如何在Jersey/Spring中使用@QueryParam重载方法?

问题描述

我想用@QueryParam重载一个方法，但是每次我尝试执行此代码时，它都会抛出:

I would like to overload a method with the @QueryParam but everytime I try to execute this code it throws:

SEVERE: Exception occurred when intialization
com.sun.jersey.spi.inject.Errors$ErrorMessagesException

我的代码是:

@GET
@Path("/test")
@Produces("text/plain")
public String getText(@QueryParam("PID") String pid)
{
  return pid;
}

@GET
@Path("/test")
@Produces("text/plain")
public String getText(@QueryParam("PID") String pid, @QueryParam("NAME") String name)
{
  return pid + name;
}

推荐答案

不能.

在Java中还可以，但从servlet的角度来看，jersey需要将每个url映射到类中的某个函数.

It's ok in java, but the thing about it is - from the servlet side - jersey needs to map each url to some function in your class.

您可以做的当然是将其分为2种方法，或者构建一种检查参数并执行正确逻辑的方法.

What you can do is, of course, separate it into 2 methods, or build one method that checks the parameters and does the right logic.
