommonDataService.getEnvValue(0, 0, AuditServiceConstants.SSL_KEYSTORE_PASSWORD);
String sslKeystoreType = iCommonDataService.getEnvValue(0, 0, AuditServiceConstants.SSL_KEYSTORE_TYPE);
MultiValueMap<String, String> headers = new LinkedMultiValueMap<String, String>();
headers.add("X-AGS-Client-Name", "test");
headers.add("X-AGS-Group-Name", "test");
headers.add("Content-Type", "application/json");
restTemplate.getMessageConverters().add(new MappingJackson2HttpMessageConverter());
HttpEntity<AuditServiceLog> request = new HttpEntity<AuditServiceLog>(auditServiceLog, headers);
try {
auditServiceResponse = restTemplate.postForObject(baseUrl + endpoint, request, AuditServiceResponse.class);
} catch (Exception e) {
CDISIServiceLogging.log(CDISIServiceLogging.INFO, getClass().getName(), methodName, e.getMessage(),
"Seems there is some error while posting the log to audit servivce");
if (synchronous)
throw new Exception(e);
}
return auditServiceResponse;
}
public ICommonDataService getICommonDataService() {
return iCommonDataService;
}
public void setICommonDataService(ICommonDataService iCommonDataService) {
this.iCommonDataService = iCommonDataService;
}
public RestTemplate getRestTemplate() {
return restTemplate;
}
public void setRestTemplate(RestTemplate restTemplate) {
this.restTemplate = restTemplate;
}
}
有人可以帮忙吗，我在这里找不到问题。任何帮助表示赞赏。
主类：
@SpringBootApplication
public class Application extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
