Spring3MVC:Themes in Spring-Tutorial with Example

我们的目的为了改变Hello World Spring3MVC，添加对主题的支持，用户将可以选择主题从预定义的主题中，（default，black，blue）

添加主题支持，在spring3MVC中

添加下面的代码到spring-servlet.xml中

File: WebContent/WEB-INF/spring-servlet.xml

<bean id="themeSource"

    class="org.springframework.ui.context.support.ResourceBundleThemeSource">

        <property name="basenamePrefix" value="theme-" />

</bean>

 

<!-- Theme Change Interceptor and Resolver definition -->

<bean id="themeChangeInterceptor"

    class="org.springframework.web.servlet.theme.ThemeChangeInterceptor">

    <property name="paramName" value="theme" />

</bean>

<bean id="themeResolver"

    class="org.springframework.web.servlet.theme.CookieThemeResolver">

    <property name="defaultThemeName" value="default" />

</bean>

 

 

<bean id="handlerMapping"

    class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping">

    <property name="interceptors">

        <list>

            <ref bean="localeChangeInterceptor" />

            <ref bean="themeChangeInterceptor" />

        </list>

    </property>

</bean>

File: resources/theme-default.properties

css=themes/default.css

File: resources/theme-blue.properties

css=themes/blue.css

File: resources/theme-black.properties

css=themes/black.css

为不同的主题设定不同的css

让我们创建css文件在WebContent/themes目录中

File: WebContent/themes/default.css

body {

    background-color: white;

    color: black;

}

File: WebContent/themes/blue.css

body {

    background-color: #DBF5FF;

    color: #007AAB;

}

File: WebContent/themes/black.css

body {

    background-color: #888;

    color: white;

}

File: WebContent/WEB-INF/jsp/header.jsp

<%@taglib uri="http://www.springframework.org/tags" prefix="spring"%>

<%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>

 

 

<h3><spring:message code="label.title"/></h3>

 

<span style="float: right">

    <a href="?lang=en">en</a>

    |

    <a href="?lang=de">de</a>

</span>

 

 

<span style="float: left">

    <a href="?theme=default">def</a>

    |

    <a href="?theme=black">blk</a>

    |

    <a href="?theme=blue">blu</a>

</span>

程序运行ok！
