I have a database.properties with my database details
I'm using Intellij Idea, and i have a connection enabled to my remote host, i can create a hibernate.cfg.xml with all my tables.
My connection is a remote db, not local

database.root = ebspma_gesdocent
database.password =xxxxxx
hibernate.dialect = org.hibernate.dialect.MySQL5Dialect
hibernate.hbm2ddl.auto = update
hibernate.show_sql = true
When i run the project i have the following error

So, this problem is connection problem or config problem??
Thanks

I'm lost...

utf8 charset with Thymeleaf

When using Spring with Thymeleaf all my Cyrillic characters are shown as ????? on pages.
Using
#RequestMapping(value = "/login", method = RequestMethod.GET, produces = "text/html; charset=utf-8")
as it was suggested here: https://stackoverflow.com/a/11866822/1479414 and here: https://stackoverflow.com/a/12023816/1479414 doesn't help.
How to solve this issue?

The answer can be found here:
Property characterEncoding should be explicitly set for templateResolver and ThymeleafViewResolver:
<bean id="templateResolver" class="org.thymeleaf.templateresolver.ServletContextTemplateResolver">
...
<property name="characterEncoding" value="UTF-8"/>
...
</bean>
<bean class="org.thymeleaf.spring4.view.ThymeleafViewResolver">
...
<property name="characterEncoding" value="UTF-8"/>
...
</bean>

working for me. java config
#Configuration
#EnableWebMvc
#ComponentScan(basePackages = "com.projectName.controller")
public class MVCConfig implements WebMvcConfigurer, ApplicationContextAware {
#Autowired
private ApplicationContext applicationContext;
#Override
public void setApplicationContext(ApplicationContext applicationContext) throws
BeansException {
this.applicationContext = applicationContext;
}
#Bean
public ViewResolver viewResolver(){
ThymeleafViewResolver thymeleafViewResolver = new ThymeleafViewResolver();
thymeleafViewResolver.setTemplateEngine(templateEngine());
thymeleafViewResolver.setCharacterEncoding("UTF-8");
return thymeleafViewResolver;
}
#Bean
public TemplateEngine templateEngine(){
SpringTemplateEngine springTemplateEngine = new SpringTemplateEngine();
springTemplateEngine.setEnableSpringELCompiler(true);
springTemplateEngine.setTemplateResolver(templateResolver());
return springTemplateEngine;
}
#Bean
public ITemplateResolver templateResolver(){
SpringResourceTemplateResolver springResourceTemplateResolver = new
SpringResourceTemplateResolver();
springResourceTemplateResolver.setApplicationContext(applicationContext);
springResourceTemplateResolver.setPrefix("/WEB-INF/views/");
springResourceTemplateResolver.setTemplateMode(TemplateMode.HTML);
springResourceTemplateResolver.setSuffix(".html");
springResourceTemplateResolver.setCharacterEncoding("UTF-8");
return springResourceTemplateResolver;
}
#Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry
.addResourceHandler("/resources/**")
.addResourceLocations("/resources/");
}
}

in Config
public class SpringConfig implements WebMvcConfigurer {
private final ApplicationContext applicationContext;
#Autowired
public SpringConfig(ApplicationContext applicationContext) {
this.applicationContext = applicationContext;
}
#Bean
public SpringResourceTemplateResolver templateResolver() {
SpringResourceTemplateResolver templateResolver = new SpringResourceTemplateResolver();
templateResolver.setApplicationContext(applicationContext);
templateResolver.setPrefix("/WEB-INF/views/");
templateResolver.setSuffix(".html");
templateResolver.setCharacterEncoding("UTF-8");
return templateResolver;
}
#Bean
public SpringTemplateEngine templateEngine() {
SpringTemplateEngine templateEngine = new SpringTemplateEngine();
templateEngine.setTemplateResolver(templateResolver());
templateEngine.setEnableSpringELCompiler(true);
return templateEngine;
}
#Override
public void configureViewResolvers(ViewResolverRegistry registry) {
ThymeleafViewResolver resolver = new ThymeleafViewResolver();
resolver.setTemplateEngine(templateEngine());
resolver.setCharacterEncoding("UTF-8");
registry.viewResolver(resolver);
}
}
In ServletInitializer
public class MySpringMvcDispatcherServletInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {
#Override
protected Class<?>[] getRootConfigClasses() {
return null;
}
#Override
protected Class<?>[] getServletConfigClasses() {
return new Class[]{SpringConfig.class};
}
#Override
protected String[] getServletMappings() {
return new String[]{"/"};
}
#Override
protected Filter[] getServletFilters() {
CharacterEncodingFilter filter = new CharacterEncodingFilter();
filter.setEncoding("UTF-8");
filter.setForceEncoding(true);
return new Filter[] { filter };
}
}

If you have added <property name="characterEncoding" value="UTF-8"/> in the bean configuration for view resolver and still text are not shown in correct format then the problem is in the properties/resource_bundle files.
Try encoding UTF-8 or non-English characters with native2ascii tool. (its included in the java_home/bin folder.

