Spring Security OAuth2 get Access Denied on REST Service

I am trying to secure my Spring REST Services with Spring security and OAuth2. I managed to get the tokens:
tokens
But when I try to get an secured rest service I get access denied:

Can anybody tell me why this is happening?

Thanks in advance!

Got this working. My problem was that in the application.config file I added /api so that for all my services an api folder is in place like: http://localhost:8080/api/about .. in my ResourceServerConfig class I added /api/** as requestMatchers and antMatchers.... the sercurity configuration is looking for serverice after this api prefix folder.... so exposing my about rest is done in this way:
#Configuration
#EnableResourceServer
public class ResourceServerConfig extends ResourceServerConfigurerAdapter {
private static final String RESOURCE_ID = "SPRING_REST_API";
#Override
public void configure(ResourceServerSecurityConfigurer resources) {
resources.resourceId(RESOURCE_ID).stateless(false);
}
#Override
public void configure(HttpSecurity http) throws Exception {
http.
anonymous().disable()
.requestMatchers().antMatchers("/about/**")
.and().authorizeRequests()
.antMatchers("/about/**").access("hasRole('ADMIN')")
.and().exceptionHandling().accessDeniedHandler(new OAuth2AccessDeniedHandler());
}
}
By the way.. I can request the about service with a parameter like in my request screenshot but it works also if i provide the authorization token als a Bearer Token authorization header....
Regards!

Java Spring initialize, call a method on startup

I am new to java spring framework, and I am trying to call a method or initialize a method on startup so when the application start, I will be able to see my data from the database on my jsp page. I have try #EventListener, #PostConstruct but nothing is working for me.
This is my WebConfigura class
#Configuration
#ComponentScan("com.store.spring")
#EnableWebMvc
public class WebConfiguration extends WebMvcConfigurerAdapter {
#Bean
public DataSource dataSource() {
final JndiDataSourceLookup lookup = new JndiDataSourceLookup();
lookup.setResourceRef(true);
DataSource dataSource = lookup.getDataSource("jdbc/product_db");
return dataSource;
}
#Bean
public UrlBasedViewResolver resolver() {
UrlBasedViewResolver viewResolver = new UrlBasedViewResolver();
viewResolver.setPrefix("/WEB-INF/views/");
viewResolver.setSuffix(".jsp");
viewResolver.setViewClass(JstlView.class);
return viewResolver;
}
#Override
public void addViewControllers(ViewControllerRegistry registry) {
registry.addViewController("/").setViewName("index");
}
#Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/resource/css/**").addResourceLocations("/css/").setCachePeriod(31556926);
}
#Override
public void configureDefaultServletHandling (DefaultServletHandlerConfigurer configurer) {
configurer.enable();
}
#Override
public void addInterceptors(InterceptorRegistry registry) {
registry.addInterceptor(new HeaderInterceptor());
}
}
This is Web Application Initializer class
#Component
public class WebInitializer implements WebApplicationInitializer {
#Override
public void onStartup(ServletContext servletContext) throws ServletException {
AnnotationConfigWebApplicationContext context = new AnnotationConfigWebApplicationContext();
context.register(WebConfiguration.class);
// Add context.setCongiglocation("/WEB-INF/spring/dispatcher-config.xml");
ServletRegistration.Dynamic registration = servletContext.addServlet("dispatcher", new DispatcherServlet(context));
registration.addMapping("/");
registration.setLoadOnStartup(1);
ContextLoaderListener listener = new ContextLoaderListener(context);
servletContext.addListener(listener);
}
}
This is the controller class
#Controller
public class ProductController {
#Autowired
private ProductService productService;
#RequestMapping("/index")
public String index(Model model) {
List<Product> listProduct = productService.getPrducts();
model.addAttribute("listProduct", listProduct);
return "index";
}
// Request mapping using SQL tag
#RequestMapping("/location")
public String addLocation(Model model) {
List<Product> listProduct = productService.getPrducts();
model.addAttribute("listProduct", listProduct);
return "location";
}
#RequestMapping("/entry")
public String entry() {
return "Entry";
}
#RequestMapping("/aboutUs")
public String aboutUS() {return "AboutUs";}
#RequestMapping("/deal")
public String deal() {
return "Deal";
}
#RequestMapping("/listProduct")
public String listOrganizationService(Model model) {
List<Product> listProduct = productService.getPrducts();
model.addAttribute("listProduct", listProduct);
return "ListOrganizations";
}
}
This is the header interceptor class
public class HeaderInterceptor extends HandlerInterceptorAdapter {
#Override
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler)
throws Exception {
request.setAttribute("title", "We hope you have a scary and fun filled halloween");
String location = request.getParameter("locationName");
if (location != null) {
request.setAttribute("locationName", location);
}
return true;
}
}
This is the method I want to initialize or call on start up. Or at least
some thing close to this
#RequestMapping("/index")
public String index(Model model) {
List<Product> listProduct = productService.getPrducts();
model.addAttribute("listProduct", listProduct);
return "index";
}
I am using index.jsp to call the listProduct to print my data out. Notice that index.jsp is the first jsp that call when the application start. And I want it to ab able to automatic print those data out
<div class="main-container" style="text-align: center">
<c:forEach var="row" items="${listProduct}">
<div class="detail">
<td>ID: <c:out value="${row.id}"></c:out></td>
<br/>
<td>Name: <c:out value="${row.productName}"></c:out></td>
<br/>
<td>Quantity: <c:out value="${row.quantity}"></c:out></td>
<br/>
<td>Price: <c:out value="${row.price}"></c:out></td>
<br/>
<td><div class="few-line"><c:out value="${row.description}"></c:out></div></td>
</div>
</c:forEach>
I hope someone could help me out.
For Example I had this code inside my WebInitializer class, and when I run it I got an error message
#EventListener(ContextRefreshedEvent.class)
public void contextRefreshedEvent(Model model) {
List<Product> productList = productService.getPrducts();
model.addAttribute("productList", productList)
}

