如何指定在Spring表单中默认选择哪个值:选择

@GetMapping("/form")
public ModelAndView showForm() {
    ModelAndView modelAndView = new ModelAndView("form");
    
    List<String> options = Arrays.asList("Option 1", "Option 2", "Option 3");
    modelAndView.addObject("options", options);
    
    return modelAndView;
}

<form action="/submit" method="post">
    <select name="option">
        <option th:each="option : ${options}" th:value="${option}" th:selected="${option == 'Option 2'}" th:text="${option}"></option>
    </select>
    <input type="submit" value="Submit">
</form>

@PostMapping("/submit")
public String submitForm(@RequestParam("option") String option) {
    // 处理用户选择的值
    return "result";
}
