提问by light_ray
I'm using Spring Rest API in server side and jersey API in client side.
我在服务器端使用 Spring Rest API，在客户端使用 jersey API。
I'm creating a screen where it will fetch last 5 customer redeem transaction.
我正在创建一个屏幕，它将获取最后 5 个客户的兑换交易。
From server side i'm returning list of RedeemTransactionDetails and accepting the same in client side.
从服务器端我返回 RedeemTransactionDetails 列表并在客户端接受相同的列表。
I had debugged server side code it's returns the valid list, and in client side response code is 200 , whereas while getting entity i'm getting error from client side.
我调试了服务器端代码，它返回有效列表，在客户端响应代码是 200 ，而在获取实体时，我从客户端收到错误。
Server side:
服务器端：
@RestController
@RequestMapping("/rest/api")
public class CustomerRestController {
@Autowired private CustomerService customerService;
@RequestMapping(value="/redeemTransactionList/{clientId}/{mobileNumber}/{numOfTransaction}" , method=RequestMethod.POST , produces = "application/json; charset=UTF-8")
public @ResponseBody List<RedeemTransactionDetails> redeemTransaction(@PathVariable(value = "clientId") int clientId, @PathVariable(value = "mobileNumber") String mobileNumber , @PathVariable(value="numOfTransaction") int numOfTransaction) {
LOG.debug("We are in redeemTransaction method for user {} " , clientId);
List<RedeemTransactionDetails> redeemList = null ;
try {
redeemList = customerService.redeemTransactionList(clientId, mobileNumber,numOfTransaction);
} catch (Exception e) {
LOG.debug("Excption while fetching redeemTransaction ");
}
return redeemList;
}
}
Client Side :
客户端 ：
public List<RedeemTransactionDetails> getRedeemTransactions(String mobileNumber, String clientId, String numberOfTransaction) {
log.debug("inside authenticate() ");
List<RedeemTransactionDetails> result = null;
try{
webResource = client.resource(uri + "/redeemTransactionList").path(clientId).path(mobileNumber).path(numberOfTransaction) ;
ClientResponse response = webResource.type(MediaType.APPLICATION_JSON).post(ClientResponse.class);
if (response.getStatus() != 200) {
log.debug("response.getStatus() : " + response.getStatus() );
throw new RuntimeException("Failed : HTTP error code : " + response.getStatus());
}
response.getType() ;
result = (List<RedeemTransactionDetails>) response.getEntity(RedeemTransactionDetails.class);
log.debug("user Details " + result);
}
catch(Exception e){
log.debug(e);
}
return result ;
}
}
NOTE: I had used the following dependencies in pom xml file
注意：我在 pom xml 文件中使用了以下依赖项
<dependency>
<groupId>com.sun.jersey</groupId>
<artifactId>jersey-json</artifactId>
<version>1.19.3</version>
</dependency>
<dependency>
<groupId>com.fasterxml.Hymanson.core</groupId>

The error indicates JerseyClient may not have been configured properly to scan Provider packages. Check your web.xml if 'jersey.config.server.provider.packages' property is configured to include 'com.prom.via.rest.dto' package that contains your JAXB classes.
该错误表明 JerseyClient 可能未正确配置以扫描 Provider 包。如果 'jersey.config.server.provider.packages' 属性配置为包含包含 JAXB 类的 'com.prom.via.rest.dto' 包，请检查您的 web.xml。
<servlet-name>Jersey REST Service</servlet-name>
<servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
<!-- Register resources and providers under com.prom.via.rest.dto package. -->
<init-param>
<param-name>jersey.config.server.provider.packages</param-name>
<param-value>com.prom.via.rest.dto</param-value>
</init-param>
</servlet>
Also, as SkyWalker indicated check if RedeemTransactionDetails is annotated with @XmlRootElement annotation or not.
此外，正如 SkyWalker 指出的那样，检查 RedeemTransactionDetails 是否使用 @XmlRootElement 批注进行批注。
