我想使用javax.ws.rs.core.Response来发送和接收Card实体对象.但我不知道如何将内容转换回Card对象.
我的testCreate()方法应该执行create(Card card)方法,接收json并将其转换为card对象.但我总是得到类型不匹配或它说getEntity()方法不能像这样执行:response.getEntity(Card.class).
有没有人知道我如何正确处理响应,以便我可以将返回的json实体再次转换为Card对象?
这是我的CardResource方法:
@POST
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_JSON)
public Response create(Card card) {
Card c = dao.create(card);
if(c.equals(null)) {
return Response.status(Status.BAD_REQUEST).entity("Create failed!").build();
}
return Response.status(Status.OK)
.entity(c)
.type(MediaType.APPLICATION_JSON)
.build();
}
在这里我的CardResourceTests类
@Test
public void testCreate() {
boolean thrown = false;
CardResource resource = new CardResource();
Card c = new Card(1, "Cardname", "12345678", 1, 1,
"cardname.jpg", new Date(), new Date());
try {
Response result = resource.create(c);
System.out.println(result.getEntity(Card.class)); // not working!!!
if(result.getStatus() != 200) {
thrown = true;
}
} catch(Exception e) {
e.printStackTrace();
thrown = true;
}
assertEquals("Result", false, thrown);
}
在这里我的Card.class
@XmlRootElement

public Boolean getValid() {

public void setValid(Boolean valid) {

}
在这里我的CardDAO课程
public class CardDAO {
private final static Logger logger = Logger.getLogger(CardDAO.class.getName());
public Card create(Card card) {
PersistenceManager pm = PMF.get().getPersistenceManager();
Card c = new Card(card.getId(), card.getName(), card.getCode(),
card.getCardProviderId(), card.getCodeTypeId(), card.getPicturePath(),
new Date(), new Date());
try {
pm.makePersistent(c);
} catch(Exception e) {
logger.severe("Create failed: " + e.getMessage());
return null;
} finally {
pm.close();
}
return c;
}
}
解决方法:
我不确定调用带注释的Web服务方法就像使用params的简单方法一样.尝试从CardResource类中删除所有注释,并像调用类方法一样调用此方法.
