Question

我正在尝试减少Web应用程序的某些配置，并注意到我们的views.properties文件有很多可以通过编程方式计算的冗余值。

例如：

welcome.(class)=org.springframework.web.servlet.view.tiles2.TilesView
welcome.url=welcome

home.(class)=org.springframework.web.servlet.view.tiles2.TilesView
home.url=home

login.(class)=org.springframework.web.servlet.view.tiles2.TilesView
login.url=login

有没有任何方法可以在没有views.properties文件的情况下完全执行此操作（我更倾向于认为“文件名必须与视图名称匹配”，而不是容易出错的“更新这些x配置文件”）

谢谢你的时间！

所以我一直在用hack来摆脱蹩脚的views.properties文件大约6年了。这是我为所有人嘲笑/使用的惊人解决方案：

以这种方式定义viewResolver

<bean id="viewResolver" class="com.yourcompany.util.TilesResourceBundleViewResolver"/>

以下是直接查看切片视图的解析器的实现

package com.yourcompany.util;

import java.util.Locale;
import java.util.MissingResourceException;
import javax.servlet.http.HttpServletRequest;
import org.apache.struts.tiles.DefinitionsFactory;
import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContextException;
import org.springframework.web.servlet.View;
import org.springframework.web.servlet.view.tiles.TilesView;
import org.apache.struts.tiles.DefaultTilesUtilImpl;
import org.springframework.mock.web.MockHttpServletRequest;
import org.springframework.web.servlet.view.AbstractCachingViewResolver;

/**
 * Dave's improved view resolver because he hates having too many files to
 * update every time he creates a new view. Spring already makes it bad enough!
 *
 * @author dave
 */
public class TilesResourceBundleViewResolver extends AbstractCachingViewResolver
{
    private final String CONTENT_TYPE = "text/html;charset=utf-8";

    /**
     * for some incomprehensible reason the tiles stuff requires an http request
     * in order to see if a view exists.
     */
    private static final HttpServletRequest FAKE_HTTP_REQUEST =
        new MockHttpServletRequest();

    @Override
    protected View loadView(String viewName, Locale locale) throws
        MissingResourceException, BeansException, Exception
    {
        // check if the view is defined
        // in the site-views.xml and let tiles worry about it
        DefinitionsFactory definitionsFactory =
            (DefinitionsFactory) getServletContext().getAttribute(
                DefaultTilesUtilImpl.DEFINITIONS_FACTORY);
        if (definitionsFactory == null)
        {
            throw new ApplicationContextException(
                "Tiles definitions factory not found: TilesConfigurer not defined?");
        }
        if (definitionsFactory.getDefinition(viewName,
            FAKE_HTTP_REQUEST, getServletContext()) == null)
        {
            //log.warn("Request for unknown view: " + viewName);
            viewName = "PageNotFound";
        }

        TilesView t = new TilesView();
        t.setBeanName(viewName);
        t.setUrl(viewName);
        t.setApplicationContext(getApplicationContext());
        t.setContentType(CONTENT_TYPE);
        return t;
    }
}

使用没有`views.properties`的Tiles
