How to configure interceptor in Spring boot?

How to configure interceptor in Spring boot? - java

I have a spring boot application. where i am trying to below operation
AuthenticateIntercepter.java
This class is an Interceptor class in which I'mm trying to print the logs
package com.javamongo.java_mongo.configuration;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.slf4j.Logger;
import org.springframework.stereotype.Component;
import org.springframework.web.method.HandlerMethod;
import org.springframework.web.servlet.HandlerInterceptor;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.handler.HandlerInterceptorAdapter;
import com.javamongo.java_mongo.utils.JWTUtil;
#Component
public class AuthenticateIntercepter implements HandlerInterceptor {
Logger log = org.slf4j.LoggerFactory.getLogger(this.getClass());
#Override
public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object object, Exception arg3)
throws Exception {
log.info("Request Completed!");
}
#Override
public void postHandle(HttpServletRequest request, HttpServletResponse response, Object object, ModelAndView model)
throws Exception {
log.info("Method executed");
}
#Override
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler)
throws Exception {
log.info("After request executed");
return true;
}
}
WebMvcConfig.java
This class is used to call the interceptor.
package com.javamongo.java_mongo.configuration;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
#Configuration
public class WebMvcConfig extends WebMvcConfigurerAdapter {
#Autowired
AuthenticateIntercepter intercepter;
#Override
public void addInterceptors(InterceptorRegistry registry) {
registry.addInterceptor(intercepter).addPathPatterns("/**");
}
}
When i am calling a request i am getting below. but it is not an error
2018-11-09 12:24:34.805 INFO 3964 --- [nio-8090-exec-1] o.a.c.c.C.[Tomcat].[localhost].[/] : Initializing Spring FrameworkServlet 'dispatcherServlet'

Basic authentication in Spring Boot

I have added basic authentication in my Rest API. My API is CRUD. I have changed the username and password. When I apply the GET, GET by id parameter and POST, they are working flawlessly but when I call the PUT and DELETE, I get 401 unauthorized. I have checked the username and password for they are correct or no. There is no problem about it. What is the reason about this issue?

public class SwaggerConfig {

here is the rest controller:

logger.debug("Completed getValue() method...");
}
catch(Exception e){
logger.debug("Exception occurs",e);
e.printStackTrace();
System.out.println("Exception occurs");
}
return myResponse;
}
}
here is the application:-
package com.example.demo;

public class DemoApplication extends SpringBootServletInitializer {
public static void main(String[] args) {

}
full code is in github with logs:-
https://github.com/Sourav654/tempProject/tree/master/demo

Without any logs we can only guess, but looking at your Controller I see some weird things. Can you please try the following?
#RestController
#Validated
#RequestMapping("newcall")
public class DemoController {
Logger logger =LoggerFactory.getLogger(DemoController.class);
#PostMapping("/newResp", consumes = "application/json", produces = application/json)
public MyResponse newResp(#RequestBody String myInput) {
MyResponse myResponse = null;
try {
DemoServiceDAO demoServiceDAO = new DemoServiceImpl();
logger.debug("Started getValue() method...");
myResponse=demoServiceDAO.getValue(myInput);
logger.debug("Completed getValue() method...");
}
catch(Exception e){
logger.debug("Exception occurs",e);
e.printStackTrace();
System.out.println("Exception occurs");
}
return myResponse;
}
}

Spring boot - configure context-path

I have configured application.properties‬ as explained here with :
server.servlet.context-path=/test
And in my #RestController I have a simple a simple #RequestMapping:
#RequestMapping(value = "/products", method = RequestMethod.GET)
But still when sending a request to http://localhost:8080/test/products I get tomcat - 404 response.

Running on tomcat 9, if there is more code or config needed please comment below, thank you.

Any request should 'know' how to get to this controller. I would suggest trying this:
#RestController
#RequestMapping("psc")
public class ProductServiceController {
#RequestMapping(value = "products", method = RequestMethod.GET)
public ResponseEntity<Object> getProduct() {
return new ResponseEntity<>(productRepo.values(), HttpStatus.OK);
}
this way you can send a GET request, to the following url:
http://localhost:8080/test/psc/products
add the #RequestMapping annotation to specify the path to this class(controller)
get rid of the "/" on every #RequestMapping path value (just a cosmetic suggestion)

Field required a bean which could not be found in springboot

I am creating a basic spring boot REST API. My project has the following structure:
com.anonreporting.springboot
--- SpringBootAnonReporting.java , config.java
com.anonreporting.springboot.controller -- userController.java
com.anonreporting.springboot.domain -- User.java
com.anonreporting.springboot.service -- UserService.java UserServiceImpl.java
com.anonreporting.springboot.repository -- userRepository.java
SpringBootAnonReporting.java
#SpringBootApplication
public class SpringBootAnonReporting {
public static void main(String[] args) throws ParseException {
ApplicationContext applicationContext = SpringApplication.run(SpringBootAnonReporting.class, args);
for (String name : applicationContext.getBeanDefinitionNames()) {
System.out.println(name);
}
}
}
User.java is a POJO class.
UserController
#Controller
public class UserController {
#Autowired
UserService userService;
#RequestMapping(value="/users",method=RequestMethod.GET)
ResponseEntity<Iterable<User>> listAllUsers()
{
return new ResponseEntity<Iterable<User>>(userService.listAllUsers(),HttpStatus.OK);
}
#RequestMapping(value="/newuser",method=RequestMethod.POST)
ResponseEntity registerUser(User user)
{
userService.saveUser(user);
return new ResponseEntity(HttpStatus.CREATED);
}
#RequestMapping(value="/get",method=RequestMethod.GET)
ResponseEntity<String> tryGet()
{
System.out.println("hihihih");
return new ResponseEntity<String>("HI",HttpStatus.OK);
}
}
UserService:
#Service
public interface UserService {
Iterable<User> listAllUsers();
User getUserById(String id);
User saveUser(User user);
void deleteUser(String id);
}
UserServiceImpl:
#Service
public class UserServiceImpl implements UserService {

}
#Override
public void deleteUser(String id) {
// TODO Auto-generated method stub
userRepository.delete(id);
}
}

On running the code, the following error occurs:
***************************
APPLICATION FAILED TO START

Description:
Field userRepository in com.anonreporting.springboot.user.UserServiceImpl required a bean of type 'com.anonreporting.springboot.user.UserRepository' that could not be found.
Action:
Consider defining a bean of type 'com.anonreporting.springboot.user.UserRepository' in your configuration.
What I have tried:
All other packages are a sub package of com.anonreporting.springboot, so i don't have to use component scan for them (correct me if i am wrong).
I have tried with componentScan as well with no success.
Moving everything in same package does help, but i want to structure it in this way only. I am using areospike with spring boot.
I have tried changing versions of dependencies also.
Any suggestions would be really helpful. Thank you

As far as I see you have not created UserRepository.java. Spring can not Autowire something that does not exist so you can try creating it in a package that is convenient for you. It should look something like this
#Repository
public interface UserRepository extends JpaRepository<User, Long>{}

You need to change annotation in your UserRepository.class from #Component to #Repository as spring-data is scanning for #Repository annotations.

The problem was with pom.xml only. I just replaced my pom with the following and everything worked.
