我们有几个包含50多个字段的表，必须使用RESTful服务（RESTeasy）作为参数传递，但我们要避免使用50行@QueryParam("field") Object field。有没有办法发送列表，地图或对象？
这是我们目前使用的代码：
@POST
@Path("/custships")
@Produces("application/json")
void postCustship(@QueryParam("custShipMap") HashMap<String, Object> custShipMap);
这是我们得到的例外：
java.lang.RuntimeException: Unable to find a constructor that takes a String param or a valueOf() or fromString() method for javax.ws.rs.QueryParam("custShipMap") on public abstract void com.waudware.pics.service.ICustshipService.postCustship(java.util.HashMap) for basetype: java.util.HashMap

答案 0 :(得分：1)
传递数据的正确方法是通过PUT并使用JSON或XML之类的东西来表示数据作为PUT的正文。然后使用@Consumes("application/json")，如果您映射一个或Map of Maps，它会将内容解组为一个对象。
如果您正在做有副作用的事情，您可以以相同的方式使用POST。
无论哪种方式传递查询参数都不是RESTful，它最多是RPC over HTTP，并且非常不鼓励。
