如何从thymyleaf文本框中调用带有两个参数的构造函数?

Question

我有一个textfield

<input type="text" class="form-control" id="name" th:value="*{name}" th:field="*{name}"/>

和具有两个构造函数的实体客户

Costumer(String name)
Costumer(Locale locale, String name)

对于上面的文本框，只调用第一个构造函数!如何调用有两个参数的构造函数，以及如何将区域设置传递给它?

如果我是你，我会用form

TestForm:

public class TestForm {
    private String name;
    private String locale;
    public TestForm() {
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public String getLocale() {
        return locale;
    }
    public void setLocale(String locale) {
        this.locale = locale;
    }
    @Override
    public String toString() {
        return "TestForm [name=" + name + ", locale=" + locale + "]";
    }
}

控制器:

@RequestMapping(value = "/test", method = GET)
public String test(final ModelMap modelMap) {
    modelMap.put("testForm", new TestForm());
return "/test";
}
@RequestMapping(value = "/test", method = POST)
public String posttest(@ModelAttribute("testForm") final TestForm testForm) {
    System.out.println(testForm);
return "redirect:/somewhere/else";
}

test.html:

    <form th:object="${testForm}" method="post">
        <input type="text" class="form-control" id="name" th:value="*{name}" th:field="*{name}"/>
        <input type="text" class="form-control" id="locale" th:value="*{locale}" th:field="*{locale}"/>
        <button type="submit">Save</button>
    </form>
