Spring SwitchUserFilter working in Spring Security XML file and web.xml - spring

Question

I have a problem of switchuser in spring. I am new for switchuser and not getting the right way to solve this.
Here is my code:
Spring-Security.xml
<beans:beans xmlns="http://www.springframework.org/schema/security" xmlns:beans="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security.xsd"> <http pattern="/index" security='none' />
<http pattern="/passwordrecovery" security='none' />
<beans:bean id="customAuthenticationSuccessHandler" class="com.ds4u.project.handler.CustomAuthenticationSuccessHandler"/>
<http auto-config="true" use-expressions="true"
authentication-manager-ref="authenticationManager">
<headers>
<cache-control />
</headers>
<custom-filter position="SWITCH_USER_FILTER" ref="switchUserProcessingFilter" />
<!-- role based URL protection -->
<intercept-url pattern="/admin/**" access= "hasRole('ROLE_ADMIN','ROLE_PREVIOUS_ADMINISTRATOR')" />
<intercept-url pattern="/user/**" access= "hasAnyRole('ROLE_USER','ROLE_ADMIN','ROLE_POWER_USER','ROLE_PATIENT')" />
<intercept-url pattern="/patient/**" access= "hasAnyRole('ROLE_USER','ROLE_ADMIN','ROLE_POWER_USER','ROLE_PATIENT')" />
<intercept-url pattern="/welcome/**" access= "hasAnyRole('ROLE_ADMIN','ROLE_NEW_PATIENT')" />
<intercept-url pattern="/poweruser/power**" access= "hasAnyRole('ROLE_ADMIN','ROLE_POWER_USER','ROLE_PROVIDER')" />
<intercept-url pattern="/provider/**" access= "hasAnyRole('ROLE_ADMIN','ROLE_POWER_USER','ROLE_PROVIDER')" />
<intercept-url pattern="/switchUser" access="hasAnyRole('ADMIN', 'ROLE_PREVIOUS_ADMINISTRATOR')"/>
<!-- It will handle user login authentication -->
<form-login login-page="/login" authentication-success-handler-ref="customAuthenticationSuccessHandler"
authentication-failure-url="/loginerror"/>
<logout logout-success-url="/" logout-url="/jlogout" delete-cookies="JSESSIONID"/>
<!-- csrf prtoection configuration -->
<csrf disabled="true" />
<!-- unauthorized access handler -->
<access-denied-handler error-page="/accessdenied" />
</http>
<beans:bean id="switchUserProcessingFilter" class="org.springframework.security.web.authentication.switchuser.SwitchUserFilter">
<beans:property name="userDetailsService" ref="com.ds4u.project.service.UserDetailServiceImpl"/>
<beans:property name="switchUserUrl" value="/admin/impersonate"/>
<beans:property name="targetUrl" value="/admin/adminProvider"/>
<beans:property name="switchFailureUrl" value="/admin/switchUser"/>
<beans:property name="successHandler" ref="authenticationManager" />
</beans:bean>
<authentication-manager id="authenticationManager">
<authentication-provider>
<password-encoder ref="encoder"/>
<jdbc-user-service data-source-ref="DatabaseName"
users-by-username-query="
select UserName,Password, IsEnable from user where UserName = ? and IsEnable in(1,4)"
authorities-by-username-query=" select u.username, ur.authority from user u,
authorities ur where u.authorityId = ur.id and u.username =? " />
</authentication-provider>
</authentication-manager>
<beans:bean id="encoder" class="org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder">
<beans:constructor-arg name="strength" value="10" />
</beans:bean></beans:beans>
What will be the swithuserurl, targetUrl, switchFailureUrl, successHandler in switchuserprocessingfilter bean?
My Web.XML is.
<filter><filter-name>springSecurityFilterChain</filter-name>
<filter-class>org.springframework.web.filter.DelegatingFilterProxy
</filter-class>
</filter>
<filter><filter-name>switchUserProcessingFilter</filter-name>
<filter-class>
org.springframework.security.web.authentication.switchuser.SwitchUserFilter
</filter-class>
</filter>
<filter-mapping><filter-name>springSecurityFilterChain</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<filter-mapping><filter-name>switchUserProcessingFilter</filter-name>
<url-pattern>/"what can be put here?"</url-pattern>
</filter-mapping>
In web.xml what will be the filterMapping for switchUserProcessingFilter filter name?
My CustomAuthenticationSuccessHandler code is---
public class CustomAuthenticationSuccessHandler implements AuthenticationSuccessHandler{
private RedirectStrategy redirectStrategy = new DefaultRedirectStrategy();
public void onAuthenticationSuccess(HttpServletRequest request,
HttpServletResponse response, Authentication authentication) throws IOException,
ServletException {
HttpSession session = request.getSession();
/* Set some session variables */
User authUser = (User) SecurityContextHolder.getContext().getAuthentication().getPrincipal();
session.setAttribute("uname", authUser.getUsername());
session.setAttribute("auhtorities", authUser.getAuthorities());
/* Set target url to redirect */
String targetUrl = determineTargetUrl(authentication);
redirectStrategy.sendRedirect(request, response, targetUrl);
}
protected String determineTargetUrl(Authentication authentication){
Set<String> authorities = AuthorityUtils.authorityListToSet(authentication.getAuthorities());
if(authorities.contains("ROLE_USER")){
return "/user/userhome";
}else if(authorities.contains("ROLE_ADMIN")){
return "/admin/home";
}else if(authorities.contains("ROLE_POWER_USER")){
return "/poweruser/poweruserhome";
}
else if(authorities.contains("ROLE_PATIENT")){
return "/patient/home";
}
else if(authorities.contains("ROLE_PROVIDER")){
return "/provider/home";
}
else if(authorities.contains("ROLE_NEW_PATIENT")){
return "/welcome/home";
}
return "accessdenial.do";
}
public RedirectStrategy getRedirectStrategy() {
return redirectStrategy;
}
public void setRedirectStrategy(RedirectStrategy redirectStrategy) {
this.redirectStrategy = redirectStrategy;
}
}
What will be the code in userdetailsservice class as it reference in switchUserProcessingFilter bean in security xml?
When I was running this code then it gives me the error like:
Error creating bean with name
'org.springframework.security.filterChains': Cannot resolve reference
to bean
'org.springframework.security.web.DefaultSecurityFilterChain#2'
I copied SWITCHUSERFILTER from Google and somewhere but it is not processing and is giving errors.
