设有一个业务查询页面，查询的数据是一个组织或企业的部门组成信息表Department(对应的是Department类)，含有以下信息：部门id、部门编号、部门名称、部门负责人、部门编制(人数)、部门职责等信息，查询页面需要服务器提供JSON格式的数据

好的，以下是对应的Java代码：

public class Department {
    private int id;
    private String number;
    private String name;
    private String leader;
    private int personnel;
    private String duty;

    public Department(int id, String number, String name, String leader, int personnel, String duty) {
        this.id = id;
        this.number = number;
        this.name = name;
        this.leader = leader;
        this.personnel = personnel;
        this.duty = duty;
    }

    // getter and setter methods
}

// 在ServletDepartment类中处理请求
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    // 查询Department信息并封装为List<Department>
    List<Department> departmentList = queryDepartmentInfo();

    // 将List<Department>转为JSON格式数据
    JSONArray jsonArray = new JSONArray();
    for (Department department : departmentList) {
        JSONObject json = new JSONObject();
        json.put("id", department.getId());
        json.put("number", department.getNumber());
        json.put("name", department.getName());
        json.put("leader", department.getLeader());
        json.put("personnel", department.getPersonnel());
        json.put("duty", department.getDuty());
        jsonArray.add(json);
    }
    String json = jsonArray.toJSONString();

    // 设置响应头
    response.setContentType("application/json;charset=UTF-8");
    // 返回JSON格式数据
    PrintWriter out = response.getWriter();
    out.write(json);
    out.flush();
    out.close();
}

您可以使用浏览器或Postman等工具模拟请求并测试返回结果。希望对您有所帮助。
