嗨，我坚持了几个星期，我找了很多，但没有找到答案，所以请帮助我，如果你可以：
这是我的客户类：
public class Customer {
private String firstName;
@Valid
@NotNull(message="")
private String lastName;
@Min(value=0 , message="bigger than zero")
@Max(value=10 , message="less than ten")
private int freePasses;
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
public int getFreePasses() {
return freePasses;
}
public void setFreePasses(int freePasses) {
this.freePasses = freePasses;
}这是我的控制器：
public class CustomerController {
@RequestMapping("/showForm")
public String showForm(Model model) {
Customer thecustomer=new Customer();
model.addAttribute("customer",thecustomer);
//first one is name and the second one is value
return "customer-form";
}
@RequestMapping("/processForm")
public String processForm(@Valid @ModelAttribute("customer") Customer thecustomer,BindingResult theresult,Errors error)
{
System.out.println(thecustomer.getLastName());
if(theresult.hasErrors()) {
System.out.println("!!!");
return "customer-form";}
else {
return "customer-confirmation";}
}此条件if（theresult.haserrors（））在max、min和notnull未验证的条件下总是返回true:（为什么？？？
这是我的html前端，以备您检查：
<%@taglib prefix="form" uri="http://www.springframework.org/tags/form" %>
<!DOCTYPE html>
<html>
<head>
<title>customer registration</title>
<style >
.error{color:red}
</style>
</head>
<body>
<form:form action="processForm" modelAttribute="customer">
<p>firstname:</p> <form:input path="firstName"/>
<br>
<p>lastname:</p> <form:input path="lastName" />
<form:errors path="lastName" cssClass="error"/>
<br>
<form:input path="freePasses" />
<form:errors path="freePasses" cssClass="error"/>
<input type="submit" value="Submit">
</form:form>
</body>
</html>
