初玩Buffalo

页面调用服务器的一个类里面的方法，做下面的步骤就可以了，前提是你配置好了buffalo那个demo。
只需执行下面三个步骤，就可以完成一个简单的乘法调用。

=====================
Spring例子（使用于1.2以前的版本）
=====================
1）  HTML页面上
/buffalo/WebContent/pages/simple.html

增加页面输入框

<h4>1 Multipy calculator</h4>
<p>
  <input name="double4" type="text" class="input_text" id="double4" size="12">
  *
  <input name="double5" type="text" class="input_text" id="double5" size="12">
  <input type="button" name="Submit" value=" = " onclick="cmdMulitply()">
  <input name="double6" type="text" class="input_text" id="double6">
</p>

增加JS调用
function cmdMulitply(){
   var double4 =parseFloat(Buffalo.getElementById("double4").value);
   var double5 =parseFloat(Buffalo.getElementById("double5").value);
   var d6Handle =Buffalo.getElementById("double6");
  
   buffalo.remoteCall("hnisi_service.multiply",[double4,double5], function(reply) {
  d6Handle.value = reply.getResult();
  
  alert(reply.getResult());
 })
}

2）/buffalo/JavaSource/demo/buffalo-service.properties文件
加入
# 调整所有的Service
hnisi_service=net.buffalo.demo.hnisi.HnisiService

3）/buffalo/JavaSource/demo/net/buffalo/demo/hnisi/HnisiService.java
增加multiply方法

package net.buffalo.demo.hnisi;

public class HnisiService {

 public double multiply(double a, double b) {
  System.out.println("Calling Multipy...,a="+a+", b="+b+"    结果="+a*b);
  try {
   Thread.sleep(1000);
  } catch (Exception e) {
   e.printStackTrace();
  }
  return a*b;
 }
}

=====================
Spring例子
=====================
Buffalo的1.2版本加入了Spring功能，如果你想使用Spring特性，上述的过程如下：
1）  HTML页面上
/buffalo/WebContent/pages/simple-spring-2.html

增加页面输入框

<h4>1 Multipy calculator</h4>
<p>
  <input name="double4" type="text" class="input_text" id="double4" size="12">
  *
  <input name="double5" type="text" class="input_text" id="double5" size="12">
  <input type="button" name="Submit" value=" = " onclick="cmdMulitply()">
  <input name="double6" type="text" class="input_text" id="double6">
</p>

增加JS调用
function cmdMulitply(){
   var double4 =parseFloat(Buffalo.getElementById("double4").value);
   var double5 =parseFloat(Buffalo.getElementById("double5").value);
   var d6Handle =Buffalo.getElementById("double6");
  
   buffalo.remoteCall("hnisi_service.multiply",[double4,double5], function(reply) {
  d6Handle.value = reply.getResult();
  
  alert(reply.getResult());
 })
}

2）/buffalo/JavaSource/demo/buffalo-service.properties文件
加入
# 调整所有的Service
hnisi_service=net.buffalo.demo.hnisi.HnisiService

3）/buffalo/JavaSource/demo/net/buffalo/demo/hnisi/HnisiService.java
增加multiply方法

package net.buffalo.demo.hnisi;

public class HnisiService {

 public double multiply(double a, double b) {
  System.out.println("Calling Multipy...,a="+a+", b="+b+"    结果="+a*b);
  try {
   Thread.sleep(1000);
  } catch (Exception e) {
   e.printStackTrace();
  }
  return a*b;
 }
}

4）修改/buffalo/WebContent/WEB-INF/applicationContext.xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">

<beans>
 
 <bean name="simpleService" class="net.buffalo.demo.simple.SimpleService"></bean>
 <bean name="hnisiService" class="net.buffalo.demo.hnisi.HnisiService"></bean>
 <bean name="numberService" class="net.buffalo.demo.numberguess.NumberGuessService"></bean>
 
 <bean name="buffaloConfigBean" class="net.buffalo.service.BuffaloServiceConfigurer">
  <property name="services">
            <map>
                <entry key="springSimpleService">
                    <ref bean="simpleService"/>
                </entry>
     <entry key="springNumberService">
                    <ref bean="numberService"/>
                </entry>
                <entry key="springHnisiService">
                 <ref bean="hnisiService"/>
                </entry>
            </map>
        </property>
 </bean>
 
</beans>

总体感觉是简洁，无须关注xmlhttp，告别xml让我感到有点欣慰。
