}
HelloWorldInitializer
public class HelloWorldInitializer implements WebApplicationInitializer {
public void onStartup(ServletContext container) throws ServletException {
AnnotationConfigWebApplicationContext ctx = new AnnotationConfigWebApplicationContext();
ctx.register(ApplicationConfig.class);
ctx.setServletContext(container);
ServletRegistration.Dynamic servlet = container.addServlet(
"dispatcher", new DispatcherServlet(ctx));
servlet.setLoadOnStartup(1);
servlet.addMapping("/");
}
}

I solved this problem. I added #WebAppConfiguration annotation to all my tests and everything started working :). Thanks a lot.

You need a ServletContext bean. Use org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer instead of org.springframework.web.WebApplicationInitializer which implements it. Additionally it contains methods for creating WebApplicationContext which is ServletContext. Change your initializer class as following:
public class HelloWorldInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {
#Override
protected Class<?>[] getRootConfigClasses() {
return new Class[]{ApplicationConfig.class};
}
#Override
protected Class<?>[] getServletConfigClasses() {
return null;
}
#Override
protected String[] getServletMappings() {
return new String[]{"/"};
}
}

No default constructor when adding servlet filter in Spring Boot

I read this other posting about how to add a servlet filter in Spring Boot, but I am getting a No Default Constructor error when I try to follow its example of adding an inner WebConfig class within the UiApplication.java class file.
I am trying this because adding ignoring(/api-url to the app's SecurityConfig class caused a message stating the /api-url has an empty filter list. I want to add a servlet filter for /api-url so that its filter list is no longer empty.
The code for the WebConfig inner class is:
#Configuration
public class WebConfig {
#Bean
public FilterRegistrationBean shallowEtagHeaderFilter() {
FilterRegistrationBean registration = new FilterRegistrationBean();
registration.setFilter(new ShallowEtagHeaderFilter());
registration.setDispatcherTypes(EnumSet.allOf(DispatcherType.class));
registration.addUrlPatterns("/api-url");
return registration;
}
}
What specific changes need to be made to the code below to enable the servlet filter to be added to /api-url without throwing the error?
The complete code for the UiApplication.java class is:
#SpringBootApplication
#Controller
public class UiApplication extends WebMvcConfigurerAdapter {
#Configuration
public class WebConfig {
#Bean
public FilterRegistrationBean shallowEtagHeaderFilter() {
FilterRegistrationBean registration = new FilterRegistrationBean();
registration.setFilter(new ShallowEtagHeaderFilter());
registration.setDispatcherTypes(EnumSet.allOf(DispatcherType.class));
registration.addUrlPatterns("/api-url");
return registration;
}
}
public static void main(String[] args) {
SpringApplication.run(UiApplication.class, args);
}
#Bean
public LocaleChangeInterceptor localeChangeInterceptor() {
LocaleChangeInterceptor lci = new LocaleChangeInterceptor();
lci.setParamName("lang");
return lci;
}
#Override
public void addInterceptors(InterceptorRegistry registry) {
registry.addInterceptor(localeChangeInterceptor());
}
#Configuration
#Order(SecurityProperties.ACCESS_OVERRIDE_ORDER)
#EnableWebSecurity
#EnableGlobalMethodSecurity(prePostEnabled = true)
protected static class SecurityConfiguration extends WebSecurityConfigurerAdapter {
#Override
public void configure(WebSecurity webSecurity) throws Exception {
webSecurity.ignoring().antMatchers("/api-url");
}
#Override
protected void configure(HttpSecurity http) throws Exception {
http
.formLogin()
.and()
.httpBasic().and()
.authorizeRequests()
.antMatchers("/").permitAll()
.antMatchers("/secure**").permitAll()
.anyRequest().authenticated();;
}
}
}
And the complete stack trace of the error when I try to launch the Spring Boot jar is:

Make your WebConfig class static:
#Configuration
public static class WebConfig { ... }
Also, do not put all of your configurations in one class, try to put them in separate classes.

