Struts验证不起作用[奇怪]

标签： struts2 struts struts-validation

我认为我在struts验证中遇到了一个奇怪的情况，因为有时它会起作用，有时候不起作用。我用maven。在第一次安装时，我得到它的工作。但是在maven清理之后，它再也不会工作了。

  • 当我安装项目（maven install）时，xml验证（CustomerAction-validation.xml）不会复制到目标文件夹中的操作类包。我不知道为什么。
  • 如果我在“客户表单”操作中删除<interceptor-ref name="prepare"/>，则会出错。虽然我使用default-interceptor。没有定制。
  • 有关登录表单的其他问题（与验证无关）。如何将表单发布到另一个名称空间。我尝试使用namespace="/web"，但它不起作用。这就是为什么我尝试使用s:url，但它让我无法使用s:form

这是我的项目结构

答案 0 :(得分：0)

在Maven项目中，要部署在类路径上的非Java工件需要位于：

src/main/resources

因为您已将它们放在Java源目录树中，所以不会部署它们。

在您的具体案例中：

src/main/resources/struts/test/validation/action/CustomerValidation-validation.xml

这与部署到类路径的资源目录中的其他 XML文件的模式相同。

刚遇到我的验证文件未复制的问题。要解决此问题，您需要添加maven-war-plugin并正确配置它以包含XML文件。以下是我添加到我的pom.xml文件中以使其在我的项目中工作的内容：

        </plugin>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-war-plugin</artifactId>
            <version>2.4</version>
            <configuration>
                <webResources>
                    <resource>
                        <!-- this is relative to the pom.xml directory -->
                        <directory>src/main/java/com/project/controller/</directory>
                        <targetPath>WEB-INF/classes/com/project/controller/</targetPath>
                        <includes>
                            <include>**/*.xml</include>
                        </includes>
                    </resource>
                </webResources>
            </configuration>
        </plugin>
    </plugins>
</build>

您可以详细了解maven-war-plugin的工作原理here。
