@Valid不能在Spring中工作java

我在Spring mvc中使用了@Valid。它似乎沒有做任何事情。這裏是我的PROGRAME@Valid不能在Spring中工作java

爲spring-servlet.xml

<?xml version="1.0" encoding="UTF-8"?> 

<beans xmlns="http://www.springframework.org/schema/beans" 
     xmlns:context="http://www.springframework.org/schema/context" 
     xmlns:mvc="http://www.springframework.org/schema/mvc" 
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
     xsi:schemaLocation=" 
    http://www.springframework.org/schema/beans 
    http://www.springframework.org/schema/beans/spring-beans-3.0.xsd 
    http://www.springframework.org/schema/context 
    http://www.springframework.org/schema/context/spring-context-3.0.xsd 
    http://www.springframework.org/schema/mvc 
    http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd"> 
     <mvc:annotation-driven/> 
     <context:component-scan base-package="com.mvc"></context:component-scan> 
     <bean id="viewResolver" 
       class="org.springframework.web.servlet.view.InternalResourceViewResolver"> 
       <property name="prefix"> 
         <value>/</value> 
       </property> 
       <property name="suffix"> 
         <value>.jsp</value> 
       </property> 
     </bean> 
</beans>

這裏是控制器

@RequestMapping(value="/test2") 

public ModelAndView hello2(@Valid @ModelAttribute("person1") Person person1, BindingResult result){ 

    if(result.hasErrors()){ 
     ModelAndView model=new ModelAndView("form2"); 
     return model; 
    } 

    ModelAndView model = new ModelAndView("test2"); 

    return model; 
}

Person.java 在這裏，我已經使用 @NotNull @Size(min=5,max=30,message = "last name should be 5-30 long")

public class Person { 
    private String firstName; 
    @NotNull 
    @Size(min=5,max=30,message = "last name should be 5-30 long") 
    private String lastName; 
    private int age; 

    public String getLastName() { 
     return lastName; 
    } 

    public void setLastName(String lastName) { 
     this.lastName = lastName; 
    } 

    public String getFirstName() { 
     return firstName; 
    } 

    public void setFirstName(String firstName) { 
     this.firstName = firstName; 
    } 

    public int getAge() { 
     return age; 
    } 

    public void setAge(int age) { 
     this.age = age; 
    } 

}

的pom.xml

你可以顯示與表單的jsp頁面？ –

你也應該把你的jsp頁面放在web-inf文件夾下。 –

改用hibernate validator 5.4.1最終版本。版本6用於bean驗證api 2.0 – mhshimul

查找一個Hibernate版本低於6，並再次嘗試它，使用@ModelAttribute是，你可以在表單的輸入映射到一個bean和6.0 api 2.0可能會導致一些關於Bean的問題。我建議你看看這個話題，以清楚更多的這個問題::: Spring annotations @ModelAttribute and @Valid
