问题背景： 
我要在一个表单里同时一次性提交多名乘客的个人信息到SpringMVC，前端HTML和SpringMVC Controller里该如何处理？

  • 第1种方法：表单提交，以字段数组接收；
  • 第2种方法：表单提交，以BeanListModel接收；
  • 第3种方法：将Json对象序列化成Json字符串提交，以List接收；
  • 第4种方法：将表单对象序列化成Json字符串提交，以List接收； 
    第4种方法其实是第3种方法的升级，就是将表单转成Json对象，再转成Json字符串提交； 
    然而，第4种方法还不支持含有多选控件表单的提交，故应该还有第5种加强版的方法。

以上4种方法都共用同一个User实体类，代码如下：

<code class="hljs cs has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"><span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">public</span> <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">class</span> User {

    <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">private</span> Integer id;
    <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">private</span> String name;
    <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">private</span> String pwd;

    @Override
    <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">public</span> String <span class="hljs-title" style="box-sizing: border-box;">toString</span>() {
        <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">return</span> <span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"User{"</span> +
                <span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"id="</span> + id +
                <span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">", name='"</span> + name + <span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">'\''</span> +
                <span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">", pwd='"</span> + pwd + <span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">'\''</span> +
                <span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">'}'</span>;
    }
    <span class="hljs-comment" style="color: rgb(136, 0, 0); box-sizing: border-box;">// .......后面还有getter、setter方法，省略了</span>

总结： 
第1、2种方法其实都有一个共同的BUG：假如提交三条记录时，前面两条记录的某些字段不填值的话，在SpringMVC里接收不准确了。而且，每2种方法在HMTL中需要给name属性添加[下标]，如果下标有跨度的话（比如第一组控件下标是0,第二组下标是2），那么SpringMVC里其实的是0到2三个对象的，默认下标是1的那个对象全为null值。 
第3、4种方法最实用。

基于Simulink环境，提供一个关于如何对EMI抑制的DC-DC变换器进行仿真建模的示例

EMI定义：电磁干扰是指任何能中断、阻碍、降低或限制电气设备有效性能的电磁能量。重要性合规性：确保产品符合国际和地方的EMC标准。可靠性：减少因外部或内部EMI导致的系统故障风险。挑战滤波设计：合理设计输入输出滤波器以抑制传导EMI。布局与接地：良好的PCB设计对于减少辐射EMI至关重要。屏蔽：使用金属屏蔽来保护敏感电路不受外界干扰。首先明确要模拟的任务内容。设计一个能够在高频操作下有效抑制EMI的DC-DC变换器。根据工作频率和谐振元件值确定合适的滤波器参数。
