Spring: java.lang.IllegalStateException: getOutputStream() has already been called for this response

Hi my first problem was that my application had to download a document (doc or pdf), searching on internet i found a solution and i adapted it to my code.
This is method in #Service where i retrieve blob from database
#Override
public boolean downloadCV(long idDocente, HttpServletResponse response) throws SQLException{
Connection con = null;
try{
con = DBCon.establishConnection();
String sql = "SELECT cv,content_type,filename FROM Docenti_pj where id_docente=? ";
PreparedStatement ps = con.prepareStatement(sql);
ps.setLong( 1 , idDocente);
ResultSet rs = ps.executeQuery();
while( rs.next() ) {
Blob blob = rs.getBlob("cv"); //prende il blob del curriculum
String contentType = rs.getString("content_Type");
String fileName = rs.getString("filename");
if(blob!=null){
InputStream inputStream = blob.getBinaryStream();
response.setHeader("Content-Disposition", "inline;filename=\"" +fileName+ "\"");
OutputStream out = response.getOutputStream();
response.setContentType(contentType);
IOUtils.copy(inputStream, out);
out.flush();
out.close();
return true;
}
else
return false;
}
}
catch(Exception e){
System.out.println("errore");
e.printStackTrace();
}
finally{con.close();}
return false;
}
This is method in my controller
#RequestMapping(value="/docente_cv")
public String downloadCurriculum(#RequestParam long idDocente, Model model, HttpServletResponse response){
try{
if(docenteService.downloadCV(idDocente,response))
return "redirect:/docente_profilo?IdDocente="+idDocente+"&cvdownload=true";
else
return "redirect:/docente_profilo?IdDocente="+idDocente+"&cvdownload=false";
}catch(Exception e){
String message = "Eccezione --> "+e.getMessage();
model.addAttribute("message", message);
return "redirect:/listaDocenteTot";
}
}
All is working fine, but i get in log this error everytime i download a document:

There is a better solution to work with document download in spring? I have saved in DB all file information.
Or there is a better way to use this code to avoid this exception?

Solved it!
I just needed to change code in "#Controller"'s class so i do redirect only if document is not found or exception catched.

As Deinum said you can't downalod and redirect
You may use this code:
#RequestMapping(method = { RequestMethod.GET }, value = { "/docente_cv" })
public ResponseEntity<InputStreamResource> downloadCsv(#PathVariable("idForm") String idForm)
{
Connection con = null;
String fileName = "";
try
{
con = DBCon.establishConnection();
String sql = "SELECT cv,content_type,filename FROM Docenti_pj where id_docente=? ";
PreparedStatement ps = con.prepareStatement(sql);
ps.setLong( 1 , idDocente);
ResultSet rs = ps.executeQuery();
while( rs.next() )
{
Blob blob = rs.getBlob("cv"); //prende il blob del curriculum
String contentType = rs.getString("content_Type");
fileName = rs.getString("filename");
if(blob!=null)
{
InputStream inputStream = blob.getBinaryStream();
response.setHeader("Content-Disposition", "inline;filename=\"" +fileName+ "\"");
HttpHeaders respHeaders = new HttpHeaders();
MediaType mediaType = MediaType.parseMediaType(contentType)
respHeaders.setContentType(mediaType);
respHeaders.setContentLength(file.length());
respHeaders.setContentDispositionFormData("attachment", fileName);
InputStreamResource isr = new InputStreamResource(inputStream);
return new ResponseEntity<InputStreamResource>(isr, respHeaders, HttpStatus.OK);
}
else
{
return new ResponseEntity<InputStreamResource>(HttpStatus.NO_CONTENT);
}
}
}
catch (Exception e)
{
String message = "Errore nel download del file "+fileName+"; "+e.getMessage();
logger.error(message, e);
return new ResponseEntity<InputStreamResource>(HttpStatus.INTERNAL_SERVER_ERROR);
}
finally
{
if(con != null)
con.close();
}
}
I hope it's useful

