list转jsonString字符

要将List转换为JSON字符串，可以使用Fastjson提供的工具类。首先，我们需要导入Fastjson库。然后，使用JSONArray类的toJSONString方法将List对象转换为JSON字符串。示例代码如下：

import com.alibaba.fastjson.JSONArray;

List<String> list = new ArrayList<>();
list.add("item1");
list.add("item2");
list.add("item3");

String jsonString = JSONArray.toJSONString(list);

这样，list就成功转换为了JSON字符串。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
