休眠验证。消息显示为它们的标识符答案

【问题标题】：Hibernate Validation. Messages displayed as identifiers of them休眠验证。消息显示为它们的标识符
【发布时间】：2017-04-10 11:54:09
【问题描述】：

我正在为 Hibernate 验证和自定义错误消息而苦苦挣扎。就我而言，我对注册表单和消息包进行了简单的验证。我正在尝试使用这些消息，但每当出现错误时，它们就会在页面上显示为 {error.identifier}。我调试了代码，发现这条消息已经传递给了 Errors 对象下面的描述。请帮忙。我到处找。

以上消息仅由 Thymeleaf <p th:text="#{password.constraint}"></p> 撰写 MvcConfig.java：

@Bean
public LocaleResolver localeResolver() {
    return new CookieLocaleResolver();
}



@Bean
public LocaleChangeInterceptor localeChangeInterceptor() {
    LocaleChangeInterceptor lci = new LocaleChangeInterceptor();
    lci.setParamName("lang");
    return lci;
}


@Override
public void addInterceptors(InterceptorRegistry registry) {
    registry.addInterceptor(localeChangeInterceptor());
}
@Bean(name = "messageSource")
public MessageSource messageSource() {
    ReloadableResourceBundleMessageSource messageSource = new 
    ReloadableResourceBundleMessageSource();
    messageSource.setBasename("/i18n/messages");
    messageSource.setDefaultEncoding("UTF-8");
    messageSource.setFallbackToSystemLocale(false);
    messageSource.setCacheSeconds(0);
    return messageSource;
}

@Bean
public ValidatorFactory validator() {
    LocalValidatorFactoryBean factory = new LocalValidatorFactoryBean();
    factory.setValidationMessageSource(messageSource());
    return factory;
}

SignupForm.java：

import org.hibernate.validator.constraints.*;
import org.z1key.projects.entity.Role;
import org.z1key.projects.entity.User;

import javax.validation.constraints.Pattern;

@FieldMatch(first = "password", second = "verifyPassword", message = 
"Passwords are different.")
public class SignupForm {

private static final String NOT_BLANK_MESSAGE = "{notBlank.message}";
private static final String EMAIL_MESSAGE = "{email.constraint}";
private static final String PASSWORD_MESSAGE = "{password.constraint}";

@NotBlank
@Length(min = 5, max = 25)
@Pattern(regexp = "^[A-Za-z\\d]+$", message = "{login.constraint}")
private String login;

@NotBlank(message = NOT_BLANK_MESSAGE)
@Email(message = EMAIL_MESSAGE)
private String email;

@NotBlank(message = SignupForm.NOT_BLANK_MESSAGE)
@Length(min = 6, max = 40)
@Pattern(regexp = "^(?=.*[A-Za-z])(?=.*\\d)[A-Za-z\\d]+$", message = PASSWORD_MESSAGE)
private String password;

private String verifyPassword;

我还将 ValidationMessages.properties 添加到具有相同内容的资源文件夹中，并且消息被捕获并显示在页面上。但是询问如何在本地化的 messageSource 包中调用它。因为 @Bean validator() 不会产生任何影响。也许需要在某个地方注入这个 bean？

标签： java hibernate validation spring-boot

【解决方案1】：

我是新手，在混合不同来源的解决方案时犯了错误。解决方案非常简单和愚蠢。需要@Override 方法getValidator() 的扩展超类WebMvcConfigurerAdapter 而不是在那里定义@Bean validator()：

@Configuration
public class MvcConfig extends WebMvcConfigurerAdapter {
...
@Override
public Validator getValidator() {
    LocalValidatorFactoryBean factory = new LocalValidatorFactoryBean();
    factory.setValidationMessageSource(messageSource());
    return factory;
}
...

我不会删除问题。也许它会对其他人有所帮助。
