Spring MessageSource not being used during validation
提问by Jeremy
I can't get my messages in messages.properties to be used during Spring validation of my form backing objects.
在我的表单支持对象的 Spring 验证期间，我无法在 messages.properties 中获取我的消息。
app-config.xml:
应用程序配置文件：
<bean id="messageSource" class="org.springframework.context.support.ResourceBundleMessageSource">
<property name="basename" value="messages" />
</bean>
WEB-INF/classes/messages.properties:
WEB-INF/classes/messages.properties：
NotEmpty=This field should not be empty.
Form Backing Object:
表单支持对象：
...
@NotEmpty
@Size(min=6, max=25)
private String password;
...
When I loop through all errors in the BindingResult and output the ObjectError's toString I get this:
当我遍历 BindingResult 中的所有错误并输出 ObjectError 的 toString 时，我得到了这个：
Field error in object 'settingsForm' on field 'password': rejected value []; codes [NotEmpty.settingsForm.password,NotEmpty.password,NotEmpty.java.lang.String,NotEmpty]; arguments [org.springframework.context.support.DefaultMessageSourceResolvable: codes [settingsForm.password,password]; arguments []; default message [password]]; default message [may not be empty]
As you can see the default message is "may not be empty" instead of my message "This field should not be empty".
如您所见，默认消息是“可能不为空”，而不是我的消息“此字段不应为空”。
I do get my correct message if I inject the messageSource into a controller and output this: messageSource.getMessage("NotEmpty", new Object [] {"password"}, "default empty message", null);
如果我将 messageSource 注入控制器并输出，我确实得到了正确的消息： messageSource.getMessage("NotEmpty", new Object [] {"password"}, "default empty message", null);
So why isn't the validation using my messages.properties? I'm running Spring 3.1.1. Thanks!
那么为什么不使用我的messages.properties 进行验证？我正在运行 Spring 3.1.1。谢谢！

@NotEmpty has a message property you can set on it. Since you're not setting it, it uses the default message.
@NotEmpty 有一个你可以设置的消息属性。由于您没有设置它，它使用默认消息。
@NotEmpty(message="{NotEmpty}")
should give you what you are looking for.
应该给你你正在寻找的东西。

By default HibernateValidator will get all of its messages from /WEB-INF/classes/ValidationMessages.propertiesIt reads this file directly itself, not through the Spring MessageSource.
默认情况下，HibernateValidator 将从/WEB-INF/classes/ValidationMessages.properties它自己直接读取这个文件中获取它的所有消息，而不是通过 Spring MessageSource。
If you want translations from a Spring Message source, set one on the LocalValidatorFactoryBean. This does require you to manually set up a validation bean inside your dispatcher servlet, rather than rely on mvc:annotation-driven.
如果您想从 Spring Message 源进行翻译，请在LocalValidatorFactoryBean上设置一个。这确实需要您在调度程序 servlet 中手动设置验证 bean，而不是依赖 mvc:annotation-driven。

When you want to set the custom message for any field using JSR 303 validations then you need to specify the bean name(LoginForm) and field name(password) in key of the message in property file. The format is CONSTRAINT_NAME.COMMAND_NAME.FIELD_NAME
当您想使用 JSR 303 验证为任何字段设置自定义消息时，您需要在属性文件的消息键中指定 bean 名称（LoginForm）和字段名称（密码）。格式为 CONSTRAINT_NAME.COMMAND_NAME.FIELD_NAME
NotEmpty.loginform.password=This field should not be empty.