In my case, I put below 2 lines in application.properties file
spring.thymeleaf.enabled=true
spring.thymeleaf.encoding=UTF-8
(Korean)Reference: https://blog.thjang.net/33

With Spring WebFlux, I've restricted the view resolver to use text/html; charset=UTF-8 as the only supported content type. I've used a custom WebFluxConfigurer for that (in Kotlin):
class CustomWebFluxConfigurer(
private val viewResolver: ThymeleafReactiveViewResolver
) : WebFluxConfigurer {
override fun configureViewResolvers(registry: ViewResolverRegistry) {
viewResolver.supportedMediaTypes =
listOf(MediaType.parseMediaType("text/html; charset=UTF-8"))
registry.viewResolver(viewResolver)
}
}

I think in thymeleaf html page you are using th:text with html element, th:text it just display normal text,
if you want use special charter with your thymeleaf html page so just need to change for example
th:utext="${yourcontroller_var}"
or
th:utext="#{properties_var}"
For example
<div th:utext="${user.name}"> Test! </div> // for your controller variable
And
<div th:utext="#{message.username}"> UserName! </div> // for your properties variable
Nothing do other configuration for using special character with thymeleaf html page.
Hope you will fix your problem

After add swagger lib, all response content-type changed to application/xml

I'm a rookie for swagger and springMVC. I just tried to integrate swagger into our system last week. Everything seems great till I deploy the new war. I found all response automatically changed to xml format...Can anyone give some direction about where I should investigate? I've tried the following things:
1. Revert the spring config exclude , not working.
2. add configureContentNegotiation configurer.defaultContentType(MediaType.APPLICATION_JSON),
not working.
Any suggestions are welcome! Thank you!

It should work if you explicitly set each controller to "produce" JSON. I'm sure there's a way to do it in the config as well, but I've always thought it was a best practice to set the produces and consumes explicitly.
#RequestMapping(value="/{studentId}/scores/statistics",
produces = {"application/json"},
consumes = {"application/json"},
method = RequestMethod.GET)

No WebApplicationContext found: no ContextLoaderListener registered?, but not every time that start the server

I really need your help to solve this problem... I'm working with Spring-MVC 4.1.6.RELEASE, Spring-Security 4.0.0.RELEASE
I'm having this ERROR just... "sometimes" when I start the server. That's the real problem it just happens sometimes.
java.lang.IllegalStateException: No WebApplicationContext found: no ContextLoaderListener registered?

Then you will say, that's easy you just have to add a ContextLoaderListener but when I do, I get this:
java.lang.IllegalStateException: Cannot initialize context because there is already a root application context present - check whether you have multiple ContextLoader* definitions in your web.xml!
But it is not always... So I guess there is something wrong in the order that the context are being initialized but I don't know how to fix it...
These are my configuration classes:

AnnotationConfigWebApplicationContext rootContext = new AnnotationConfigWebApplicationContext();
rootContext.register(ServerApplicationConfig.class);
servletContext.addListener(new RequestContextListener());
servletContext.addListener(new ContextLoaderListener(rootContext));
FacesServlet facesServlet = new FacesServlet();
ServletRegistration.Dynamic facesServletDynamic = servletContext.addServlet("facesServlet", facesServlet);
facesServletDynamic.addMapping("*.jsf");
facesServletDynamic.setLoadOnStartup(1);
servletContext.addListener(ConfigureListener.class);
//Oauth2Filter
servletContext.addFilter("auth2ClientContextFilter", OAuth2ClientContextFilter.class);
}

GenericApplicationContext cannot be cast to WebApplicationContext : Spring Web Flow

I'm trying to set up Spring Web Flow using only Java annotations in a Spring environment that also uses only Java annotations. However when I attempt to access my flow I get the following exception

