dwr 开发搭建

引入jar

<!-- DWR的jar包  -->
<dependency>
  <groupId>org.directwebremoting</groupId>
  <artifactId>dwr</artifactId>
  <version>2.0.3</version>
</dependency>

前端引入

<script type="text/javascript" src="dwr/interface/BeanUtil.js"></script>（自定义）
<script type="text/javascript" src="dwr/engine.js"></script>（系统自带）
<script type="text/javascript" src="dwr/util.js"></script>

调用方式

<script>
    BeanUtil.getBase64("j=123",function (res) {
        console.log(res);
    });
</script>

在web.xml中加入dwr 的servlet

<servlet>
  <servlet-name>dwr-invoker</servlet-name>
  <servlet-class>uk.ltd.getahead.dwr.DWRServlet</servlet-class>
  <init-param>
    <param-name>debug</param-name>
    <param-value>true</param-value>
  </init-param>
  <init-param>
    <param-name>scriptCompressed</param-name>
    <param-value>false</param-value>
  </init-param>
  <init-param>
    <param-name>crossDomainSessionSecurity</param-name>
    <param-value>false</param-value>
  </init-param>
  <!-- 是servlet的加载顺序 数字越小代表加载的优先级越高 -->
  <load-on-startup>1</load-on-startup>
</servlet>

在web.xml同目录加入dwr.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE dwr PUBLIC
        "-//GetAhead Limited//DTD Direct Web Remoting 2.0//EN"
        "http://getahead.org/dwr/dwr20.dtd">
<dwr>
  <allow>
    <create creator="new" javascript="BeanUtil">
      <param name="class" value="com.util.BeanUtil"/>
    </create>
  </allow>
</dwr>
