    @RequestMapping(value="/chat")
    public String index()
    {
        System.out.println("**************");
        return "home";
    }
}

Please help..thanks in advance..

HelloWorldController类中缺少批注。

Give Order to you tiles view resolver So that you can define other view resolvers as well in case you are returning any view from controller which is not mapped. from your Controller you are returning "home". Which is not mapped in tiles.xml. Change it to "chat" and you will see the chat.jsp coming with header and footer as It is mapped in tiles.xml.

<bean id="viewResolver"
          class="org.springframework.web.servlet.view.UrlBasedViewResolver">
        <property name="viewClass">
            <value>
                org.springframework.web.servlet.view.tiles3.TilesView
            </value>
        </property>
        <property name="order" value="0" />
    </bean>

You should also add below to map only single jsp without tile

<bean id="jspViewResolver"
      class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="prefix">
        <value>/WEB-INF/views/</value>
    </property>
    <property name="suffix">
        <value>.jsp</value>
    </property>

    <property name="order" value="1"/>
</bean>
