Having a catchall request mapping in a contoller exclude resources - java

I have a default spring mvc application. In it, I have a controller like so:
#GetMapping("/**")
public String get(Model model) { }
Now this works for all requests, so that's fine, but it also works for static resources like js, img, css files.
How can I exclude these resources? I am using annotations btw..
What I have tried so far:
WebConfig:
#Override
public void addResourceHandlers(final ResourceHandlerRegistry registry) {
super.addResourceHandlers(registry);
registry.addResourceHandler("/images/**").addResourceLocations("/images/");
registry.addResourceHandler("/css/**").addResourceLocations("/WEB-INF/css/");
registry.addResourceHandler("/js/**").addResourceLocations("/js/");
}
#Override
public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
configurer.enable();
}
WebInitializer:
public class WebInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {
#Override
protected Class<?>[] getRootConfigClasses() {
return new Class[]{WebConfig.class};
}
#Override
protected Class<?>[] getServletConfigClasses() {
return new Class[]{WebConfig.class};
}
#Override
protected String[] getServletMappings() {
return new String[]{"/"};
}
But it doesn't work, and the request for a css file will be handled by the controller instead of showing me the static resource.
As I am not using Spring boot, the solutions mentioned in the linked question did not solve this for me.

How to write Sitemesh configuration withouw WEB.XML

When the project was launched, the mesh site worked in web.xml. But now I want to run it without web.xml and i deleted him. I wrote the code it seems to be correct, but you can tell where you made a mistake or did not write correctly.
He doesn't show me sitemesh menu template
package adil.java.schoolmaven.config;
import org.sitemesh.builder.SiteMeshFilterBuilder;
import org.sitemesh.config.ConfigurableSiteMeshFilter;
public class MySiteMeshFilter extends ConfigurableSiteMeshFilter {

Running Spring web from IDE vs from jar file

I am trying to create a simple web application that will use angular in FE and Spring in BE.
Everything works if I run it from my IDE (IntelliJ IDEA 2017.2), but if I start the jar file it cant find the jsp page and shows an Whitelabel Error Page.
Its gradle build and thease are the dependencies
dependencies {
compile('org.springframework.boot:spring-boot-starter-data-rest')
compile('org.springframework.boot:spring-boot-starter-web')
testCompile('org.springframework.boot:spring-boot-starter-test')
compile 'javax.servlet:jstl:1.2'
}
ChartConfiguration.java
#Configuration
#EnableWebMvc
public class ChartConfiguration extends WebMvcConfigurerAdapter{
#Override
public void configureViewResolvers(ViewResolverRegistry registry) {
InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
viewResolver.setViewClass(JstlView.class);
viewResolver.setPrefix("/WEB-INF/views/");
viewResolver.setSuffix(".jsp");
registry.viewResolver(viewResolver);
}
#Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/static/**").addResourceLocations("/static/");
}
#Override
public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
configurer.enable();
}
}
ChartInitializer.java
import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;
import javax.servlet.Filter;
public class ChartInitializer extends
AbstractAnnotationConfigDispatcherServletInitializer {
#Override
protected Class<?>[] getRootConfigClasses() {
return new Class[] { ChartConfiguration.class };
}
#Override
protected Class<?>[] getServletConfigClasses() {
return null;
}
#Override
protected String[] getServletMappings() {
return new String[] { "/" };
}
#Override
protected Filter[] getServletFilters() {
Filter [] singleton = { new CORSFilter() };
return singleton;
}
}
IndexController.java
#Controller
#RequestMapping("/")
public class IndexController {
#RequestMapping(method = RequestMethod.GET)
public String getIndexPage() {
return "ChartManagement";
}
}
And my jsp page contains only a tag, nothing else.
What am I doing wrong, I cant figure it out?
So I made it work but with a little bit different configuration. I have removed
ChartConfiguration.java
ChartInitializer.java
Everything inside main/resources folder
And now I have created a folder in main/resources called templates, and inside it is index.html
Also I have added a new dependency
compile("org.springframework.boot:spring-boot-starter-thymeleaf")
And changed IndexController to
#Controller
#RequestMapping("/")
public class IndexController {
#RequestMapping(method = RequestMethod.GET)
public String getIndexPage() {
return "index";
}
}

how to Migrate AbstractAnnotationConfigDispatcherServletInitializer in Spring boot?

