hibernate 验证器 + jsf 2.0：UTF-8 格式的 ValidationMessages.properties

我在以 UTF-8 格式显示 Hibernate Validator 的自定义 ValidationMessages 时遇到问题。

对于常见的 jsf 消息，我遵循了以下建议：JSF 2.0 应用程序中具有 UTF-8 编码属性文件的 i18n https://stackoverflow.com/questions/3645491/i18n-with-utf-8-encoded-properties-files-in-jsf-2-0-appliaction- 我创建了 Text 类并在 faces-config.xml 中使用它。这是正常工作的。

但这种方法不适用于 ValidationMessages； UTF-8 中不显示特殊字符。

有人可以给我一些建议吗？非常感谢

我已经用同样的方法解决了。 Hibernate 验证器的配置文件位于 META-INF/validation.xml 中

示例验证.xml

<validation-config xmlns="http://jboss.org/xml/ns/javax/validation/configuration"
                   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
                   xsi:schemaLocation="http://jboss.org/xml/ns/javax/validation/configuration">
    <message-interpolator>com.mycompany.validation.utf8.UTF8ResourceBundleMessageInterpolator</message-interpolator>
</validation-config>

实施UTF 8 ResourceBundle 消息插值器

public class UTF8ResourceBundleMessageInterpolator extends ResourceBundleMessageInterpolator {

    public UTF8ResourceBundleMessageInterpolator() {
        super(new UTF8ResourceBundleLocator(ResourceBundleMessageInterpolator.USER_VALIDATION_MESSAGES));
    }
}

实施UTF8资源包定位器（PlatformResourceBundleLocator 类的克隆，并进行了小修复）

public class UTF8ResourceBundleLocator implements ResourceBundleLocator {
    private static final Logger logger = LoggerFactory.getLogger(UTF8ResourceBundleLocator.class);

    protected static final ResourceBundle.Control UTF8_CONTROL = new UTF8Control();

    private final String bundleName;

    public UTF8ResourceBundleLocator(String bundleName) {
        this.bundleName = bundleName;
    }


    /**
     * Search current thread classloader for the resource bundle. If not found,
     * search validator (this) classloader.
     *
     * @param locale The locale of the bundle to load.
     * @return the resource bundle or <code>null</code> if none is found.
     */
    @Override
    public ResourceBundle getResourceBundle(Locale locale) {
        ResourceBundle rb = null;
        ClassLoader classLoader = GetClassLoader.fromContext();
        if (classLoader != null) {
            rb = loadBundle(
                    classLoader, locale, bundleName
                            + " not found by thread local classloader"
            );
        }
        if (rb == null) {
            classLoader = GetClassLoader.fromClass(PlatformResourceBundleLocator.class);
            rb = loadBundle(
                    classLoader, locale, bundleName
                            + " not found by validator classloader"
            );
        }

        return rb;
    }

    private ResourceBundle loadBundle(ClassLoader classLoader, Locale locale, String message) {
        ResourceBundle rb = null;
        try {
            rb = ResourceBundle.getBundle(
                    bundleName, locale,
                    classLoader, UTF8_CONTROL
            );
        } catch (MissingResourceException ignored) {
            logger.trace(message);
        }
        return rb;
    }

    private static class GetClassLoader implements PrivilegedAction<ClassLoader> {
        private final Class<?> clazz;

        private static ClassLoader fromContext() {
            final GetClassLoader action = new GetClassLoader(null);
            if (System.getSecurityManager() != null) {
                return AccessController.doPrivileged(action);
            } else {
                return action.run();
            }
        }

        private static ClassLoader fromClass(Class<?> clazz) {
            if (clazz == null) {
                throw new IllegalArgumentException("Class is null");
            }
            final GetClassLoader action = new GetClassLoader(clazz);
            if (System.getSecurityManager() != null) {
                return AccessController.doPrivileged(action);
            } else {
                return action.run();
            }
        }

        private GetClassLoader(Class<?> clazz) {
            this.clazz = clazz;
        }

        @Override
        public ClassLoader run() {
            if (clazz != null) {
                return clazz.getClassLoader();
            } else {
                return Thread.currentThread().getContextClassLoader();
            }
        }
    }
}
