首先,合同方式： –

Specify a custom Spring MessageSource for resolving validation
messages,instead of relying on
JSR-303’s default
“ValidationMessages.properties” bundle
in the classpath. This may refer to a
Spring context’s shared
“messageSource” bean,or to some
special MessageSource setup for
validation purposes only.

注意：此功能需要休眠
验证器4.1或更高版本
类路径.你可以使用a
不同的验证提供商,但
Hibernate验证器
ResourceBundleMessageInterpolator
课程必须在之前访问
组态.

指定此属性或
“messageInterpolator”,而不是两者.如果
你想建立一个习惯
MessageInterpolator,考虑派生
来自Hibernate Validator的
ResourceBundleMessageInterpolator和
穿过春天
MessageSourceResourceBundleLocator
构建插值器时.

您可以通过调用此方法来指定自定义的message.properties(或.xml)…像这样…

我-beans.xml文件

<bean name="validator"
    class="org.springframework.validation.beanvalidation.LocalValidatorfactorybean">
    <property name="validationMessageSource">
        <ref bean="resourceBundleLocator"/>
    </property>
</bean>

<bean name="resourceBundleLocator" class="org.springframework.context.support.ReloadableResourceBundleMessageSource">
    <property name="basenames">
        <list>
            <value>Meta-INF/validation_errors</value>
        </list>
    </property>
</bean>

validation_errors.properties

javax.validation.constraints.NotNull.message=MyNotNullMessage

Person.java

class Person {
    private String firstName;
    private String lastName;

    @NotNull
    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;
    }
}

BeanValidationTest.java

public class BeanValidationTest {

    private static ApplicationContext applicationContext; 

    @BeforeClass
    public static void initialize() {
        applicationContext = new ClassPathXmlApplicationContext("classpath:Meta-INF/spring/webmvc-beans.xml");
        Assert.assertNotNull(applicationContext);
    }

    @Test
    public void test() {
        LocalValidatorfactorybean factory = applicationContext.getBean("validator",LocalValidatorfactorybean.class);
        Validator validator = factory.getValidator();
        Person person = new Person();
        person.setLastName("dude");
        Set<ConstraintViolation<Person>> violations = validator.validate(person);
        for(ConstraintViolation<Person> violation : violations) {
            System.out.println("Custom Message:- " + violation.getMessage());
        }
    }

}

Outupt：自定义消息： – MyNotNullMessage
