A project written in Spring boom fetches data and creates some object. In the same project, a UI was made using webjars.
When I register all the necessary components for the UI properly. then the Rest endpoint paths don't work.
#Configuration
#EnableWebMvc
public class WebMvcConfig implements WebMvcConfigurer {
#Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry
.addResourceHandler("/webjars/**")
.addResourceLocations("/webjars/");
registry.addResourceHandler("/img/**")
.addResourceLocations("classpath:/static/img/");
registry.addResourceHandler("/css/**")
.addResourceLocations("classpath:/static/css/");
registry.addResourceHandler("/js/**")
.addResourceLocations("classpath:/static/js/");
}
}

I try to use actuator endpoints in spring boot. The application runs smoothly. My pom file is given below:

Whenever I try to connect /health,/Info or /metrics endpoint by typing http://localhost:8080/health, the HTTP request transfers to http://localhost:8080/showMyLoginPage. I cannot reach endpoint. How can I solve this? Thanks in advance.
Edit -1
Mr. Fatih demands me to observe the result "http://localhost:8080/actuator" and this picture reveals: the picture
Here is the console output of the application:
https://drive.google.com/file/d/1zYP1qe-Ohbcan93ZO6rqjxX9LqlGiIIg/view?usp=sharing
Edit-2
The problem is partly solved. The actuators are available after the login of the application. But the problem is, after the login page, the homepage appears. All actuators are working, however, whenever I hit http://localhost:8080/actuator/health URL, {"status":"DOWN"} appears at the screen. Here is the console output taken during this operation:
reached urls:
http://localhost:8080/showMyLoginPage

Edit-3
Mr Fatih pointed out some of the changes at the WebSecurityConfiguration. I have changed the code and I am getting this error:
java.lang.IllegalStateException: permitAll only works with either
HttpSecurity.authorizeRequests() or
HttpSecurity.authorizeHttpRequests(). Please define one or the other
but not both.
Here is the change I've made:
/*
* import section have omitted for brevity
*/
#Configuration
#EnableWebSecurity
public class DemoSecurityConfig {
/*
* other codes have omitted for brevity
*/
#Bean
public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
http.authorizeHttpRequests(
(authz) -> authz.antMatchers("/actuator/**").permitAll().anyRequest().authenticated());
http.authorizeRequests(
configurer -> configurer.antMatchers("/**").hasRole("ADMIN").antMatchers("/**").hasRole("USER"))
.formLogin(configurer -> configurer.loginPage("/showMyLoginPage")
.loginProcessingUrl("/authenticateTheUser").permitAll())
.logout(configurer -> configurer.permitAll())
.exceptionHandling(configurer -> configurer.accessDeniedPage("/access-denied"));
return http.build();
}
}
Here is the console output: https://drive.google.com/file/d/1CtjRBHXVRqirZ0Vt_3FEhx_N9oEwyfFZ/view
You are using the spring-security package for application security. So when you want to access your /actuator endpoints, you need to log in first. If you want to access your /actuator endpoints without logging in, you must configure a security configuration. With the following configuration, you can exclude all endpoints starting with /actuator from security.
#EnableWebSecurity
#Configuration
public class WebSecurityConfiguration extends WebSecurityConfigurerAdapter {
#Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests().antMatchers("/actuator/**").permitAll().anyRequest().authenticated();
}
}
Since WebSecurityConfigurerAdapter has been deprecated, you can do this as well.
#Configuration
public class SecurityConfiguration {
#Bean
public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
http
.authorizeHttpRequests(autz -> autz
.mvcMatchers("/actuator/**").permitAll()
.anyRequest().authenticated()
);
return http.build();
}
}
** is a wildcard definition and allows you to access this endpoint without logging in, regardless of what comes after the actuator part.
Please Consider using a version for your dependency as far as i remember 1.9.5 RELEASE or 1.9.5 might help in this context , i had the same issue a year ago.
I have a problem with my Spring Boot Soap Server, im using Spring WS, i have to return my files in attachments, i return a Datahandler to the listtype created by Jaxb, but i see in the response in soap ui, attachments 0, and return me the files in base64.
I dont know how to do this.
Can you help me.
Thanks so much.
My Configuration Bean is:
#Bean
public ServletRegistrationBean messageDispatcherServlet(ApplicationContext applicationContext) {
MessageDispatcherServlet servlet = new MessageDispatcherServlet();
servlet.setApplicationContext(applicationContext);
servlet.setTransformWsdlLocations(true);
return new ServletRegistrationBean(servlet, "/ws/services/*");
}
#Bean(name = "students")
public DefaultWsdl11Definition defaultWsdl11Definition(XsdSchema countriesSchema) {
DefaultWsdl11Definition wsdl11Definition = new DefaultWsdl11Definition();
wsdl11Definition.setPortTypeName("StudentPort");
wsdl11Definition.setLocationUri("/ws/services/test");
wsdl11Definition.setTargetNamespace("http://www.example.org/demo/");
wsdl11Definition.setSchema(countriesSchema);
Properties props = new Properties();
props.put("getDemo", "http://www.example.org/demo/getDemoRequest");
wsdl11Definition.setSoapActions(props);
return wsdl11Definition;
}
#Bean
public XsdSchema countriesSchema() {
return new SimpleXsdSchema(new ClassPathResource("/it/xsd/demo.xsd"));
}
My endpoint have only these annotations:
#PayloadRoot(namespace = NAMESPACE_URI, localPart = "getDemoRequest")
#ResponsePayload
In my demo.xsd, i setted the fileType in
<element name="fileType" type="base64Binary" maxOccurs="unbounded" xmime:expectedContentTypes="application/octet-stream">
I havent xml configuration for now, i would like dont use any xml if it is not necessary in perfect style of Spring Boot.
Thanks so much.

