Some more features.
So we have successfully completed our spring security integration with ZK Application as per the previous article.
In this post, we will add some more features to our application.
Define System Level users.
In the standard login based application, always there will be some users are defined as system and the end users of the application cannot modify or Delete those users from the system. That’s what we are going to do now.
As a first step, in the mysql table, add one more column as shown
As you can see, we have given default value for this column as zero. So any user created thru the application will have zero value. So users having system=0 will be treated as normal user and users having system=1 will be treated as system normal users. So in the back end itself, make some users are system by changing the value to 1.
Next step, we need add this new column in our domain object. In the zkexample.domain.UserProfile.java add this and include the getter and setter as shown.
private Integer system;
public Integer getSystem() {
return system;
}
public void setSystem(Integer system) {
this.system = system;
}
Next step, we need to modify our userList.zul. For system users, we will NOT show EDIT and DELETE action. We will only allow View option.
And also, we will see how we can use ZK Popup component for this use case.(Please refer here and here). For system users, we will show one more question mark image with popup bind to inform the user about this.
Update style.css
/* Start: Action Images- Auditlog
---------------------------------------------- */
.fImageAudit {
width: 25px;
background-image: url('../images/AuditLog.jpg');
background-repeat: no-repeat;
border: 0 none;
cursor: pointer;
}
And you need to have the QuestionmarkButton-16x16.png in the images folder
Here is the modified zul file
<?page title="Users List" contentType="text/html;charset=UTF-8"?>

<listheader label="Action" />
</listhead>
<template name="model" var="p1">
<listitem>
<listcell label="@load(p1.firstName)" />
<listcell label="@load(p1.lastName)" />
<listcell label="@load(p1.email)" />
<listcell label="@load(p1.userLoginID)" />
<listcell>
<hbox spacing="20px">

</template>
</listbox>
<popup id="msgPopup">
<label id="msg"
value="Sytem defined user. Edit and Delete are not allowed.">
</label>
</popup>
</window>
</zk>
List Data Filter.
Next we will add data filter option as shown in ZK Demo here. First let us add datafilter class in our project. Create one more class named as Datafilter under the zkoss package as shown.
package zkexample.zkoss;
public class DataFilter {
private String code = "";
private String firstName = "";
private String lastName = "";
private String email = "";
private String loginID= "";
public String getCode() {
return code;
}
public void setCode(String code) {
this.code = code == null ? "" : code.trim();
}
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName == null ? "" : firstName.trim();
}
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName == null ? "" : lastName.trim();
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email == null ? "" : email.trim();
}
public String getLoginID() {
return loginID;
}
public void setLoginID(String loginID) {
this.loginID = loginID == null ? "" : loginID.trim();
}
}
Next we need to add auxhead in our listing file. Here is the modified userList.zul and UserListVM
UserList.zul
<?page title="Users List" contentType="text/html;charset=UTF-8"?>
<zk>
<window id="userList" border="none" height="80%" width="96%"

<div sclass="sectionTitle">

<separator />
</div>
<div style="float:right">
<button label="Add New" onClick="@command('onAddNew')"
mold="trendy" sclass="mybutton button blue small" />
<button label="Logout" mold="trendy" id="btnlogout"
sclass="mybutton button blue small" onClick="@command('Logout')" />
</div>
<div style="clear: both;"></div>
<div sclass="sectionSeperator"></div>
</div>
