I am trying to run a spring boot application which uses annotation configuration, below is the WebConfig.java file,
#Configuration
#EnableWebMvc
#ComponentScan(basePackages = {"com.kumar.codebuzz"})
public class WebMvcConfiguration extends WebMvcConfigurerAdapter {
#Override
public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
configurer.enable();
}
#Override
public void addInterceptors(InterceptorRegistry registry) {
registry.addInterceptor(new SecurityHandlerInterceptor()).addPathPatterns("/v1/app/*").excludePathPatterns("/v1/generateOTP", "/v1/validateOTP", "/users/signUp");
}
#Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/swaggerui/**")
.addResourceLocations("classpath:/swaggerui/");
registry.addResourceHandler("/webview/**")
.addResourceLocations("classpath:/webview/");
}
#Bean
public ViewResolver configureViewResolver() {
InternalResourceViewResolver viewResolve = new InternalResourceViewResolver();
viewResolve.setPrefix("/WEB-INF/views/");
viewResolve.setSuffix(".jsp");
return viewResolve;
}
}
i am not able to start the application, below is the stack trace,
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'defaultServletHandlerMapping' defined in class path resource [org/springframework/web/servlet/config/annotation/DelegatingWebMvcConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.web.servlet.HandlerMapping]: Factory method 'defaultServletHandlerMapping' threw exception; nested exception is java.lang.IllegalArgumentException: A ServletContext is required to configure default servlet handling
not able to figure out the issue.
Thanks,
This would happen on below cases
1) #ComponentScan is not mentioned - This is not applicable in your case, since you have mentioned it in the WebMvcConfiguration class
2) #Configuration is used some where else in the same project - Check your project and find for #Configuration, if you have used it accidentally remove it.
There is also another way of removing it
Replace the #ComponentScan in your WebMvcConfiguration with the entry given below
#ComponentScan(basePackages = { "com.kumar.codebuzz" }, excludeFilters = { #Filter(type = FilterType.ANNOTATION, value = Configuration.class) })

I want to test a Spring RestController. There is a Web Config in this project with an #Autowired Constructor, which should initialize a ConfigurationPropertie with environment variables from the application-{environment}.yml-file. Since I have implemented this, my Application runs correctly but the WebMvcTest for the Controller is failing with following error:
Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'webConfig': Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.project.onlineDate.shared.entity.OriginAllowedUrisProperties' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {}
Code Part 1: EnvironmentPropertie Class
#Configuration
#Component
#ConfigurationProperties(prefix = "origins")
public class OriginAllowedUrisProperties {
String[] allowedUris;
//Getter and Setter
}
Code Part 2: WebConfig
#Configuration
public class WebConfig implements WebMvcConfigurer {
private final
OriginAllowedUrisProperties originAllowedUrisProperties;
#Autowired
public WebConfig(OriginAllowedUrisProperties originAllowedUrisProperties) {
this.originAllowedUrisProperties = originAllowedUrisProperties;
}
#Override
public void addCorsMappings(CorsRegistry registry) {
registry.addMapping("/**")
.allowedOrigins(
originAllowedUrisProperties.getAllowedUris());
}
}
Code Part 3: WebMvcTest
#ExtendWith(SpringExtension.class)
#WebMvcTest(OnlineDateController.class)
class TestOnlineDateController {
[...]
#MockBean
private OnlineDateService onlineDateService;
#Autowired
private MockMvc mockMvc;
#Test
void testGetOnlineDate() throws Exception {
when(onlineDateService.findOnlineDates().thenReturn(
Collections.singletonList(new OnlineDate()));
mockMvc.perform(
get("/onlineDates")
.accept(MediaType.APPLICATION_JSON))
.andExpect(status().isOk())
.andExpect(JSON_ONLINE_DATE_MATCHER)
.andDo(print());
}
}
Attemps for fix
I tried for example to declare a Context Configuration at Class Level with #ContextConfiguration(classes = {WebConfig.class}) and I´ve tried to exclude the configuration with #Filter declaration. I have also tried a lot with the OriginAllowedUrisProperties.class to load environment variables in another way, but nothing worked. What am I missing? Do you have an Idea? Thanks in advance.
After struggling to this I want to share my Solution. Hopefully this will help others who face the same challenge.After many attempts I have now solved it a bit differently.
My Solution:
I pulled the bean declaration out of the entity and made it directly in the web controller. This information is not needed anywhere else in the project and therefore I can leave all test classes as they are. Here are the code components, which I have changed in contrast to above.
