无法找到内容类型application / json的MessageBodyReader并输入int

Question

我有一个主要项目，我现在必须测试... 我做了第二个项目，在那个项目中，我粘贴了主项目中的接口和实体，现在我做了一个简单的jUnit测试用例... 看起来像这样：

public class TestLogin {

String path = "http://localhost:8080/rest/dss"; //thats the right path...
ResteasyClient client = new ResteasyClientBuilder().build();
ResteasyWebTarget rtarget = client.target(path);
DssRest rest = rtarget.proxy(DssRest.class);

@Test
public void test() {
    assert(rest.login(null, "Test", "Test") != -1);
}

}

DssRest，界面

@POST
@Produces(MediaType.APPLICATION_JSON)
@Path("/login/{userName}/{password}")
int login(@Context HttpServletRequest req, @PathParam("userName") String userName,
        @PathParam("password") String password);

从那里我去DssBean，那里的功能是我想测试

@Override
public int login(HttpServletRequest req, String userName, String password) {
    ResteasyClient client = new ResteasyClientBuilder().build();
    ResteasyWebTarget rtarget = client.target(".../rest/mw"); //real path
    MWRest rest = rtarget.proxy(MWRest.class);
    int userId = rest.login(userName, password);
    ...
    return userId; //it always is > -1

}

从那里，我调用MWRest，我的第二个项目的接口......并且该项目具有相同的功能，返回INT，12例如...

现在....测试一下，制作了一个junit测试套件

@RunWith(Suite.class)
@SuiteClasses({TestLogin.class})
public class AllTests {

}

在我运行之前，我确定，我需要测试的2个项目正在运行... 然后我运行套件，作为jUnit测试，并在JUnit控制台上，出现此错误，我根本无法弄清楚。

我希望你能帮助...... thx
