在我的应用程序验证过程中，我使用message.properties文件来显示自定义消息。但它不起作用，并在 App Engine 服务器日志中显示以下错误
org.springframework.web.servlet.tags.RequestContextAwareTag doStartTag：在区域设置“en_US”的代码“notmatch.password”下找不到消息。org.springframework.context.NoSuchMessageException：在区域设置“en_US”的代码“notmatch.password”下找不到消息。
我的验证代码是：
public void validate(Object target, Errors errors) {
ValidationUtils.rejectIfEmptyOrWhitespace(errors, "password",
"required.password", "Field name is required.");
ValidationUtils.rejectIfEmptyOrWhitespace(errors, "confirmPassword",
"required.confirmPassword", "Field name is required.");
NewUser cust = (NewUser) target;
if (!(cust.getPassword().equals(cust.getConfirmPassword()))) {
errors.rejectValue("password", "notmatch.password");
}
}
我的配置xml是：