Hi I am new to spring boot currently I am trying to migrate my maven based web application to spring boot.
I was able to migrate all other configuration file except the below mentioned class:- ApplicationInitializer
public class ApplicationInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {
#Override
protected Class<?>[] getRootConfigClasses() {
return new Class[] { Application.class };
}
#Override
protected Class<?>[] getServletConfigClasses() {
return null;
}
#Override
protected String[] getServletMappings() {
return new String[] { "/" };
}
#Override
protected Filter[] getServletFilters() {
Filter [] singleton = { new CORSFilter()};
return singleton;
}
}
I found one reference link similar to this Reference link which does the same work but I am not sure how to do this for my case.
Can anyone help me to figure it out that how to register my filter with dispatcher servlet.
Thanks in advance.
To register your filter with a dispatcher using SpringBootServletInitializer (that's what you refered to) you need to add FilterRegistrationBean. It may look like that:
public class Application extends SpringBootServletInitializer
{
#Override
protected SpringApplicationBuilder configure( SpringApplicationBuilder application )
{
return application.sources( Application.class );
}
#Bean
public FilterRegistrationBean filterRegistrationBean( ServletRegistrationBean servletRegistrationBean )
{
return new FilterRegistrationBean( new CORSFilter(), servletRegistrationBean );
}
public static void main( String[] args )
{
SpringApplication.run( Application.class, args );
}
}
Be aware that above code replaces your ApplicationInitializer.

#RepositoryRestController custom controller with RepositoryRestMvcConfiguration and AbstractAnnotationConfigDispatcherServletInitializer

I am trying to implement custom controller to handle method defined in custom repository to be able to expose resources using this method via REST (according to Implementing custom methods of Spring Data repository and exposing them through REST).
Here is the configuration and other relevant code:
public class ApplicationInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {
#Override
protected Class<?>[] getRootConfigClasses() {
return new Class<?>[] {ApplicationConfig.class};
}
#Override
protected Class<?>[] getServletConfigClasses() {
return new Class<?>[] {RepositoryRestMvcConfiguration.class};
}
#Override
protected String[] getServletMappings() {
return new String[]{"/api/*"};
}
}
ApplicationConfig:
#Configuration
#EnableJpaRepositories
#EnableTransactionManagement
public class ApplicationConfig {
#Bean
public DataSource dataSource() {
// data source settings
}
#Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
// em factory settings
}
#Bean
public PlatformTransactionManager transactionManager() {
// tx mng settings
}
}
ExperimentRepository:
#RepositoryRestResource
public interface ExperimentRepository extends PagingAndSortingRepository<Experiment, Long>,
ExperimentRepositoryCustom {
#RestResource(rel = "byName", path = "byName")
Page<Experiment> findByNameContaining(#Param("name") String name, Pageable pageable);
}
ExperimentRepositoryCustom:
public interface ExperimentRepositoryCustom {
Page<Experiment> findUsingCustomFilter(...);
}
ExperimentRepositoryImpl:
public class ExperimentRepositoryImpl implements ExperimentRepositoryCustom {
#Override
public Page<Experiment> findUsingCustomFilter(...) {
// search for experiment based on given filter
}
}
ExperimentController:
#RepositoryRestController
public class ExperimentController {
#Autowired
private ExperimentRepository experimentRepository;
#RequestMapping(value = "/experiments/search/findByFilter", method= RequestMethod.GET)
#ResponseBody
public ResponseEntity<Experiment> searchUsingFilter(#RequestParam Long id) {
// for test purpose call method from CrudRepository (will be replaced by findUsingCustomFilter(...))
return new ResponseEntity(experimentRepository.findOne(id), HttpStatus.OK);
}
}
Project structure:
basepackage.model.Experiment
basepackage.repository.ExperimentController
basepackage.repository.ExperimentRepository
basepackage.repository.ExperimentRepositoryImpl
basepackage.repository.ExperimentRepositoryCustom
basepackage.ApplicationInitializer
basepackage.ApplicationConfig
All resources exposed by links automatically generated based on used Repositories are accessible with no problem but calling GET method on http://localhost:8080/app/api/experiments/search/findByFilter?id=1 ends with 404 (resources exposed by links automatically generated based on used Repositories work fine). I assume that ExperimentController is not registered in Spring container or I am missing some additional settings regarding controller method. Any suggestions?
Thanks in advance!
You need configuration to load your Controllers. One way to do this is to add a configuration class to load you Controllers and add it to your ApplicationInitializer.
//PLACE THIS IN A PACKAGE WHERE YOUR CONTROLLERS ARE
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Import;
import org.springframework.data.rest.webmvc.config.RepositoryRestMvcConfiguration;
#ComponentScan
#Import(RepositoryRestMvcConfiguration.class)
public class WebConfig {
}
Change you ApplicationInitializer to
import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;
import com.spring.data.rest.test.web.WebConfig;
public class ApplicationInitializer extends
AbstractAnnotationConfigDispatcherServletInitializer {
#Override
protected Class<?>[] getRootConfigClasses() {
return new Class<?>[] { ApplicationConfig.class };
}
#Override
protected Class<?>[] getServletConfigClasses() {
return new Class<?>[] { WebConfig.class };
}
#Override
protected String[] getServletMappings() {
return new String[] { "/api/*" };
}
}

