Question

这是这个问题的后续问题：

我有一个包含这种方法的课程：

public static MyClass fromString(String json) 
{
   Gson gson = new Gson();
   MyClass user = gson.fromJson(json, MyClass.class);
   return user;
}

全班：

public class MyClass
{
    public String name;
    public PortalNameEnum  portalName;
    public PortalUserTypeEnum portalUserType;
    public String   notes;

public MyClass(String name, PortalNameEnum portalName,
        PortalUserTypeEnum portalUserType, String notes)
{
    super();
    this.portalName = portalName;
    this.portalUserType = portalUserType;
    this.name = name;
    this.notes = notes;
}

public static MyClass fromString(String json) 
{
   Gson gson = new Gson();
   PortalUserInfo user = gson.fromJson(json, PortalUserInfo.class);
   return user;
}

public PortalNameEnum getPortalName()
{
    return portalName;
}

public void setPortalName(PortalNameEnum portalName)
{
    this.portalName = portalName;
}

public PortalUserTypeEnum getPortalUserType()
{
    return portalUserType;
}

public void setPortalUserType(PortalUserTypeEnum portalUserType)
{
    this.portalUserType = portalUserType;
}

public String getName()
{
    return name;
}

public void setName(String name)
{
    this.name = name;
}

public String getNotes()
{
    return notes;
}

public void setNotes(String notes)
{
    this.notes = notes;
}

}

我有一个获得方法的资源：

@Path("/myclasscall")
@GET
@UnitOfWork
public String registerPortalUser(@Context HttpServletRequest req, @QueryParam("callback") String callback, @QueryParam("myclass") MyClass recordData) throws Throwable
{ .. }

似乎没有调用fromString方法，并且资源方法总是为null，即使我在控制台中看到请求本身，我确实看到了一个已经传递的字符串。那是为什么？

Answer 1

问题出在客户身上。他没有传递一个名为“myclass”的参数，而是分别传递了所有字段。将它们合并到一个Json实例后，它被修复了。

不调用Jersey对象的fromString方法
