将数组或列表传递给@Path变量 - Spring / Java [英] Passing an Array or List to @Pathvariable - Spring/Java

问题描述

我在JBoss / Spring中做了一个简单的'get'。我希望客户端在url中传递一个整数数组。如何在服务器上进行设置？并显示客户端应该发送消息？

I am doing a simple 'get' in JBoss/Spring. I want the client to pass me an array of integers in the url. How do I set that up on the server? And show should the client send the message?

这就是我现在所拥有的。

This is what I have right now.

@RequestMapping(value="/test/{firstNameIds}", method=RequestMethod.GET)
@ResponseBody
public String test(@PathVariable List<Integer> firstNameIds)
{
     //What do I do??
     return "Dummy"; 
}

在客户端我希望传递类似

On the client I would like to pass something like

http://localhost:8080/public/test/[1,3,4,50]

当我这样做时，我收到一个错误：

When I did that I get an error:

java.lang.IllegalStateException：找不到@ @RequestMapping中的PathVariable [firstNameIds]

java.lang.IllegalStateException: Could not find @PathVariable [firstNameIds] in @RequestMapping

推荐答案

GET http://localhost:8080/public/test/1,2,3,4

@RequestMapping(value="/test/{firstNameIds}", method=RequestMethod.GET)
@ResponseBody
public String test(@PathVariable String[] firstNameIds)
{
    // firstNameIds: [1,2,3,4]
    return "Dummy"; 
}

（使用Spring MVC 4.0.1测试）