The problem is that the DefaultMethodEndpointAdapter bean adds our MTOM-enabled JAXB marshaller/unmarshaller to the END of the handlers' list. The trick is to override the DefaultMethodEndpointAdapter bean and put them FIRST. This way you don't even need to override the addArgumentResolvers().
The following is Kotlin but should be easy enough to convert to plain Java.
#Bean
override fun defaultMethodEndpointAdapter() = object: DefaultMethodEndpointAdapter() {
override fun initDefaultStrategies() {
super.initDefaultStrategies()
methodArgumentResolvers.add(0, methodProcessor()) // needs to be FIRST in list
methodReturnValueHandlers.add(0, methodProcessor()) // needs to be FIRST in list
}
}
You also need to make sure the relevant #RequestPayload and return params are JAXBELement<...>
Running Spring boot reactive application based off of 2.0.0.RC1. It works by itself with a netty embedded container just fine.
Switching it to a servlet, sorting out the dependencies - exclusions, provisions, weblogic.xml instructions etc, then deploying to WebLogic 12c (12.1.3) container will start the application successfully. However when trying to access the rest url, handled by a single controller, WebLogic throws NPE. It never reaches Spring controller.

I will paste the excerpts of all relevant sources below. First boot app:
#SpringBootApplication
#Configuration
//#EnableAutoConfiguration
//#ComponentScan(basePackages = {"ca.corp.uservice", "ca.corp.uservice.filecache"})
//#ImportResource({"/WEB-INF/ws-dispatcher-servlet.xml"})
//#EnableWebSecurity
public class FileCacheBootApp extends SpringBootServletInitializer implements WebApplicationInitializer {
public static void main(String[] args) {
SpringApplication.run(FileCacheBootApp.class, args);
}
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(FileCacheBootApp.class);
}
...
}
Next the controller:
#RestController
#RequestMapping("/filecache")
public class FileCacheController implements FileCacheApi {
#Autowired
private FileCacheRepository repo;
// -------------- GET ---------------
#GetMapping(value = "{token}")
#Override public Mono<FileCacheable> get(#PathVariable("token") String token) {
return repo.findByToken(token).map(f -> load(f));
}
#GetMapping(value = "app")
#Override public Mono<FileCacheable> get(#RequestParam Long appid, #RequestParam String type, #RequestParam Integer langcode) {
return repo.findByUnique(appid, type, langcode).map(f -> load(f));
}
#GetMapping(value = "zip")
#Override public Mono<FileCacheable> get(#RequestParam String name, #RequestParam Integer langcode) {
return repo.findByNameAndLang(name, langcode);
}
...
}
And finally pom, spring fmw and servlet. Needed to do some jumps here to get it to run w/o conflicts in WebLogic container.

