如何从Restful Web服务返回数组? [英] How to return an array from a Restful Web service?

问题描述

我有以下要返回的Web服务和数组值

I have the following web service in which I want to return and values of array

@GET
@Consumes("text/plain")
@Produces("text/plain")
public String[] getText(@PathParam("name") String Uname) {
    //TODO return proper representation object
    System.out.println("In Method " + Uname);
    String arr[]=null;
     arr=new String[2];
    arr[0]="demo";
    arr[1]="demo2";
    return arr;
}

但是当我测试此Web服务时，它给了我这个错误:GET RequestFailed RequestFailed --> Status: (406) Response: {

But when I test this web services it is giving me this error: GET RequestFailed RequestFailed --> Status: (406) Response: {

如果我想从REST Web服务返回数组怎么办?

So what should I do if I want to return an array from a REST webservice?

推荐答案

HTTP响应不支持纯文本响应中的数组.您要么需要手动将数组表示为String，然后将返回类型更改为String并返回，如下所示:

HTTP responses do not support Arrays in plain text responses. You either need to manually represent your array as a String, change the return type to String and return like this:

return Arrays.toString(arr);

或者您可以将数组转换为列表: return Arrays.asList(arr);

Or you could convert your array to a List: return Arrays.asList(arr);

，并在此处使用将其返回为JSON或XML的方法: 泽西岛:返回字符串列表

and use the approach to return it as JSON or XML here: Jersey: Return a list of strings
