Securing GWT servlets with Spring Security - spring

Question

I'm writing a GWT application secured with Spring security. Logging in works fine, but authorization doesn't.
I've tried using #Secured and #PreAuthorize annotations on my methods and that didn't work either.
For instance, this is a code snippet from AppUserServiceImpl
#Secured("ROLE_ADMINISTRATOR")
#Override
public List<AppUser> fetch(Integer startRow, Integer endRow, Map criteria) {
return appUserManagerBean.getUsers(criteria);
}
ApplicationContext.xml
<?xml version="1.0" encoding="UTF-8"?>
<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-3.0.xsd
http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security-3.0.xsd">
<http auto-config="true">
<intercept-url pattern="/testapplication/**" access="ROLE_USER"/>
<intercept-url pattern="/gwt/**" access="ROLE_USER"/>
<intercept-url pattern="/**/*.html" access="ROLE_USER"/>
<intercept-url pattern="/**" access="IS_AUTHENTICATED_ANONYMOUSLY" />
<intercept-url pattern="/security/*" access="IS_AUTHENTICATED_ANONYMOUSLY" />
<intercept-url pattern="/testapplication/appUserService*" access="ROLE_ADMIN"/>
<form-login
login-page="/login.jsp"
authentication-failure-url="/security/error.html"
login-processing-url="/j_spring_security_check"
/>
</http>
<beans:bean id="appUserService" class="com.test.testapplication.server.admin.appuser.AppUserServiceImpl"/>
<beans:bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
[DATASOURCE CONFIGURATION]
</beans:bean>
<global-method-security pre-post-annotations="enabled" secured-annotations="enabled" />
<authentication-manager>
<authentication-provider>
<password-encoder hash="sha" />
<jdbc-user-service data-source-ref="dataSource"
users-by-username-query="select username,password,DECODE(enabled,'Y',1,'N',0) as enabled from APP_USER where username=?"
authorities-by-username-query="select u.username, ur.role from APP_USER u, APP_USER_ROLE ur
where u.id = ur.APP_USER_ID and u.username =? "
/>
</authentication-provider>
</authentication-manager>
To test, I'm trying to secure 'appUserService'.
web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

version="2.5">
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
/WEB-INF/applicationContext.xml
</param-value>
</context-param>
<servlet>
<servlet-name>appUserService</servlet-name>
<servlet-class>com.test.testapplication.server.admin.appuser.AppUserServiceImpl</servlet-class>
</servlet>
<!-- Spring security filter -->
<filter>
<filter-name>springSecurityFilterChain</filter-name>
<filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
</filter>
<filter-mapping>
<filter-name>springSecurityFilterChain</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<!-- Spring listener -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!-- Default page to serve -->
<welcome-file-list>
<welcome-file>testapplication.html</welcome-file>
</welcome-file-list>
I'm looking for the simplest solution and I would prefer not to use AspectJ, help would be greatly appreciated

Answer 1

Where are you mapping your servlet to particular path?
I'm using gwt-sl for integration of RemoteServiceServlets and Spring.
Define Dispatcher servlet in your web.xml:
<servlet>
<servlet-name>gwtservice</servlet-name>
<servlet-class> org.springframework.web.servlet.DispatcherServlet </servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
And declaration and mapping for your gwt-servlet:
<bean name="DeviceListenerServlet" class="your.package.your.SomeService"/>
<bean id="urlMappingGWT" class="org.gwtwidgets.server.spring.GWTHandler">
<property name="mappings">
<map>
<entry key="/service" value-ref="DriverServiceImpl"/>
</map>
</property>
</bean>
And change Annotation in your RemoteService class (in my example it will be #RemoteServiceRelativePath("gwtservice/service")).
Now you can use you #Secured annotation (if you added )
Hope this help.
