與球衣

Question

休息POST請求我嘗試從捲曲調用REST Web服務，在linux下，還可以使用球衣
然後返回

A message body reader for Java type, class mypackage.UserGroupsData, and MIME media type, application/json, was not found 

Mappign類是

public class UserGroupsData { 
private int id; 
private String name;  
public int getId() { 
    return id; 
} public void setId(int id) { 
    this.id = id; 
}public String getName() { 
    return name; 
}public void setName(String name) { 
    this.name = name; 
} public int getId() { 
    return id; 
}} 

我的POST方法編號

@POST 
@Path("/getQualifiedNumbers") 
@Produces("application/json") 
@Consumes("application/json") 
public Response getQualifiedNumbers(UserGroupsData userGroup){    
    return Response.status(201).entity(userGroup).build();   
} 

我用來打電話的捲曲命令是

curl -v -H "Accept: application/json" -H "Content-type: application/json" -X POST -d '{"id":"1","name":"e"}' http://localhost:8080/url/getQualifiedNumbers 

服務器是碼頭

感謝

嘗試在你的類添加註釋 「@XmlRootElement」。它應該成爲這樣的：

import javax.xml.bind.annotation.XmlRootElement; 

@XmlRootElement 
public class UserGroupsData { 
private int id; 
private String name;  
public int getId() { 
    return id; 
} public void setId(int id) { 
    this.id = id; 
}public String getName() { 
    return name; 
}public void setName(String name) { 
    this.name = name; 
} public int getId() { 
    return id; 
}}
