服务类UserManager.java
public class UserManager {
Logger log = Logger.getLogger(UserManager.class);
// id,name为页面提交来的字段
public String login(String id, String name) {
log.info(">>>UserManager.logins");
return id + name + " Login success !";
}
// user为页面提交来的对象
public User getCustomreObj(User user) {
System.out.println(user.getId());
System.out.println(user.getName());
return user;
}
//arg为页面提交来的Map对象
public Map object(Map arg) {
return arg;
}
}
写这文章主要是为了说明这个无参的构造器很重要，u[Buffalo.BOCLASS] = "com.java.bean.User"时要用到，
要不会报错 fail to initialize type......
public class User implements Serializable {
private String id;
private String name;
public User() {
}
public User(String id, String name) {
this.id = id;
this.name = name;
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
<script language="javascript">
var endPoint="<%=request.getContextPath()%>/bfapp";
var buffalo = new Buffalo(endPoint);
//提交字段
function login() {
var id=$("id").value;
var name=$("name").value;
//alert(id+name);
buffalo.remoteCall("userService.login", [id,name], function(reply){
$("form_infomsg").innerHTML=reply.getResult();
})
}
//提交对象
function submitObj(){
var userObj = Buffalo.Form.formToBean("form1", "com.java.bean.User");//buffalo实现form表单元素绑定是一对一的，form里包含多余的元素会报错
buffalo.remoteCall("userService.getCustomreObj", [userObj], function(reply){
$("form_infomsg").innerHTML="obj："+reply.getResult().id+"-"+reply.getResult().name;
})
}
function submitMap() {
var a = {};
a[Buffalo.BOCLASS] = "java.util.Map";
a["a"] = "A";
a["b"] = true;
a["c"] = 123.4;
var u = {};
u[Buffalo.BOCLASS] = "com.java.bean.User";
u.id = "234";