I am trying to be as specific as possible w/o being an info overkill. If you'd like to know more details though... be glad to provide.
Any info or a pointer on the source of the NPE is appreciated.
Solved it. This bit was confusing... I added a dependency for the boot-web back in:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
<version>${spring-boot-version}</version>
<exclusions>
<exclusion>
<groupId>org.hibernate.validator</groupId>
<artifactId>hibernate-validator</artifactId>
</exclusion>
</exclusions>
</dependency>
and then everything started responding. Which kind of makes sense except for the fact that you can't have that dependency if you run WebFlux boot stand alone.
It's a bit unclear as to why standalone (embedded container) cannot have web dependency, and external container must have it. But it works now.
I am starting with SpringBoot, looks great, but I have some questions that I can't understand or find explained in the docs.
I created a new project with the Web, JPA, Security and MySQL dependencies. When my project is created, I go to create a #Controller class. Spring don't find #RequestMapping or ModelAndView classes.
I guessed that use the Web module of SpringBoot will add all the necessary dependencies to use SpringMVC (I read some examples and none add extra dependencies) and all work great with MVC.

Other example, is the WebMvcConfigurerAdapter (from spring-mcv) class that I can't resolve:
org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
This class is from, but I don't see Springboot include this dependy:
org.springframework
spring-webmvc
Maybe I am wrong and read some post that center all the info in Spring Boot, but don't show manual config in the poms.
WebApplication class (Auto Generated):
#SpringBootApplication
public class WebApplication {
public static void main(String[] args) {
SpringApplication.run(WebApplication.class, args);
}
}
ServletInitializer.java class (Auto generated)
public class ServletInitializer extends SpringBootServletInitializer {
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(WebApplication.class);
}
}
Looks like my maven local repository is corrupted.
I was using these libraries in other projects and all works fine. Sorry for the time wasted. Anyway, I let the response for some users with similar problems.
I'm not sure the best way to word this issue, because I have no idea why this happens.
When I start up my Spring Boot application without the spring-integration-core jar, my app starts up fine. The second I add the spring-boot-starter-integration or any spring-integration-core library to my Maven pom file the servlet context is always null on my DelegatingWebMvcConfiguration class and I get the following error:
java.lang.IllegalArgumentException: A ServletContext is required to configure default servlet handling
After doing some debugging, I see the DelegatingWebMvcConfiguration class initialized before the EmbeddedWebApplicationContext sets the servlet context for my application, which makes sense why the servlet context is null for my DelegatingWebMvcConfiguration and set for all the other classes initialized with postProcessBeforeInitialization in ServletContextAwareProcessor. Simply removing the Spring Integration dependency fixes the issue, but I'd like to use Spring Integration in my Boot application.
My question is what would cause the DelegatingWebMvcConfiguration to be created before the EmbeddedWebApplicationContext can call prepareEmbeddedWebApplicationContext method.

#PropertySource(value = "file:../application.properties",
ignoreResourceNotFound = true)
public class ApplicationInitializer extends SpringBootServletInitializer

Update: After trying many different things, I found out after disabling my SchedulingConfigurer my app now starts. Here is my SchedulingConfigurer
#Configuration
#EnableScheduling
#EnableConfigurationProperties(SchedulingProperties.class)
public class SchedulingConfig implements SchedulingConfigurer {
//Inject Runnables and properties
#Override
public void configureTasks(ScheduledTaskRegistrar taskRegistrar) {
taskRegistrar.setScheduler(taskScheduler());
// call taskRegistrar.addFixedRateTask with runnable and property rate value
}
#Bean(destroyMethod = "shutdown")
public Executor taskScheduler() {
ThreadPoolTaskScheduler taskScheduler = new ThreadPoolTaskScheduler();
taskScheduler.setPoolSize(Runtime.getRuntime().availableProcessors());
return taskScheduler;
}
}
