Spring MVC验证列表并报告无效值

public class User {
    private String name;
    private int age;

    // 省略构造函数和getter/setter方法
}

@Controller
public class UserController {

    @PostMapping("/users")
    public String createUser(@Valid @ModelAttribute("user") User user, BindingResult result) {
        if (result.hasErrors()) {
            // 处理验证错误
        } else {
            // 验证通过，执行相应的逻辑
        }
    }
}

<form:form modelAttribute="user" method="POST" action="/users">
    <form:input path="name" />
    <form:errors path="name" />

    <form:input path="age" />
    <form:errors path="age" />

    <input type="submit" value="Submit" />
</form:form>

<bean id="validator" class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean" />
