dwr 3.0 配置 + 不同参数，不同返回值调用方法 示例
配置方法：
1 官网 dwr.jar包
2 web.xml
<!-- dwr --> <listener> <listener-class>org.directwebremoting.servlet.DwrListener</listener-class> </listener> <servlet> <servlet-name>dwr-invoker</servlet-name> <servlet-class>org.directwebremoting.servlet.DwrServlet</servlet-class> <init-param> <description></description> <param-name>debug</param-name> <param-value>true</param-value> </init-param> </servlet>
3 dwr.xml
A 和spring 整合
<dwr> <allow> <create creator="spring" javascript="dwrService" > <param name="beanName" value="dwrServiceImpl" ></param> </create> <create creator="spring" javascript="basicDwrService" > <param name="beanName" value="basicDwrServiceImpl" ></param> </create> <convert match="com.ass.common.generated.model.TUser" converter="bean" /> </allow> </dwr>
B 没有和spring整合
<dwr> <allow> <create creator="new" javascript="testClass" > <param name="class" value="/com.dwr.TestClass" /> <include method="testMethod1"/> </create> </allow> </dwr>
4 jsp页面引用
<script type='text/javascript' src="${root }dwr/engine.js"></script>
<script type='text/javascript' src="${root }dwr/util.js"></script>
<script type='text/javascript' src="${root }dwr/interface/dwrService.js"></script>
***********************上面配置网上一大堆，重点是下面使用范例*****************************************************************************
1 jsp页面写法 和 2 后台写法
1：
<script type="text/javascript">
function testStr(){
console.info("begin test str");
dwrService.testStr("wangt",function(data){console.info(data)});
}
function testMap(){
//*******Map参数写法1 begin
var data = {
u : 'username',
p : 'password'
}
//*******Map参数写法1 end
//*******Map参数写法2 begin
var d = new Object();
d.name = 'aa';
d.sdf='ss';
//*******Map参数写法2 end
console.info(d);
console.info(data);
dwrService.testMap(d, function(data){
console.info(data);
console.info(data.ok);
})
}
function testshuzu(){
var a = new Array();
a[0] = "1";
a[1] = "2";
a[2] = "3";
dwrService.testShuzu1(a,function(d){//return String[]
console.info(d);
console.info(d[0]);
})
dwrService.testShuzu2(a,function(d){//return List<String>
console.info(d);
console.info(d[0]);
})
}
function testList(){
var lst = [];
//var a = {name : "aname", password: 'paassword'};
//var b = {name : "bname", password: 'bpassword'};
var a = new Object();
var b = new Object();
a.name = "aname";
a.password = "apassword";
b.name = "bname";
b.password = "bpassword";
lst[0] = a;
lst[1] = b;
console.info(lst);
dwrService.testList(lst, function(da){
console.info(da);
console.info(da[0]);
console.info(da[0].ok);
})
}
function testuser(){
var u = new Object();
u.name="uname";
dwrService.testUser(u,function(d){
console.info(d);
console.info(d.name);
})
}
</script>
