How to inject spring beans into xhtml page

How to inject spring beans into xhtml page - java

I am working with Spring and I have a problem with a bean, here is my code:
import org.springframework.stereotype.Component;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import com.grh.bo.ICollaborateurBo;
import com.grh.bo.IUserBo;
import com.grh.entities.Collaborateur;
#Component
#Scope("session")
public class CollaborateurBean implements Serializable {
private static final long serialVersionUID = 1L;
#Autowired
private ICollaborateurBo collaborateurBo;
private String nom;
private String prenom;
private String sflag = "";
private int currentProjectIndex;
private int page = 1;
public List<Collaborateur> listOfCollaborateur = new ArrayList<Collaborateur>();
private Collaborateur Collaborateurr = new Collaborateur();
List<Collaborateur> lis = new ArrayList<Collaborateur>(collaborateurBo.getAllCollaborateur());
#PostConstruct
public void init() {
setListOfCollaborateur(recupererCollaborateur());
Collaborateurr=new Collaborateur();
}
public List<Collaborateur> getLis() {
return collaborateurBo.getAllCollaborateur();
}
public void setLis(List<Collaborateur> lis) {
this.lis = lis;
}
public List<Collaborateur> getCollaborateurList() {
return collaborateurBo.getAllCollaborateur();
}
private List<Collaborateur> recupererCollaborateur() {
List<Collaborateur> ps = collaborateurBo.getAllCollaborateur();
return ps;
}
public CollaborateurBean() {
super();
}
public CollaborateurBean(ICollaborateurBo collaborateurBo, String nom,
String prenom, String sflag, int currentProjectIndex, int page,
List<Collaborateur> listOfCollaborateur,
Collaborateur collaborateurr, List<Collaborateur> lis) {
super();
this.collaborateurBo = collaborateurBo;
this.nom = nom;
this.prenom = prenom;
this.sflag = sflag;
this.currentProjectIndex = currentProjectIndex;
this.page = page;
this.listOfCollaborateur = listOfCollaborateur;
Collaborateurr = collaborateurr;
this.lis = lis;
}
public Collaborateur getCollaborateurr() {
return Collaborateurr;
}
public void setCollaborateurr(Collaborateur collaborateurr) {
Collaborateurr = collaborateurr;
}
public List<Collaborateur> getListOfCollaborateur() {
return listOfCollaborateur;
}
public void setListOfCollaborateur(List<Collaborateur> listOfCollaborateur) {
this.listOfCollaborateur = listOfCollaborateur;
}
public String getSflag() {
return sflag;
}
public void setSflag(String sflag) {
this.sflag = sflag;
}
public void setCollaborateurBo(ICollaborateurBo collaborateurBo) {
this.collaborateurBo = collaborateurBo;
}
public ICollaborateurBo getCollaborateurBo() {
return collaborateurBo;
}
public int getPage() {
return page;
}
public void setPage(int page) {
this.page = page;
}
public int getCurrentProjectIndex() {
return currentProjectIndex;
}
public void setCurrentProjectIndex(int currentProjectIndex) {
this.currentProjectIndex = currentProjectIndex;
}
public String getNom() {
return nom;
}
public void setNom(String nom) {
this.nom = nom;
}
public String getPrenom() {
return prenom;
}
public void setPrenom(String prenom) {
this.prenom = prenom;
}
}
in this page collaborateur.xhtml i Can't display data from my DATABASE collaborateur.xhtml:
<h:dataTable value="#{CollaborateurBean.getLis()}" var="item">
<h:column>
<h:outputText value="#{item.nom}" />
</h:column>
<h:column>
<h:outputText value="#{item.prenom}" />
</h:column>
</h:dataTable>
When I test the collaborateurBo i display data from my DATABASE. This is the code that gives data from database:
<h:dataTable value="#{collaborateurBo.getAllCollaborateur()}" var="item">
<h:column>
<h:outputText value="#{item.nom}" />
</h:column>
<h:column>
<h:outputText value="#{item.prenom}" />
</h:column>
</h:dataTable>
This means that the problem is in the Collaborateur bean not in collaborateurBo or CollaborateurDao.
Here my configurations :

(edited from a previous version)
I created a simplified setting for your problem, and got the code to work.
Here are the two Java classes, first the service (in essense a stub, I did not try to simplify it further, the code has no particular significance):
package com.anzy.services;
import java.util.ArrayList;
import java.util.Collection;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
#Service("userDetailsService")
public class UserDetailsServiceImpl implements UserDetailsService
{
#Transactional(readOnly=true)
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException
{
Collection <GrantedAuthority> authorities=new ArrayList<GrantedAuthority>();
authorities.add(new SimpleGrantedAuthority("ROLE_USER"));
org.springframework.security.core.userdetails.User secureUser=new org.springframework.security.core.userdetails.User("user", "user", true, true, true, true, authorities);
return secureUser;
}
}
and here is the controller (again, simplified to have just one method)
package com.anzy.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
#Controller
public class DataController {
#RequestMapping("form")
public ModelAndView getForm() {
return new ModelAndView("form");
}
}
the four files under WEB-INF are:
spring-config.xml

Don't use s:action tag in JSP, until you know how and why to do that. To display values in JSP you are not needed it at all. You should use struts tags to access action bean properties. For example you can print values to the JSP out using s:property tag. For example
<s:iterator value="beans">
id: <s:property value="id"/><br>
Book: <s:property value="book"/><br>
Author: <s:property value="author"/><br>
Availbleqty: <s:property value="availbleqty"/><br>
Category: <s:property value="category"/><br>
<s:/iterator>
The FilterDispatcher is deprecated and you should replace it with StrutsPrepareAndExecuteFilter. See web.xml docs. Also see this answer for
Need suggestions regarding project implementation in Struts and Hibernate.

Change your web.xml and stuts.xml as below.
Struts.xml
<struts>
<constant name="struts.devMode" value="true" />
<package name="a" namespace="/" extends="struts-default">
<action name="" class="Action.ActionTest" method="viewbookaction">
<result name="success">/BookView.jsp</result>
</action>
</package>
web.xml
<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
That's all. Simply run.

I have a 404 from this but I'm sure I am missing something small but I haven't been able to figure it out yet. Any ideas?

public void setPassword(String password) {
this.password = password;
}
}
My Code is working well but it does not displays error messages in <form:errors />.
please help me.

The third parameter to ValidationUtils.rejectIfEmpty is an error code. It should be a key to the actual message in your resource bundle. I don't know how it behaves if it can't find a value. You should change it to use a key, and optionally set a default message. See the api.

You need to register your validator with the controller in which you want to use it. See: http://static.springsource.org/spring/docs/3.0.0.RC3/reference/html/ch05s07.html#validation.mvc
