我正在尝试创建一个返回用户详细信息的REST Web服务。
这是我的代码:
//Actual web service methods implemented from here
@GET
@Path("login/{email}/{password}")
@Produces("application/json")
public Tourist loginUser(@PathParam("email") String email, @PathParam("password") String password) {
List<Tourist> tourists = super.findAll();
for (Tourist tourist : tourists) {
if (tourist.getEmail().equals(email) && tourist.getPassword().equals(password)) {
return tourist;
}
}
//if we got here the login failed
return null;
}
这会生成以下JSON:
{
"email": "adrian.olar@email.ro",
"fname": "Adrian",
"lname": "Olar",
"touristId": 1
}
我需要的是:
{"tourist":{
"email": "adrian.olar@email.ro",
"fname": "Adrian",
"lname": "Olar",
"touristId": 1
}
}
我需要在代码中添加什么来产生这个?

如果确实希望将Tourist
包装到另一个对象中,则可以执行此操作。
Tourist.java
:
package entities;
import javax.xml.bind.annotation.XmlRootElement;
@XmlRootElement
public class Tourist {
int touristId;
String email;
String fname;
String lname;
TouristWrapper.java
:
package entities;
import javax.xml.bind.annotation.XmlRootElement;
@XmlRootElement
public class TouristWrapper {
Tourist tourist;
SOResource.java
:
package rest;
import entities.Tourist;
import entities.TouristWrapper;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;
@Path("/so")
public class SOResource {
@GET
@Path("/tourists/{id}")
@Produces("application/json")
public TouristWrapper loginUser(@PathParam("id") int id) {
Tourist tourist = new Tourist(id, "foo@example.com", "John", "Doe");
TouristWrapper touristWrapper = new TouristWrapper(tourist);
return touristWrapper;
}
}
我简化了您的用例,但您明白了这一点:不返回Tourist
,而是TouristWrapper
。返回的JSON是:
{
"tourist": {
"email": "foo@example.com",
"fname": "John",
"lname": "Doe",
"touristId": 1
}
}
