Question

override func viewDidLoad() {
    super.viewDidLoad()
    let label = UILabel()

    let myMutableString = NSMutableAttributedString()

    //right-to-left
    let multipleAttributes: [String : AnyObject] = [
        NSForegroundColorAttributeName: UIColor.orangeColor(),
        NSBackgroundColorAttributeName: UIColor.blueColor(),
        NSUnderlineStyleAttributeName: NSUnderlineStyle.StyleDouble.rawValue,
        NSWritingDirectionAttributeName : [NSWritingDirection.LeftToRight.rawValue ]
    ]

    let myAttrString = NSAttributedString(string: "عبد الله", attributes: multipleAttributes)

    myMutableString.appendAttributedString(myAttrString)

    //some-text

    let someText = NSAttributedString(string: " finds ", attributes: nil)

    myMutableString.appendAttributedString(someText)

    //left-to-right
    let multipleAttributes2: [String : AnyObject] = [
        NSForegroundColorAttributeName: UIColor.blueColor(),
        NSBackgroundColorAttributeName: UIColor.yellowColor(),
        NSUnderlineStyleAttributeName: NSUnderlineStyle.StyleDouble.rawValue,
        NSWritingDirectionAttributeName : [NSWritingDirection.LeftToRight.rawValue | NSTextWritingDirection.Embedding.rawValue]
    ]

    let myAttrString2 = NSAttributedString(string: "restaurant", attributes: multipleAttributes2)

    myMutableString.appendAttributedString(myAttrString2)

    label.attributedText = myMutableString

    self.view.addSubview(label)
    label.sizeToFit()
    label.center = self.view.center

}

这是客户端代码......

public class DSprojectClient {
    public static void main(String[] args) {
        Client client = Client.create();
        Gson gson = new Gson();
        String method = "N2";
        WebResource webResource = client.resource("http://localhost:8080/EmployeeManage/demo/DS/" + method);
        EmployeeAddRequest addRequest = new EmployeeAddRequest();
        addRequest.setId(1103);

        String json = gson.toJson(addRequest/* , EmployeeAddRequest.class */);
        System.out.println(json);

        // String id = "1103";
        // String input = "{\"id\":\"1103\"}";
        ClientResponse response = webResource.type("application/json").post(ClientResponse.class, json);
        System.out.println("response" + response);
        System.out.println("Output from Server .... \n");
        String output = response.toString();
        System.out.println("output\n" + output);
        EmployeeResponse addResponse = new EmployeeResponse();
        addResponse = gson.fromJson(output, EmployeeResponse.class);
        System.out.println(output);

        System.out.println(addResponse.getId() + ****************************");

        System.out.println(output);
    }
}

这是json代码

@Path("/DS")
public class Standardization {

    @POST
    @Produces(MediaType.APPLICATION_JSON)
    @Consumes(MediaType.APPLICATION_JSON)
    @Path("/N2")
    public EmployeeResponse getDetails1(EmployeeRequest employeeRequest) throws Exception{
        DsUserService dsUserService = new DsUserService();
        System.out.println("getDetails1::object created");

        EmployeeResponse retval = dsUserService.AddEmp(employeeRequest.getId());
        return retval;
    }
}

点击db ...

输出

public class DsUserService {
    Gson gson = new Gson();
    PreparedStatement stmt = null;
    static Connection conn = null;

    static {
        try {
            Class.forName("com.mysql.jdbc.Driver");
            DB_Connector.getInstance();
            System.out.println(" Connection made :: "+DB_Connector.connection);
            conn = DB_Connector.connection; // Get DB Connection
        } catch (ClassNotFoundException e) {
            e.printStackTrace();
        }       
    }

    public  EmployeeResponse  AddEmp(int id) throws Exception{
        EmployeeResponse retval = new EmployeeResponse();
        if ( conn != null ) {
            System.out.println(" DB Connection Successful ");

            String query = "Select name FROM harish_table_employee WHERE id="+id;

            stmt = conn.prepareStatement(query);
            ResultSet rs = stmt.executeQuery();
            if (rs.next()){
                retval.setName(rs.getString("name"));
                retval.setId(rs.getInt("id"));
            }
        }

        return retval;
    }
}

请帮帮我..出了什么问题？

似乎您需要直接处理对象，而不需要在JSON中进行转换。您可以更改post参数：

ClientResponse response = webResource.type("application/json")
                                     .post(ClientResponse.class, json);

直接发送对象，而不是json，如下：

ClientResponse response = webResource.type("application/json")
                                     .post(ClientResponse.class, addRequest);

或者，在服务器端，您可以添加一个将String作为输入参数的服务：

@POST
@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.APPLICATION_JSON)
@Path("/N2")
public EmployeeResponse getDetails2(String employeeRequestJson) throws Exception{
    DsUserService dsUserService = new DsUserService();
    System.out.println("getDetails1::object created");

    EmployeeRequest employeeRequest = gson.fromJson(employeeRequestJson, EmployeeRequest.class);

    EmployeeResponse retval = dsUserService.AddEmp(employeeRequest.getId());
    return retval;
}

我正在研究json并且错误返回400 Bad Request的响应状态