No qualifying bean of type [javax.persistence.EntityManagerFactory] is defined issue in Spring MVC test

I want to run simple test in Spring MVC App but getting
Caused by : org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [javax.persistence.EntityManagerFactory] is defined
exception all the time. I have tried to use java configuration to get test done and that is
#Configuration
public class AppTestConfigurer {
#Bean
public UserService getUserService() {
return new UserService();
}
}
and my test class is
#RunWith(SpringJUnit4ClassRunner.class)
#ContextConfiguration(classes = AppTestConfigurer.class, loader = AnnotationConfigContextLoader.class)
#Transactional
public class UserTest {
#Autowired
private UserService userService;
#Test
public void saveUser() {
User user = new User();
final String userName = "Arshad Ali";
final String userEmail ="arshad#domain.com";
final String userpassword ="1234567";
user.setUserName(userName);
user.setUserEmail(userEmail);
user.setUserPassword(userpassword);
userService.savePost(user);
User retrieveUserFromDB = userService.getUserById(user.getUserId());
assertNotNull(retrieveUserFromDB);
assertEquals(userName, retrieveUserFromDB.getUserName());
assertEquals(userEmail, retrieveUserFromDB.getUserEmail());
assertEquals(userpassword, retrieveUserFromDB.getUserPassword());
}
}
UserService is
#Service
public class UserService {
#PersistenceContext
EntityManager em;
#Transactional
public void savePost(User user) {
em.persist(user);
}
public User getUserById(Long userId) {
return em.find(User.class, userId);
}
}
when I run UserTest class as
I get error log as

when i run the app on server it acts normally but unit testing is causing issues mentioned above.
Are there any mistakes in my configuration or some thing else is causing the exception?
UPDATE
I have made changes and imported my RootConfigurer.class which have EntityManager related configurations as
#Configuration
#Import(value = {RootConfigurer.class})
public class AppTestConfigurer {
#Bean
public UserService getUserService() {
return new UserService();
}
}
now there I'm getting

found answer of this at this SO Answer, and set my RootConfigurer as
#Configuration
#EnableWebMvc
#EnableTransactionManagement
#ComponentScan(basePackages = { "com.app.app" },
excludeFilters = { #ComponentScan.Filter(type = FilterType.ANNOTATION, value = Configuration.class) })
public class RootConfigurer {
private Properties jpaProperties;
#Bean
public DriverManagerDataSource dataSource() {
DriverManagerDataSource dataSource = new DriverManagerDataSource();
dataSource.setDriverClassName(driver);
dataSource.setUrl(url);
dataSource.setUsername(user);
dataSource.setPassword(password);
return dataSource;
}
#Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
LocalContainerEntityManagerFactoryBean entityManagerFactory = new LocalContainerEntityManagerFactoryBean();
entityManagerFactory
.setPackagesToScan("com.rhcloud.logicalerror.imtehan.entity");
entityManagerFactory.setDataSource(dataSource());
jpaProperties = new Properties();
jpaProperties.put("hibernate.show_sql", true);
jpaProperties.put("hibernate.hbm2ddl.auto", "create");
entityManagerFactory.setJpaProperties(jpaProperties);
entityManagerFactory
.setPersistenceProvider(new HibernatePersistenceProvider());
return entityManagerFactory;
}
#Bean
public JpaTransactionManager transactionManager() {
JpaTransactionManager transactionManager = new JpaTransactionManager();
transactionManager.setDataSource(dataSource());
return transactionManager;
}
}
still getting
java.lang.IllegalArgumentException: A ServletContext is required to configure default servlet handling

Add the a correct EntityManagerFactory as a bean in AppTestConfigurer

You threw a NullPointerException in the dataSource() method in your ApplicationContext class (line 53 to be exact), but since you didn't include the code for that method, so its hard to help any further.

