如何将JSON数组转换为Java列表。我正在使用svenson

您不能将此json转换为，

List

Map

String

..."Example": [        { "foo": "a1", "bar": "b1", "fubar": "c1"        },        { "foo": "a2", "bar": "b2", "fubar": "c2"        },        ...]}

在此，“ Example”是键（字符串），值是Example的List对象。

试试这个：

 parser.addTypeHint("Example[]", Example.class); Map<String,List<Example>> result1 = parser.parse(Map.class, json); for (Entry<String, List<Example>> entry : result1.entrySet()) {     for (Example example : entry.getValue()) {          System.out.println("VALUE :->"+ example.getFoo());     } }

的完整代码

Example

import java.util.List;import java.util.Map;import java.util.Map.Entry;import org.svenson.JSONParser;public class Test {    public static void main(String[] args) {        JSonParser parser = new JSonParser();        parser.addTypeHint(".Example[]", Example.class);        String json = "{" + ""Example": [" + "{" + ""foo": "a1","     + ""bar": "b1"," + ""fubar": "c1"" + "}," + "{"     + ""foo": "a2"," + ""bar": "b2"," + ""fubar": "c2""     + "}," + "{" + ""foo": "a3"," + ""bar": "b3","     + ""fubar": "c3"" + "}" + "]" + "}"";        parser.addTypeHint("Example[]", Example.class);        Map<String, List<Example>> result1 = parser.parse(Map.class, json);        for (Entry<String, List<Example>> entry : result1.entrySet()) { for (Example example : entry.getValue()) {     System.out.println("VALUE :->" + example.getFoo()); }        }    }}public class Example {    private String foo;    private String bar;    private String fubar;    public Example(){}    public void setFoo(String foo) {        this.foo = foo;    }    public String getFoo() {        return foo;    }    public void setBar(String bar) {        this.bar = bar;    }    public String getBar() {        return bar;    }    public void setFubar(String fubar) {        this.fubar = fubar;    }    public String getFubar() {        return fubar;    }}

输出 ：

VALUE :->a1VALUE :->a2VALUE :->a3