Unable to authentication a user with spring custom filter

I am trying to authenticate a user on login request with username and password comparing from database using jpa but some how the authentication fails and returns 401 error.
The request flow is as follows:
Request from client side:
login: function(data,success, error){
$http.post('auth', data).success(success).error(error);
}
application.yml is configured to accept request for "auth" as
# config context path to "/" by setting an empty string
server:
contextPath:
# JACKSON
spring:
jackson:
serialization:
INDENT_OUTPUT: true
jwt:
header: Authorization
secret: mySecret
expiration: 604800
route:
authentication:
path: auth
refresh: refresh
logging:
level:
org.springframework:
security: DEBUG
Web security:
#Override
protected void configure(HttpSecurity httpSecurity) throws Exception {
httpSecurity
.exceptionHandling().authenticationEntryPoint(unauthorizedHandler).and()
.authorizeRequests()
.antMatchers(HttpMethod.POST, "/registration").permitAll()
.antMatchers("/auth/**").permitAll()
.anyRequest().authenticated();
// Custom JWT based security filter
httpSecurity
.addFilterBefore(authenticationTokenFilterBean(), UsernamePasswordAuthenticationFilter.class);
// disable page caching
httpSecurity.headers().cacheControl();
}
I am not sure how the flow is going through but the request comes to createAuthenticationToken() method in the below class and prints this line System.out.println("Authenticate called in createAuthenticationToken"); but doesn't call the authenticationManager.authenticate() which is right after that even though I am able to print credentials from JwtAuthenticationRequest authenticationRequest bean.
#RestController
public class AuthenticationRestController {
#Value("${jwt.header}")
private String tokenHeader;
#Autowired
private AuthenticationManager authenticationManager;
#Autowired
private JwtTokenUtil jwtTokenUtil;
#Autowired
private UserDetailsService userDetailsService;
#RequestMapping(value = "${jwt.route.authentication.path}", method = RequestMethod.POST)
public ResponseEntity<?> createAuthenticationToken(#RequestBody JwtAuthenticationRequest authenticationRequest, Device device) throws AuthenticationException {
System.out.println("Authenticate called in createAuthenticationToken"); //PRINTS THIS LINE
// THIS IS NOT CALLED
final Authentication authentication = authenticationManager.authenticate(
new UsernamePasswordAuthenticationToken(
authenticationRequest.getUsername(),
authenticationRequest.getPassword()
)
);
System.out.println("authenticationManager.authenticate(JWTAuthRequest) is=" + authentication); //THIS IS NOT PRINTED
SecurityContextHolder.getContext().setAuthentication(authentication);
// Reload password post-security so we can generate token
final UserDetails userDetails = userDetailsService.loadUserByUsername(authenticationRequest.getUsername());
System.out.println("userDetailsService.loadUserByUsername->userDetails is->" + userDetails);
final String token = jwtTokenUtil.generateToken(userDetails, device);
System.out.println("jwtTokenUtil.generateToken(userDetails, device) is->" + token);
// Return the token
return ResponseEntity.ok(new JwtAuthenticationResponse(token));
}
}
From here on it goes to custom entry point and returns 401 error to client. Why isn't it authenticating the user and returning a token even though the credentials are present? What am I doing wrong?
Entry point:
#Component
public class JwtAuthenticationEntryPoint implements AuthenticationEntryPoint, Serializable {
private static final long serialVersionUID = -8970718410437077606L;
#Override
public void commence(HttpServletRequest request,
HttpServletResponse response,
AuthenticationException authException) throws IOException {
System.out.println("ENTRY POINT"); //PRINTS THIS
// This is invoked when user tries to access a secured REST resource without supplying any credentials
// We should just send a 401 Unauthorized response because there is no 'login page' to redirect to
response.sendError(HttpServletResponse.SC_UNAUTHORIZED, "Unauthorized");
}
}
I have got the above code concept from https://github.com/szerhusenBC/jwt-spring-security-demo.git
update
Up on enabling debug logs in application.yml I get this error:

