list转fastjson

要将List转为FastJSON，你可以按照以下步骤进行操作：
1. 首先，将List转换为JSONArray格式的字符串。你可以使用`JSONArray.toJSONString(list)`来实现这一步骤。
2. 接下来，将JSONArray格式的字符串转换为List。你可以使用`JSONArray.parseArray(jsonString, T.class)`来实现这一步骤。其中，`T`表示你希望转换后的List的泛型类型。
以下是一个示例代码，展示了如何将List转换为FastJSON：

import com.alibaba.fastjson.JSONArray;import java.util.ArrayList;
import java.util.List;
import java.util.Map;

public class Main {
    public static void main(String[] args) {
        List<Map<String, Object>> list = new ArrayList<>();//List泛型可自定义
        
        //构造测试数据
        Map<String, Object> map1 = new HashMap<>();
        Map<String, Object> map2 = new HashMap<>();
        Map<String, Object> map3 = new HashMap<>();
        map1.put("aaa","111");
        map2.put("bbb","222");
        map3.put("ccc","333");
        
        list.add(map1);
        list.add(map2);
        list.add(map3);
        
        //list 转 JSONArray
        String jsonString = JSONArray.toJSONString(list);
        System.out.println(jsonString);
        
        //JSONArray 转 list
        List<Map> lists = JSONArray.parseArray(jsonString, Map.class);
        
        //打印测试结果
        for (Map map:lists) {
            System.out.println("==========");
            System.out.println(map.get("aaa"));
            System.out.println(map.get("bbb"));
            System.out.println(map.get("ccc"));
        }
    }
}

以上代码将会输出以下结果：

<span class="em">1</span><span class="em">2</span><span class="em">3</span>