I've traced the source of the error to the instantiation of a RequestContext object, which is passed to views in order for them to access the ApplicationContext (among other things). Since Spring is able to invoke my flows I'm lead to believe that this exception is being thrown due to a bad configuration somewhere in my Web Flow files. I've reviewed them many times and can't find anything that seems glaringly obvious. You can find my Web Flow configuration files below:
DispatcherConfig
#Configuration
#ComponentScan(basePackages = "----")
public class DispatcherConfig {
#Autowired
private FlowDefinitionRegistry flowDefinitionRegistry;
#Autowired
private FlowExecutor flowExecutor;
#Autowired
private AnnotationConfigWebApplicationContext appContext;
#Bean
public FlowHandlerAdapter flowHandlerAdapter()
{
FlowHandlerAdapter flowHandlerAdapter = new FlowHandlerAdapter();
flowHandlerAdapter.setFlowExecutor(flowExecutor);
return flowHandlerAdapter;
}
#Bean
public FlowHandlerMapping flowHandlerMapping()
{
FlowHandlerMapping mapping = new FlowHandlerMapping();
mapping.setFlowRegistry(flowDefinitionRegistry);
mapping.setApplicationContext(appContext);
mapping.setOrder(-1);
return mapping;
}
}
WebFlowConfig
#Configuration
public class WebFlowConfig extends AbstractFlowConfiguration {
#Autowired
private List<ViewResolver> viewResolvers;
#Autowired
private ConversionService conversionService;
#Autowired
private AnnotationConfigWebApplicationContext appContext;
#Bean
public FlowDefinitionRegistry flowRegistry()
{
return getFlowDefinitionRegistryBuilder()
.setBasePath("/WEB-INF/flows")
.addFlowLocationPattern("/**/*-flow.xml")
.setFlowBuilderServices(getFlowBuilderServices())
.build();
}
#Bean
public FlowExecutor flowExecutor()
{
return getFlowExecutorBuilder(flowRegistry()).build();
}
public ExpressionParser getExpressionParser()
{
SpelExpressionParser spelExpressionParser = new SpelExpressionParser();
return new WebFlowSpringELExpressionParser(spelExpressionParser);
}
public FlowBuilderServices getFlowBuilderServices()
{
MvcViewFactoryCreator creator = new MvcViewFactoryCreator();
creator.setViewResolvers(viewResolvers);
creator.setApplicationContext(appContext);
creator.setUseSpringBeanBinding(true);
FlowBuilderServices services = new FlowBuilderServices();
services.setViewFactoryCreator(creator);
services.setConversionService(conversionService);
services.setExpressionParser(getExpressionParser());
return services;
}
}
WebMvcConfig
#EnableWebMvc
#Configuration
public class WebMvcConfig extends WebMvcConfigurerAdapter {
#Bean
public UrlBasedViewResolver velocityViewResolver()
{
UrlBasedViewResolver resolver = new VelocityViewResolver();
resolver.setSuffix(".vm");
resolver.setViewClass(VelocityView.class);
return resolver;
}
#Bean
public VelocityConfigurer velocityConfig()
{
VelocityConfigurer velocityConfigurer = new VelocityConfigurer();
velocityConfigurer.setResourceLoaderPath("/templates/views/");
return velocityConfigurer;
}
#Bean
public List<ViewResolver> viewResolvers()
{
List<ViewResolver> resolvers = new ArrayList<>();
resolvers.add(velocityViewResolver());
return resolvers;
}
}
The view technology I'm using is Velocity. Spring Webflow version 2.4.1.RELEASE, Spring version 4.1.2.RELEASE, Java 1.8.0_45, Tomcat 7.0.62.
Any ideas what may be causing this exception?
UPDATE: Fixed
Thanks to Roman for providing the answer. I made my FlowBuilderServices and MvcViewFactoryCreator #Bean and this got rid of the ClassCastException. However, there were still some problems with my configuration. My #Autowired List<ViewResolver> viewResolvers was not being instantiated until after the MvcViewFactoryCreator was. Thus I had to make a method that creates the ViewResolver list for the MvcViewFactoryCreator. I'm looking into ways to get the order of creation correct, but for now this works. Below are the changes I had to make to get the Web Flow functioning properly
WebFlowConfig

return services;
}
}

FlowBuilderServices is meant to be a Spring-managed bean, but in your config it is just a new instance. It likes to be ApplicationContextAware and InitializingBean, but that is gonna work only if managed by Spring.
The solution is simple: put #Bean on getFlowBuilderServices() method. And I think you should also make MvcViewFactoryCreator a separate #Bean and not use its setApplicationContext() manually.
