Spring portlet mvc:@Valid 似乎不起作用
我创建了一个 bean 类并在我的控制器中使用它,但它似乎不起作用。 也就是说,即使我输入了无效的年龄,result.hasErrors
仍然是 false。
Bean 类:
public class User{
@Min(13)
private int age;
private String name;
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public String getName(){
return name;
}
public void setName(String name){
this.name = name;
}
}
控制器片段:
@ActionMapping(params = "myAction=validateUser")
public void validateUser(ActionRequest request, ActionResponse response, ModelMap model, @ModelAttribute("user") @Valid User user, BindingResult result ){
if(result.hasErrors()){
for(ObjectError oe : result.getAllErrors()){
System.out.println(oe.getDefaultMessage());
}
} else{
//code
}
}
JSP:
<form:form action="${registerUser}" method="post" commandName="user">
<b>User</b>
<form:input path="age"/>
<form:input path="name"/>
<input type="submit" value="register"/>
</form:form>
编辑: 我的 userRegistration-portlet.xml:

mvc:spring-validation 行给了我: cvc-complex-type.2.4.c 匹配的通配符是严格的,但找不到元素 mvc 的声明:注释驱动。
错误。
I created a bean class and use it in my controller but it does not seem to work.
Namely even though I enter an invalid age, result.hasErrors
is still false.
Bean class:
public class User{
@Min(13)
private int age;
private String name;
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public String getName(){
return name;
}
public void setName(String name){
this.name = name;
}
}
Controller snippet:
@ActionMapping(params = "myAction=validateUser")
public void validateUser(ActionRequest request, ActionResponse response, ModelMap model, @ModelAttribute("user") @Valid User user, BindingResult result ){
if(result.hasErrors()){
for(ObjectError oe : result.getAllErrors()){
System.out.println(oe.getDefaultMessage());
}
} else{
//code
}
}
JSP:
<form:form action="${registerUser}" method="post" commandName="user">
<b>User</b>
<form:input path="age"/>
<form:input path="name"/>
<input type="submit" value="register"/>
</form:form>

It's the mvc:spring-validation line that is giving me the: cvc-complex-type.2.4.c the matching wildcard is strict, but no declaration can be found for the element mvc:annotation-driven.
error.

我有完全相同的问题。我阅读了 https://jira.springframework.org/browse/SPR-6817 并工作通过添加到我的配置来解决问题:
您的项目中还需要有一个 JSR-303 验证器才能使其可用 为此,我使用了 Hibernate 验证器:http://www.hibernate.org/subprojects/validator.html
I had exactly the same problem. I read https://jira.springframework.org/browse/SPR-6817 and worked the problem around by adding to my config:
You also need to have a JSR-303 validator in your project in order for it to be available For this I used Hibernate Validator: http://www.hibernate.org/subprojects/validator.html
您需要
来启用 jsr-303 验证。如果您出于某种原因不想使用它,或者在某些时候它开始产生问题(就像对我一样),请查看 这个问题更新:
在
schemaLocation
中,mvc 条目应包含以下两个:You need
<mvc:annotation-driven />
to enable jsr-303 validation. If you don't want to use it for some reason, or if at some point it starts creating problems (like it did for me), take a look at this questionUpdate:
in
schemaLocation
the mvc entry should contain these two:您需要执行以下操作,这就是我在 spring portlet mvc 项目中解决的方法。
将
mvc:annotation-driven
添加到您的 applicatonContext.xml添加以下代码在你的控制器中:
<代码>@Autowired
私有 LocalValidatorFactoryBean 验证器;
<代码>@InitBinder
公共无效initBinder(WebDataBinder活页夹){
binder.setValidator(验证器);
}
You need to do the following, that is how I solved in the spring portlet mvc project.
Add
mvc:annotation-driven
to your applicatonContext.xmlAdd the following code in your controller:
@Autowired
private LocalValidatorFactoryBean validator;
@InitBinder
public void initBinder(WebDataBinder binder) {
binder.setValidator(validator);
}
我认为原因是
ServletRequestDataBinder
(扩展 DataBinder)没有org.springframework.validation.Validator
实例,因此它不会验证任何内容(验证 @Valid 注解的 bean必须有 javax.validation.Validator 实例)。org.springframework.validation.DataBinder
您可以在
@InitBinder
注解的方法中设置 Validator 实例:-您还可以在 WebBindingInitializer。
StandardBindingInitializer
要创建 LocalValidatorFactoryBean 的实例,请使用 mvc:annotation-driven 或 将 LocalValidatorFactoryBean 设置为 bean。
I think the reason is that
ServletRequestDataBinder
(extends DataBinder) has noorg.springframework.validation.Validator
instance, so it does not validate anything (to validate @Valid annotated bean you must have javax.validation.Validator instance).org.springframework.validation.DataBinder
You can set the Validator instance in
@InitBinder
annotated methods:-Yo can also set the validator instance in WebBindingInitializer.
StandardBindingInitializer
To create an instance of LocalValidatorFactoryBean either use mvc:annotation-driven OR set up LocalValidatorFactoryBean as bean.
使用 hibernate-validator jar 6.2 及以下版本,因此它可以支持 spring 5 及以上版本...
在 pom.xml 中添加依赖项:
Use hibernate-validator jar 6.2 version and below and so it can support spring 5 and above versions...
Add dependency in pom.xml:
