如何在 Spring Roo 中添加新页面并在单击按钮后调用操作？答案

【问题描述】：

我想知道如何在 Spring Roo 中添加新页面并在单击按钮后调用操作？

目前我可以在单击保存按钮后将用户添加到数据库。 Spring Roo 中的所有文件都是自动生成的。我刚刚按照 Spring Roo 的说明进行操作。我想继续开发应用程序并创建一个在单击保存按钮后生成的新页面。页面上基本会显示“新用户添加成功”等信息。我想我会首先检查用户是否在特定的表中，如果是我将返回 false，这意味着将用户添加到数据库不成功，否则我将显示“新用户已成功添加”。我从这里Adding a custom page in spring roo 遵循了规则，但它是关于向 Spring Roo 添加自定义页面，并且缺少如何首先创建该页面的那部分。当我遵循链接中的规则时，我收到此错误：

我曾经使用 Eclipse，而 Spring Roo 对我来说太新了。我尝试了教程，但是我正在做的事情没有得到很好的解释。我将不胜感激。如果你给我指路。谢谢你。如果您需要发布其他信息，请告诉我。

【解决方案1】：

我认为问题是因为 Spring 中的 messageSource 。所以你应该在你的项目中找到文件messages_en.properties 或messages.properties 或者像 *.properties 这样的文件。 .properties 文件的路径可以在 dispathcher-servlet.xml 中更改（因此请检查 src/main/java/resource ）

<context:property-placeholder location="classpath*:META-INF/spring/*.properties"/>

或类似 id="messageSource" 的 bean

<bean id="messageSource" class="org.springframework.context.support.ReloadableResourceBundleMessageSource">
    <property name="basenames">
    <list>
    <value>/WEB-INF/resources/messages</value>
    </list>
    </property>
    <property name="defaultEncoding" value="UTF-8" />
</bean>

找到messages.properties（或者基于config的东西.properties）后，你应该给它添加一个属性

menu_category__label=example label

您可以在Spring locale 阅读有关 Spring MVC 国际化的更多信息

认为它会有所帮助。
