I'm new to spring boot and i'm very much interested to learn this technology. Here is the issue, I got one configuration file with #configuration tag. so i can't run the application when i try to add #enablemvc annotation or if i add new file with #enablemvc annoation in the spring boot application. i really appreciate if some one can help me with thisss.

In general, the #EnableWebMvc should not be used in Spring boot applications. I quote an article by Boz Hogan:
It turns out that Spring Boot doesn’t mix well with the standard Spring MVC #EnableWebMvc. What happens when you add the annotation is that Spring Boot's autoconfiguration is disabled.
The bad part (that wasted me a few hours) is that in no guide you can find that explicitly stated. (...)
Here's a quote from the Spring Boot documentation:
If you want to keep Spring Boot MVC features and you want to add additional MVC configuration (interceptors, formatters, view controllers, and other features), you can add your own #Configuration class of type WebMvcConfigurer but without #EnableWebMvc. (...)
If you want to take complete control of Spring MVC, you can add your own #Configuration annotated with #EnableWebMvc.
So, to use #EnableWebMvc in a Spring Boot app, you need to take complete control of Spring MVC—I read that as you need to be a Spring wiz.
We had a problem with a Spring boot 1.5.9 application that had a dependency to a shared lib that contained a class annotated with #EnableWebMvc. Removing the annotation solved the problem.
It seems the issue is caused by mixing two different kind of initializers i.e WebApplicationInitializer and ApplicationContextInitializer.
Both WebApplicationInitializer and ApplicationContextInitializer serve fairly different purposes.
The WebApplicationInitializer is used by a Servlet Container at startup of the web application and provides a way for programmatic creating a web application(replacement for a web.xml file),
ApplicationContextInitializer provides a hook to configure the Spring application context before it gets fully created.
For a non spring boot application/normal spring mvc app it is programmatic configuration of web.xml. like you have done in your code in WebAppInitializer.java
public class WebAppInitializer implements WebApplicationInitializer {
public void onStartup(ServletContext servletContext) throws
ServletException {
AnnotationConfigWebApplicationContext ctx = new AnnotationConfigWebApplicationContext();
ctx.register(AppConfig.class);
ctx.setServletContext(servletContext);
Dynamic dynamic = servletContext.addServlet("dispatcher", new
DispatcherServlet(ctx));
dynamic.addMapping("/");
dynamic.setLoadOnStartup(1);
}
}
ApplicationContextInitializer is essentially code that gets executed before the Spring application context gets completely created. A good use case for using an ApplicationContextInitializer would be to set a Spring environment profile programmatically, along these lines.
For Spring-Boot based application then registering an ApplicationContextInitializer could be done like below:
#Configuration
#EnableAutoConfiguration
#ComponentScan
public class SampleWebApplication {
public static void main(String[] args) {
new SpringApplicationBuilder(SampleWebApplication.class)
.initializers(new DemoApplicationContextInitializer())
.run(args);
}
}
public class DemoApplicationContextInitializer implements ApplicationContextInitializer<ConfigurableApplicationContext> {
#Override
public void initialize(ConfigurableApplicationContext ac) {
ConfigurableEnvironment appEnvironment = ac.getEnvironment();
appEnvironment.addActiveProfile("demo");
}
}

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[]{"/"};
}
}

I have tried specifying qualifiers, bean names.. still getting errors. Can anyone suggest what I should do to resolve this. I need both the inbound and outbound connections since the application will consume and publish
resolved by adding #Primary to inbound Connection factory
Check this question Spring Boot multiple JMS connections that can help you. If in your case are using a mix of Spring XML and annotations to make a connection factory, maybe you can have problems with SpringBoot, in this case thy disable autostart of spring-boot-jms with this in your application:
#SpringBootApplication(exclude = {JmsAutoConfiguration.class})
this was my case.

I also tried using the below resource. But, I am quite not understanding how to use the #Bean to access the properties across the application
https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-external-config.html
You can refer to two ways:
a) Using property injection, for example:
#Configuration
#EnableTransactionManagement
#ComponentScan({ "com.javabycode.springmvc.configuration" })
#PropertySource(value = { "classpath:jdbc.properties" })
public class MyHibernateConfig {
#Autowired
private Environment environment;
#Bean
public DataSource dataSource() {
DriverManagerDataSource dataSource = new DriverManagerDataSource();
dataSource.setDriverClassName(environment.getRequiredProperty("jdbc.driverClassName"));
dataSource.setUrl(environment.getRequiredProperty("jdbc.url"));
dataSource.setUsername(environment.getRequiredProperty("jdbc.username"));
dataSource.setPassword(environment.getRequiredProperty("jdbc.password"));
return dataSource;
}
}
Found this from the post
b) Using Spring Boot Profile, for example:
This is quite hard to give you sample code here. Check out the post Spring Boot Profiles YAML Properties example
Hope this help!
The constructor of your object is called before the injection happens.
Calling the constructor will initialize your variables like filePath but at this point, env is still not injected and is null.
You may consider having some method like the following, when calling an instance method you are guaranteed that all injections have been completed already :
String getFilePath(){
return env.getProperty("file.path");
}
I would simply take advantage of property injection:
#Value("${file.path}")
private String filePath;
once the file containing that value is registered using the #PropertySource.
I'm trying to setup a spring boot app with an embedded jetty server. This server shall run a small webapp. However, when starting I get the following exception, just after the war file has been loaded.

Any suggestions? Thanks!

I think you need to reuse the handler from the Server:
return new JettyServerCustomizer() {
#Override
public void customize(Server server) {
String jetty_home = System.getProperty("jetty.home","..");
WebAppContext webapp = new WebAppContext();
webapp.setContextPath("/");
webapp.setWar(jetty_home+"/webapps/sample.war");
webapp.setHandler(server.getHandler());
server.setHandler(webapp);
}
};
This error occurs due to WebMvc support being enabled. This can occur due to a configuration class containing #EnableWebMvc, but also due to auto configuration. Try excluding the WebMvc auto configuration.
#EnableAutoConfiguration(exclude = {WebMvcAutoConfiguration.class, WebMvcAutoConfiguration.EnableWebMvcConfiguration.class, WebMvcAutoConfiguration.WebMvcAutoConfigurationAdapter.class})
In my case, I needed the WebMvc support, so I obtained access to the #Configuration class which inherited from WebMvcConfigurationSupport and set the servlet context with a Jetty configuration to fix the NPE.
#Bean
public org.eclipse.jetty.webapp.Configuration jettyConfiguration() {
return new AbstractConfiguration() {
#Override
public void configure(WebAppContext context) throws Exception {
// This line fixes the error in my case
config.setServletContext(context.getServletContext());
}
};
}
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 {

}

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 {
}
}