ENTRY POINT

Looking at the source for UsernamePasswordAuthenticationToken,
/**
* This constructor can be safely used by any code that wishes to create a
* <code>UsernamePasswordAuthenticationToken</code>, as the {#link
* #isAuthenticated()} will return <code>false</code>.
*
*/
public UsernamePasswordAuthenticationToken(Object principal, Object credentials) {
super(null);
this.principal = principal;
this.credentials = credentials;
setAuthenticated(false);
}
/**
* This constructor should only be used by <code>AuthenticationManager</code> or <code>AuthenticationProvider</code>
* implementations that are satisfied with producing a trusted (i.e. {#link #isAuthenticated()} = <code>true</code>)
* authentication token.
*
* #param principal
* #param credentials
* #param authorities
*/
public UsernamePasswordAuthenticationToken(Object principal, Object credentials, Collection<? extends GrantedAuthority> authorities) {
super(authorities);
this.principal = principal;
this.credentials = credentials;
super.setAuthenticated(true); // must use super, as we override
}
Your code only seems to be setting the username and password. To authenticate, you need to pass in 3 parameters - username, password and a collection of granted authorities. If you have this, pass it. Else, pass null as a third parameter.
Hope this works for you.

How to properly configure my SpringMVC 4 application to use Thymeleaf?

My application is, currently, on a stage where I can start working on the view layer. Though JSPs are exceptional at speed, I'd like to try using a HTML5 template from wrapbootstrap.com. In this question I asked how to do it, and the idea was to use a templating engine like Thymeleaf.
So I added to my pom.xml the following dependency:
<dependency>
<groupId>org.thymeleaf</groupId>
<artifactId>thymeleaf-spring4</artifactId>
<version>2.1.4.RELEASE</version>
</dependency>
And added the following bean to my configuration class:
#Configuration
#EnableWebMvc
#ComponentScan(basePackages = "b.c.m.h")
public class HConfiguration extends WebMvcConfigurerAdapter {
#Bean
public ViewResolver viewResolver() {
ClassLoaderTemplateResolver templateResolver = new ClassLoaderTemplateResolver();
templateResolver.setTemplateMode("HTML5");
templateResolver.setPrefix("/WEB-INF/html");
templateResolver.setSuffix(".html");
SpringTemplateEngine engine = new SpringTemplateEngine();
engine.setTemplateResolver(templateResolver);
ThymeleafViewResolver viewResolver = new ThymeleafViewResolver();
return viewResolver;
}
(...)
}
There a mapping on my controller defined as:
#RequestMapping(value = { "/", "/home" }, method = RequestMethod.GET)
public String homePage(ModelMap model) {
return "welcome";
}
This mapping says that URLs ending with "/" or "/home" should be handled by the page on WEB-INF/html/welcome.html.
I'm getting a null pointer when I try to access "/".

What am I missing here?

Try to change like following:
#Bean
public ViewResolver viewResolver() {
ServletContextTemplateResolver templateResolver = new ServletContextTemplateResolver();
templateResolver.setTemplateMode("HTML5");
templateResolver.setPrefix("/WEB-INF/html/");
templateResolver.setSuffix(".html");
SpringTemplateEngine engine = new SpringTemplateEngine();
engine.setTemplateResolver(templateResolver);
ThymeleafViewResolver viewResolver = new ThymeleafViewResolver();
viewResolver.setTemplateEngine(engine);
return viewResolver;
}

Oauth2 with Spring Security - UserRedirectRequiredException

I want to implement OAuth2 in my web but I got this error when I try to do a request: /facebook/info
I was follow the official guide and I look the examples but I still doing something is wrong, As the error said A redirect is required to get the users approval and I read somewhere (don't remember) that the redirect url is added by the filter I was thinking that isn't configured right... or the error comes from other place.
Config:
public class WebAppInitializer implements WebApplicationInitializer {
private static final String DISPATCHER_SERVLET_NAME = "dispatcher";
private static final String DISPATCHER_SERVLET_MAPPING = "/";
#Override
public void onStartup(ServletContext container) throws ServletException {
registerProxyFilter(container, "oauth2ClientContextFilter");
...
// Add filters
private void registerProxyFilter(ServletContext servletContext, String name) {
DelegatingFilterProxy filter = new DelegatingFilterProxy(name);
filter.setContextAttribute("org.springframework.web.servlet.FrameworkServlet.CONTEXT.dispatcher");
servletContext.addFilter(name, filter).addMappingForUrlPatterns(null,
false, "/*");
}
}
}
Add security filter:
public class SecurityWebApplicationInitializer extends
AbstractSecurityWebApplicationInitializer {
}
RestTemplate:
#Bean
#Scope(value = "session", proxyMode = ScopedProxyMode.INTERFACES)

