spring-mvc - 在 Spring 3.1.1 中使用 javax.validation API

Question

我正在使用

Spring 3.3.1

WebLogic 11g

JDK 1.60_29

我决定要进行基于 Java 的表单验证。当我去编译我的代码时，我看到我需要 javax.validation 库。所以，我把这些标签放在我的 pom.xml 中:

<dependency>
    <groupId>javax.validation</groupId>
    <artifactId>validation-api</artifactId>
    <version>1.0.CR5</version>
</dependency>

我得到了一个额外的 jar :

validation-api-1.0.CR5.jar

我把它放到我的 war/WEB-INF/lib 中

我启动了 WebLogic 11g，Spring 吐血了:

谷歌搜索我一直看到 hibernate 提到的 javax.validation API。鉴于这一点和错误消息，我猜测我需要休眠来提供一些东西，所以我在我的 war/WEB-INF/lib 中添加了一个休眠 jar，但这导致了更多的错误。

关于如何让 Spring 3.1.1 和 javax.validation API 发挥良好的任何想法？

非常感谢提前

史蒂夫

Weblogic 11G 与 Java EE 5 兼容，因此不实现作为 Java EE 6 一部分添加的 JSR-303 javax.validation 规范。因此，您必须为此添加一个默认提供程序，例如 Hibernate Validator :

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-validator</artifactId>
    <version>4.3.0.Final</version>
</dependency>

或者，如果您升级到符合 Java EE 6 的应用程序服务器，则可以忽略此依赖项，因为它已包含在内。

顺便说一句，您可能需要考虑将您的 javax.validation 依赖更新到版本 1.0.0.GA 。
