春天 + Tiles - 访问 jsp 文件夹时出现 404 错误

Question

基本上，当我启动项目时，视图都已正确解析，并且正在查找正确的 jsp，但是似乎有某些东西阻止了对 WEB-INF 文件夹内的 jsp 文件夹的访问。

确切的问题是，当我转到 localhost/FitterBlog/index.htm 时，出现 404 错误：

The requested resource (/FitterBlog/jsp/layout/layout.jsp) is not available.

我有以下代码：

import org.springframework.web.servlet.ModelAndView;

@Controller
public class MainController {

@RequestMapping(value="index.htm", method=RequestMethod.GET)
public ModelAndView index() {
    return new ModelAndView("index");
}
}

我已进行三次检查所有 JSP 文件都位于正确的位置，如出现 404 错误的 layout.jsp 文件位于 WEB-INF/jsp/layout/layout.jsp 中。

Answer 1

在我的应用程序中，jsp 位于 WEB-INF 的子目录中。

如果您的情况相同，则需要稍微更改图块配置

<tiles-definitions>
<definition name="baseLayout" template="/WEB-INF/jsp/layout/layout.jsp">
    <put-attribute name="title" value="FitterBlog" />
    <put-attribute name="header" value="/WEB-INF/jsp/layout/header.jsp" />
    <put-attribute name="nav" value="/WEB-INF/jsp/layout/nav.jsp" />
    <put-attribute name="body" value="" />
    <put-attribute name="footer" value="/WEB-INF/jsp/layout/footer.jsp" />
</definition>

<definition name="index" extends="baseLayout">
    <put-attribute name="body" value="/WEB-INF/jsp/index.jsp" />
</definition>   
</tiles-definitions>

Answer 2

如果您想将 JSP 存储在 WEB-INF 中，则只需在 ViewResolver 中设置 prefix 属性

<beanid="viewResolver" class="org.springframework.web.servlet.view.UrlBasedViewResolver">
  <property name="viewClass" value="org.springframework.web.servlet.view.tiles2.TilesView"/>
  <property name="prefix" value="/WEB-INF/jsp/"/>
  <property name="suffix" value=".jsp"/>
</bean>
