我正在使用Struts 2來註冊用戶。如何在Struts 2中使用Ajax調用獲得成功後重定向到另一個JSP
我正在使用Ajax調用註冊用戶，獲得註冊後我可以在Ajax調用中獲得成功函數的成功消息。但它沒有得到重定向到基於struts.xml的其他JSP結果type=success。
register.jsp：
<s:form id="form">
<s:textfield name="email" id="email" label="Email" required="true" onkeyup="loadXMLDoc()" onblur="userNameCheck()"></s:textfield>
<s:textfield name="mobile" id="mobile" label="Mobile"></s:textfield>
<s:textfield name="username" id="username" readonly="true"
label="Username"></s:textfield>
<s:textfield name="first_name" id="first_name"
label="First Name"></s:textfield>
<s:textfield name="last_name" id="last_name"
label="Last Name"></s:textfield>
<s:password name="password" id="password" label="Password"></s:password>
<s:password name="uconfirm_password" id="confirm_password"
label="Confirm"></s:password>
<div class="button">
<input type="reset" name="cancel" id="cancel" value="Cancel">
<input type="submit" name="save" id="save" value="Save">
</div>
</s:form>
Ajax調用：
$.ajax({ // Ajax function to call the action
type : 'POST',
contentType : 'application/json',
url : 'user',
dataType : "html",
data : registerFormToJSON(),
success : function(html) {
alert("Successfully Registered");
},//End of success function in ajax call
error : function(err) {
console.log("Fail");
return true;
} //End of error function in ajax call
});
return false;
}
});
function registerFormToJSON() {
var data = JSON.stringify({
"userbean" : {
"username" : $("#username").val(),
"password" : $("#password").val(),
"firstname" : $("#first_name").val(),
"lastname" : $("#last_name").val(),
"confirmpassword" : $("#confirm_password").val(),
"email" : $("#email").val(),
"mobile" : $("#mobile").val(),
}
}); //End of getting form values and storing in json variable
alert(data);
return data;
}//End of function registerFormToJSON()
動作類方法：
public class UserController implements Action {
private UserBeans userbean;
/**
* @return the userbean
*/
public UserBeans getUserbean() {
return userbean;
}
/**
* @param userbean
* the userbean to set
*/
public void setUserbean(UserBeans userbean) {
this.userbean = userbean;
}
@Override
public String execute() {
return SUCCESS;
}
public String register() {
UserService service = new UserServiceImpl();
userbean = service.addorUpDateUser(userbean);
// response.setContentType("json");
return ActionSupport.SUCCESS;
}
}
DAO類方法：
public UserBeans addOrUpdateUser(UserBeans userBean) {
properties.load(inputStream);
con = conn.createConnection();
System.out.println("name is mine" + userBean.getUsername());
String encryptedPassword = PasswordUtil.encryptPassword(userBean.getPassword());
String query = properties.getProperty("users_query");
System.out.println(query);
System.out.println("connection:" + con);
preparedstatement = con.prepareStatement(query);
preparedstatement.setString(1, userBean.getUsername());
preparedstatement.setString(2, encryptedPassword);
preparedstatement.setString(3, userBean.getEmail());
preparedstatement.setString(4, userBean.getFirstname());
preparedstatement.setString(5, userBean.getLastname());
preparedstatement.setString(6, userBean.getMobile());
preparedstatement.setString(7, userBean.getConfirmpassword());
preparedstatement.executeUpdate(); // execute insert statement
logger.info("UserDaoImpl addOrUpDate Ends");
return userBean;
}