Code Part 1: EnvironmentProperty Class
Removed Spring Annotations
public class OriginAllowedUrisProperties {
String[] allowedUris;
//Getter and Setter
}
Code Part 2: WebConfig
Bind the #ConfigurationProperties on a #Bean method in WebConfig to bind externalized properties to the OriginAllowedUrisProperties
#Configuration
public class WebConfig implements WebMvcConfigurer {
#Bean
#ConfigurationProperties(prefix = "origins")
public OriginAllowedUrisProperties originAllowedUrisProperties() {
return new OriginAllowedUrisProperties();
}
#Override
public void addCorsMappings(CorsRegistry registry) {
registry.addMapping("/**")
.allowedOrigins(originAllowedUrisProperties().getAllowedUris());
}
}
My goal is to register bean (with a custom bean name) programmatically.
#ComponentScan({ "com.test" })
public class AppConfiguration {
//#Bean("test-bean")
#Bean
public Definition definition() {
return () -> Test.class;
}
}
#Named
#Scope("prototype")
public class Test extends DefinitionActor<?> {
....
}
Here, I use Akka and hence I have to go with #Scope("prototype").
I don't want to hard code the bean name to test-bean for some reason.
Hence, I am using the BeanPostProcessor.
#Component
public class BeanDefinitionRegistryPP implements BeanDefinitionRegistryPostProcessor, EnvironmentAware {
private Environment env;
#Override
public void setEnvironment(final Environment environment) {
this.env = environment;
}
#Override
public void postProcessBeanDefinitionRegistry(final BeanDefinitionRegistry registry) throws BeansException {
}
I am getting AKKA error if I go with this way.
Caused by: akka.actor.ActorInitializationException: You cannot create an instance of [com.test.Test] explicitly using the constructor (new). You have to use one of the 'actorOf' factory methods to create a new actor. See the documentation.
at akka.actor.ActorInitializationException$.apply(Actor.scala:181) ~[akka-actor_2.11-2.4.19.jar:na]
The bean post processor work with non-Akka project. Is there any other way to set the bean name programmatically even I use prototype scope.
I am creating a simple CRUD application using spring boot and hibernate with ajax requests from jsp page. i got working this to the controller and after when i extend my Repo class with JpaRepository i am geting no beans found errors.
i have tried to enable entity manager in web config class an then i also get no beans found for entity manager.
This is my controller class
#Controller
public class EmployeeController {
#Autowired
private EmployeeRepo employeeRepo;
#GetMapping("/")
public String employeeForm() {
return "employeeForm";
}
#PostMapping(value = "/saveEmployee", produces = { MediaType.APPLICATION_JSON_VALUE })
#ResponseBody
public boolean saveEmployee(#ModelAttribute #Valid Employee employee, BindingResult result) {
Employee save = employeeRepo.save(employee);
return true;
}
}
this is my custom repository
public interface EmployeeRepo extends JpaRepository<Employee,Integer> {
}
this is my web config class
#Configuration
#EnableWebMvc
#ComponentScan(basePackages = { "com.boraji.tutorial.spring.controller" })
#ComponentScan(basePackages = { "com.boraji.tutorial.spring.repo" })
#EnableJpaRepositories(basePackages = "com.boraji.tutorial.spring.repo", entityManagerFactoryRef = "entityManagerFactory")
public class WebConfig extends WebMvcConfigurerAdapter {
#Bean
public InternalResourceViewResolver resolver() {
InternalResourceViewResolver resolver = new InternalResourceViewResolver();
resolver.setViewClass(JstlView.class);
resolver.setPrefix("/WEB-INF/views/");
resolver.setSuffix(".jsp");
return resolver;
}
#Bean
public HibernateExceptionTranslator hibernateExceptionTranslator(){
return new HibernateExceptionTranslator();
}
#Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/webjars/**").addResourceLocations("classpath:/META-INF/resources/webjars/");
}
}
this is my webapp initializer class
public class MyWebAppInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {
#Override
protected Class<?>[] getRootConfigClasses() {
return new Class[] {};
}
#Override
protected Class<?>[] getServletConfigClasses() {
return new Class[] { WebConfig.class };
}
#Override
protected String[] getServletMappings() {
return new String[] { "/" };
}
}
this is the error
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'employeeController': Unsatisfied dependency expressed through field 'employeeRepo'; nested exception is
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'employeeRepo': Cannot create inner bean '(inner bean)#7dc21c89' of type

Hi i'm new to spring boot and trying implement the security to my rest apis.
i'm using spring boot 2.0.7.release
i have configures my WebSecurityConfig as following
#Configuration
#EnableWebSecurity
#EnableGlobalMethodSecurity(prePostEnabled = true)
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
#Resource(name = "userService")
private UserDetailsService userDetailsService;
#Bean
#Override
public AuthenticationManager authenticationManagerBean() throws Exception {
return super.authenticationManagerBean();
}
#Autowired
public void globalUserDetails(AuthenticationManagerBuilder auth) throws Exception {
auth.userDetailsService(userDetailsService)
.passwordEncoder(encoder());
}
#Bean
public JwtAuthenticationFilter authenticationTokenFilterBean() throws Exception {
return new JwtAuthenticationFilter();
}
#Bean
public PasswordEncoder encoder(){
PasswordEncoder encoder = new CustomPasswordEncoder();
return encoder;
}
....
