【问题描述】：
需要你的帮助！当我在特定 URL 生成 JSON 格式时。我从我的应用程序中获得了 JSON 格式的所有数据。例如，我不是只生成帖子信息，而是一次获得了 getMessageByID 和 getAllMessage ...
“网址：http://localhost:8080/Messenger/rest/messenger/messeger/i%20love%20running/Maks/Burkov/32059087”
为什么它会产生所有信息？ 这是我得到的：
我需要做什么才能只生成@Post 信息？
{
"name": "Maks",
"lastname": "Burkov",
"meessegaDate": 1461776715593,
"id_messenger": 32059087,
I need only the 4 lines above!
"message": "i love running",
"allmessages": [
"i love running"
]
}
@Path("/messeger")
public class MessageResource {
@POST
@Path("/{message}/{messager_name}/{messager_last_name}/{messager_id}")
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_JSON)
public MessengerDatabase ddMessage(@PathParam("message") String message, @PathParam("messager_name")String messager_name, @PathParam("messager_last_name")String messager_last_name ,@PathParam("messager_id") long messager_id){
MessengerDatabase mes = new MessageService().addMessage(message, messager_name, messager_last_name, messager_id);
return mes;
}
@GET
@Path("/{messager_id}")
@Produces(MediaType.APPLICATION_JSON)
public String GetMessageById(@PathParam("messager_id") long id){
String message = new MessageService().getMessageById(id);
System.out.println(message);
return message;
}
@GET
@Path("/allmess")
@Produces(MediaType.APPLICATION_JSON)
public List<String> getAllMessages(){
return new MessageService().getAllMessages();
}
}
信使数据库：
public class MessengerDatabase {
public MessengerDatabase() {}
public MessengerDatabase(String message, long id){
setMessageByid(message, id);
}
public MessengerDatabase(String message, String messager_name, String messager_lastname,long messager_id) {
Date date_generator = new Date();
setMeessegaDate(date_generator);
setId_messenger(messager_id);
setMessage(message);
setMessageByid(message,messager_id);
setLastname(messager_lastname);
setName(messager_name);
System.out.println("In Constuctor");
}
public String getName() {
return name;
}
private void setName(String name) {
this.name = name;
}
public String getLastname() {
return lastname;
}
private void setLastname(String lastname) {
this.lastname = lastname;
}
public Date getMeessegaDate() {
return meessegaDate;
}
private void setMeessegaDate(Date meessegaDate) {
this.meessegaDate = meessegaDate;
}
public long getId_messenger() {
return id_messenger;
}
private void setId_messenger(long id_messenger) {
this.id_messenger = id_messenger;
}
public String getMessage() {
return message;
}
private void setMessage(String message) {
this.message = message;
}
private void setMessageByid(String message, long id){
allmessages.add(message);
message_by_messenger_id.put(id,message);
}
@Override
public String toString() {
return "MessengerDatabase [name=" + name + ", lastname=" + lastname
+ ", meessegaDate=" + meessegaDate + ", id_messenger=" + id_messenger + ", message=" + message + "]";
}
public List<String> getAllmessages() {
return allmessages;
}
public String getMessage_by_messeger_id(long id) {
String messageById = message_by_messenger_id.get(id);
return messageById;
}
private static Map<Long,String> message_by_messenger_id = new HashMap<>();
private static List<String> allmessages = new ArrayList<>();
private String name;
private String lastname;
private Date meessegaDate;
private long id_messenger;
private String message;

MessengerDatabase 是如何定义的？您能指定您使用的网址吗？