Resource Not Found after Spring 4.1.2 Update

After I update my web application from Spring 4.1.0 to 4.1.2, the resource mapping stop working.
Without any change, each request to any resource is returning "HTTP 404 - NOT FOUND"(.js, .png, etc...).
Then I switch back to Spring 4.1.0, and everything becomes to work again.
This is my application configuration class:
public class MvcConfiguration extends WebMvcConfigurationSupport {
#Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/resources/**").addResourceLocations("/resources/**");
}
}
This question is similar to this: Resource Not Found after Spring 4.1.2 Update when deploy with JRebel 6.0.0
My resources are at:
[project]\WebContent\resources
And this is my servlet initializer:
public class WebInitializer extends AbstractAnnotationConfigDispatcherServletInitializer implements HttpSessionListener {
private static final int MAX_UPLOAD_SIZE = 1 * 1024 * 1024; // 1mb;
#Override
protected Class<?>[] getRootConfigClasses() {
return new Class<?>[] { MvcConfiguration.class };
}
#Override
protected Class<?>[] getServletConfigClasses() {
return null;
}
#Override
protected String[] getServletMappings() {
return new String[] { "/" };
}
#Override
protected Filter[] getServletFilters() {
CharacterEncodingFilter encodingFilter = new CharacterEncodingFilter();
encodingFilter.setEncoding("UTF-8");
encodingFilter.setForceEncoding(true);
return new Filter[] { encodingFilter, new MultipartFilter() };
}
#Override
protected void customizeRegistration(Dynamic registration) {
File uploadDirectory = new File(System.getProperty("java.io.tmpdir"));
MultipartConfigElement multipartConfigElement = new MultipartConfigElement(uploadDirectory.getAbsolutePath(), MAX_UPLOAD_SIZE, MAX_UPLOAD_SIZE * 2, MAX_UPLOAD_SIZE / 2);
registration.setMultipartConfig(multipartConfigElement);
}
Just change your resource handler to the following:
public class MvcConfiguration extends WebMvcConfigurationSupport {
#Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");
}
}
This broke the code for me too when upgrading from Spring 4.1.1, but removing the trailing /** in Spring 4.1.6 fixed this.