}
I have add the resource name so that i can point the to custom userDetailsService.
I have tried configuring authenticationManager Bean by came and pointing the bean by Qualifier authenticationManager bean still it the error remains same.
my pom.xml looks like for security
......
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-security</artifactId>
</dependency>
......
and my implemented UserServiceImpl is
#Service(value = "userService")
public class UserServiceImpl implements UserService, UserDetailsService {
#Autowired
private UserDAOService userDao;
#Autowired
private AuthenticationManager authenticationManager;
#Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
User user = userDao.findByUsername(username);
if(user == null){
throw new UsernameNotFoundException("Invalid username or password.");
}
return new org.springframework.security.core.userdetails.User(user.getEmail(), user.getPassword(), getAuthority());
}
#Override
public String login(LoginUser user) {
// valid user if it exits then do the following
authenticationManager.authenticate(
new UsernamePasswordAuthenticationToken(user.getUsername(), user.getPassword()));
//generate the token and do other process.
}
following are the error logs. i have provided only mail errors

In order to help you better, it is better if you indicate which reference you are following to implement JWT mechansim.
Conceptually, this part of the source code is wrong:
#Override
public String login(LoginUser user) {
// valid user if it exits then do the following
authenticationManager.authenticate(
new UsernamePasswordAuthenticationToken(user.getUsername(), user.getPassword()));
//generate the token and do other process.
}
See if the modifications below can help you
1) Consider using Java Config to declare your beans, in a seperate Configuration class
#Configuration
public class ServiceConfig{
#Bean
protected UserDAOService daoService()
{
return new UserDAOServiceImpl();
}
#Bean
protected UserDetailsService userDetailService( UserDAOService dao )
{
return new UserServiceImpl( dao );
}
#Bean
public PasswordEncoder encoder(){
PasswordEncoder encoder = new CustomPasswordEncoder();
return encoder;
}
#Bean
public JwtAuthenticationFilter authenticationTokenFilterBean() throws Exception{ {
return new JwtAuthenticationFilter();
}
}
2) Modification to your WebSecurityConfig
#Configuration
#EnableWebSecurity
#EnableGlobalMethodSecurity(prePostEnabled = true)
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
#Autowired
private UserDetailsService userDetailsService;
#Autowired
private PasswordEncoder passwordEncoder;
#Override
protected void configure( AuthenticationManagerBuilder auth) throws Exception {
auth.userDetailsService( userDetailsService ).passwordEncoder( passwordEncoder );
}
}
I need use a bean inject with #Component #FeignClient(name = "xxx") when my spring boot application initializing, but it always throws exception like this:
20180706 10:18:40,043 WARN [main]
[org.springframework.context.annotation.AnnotationConfigApplicationContext]
Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'feignContract' defined in org.springframework.cloud.netflix.feign.FeignClientsConfiguration: Unsatisfied dependency expressed through method 'feignContract' parameter 0; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'feignConversionService' defined in org.springframework.cloud.netflix.feign.FeignClientsConfiguration: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.format.support.FormattingConversionService]: Factory method 'feignConversionService' threw exception; nested exception is java.lang.StackOverflowError
my feignClient code:
#Component
#FeignClient(name = "domain-account")
public interface IDomainService {
#RequestMapping(value = "/userInfos", method = RequestMethod.GET)
public String getUserInfos(#QueryMap Map<String, Object> condition);
}
ApplicationListenner code:
public class GlobalInit implements ApplicationListener<ContextRefreshedEvent> {
#Override
public void onApplicationEvent(ContextRefreshedEvent contextRefreshedEvent) {
System.out.println("======== GlobalInit ========");
IDomainService domainService = contextRefreshedEvent.getApplicationContext().getBean(IDomainService.class);
System.out.println("*********************" + domainService);
GlobalInitManager.getInstance().doInit();
}
}
It's not entirely clear for me what you try to do with the GlobalInit but the 'standard' way of designing your Feign client in Spring Boot would the following:
#SpringBootApplication
#EnableFeignClients
#EnableHypermediaSupport(type = EnableHypermediaSupport.HypermediaType.HAL)
#EnableCaching
public class MyHelloWorldApplication {
public static void main(String[] args) {
SpringApplication.run(MyHelloWorldApplication.class, args);
}
}
#Component
public class HelloWorldServiceImpl implements HelloWorldService {
#Autowired
private IDomainService iDomainService ;
public void myMethod() {
String userinfo = iDomainService.getUserInfos(...);
}
}
Hopefully this helps.
All the best,
Wim