Java Spring initialize, call a method on startup
You can annotate a Spring bean's method with #PostConstruct to have Spring call it after it gets constructed. You can also annotate a method with #Autowired to have Spring call it during the construction of that bean. We typically use one of those to call a method on startup, for example to load data from a database into cache.

Thymeleaf Spring configuration

templateResolver.setTemplateMode("HTML5");
return templateResolver;
}
#Override
public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
configurer.enable();
}
}
the problem is somewhere with TemplateResolver class in my methods. Unfortunatelly it can not be found at all. I inspected org.thymeleaf.templateresolver package where I think it should be but it is not there
can anybody advice what is wrong here please

Finally found correct implementation:
public class WebConfig extends WebMvcConfigurerAdapter implements ApplicationContextAware {
private ApplicationContext applicationContext;
public void setApplicationContext(ApplicationContext applicationContext) {
this.applicationContext = applicationContext;
}
#Bean
public ViewResolver viewResolver() {
ThymeleafViewResolver resolver = new ThymeleafViewResolver();
resolver.setTemplateEngine(templateEngine());
resolver.setCharacterEncoding("UTF-8");
return resolver;
}
#Bean
public TemplateEngine templateEngine() {
SpringTemplateEngine engine = new SpringTemplateEngine();
engine.setEnableSpringELCompiler(true);
engine.setTemplateResolver(templateResolver());
return engine;
}
private ITemplateResolver templateResolver() {
SpringResourceTemplateResolver resolver = new SpringResourceTemplateResolver();
resolver.setApplicationContext(applicationContext);
resolver.setPrefix("/WEB-INF/templates/");
resolver.setTemplateMode(TemplateMode.HTML);
return resolver;
}
}

I'm not sure but try to change #ComponentScan("my.package") with #ComponentScan("thyme.leaf.config").

i want to show the welcome.jsp is my initial page in the project but it not coming so any one find the mistakes and help me

This is my welcome.jsp class
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF8">
<title>JSP Page</title>
</head>
<body>
<h1>Welcome To My Project...</h1>
</body>
</html>
it not show the welcome.page as first page whenever i run my project it shows resource not found

You Can Add the following code in the web.xml file.
<welcome-file-list>
<welcome-file>welcome.jsp</welcome-file>
</welcome-file-list>

In addition to previous answer of Sachin Aryal, You can add more number of welcome pages.
<welcome-file-list>
<welcome-file>welcome.jsp</welcome-file>
<welcome-file>firstpage.html</welcome-file>
<welcome-file>first.jsp</welcome-file>
</welcome-file-list>
The first available file will be taken as welcome file

As i can see you are using Javaconfig i.e no xml approach. I will advice you do it like this
1) Create a root config class, i.e
#Configuration
#ComponentScan({ "com.myrootpackage.whatsoever" })
public class RootClass{
}
2) Make the Class you already have i.e LoginApplication config to extend WebMvcConfigurerAdapter, this will enable you to also load resources or any folders that might have any css or js that you might need in the future
Class LoginApplication extends WebMvcConfigurerAdapter {
#Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/resources/**")
.addResourceLocations("/resources/");
//your view resolver bean as you already have above goes here.
}}
3) Now in the webApplicationInitializer class that you already have, take note of the following
#Override
protected Class<?>[] getRootConfigClasses() {
return new Class[] { RootClass.class };
}
#Override
protected Class<?>[] getServletConfigClasses() {
return class[]{LoginApplication.class];
}
lastly make sure when this application is running you should have Locahlhost:yourport and nothing else to be able to see the welcome.jsp page and make sure welcome.jsp page is located in WEB-INF/views. Hope this helps.

Spring 4 with Annotation Tomcat Deployment 404 Error

I am using Spring 4, Servlet 3 API and Tomcat 8 for my project. I have a problem with deployment. I am trying to deploy WAR package in my VPS. I am using Intellij IDEA.

Here is some screenshot about what settings I used.
IDEA WAR Settings
Project Structures
Tomcat Manage Apps Page
And 404 Error
How can I solve this problem?
Here is my catalina log file's output. I changed WAR's ownership from root to tomcat user. But still same problem.

Edit
I changed /opt/tomcat/webapps ownership to tomcat and now I don't get the 404 error. But now I have this.
INFO [http-nio-8080-exec-17] org.apache.catalina.core.ApplicationContext.log No Spring WebApplicationInitializer types detected on classpath

the exception says
org.apache.catalina.startup.ContextConfig.beforeStart Exception fixing docBase for context [/acentecilik] java.io.IOException: Unable to create the directory
and you've already stated that tomcat is under /opt. so I suppose tomcat has not sufficient permission to create (write permission) on its own directory /opt/tomcat.
If you give write permission to the user who launches the tomcat (most probably your own user) then the problem goes away.
sudo chmod -R 0744 /opt/tomcat
