我在使用 Spring 时遇到了非常具体的问题。如果我在我的 web.xml 中保留 metadata-complete="true"，我的应用程序的工作就是一个魅力。但如果我把它弄错了，spring 就无法找到瓷砖定义。

我的代码库版本如下： Spring MVC: 4.3.4.RELEASE Tiles: 3.0.7 web-app: 3.0

应用程序结构：一个 EAR 项目，在主 Web 应用程序中包含 4 个 Web 片段 jar 和 1 个 EJB。

我的 web.xml 如下

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
         version="3.0" metadata-complete="true">

Finally I got the answer after debugging the spring source and tiles source files.

The problem was with fragmented project structure. Due to fragmented project structure we had spring Dispatcher servlet xml in each fragment. Now spring has one bug: When web.xml has "metadata-complete="false"", spring is also searching it's dispatcher servlet xml in fragment projects. But the tiles definition is getting overridden from the last dispatcher servlet's configuration. So, the last fragment's tiles definition files are loaded. All previous definition files are dropped.

Quick Solution: Keep all tiles definition files in parent dispatcher servlet xml and all fragment project should not contain it's own configuration.

long term solution: It need to be done by Spring community. Instead of replacing the configuration, spring should merge all of them and create one master despatcher before initializing the application.
