Java 使用SpringBoot中的Validate.properties文件验证表单

我试图在Spring Boot中验证表单，当我单击submit按钮时，jsp将向我显示如何填充字段（或不填充字段）的消息。我创建了validation.properties，其中包含消息，但我总是收到错误

“在区域设置“en_US”的代码下找不到消息”

有人知道我如何在jsp中显示这些消息吗？我的validation.properties文件位于

src/main/resources/static

文件夹中，我在jsp文件中放置了validation.properties文件的链接

。 在验证类中，我有：

public void validate(Object target, Errors errors) {
    UserRegistration userRegistrated = (UserRegistration) target;

    ValidationUtils.rejectIfEmptyOrWhitespace(errors, "ime", "NotEmpty");
    ValidationUtils.rejectIfEmptyOrWhitespace(errors, "prezime", "NotEmpty");
    ValidationUtils.rejectIfEmptyOrWhitespace(errors, "email", "NotEmpty");

    if (service.findUsers(userRegistrated.getEmail())) {
        errors.rejectValue("email", "ExistUser");
    }

    ValidationUtils.rejectIfEmptyOrWhitespace(errors, "password", "NotEmpty");
    if (userRegistrated.getPassword().length() < 4) {
        errors.rejectValue("password", "LengthPass");
    }

    ValidationUtils.rejectIfEmptyOrWhitespace(errors, "repeatPassword", "NotEmpty");
    if (!userRegistrated.getRepeatPassword().equals(userRegistrated.getPassword())) {
        errors.rejectValue("repeatPassword", "MatchPass");
    }
}

我的jsp表单如下所示：

<form:form id="register" action="${action}" method="post" modelAttribute="userRegistration">
    <table>
        <tr>
            <td><form:label path="ime">Ime:</form:label></td>
            <td><form:input path="ime" type="text" placeholder="Ime" /></td>
            <td><form:errors path="ime" /></td>
        </tr>
        <tr>
            <td><form:label path="prezime">Prezime:</form:label></td>
            <td><form:input path="prezime" type="text" placeholder="Prezime"/></td>
            <td><form:errors path="prezime" /></td>
        </tr>
        <tr>
            <td><form:label path="email">Korisnicko ime(e-mail):</form:label></td>
            <td><form:input path="email" type="text" placeholder="Email" /></td>
            <td><form:errors path="email" /></td>
        </tr>
        <tr>
            <td><form:label path="password">Lozinka:</form:label></td>
            <td><form:input path="password" type="password" placeholder="Lozinka"/></td>
            <td><form:errors path="password" /></td>
        </tr>
        <tr>
            <td><form:label path="repeatPassword">Potvrda lozinke:</form:label></td>
            <td><form:input path="repeatPassword" type="password" placeholder="Potvrda lozinke"/></td>
            <td><form:errors path="repeatPassword" /></td>
        </tr>
        <tr><td colspan="3"><button type="submit">Submit</button></td></tr>
    </table>
</form:form>

我尝试将validation.properties放入

src/main/java

和

src/main/resources

文件夹中，但得到了相同的结果。我认为问题在于如何访问validation.properties文件，但是我不知道怎么做？我需要为它写一些配置吗？我在互联网上搜索了一下，大部分都是关于spring（不是spring boot）的解释，我不知道是否是一样的..提前谢谢

解决了它，我只是在application.properties中添加了

spring.messages.basename=validation

，并将validation.properties移动到src/main/resources。解决了它，我只是在application.properties中添加了
