以前端取資料庫的method為例

※pom.xml

※springMVC也要，因為listener是web的

※web.xml

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>
        /WEB-INF/applicationContext.xml
    </param-value>
</context-param>
    
<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
    
<servlet>
    <servlet-name>dwr</servlet-name>
    <servlet-class>org.directwebremoting.spring.DwrSpringServlet</servlet-class>
    <init-param>
        <param-name>debug</param-name>
        <param-value>true</param-value>
    </init-param>
</servlet>
    
<servlet-mapping>
    <servlet-name>dwr</servlet-name>
    <url-pattern>/dwr/*</url-pattern>
</servlet-mapping>

※注意官方寫的順序有錯

※context-param裡的param-value要記得改

※applicationContext.xml

    </dwr:configuration>
    
    <dwr:annotation-scan base-package="dao.impl.DaoImpl, vo.Chess"
        scanDataTransferObject="true" scanRemoteProxy="true" />
</beans>

※<dwr:url-mapping />有時候會報錯，但不影響執行

※這些設定可以參考上面的「前端取資料庫的method」連結裡面的設定，只是寫法不同而已

※bean class還是不能寫interface

※<dwr:remote>裡面全部不寫就是全部方法都可以用，可以用debug看，dwr會有紅字提示

※include和exclude是加方法和排除方法的意思，兩者只能選其一

※include和exclude可以寫沒有定義的方法
寫在include裡，又沒寫其他的方法，那就表示沒有方法可以用
寫在exclude裡，又沒寫其他的方法，那就表示所有方法都可以用，也就是等於不寫

※dwr.xml可以整個刪除了

※更詳細的要看官網，我只寫其中一個方法而已

※annotation的部分用最下面的即可，寫法和第六篇的annotation一樣