Spring JUnit Mockito unit test controller Specified class is an interface

I want to write unit test for simply spring controller.
Everything works - controller, views and model is ok, because when i deploy it on my local tomcat it does exactly what i want. But there is one problem. I try to write unit test for it (I use this tutorial:
http://www.petrikainulainen.net/programming/spring-framework/unit-testing-of-spring-mvc-controllers-configuration/ ) and i get many exceptions.
I tried everything and still it doesn't work.
Here is my code: (IndexControllerTest.java)
#RunWith(SpringJUnit4ClassRunner.class)
#ContextConfiguration(classes = {TestContext.class, WebAppContext.class})
public class IndexControllerTest {
private MockMvc mockMvc;
#Autowired
private UserRepository userRepositoryMock;
#Autowired
private WebApplicationContext applicationContext;
#Before
public void setUp(){
Mockito.reset(userRepositoryMock);
mockMvc = MockMvcBuilders.webAppContextSetup(applicationContext).build();
}
#Test
public void testName() throws Exception {
}
}
(WebAppContext.java):
#EnableWebMvc
#Configuration
#ComponentScan("pl.com.tegess.UnitTestForSpringController")
#EnableMongoRepositories("pl.com.tegess.UnitTestForSpringController.repositories")
public class WebAppContext extends WebMvcConfigurerAdapter {
#Override
public void addResourceHandlers(ResourceHandlerRegistry registry){
registry.addResourceHandler("/static/**").addResourceLocations("/static/");
}
#Override
public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer){
configurer.enable();
}
#Bean
public SimpleMappingExceptionResolver exceptionResolver(){
SimpleMappingExceptionResolver exceptionResolver = new SimpleMappingExceptionResolver();
Properties exceptionMappings = new Properties();
exceptionMappings.put("pl.com.tegess.UnitTestForSpringConfiguration.exceptions.ControllerNotFoundException", "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);
return exceptionResolver;
}
#Bean
#Description("Thymeleaf template resolver serving HTML 5")
public ServletContextTemplateResolver templateResolver() {
ServletContextTemplateResolver templateResolver = new ServletContextTemplateResolver();
templateResolver.setPrefix("/WEB-INF/templates/");
templateResolver.setSuffix(".html");
return templateResolver;
}
#Bean
public SpringTemplateEngine templateEngine() {
SpringTemplateEngine templateEngine = new SpringTemplateEngine();
templateEngine.setTemplateResolver(templateResolver());
return templateEngine;
}
#Bean
public ThymeleafViewResolver viewResolver() {
ThymeleafViewResolver viewResolver = new ThymeleafViewResolver();
viewResolver.setTemplateEngine(templateEngine());
return viewResolver;
}
}
And the controller code: (IndexController.java)
#Controller
public class IndexController {
private UserRepository userRepository;
#Autowired
public IndexController(UserRepository userRepository){
this.userRepository = userRepository;
}
#RequestMapping("/")
public String index(Model model){
Random random = new Random();
Integer i = random.nextInt();
this.userRepository.insertUser(new Member(i.toString()));
model.addAttribute("text", "SomeText");
return "index";
}
}
And the most important thing: (my gradle build.gradle)
buildscript {
repositories {
maven { url "http://repo.spring.io/libs-release" }
mavenLocal()
mavenCentral()
}
}
apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'idea'
apply plugin: 'war'
jar {
baseName = 'UnitTestForSpringController'
version = '1.0'
}
repositories {
mavenLocal()
mavenCentral()
maven { url "http://repo.spring.io/libs-release" }
}
dependencies {
compile("org.springframework:spring-webmvc:4.0.6.RELEASE")

}

Process finished with exit code -1
I found that the reason could be that i have providedCompile javaee in my build.gradle and when i run the test it is not available, but i don't know how can i fix it. Thank for any help :)
After i changed this TextContext to right, i still have similar exceptions:

The reason for this is that you have imported the org.springframework.test.context.TestContext interface. My tutorial uses TestContext class (I should have named it a bit better to avoid this).
The source code of the TestContext class looks as follows:
import org.mockito.Mockito;
import org.springframework.context.MessageSource;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.support.ResourceBundleMessageSource;
#Configuration
public class TestContext {
#Bean
public MessageSource messageSource() {
ResourceBundleMessageSource messageSource = new ResourceBundleMessageSource();
messageSource.setBasename("i18n/messages");
messageSource.setUseCodeAsDefaultMessage(true);
return messageSource;
}
#Bean
public TodoService todoService() {
return Mockito.mock(TodoService.class);
}
}
Just add this class to your project and import it instead of the TestContext interface. You might want to rename it thought to avoid this from happening again.
Also, you might want to consider using the standalone configuration because this way you don’t have to configure the required mock objects as beans. The application context based setup becomes painful when you have a lot of mock objects because you have to remember to configure them in your application context configuration class.
If you use standalone configuration, you don’t have to worry about this because you can configure the required mock objects in the test class.

Following #pkainulainen suggestion and also this post, this should fix your issue:
#RunWith(SpringJUnit4ClassRunner.class)
#ContextConfiguration(classes = {WebAppContext.class})
public class IndexControllerTest {
private MockMvc mockMvc;
#Autowired
private UserRepository userRepositoryMock;
#Autowired
private IndexController controller;
#Before
public void setUp(){
Mockito.reset(userRepositoryMock);
controller = new IndexController(userRepositoryMock);
mockMvc = MockMvcBuilders.standaloneSetup(controller).build();
}
#Test
public void testName() throws Exception {
}
}
You can find more information about standaloneSetup here

I answered something like this some time ago.
Pls have a look at https://stackoverflow.com/a/25840799/1880376
It might help you :)