I notice what the ExecptionResolver was making the problem, to solve it I exclude a exception.
#Bean
public SimpleMappingExceptionResolver exceptionResolver() {
SimpleMappingExceptionResolver exceptionResolver = new SimpleMappingExceptionResolver();
Properties exceptionMappings = new Properties();
exceptionMappings.put(
"com.test.commons.model.exceptions.NotFound", "error/404");
exceptionMappings.put("java.lang.Exception", "error/error");
exceptionMappings.put("java.lang.RuntimeException", "error/error");
exceptionResolver.setExceptionMappings(exceptionMappings);
Properties statusCodes = new Properties();
statusCodes.put("error/404", "404");
statusCodes.put("error/error", "500");
exceptionResolver.setStatusCodes(statusCodes);
// ADDED TO IGNORE THRE USER_REDIRECT_REQUIRED_EXCEPTION
exceptionResolver
.setExcludedExceptions(UserRedirectRequiredException.class);
return exceptionResolver;
}
I still getting the error, but now is redirected to a facebook page and not to a error page

Weird java.io.NotSerializableException: org.springframework.dao.support.PersistenceExceptionTranslationInterceptor

I have a weird problem with my application. I am using Spring-webflow with Primefaces and i would like to switch to sprind-data-jpa.
Here is my backingBean.
#Component
#Scope("flow")
public class CustomerUI implements Serializable {
#Autowired
private ICustomerService customerService;
private List<Customer> customerList;
private LazyDataModel<Customer> customerLazyDataModel;
public void init() {
customerLazyDataModel = new LazyDataModel<Customer>() {
#Override
public List<Customer> load(int first, int pageSize, String sortField, SortOrder sortOrder, Map<String, Object> filters) {
return customerService.listCustomers(first,pageSize);
}
};
}
public List<Customer> getCustomerList() {
return customerList;
}
public void setCustomerList(List<Customer> customerList) {
this.customerList = customerList;
}
public LazyDataModel<Customer> getCustomerLazyDataModel() {
return customerLazyDataModel;
}
public void setCustomerLazyDataModel(LazyDataModel<Customer> customerLazyDataModel) {
this.customerLazyDataModel = customerLazyDataModel;
}
}
Here is my Service, it is now partially mocked:
#Service
public class CustomerImplementation implements ICustomerService {
#Autowired
private CustomerRepository customerRepository;
#Override
public int getPagesCount(int perPage) {
return 0;
}
#Override
public Customer persist(Customer customer) {
if(customer.getNewAddress() != null && !customer.getNewAddress().equals(""))
{
if(customer.getAddress() != null && customer.getAddress().size() > 0)
{
boolean found = false;
for(Address address : customer.getAddress())
{
if(address.getAddress().equals(customer.getNewAddress()))
{
found = true;
break;
}
}
if(!found)
{
Address address = new Address();
address.setAddress(customer.getNewAddress());
address.setCustomer(customer);
customer.getAddress().add(address);
}
}else{
Address address = new Address();
address.setAddress(customer.getNewAddress());
address.setCustomer(customer);
if(customer.getAddress() == null)
{
customer.setAddress(new LinkedList<Address>());
}
customer.getAddress().add(address);
}
}
return customerRepository.save(customer);
}
#Override
public List<Customer> listCustomers(int page, int limit) {
List<Customer> customers;
customers = customerRepository.findAll();
return customers;
}
#Override
public List<Customer> findCustomersByString(String search) {
search = search.toLowerCase();
return Collections.EMPTY_LIST;
}
#Override
public Customer findCustomerById(int id) {
return customerRepository.findOne(id);
}
#Override
public Customer persistRepo(Customer customer) {
return customerRepository.save(customer);
}
}
