如何将arraylist从servlet传递到javascript？

import com.fasterxml.jackson.databind.ObjectMapper;
import java.util.ArrayList;
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class MyServlet extends HttpServlet {
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        ArrayList<String> arrayList = new ArrayList<>();
        arrayList.add("Item 1");
        arrayList.add("Item 2");
        arrayList.add("Item 3");

        // 将ArrayList转换为JSON字符串
        ObjectMapper mapper = new ObjectMapper();
        String json = mapper.writeValueAsString(arrayList);

        // 设置响应的内容类型为application/json
        response.setContentType("application/json");
        response.setCharacterEncoding("UTF-8");

        // 将JSON字符串作为响应发送给前端
        response.getWriter().write(json);
    }
}

function getData() {
    var xhr = new XMLHttpRequest();
    xhr.onreadystatechange = function() {
        if (xhr.readyState === 4 && xhr.status === 200) {
            var response = JSON.parse(xhr.responseText);
            // 在控制台打印接收到的数据
            console.log(response);
        }
    };
    xhr.open("GET", "servlet-url", true);
    xhr.send();
}

// 调用函数获取数据
getData();
