QuerydslPredicateExecutor problem MongoDB-Spring

QuerydslPredicateExecutor problem MongoDB-Spring - java

I want to use MongoDB and QuerydslPredicateExecutor to have custom query. I tried with the code below, but I have problem
org.springframework.beans.factory.UnsatisfiedDependencyException:
Error creating bean with name 'WS': Unsatisfied dependency expressed
through field 'repository'; nested exception is
org.springframework.beans.factory.BeanCreationException: Error
creating bean with name 'lineeRepository': Invocation of init method
failed; nested exception is
org.springframework.beans.BeanInstantiationException: Failed to
instantiate
[org.springframework.data.mongodb.repository.support.QuerydslMongoPredicateExecutor]:
Constructor threw exception; nested exception is
java.lang.IllegalArgumentException: Did not find a query class
it.polito.pedibus.Model.QFermateM for domain class
it.polito.pedibus.Model.FermateM!
I have this model
#Data
#Entity
#Document("linee")
public class FermateM {
#Id
public ObjectId _id;
private String idlinea;
private List<String> fermate;
}
With this Repository
#Repository
public interface lineeRepository extends MongoRepository<FermateM, String> , QuerydslPredicateExecutor<FermateM> {
FermateM findBy_id(ObjectId _id);
#Query( value = "{}", fields = "{idlinea : 1}" )
List<String> getIDlinea();
}
and this code
#Service
#RestController
public class WS {
#Autowired
private lineeRepository repository;
#RequestMapping(value = "lines", method = RequestMethod.GET)
public List<String> getIDlinee() {
return repository.getIDlinea();
}
}
My pom file is this

Can someone help me please?

You need to import the Q class to the repository, since #Query uses it.
You should use querydsl mongodb, add querydsl-mongodb dependency
The code:
Application.java
package com.example.demo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
#SpringBootApplication
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
}
FermateM.java
package com.example.demo;
import lombok.Data;
import org.bson.types.ObjectId;
import org.springframework.data.annotation.Id;
import org.springframework.data.mongodb.core.mapping.Document;
import java.util.List;
#Data
#Document("linee")
public class FermateM {
#Id
public ObjectId _id;
private String idlinea;
private List<String> fermate;
}
repository
package com.example.demo;
import org.bson.types.ObjectId;
import org.springframework.data.mongodb.repository.MongoRepository;
import org.springframework.data.mongodb.repository.Query;
import org.springframework.data.querydsl.QuerydslPredicateExecutor;
import org.springframework.stereotype.Repository;
import com.example.demo.QFermateM;
import java.util.List;
#Repository
public interface lineeRepository extends MongoRepository<FermateM, String>, QuerydslPredicateExecutor<FermateM> {
FermateM findBy_id(ObjectId _id);
#Query( value = "{}", fields = "{idlinea : 1}" )
List<String> getIDlinea();
}
controller:
package com.example.demo;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
import java.util.List;
#Service
#RestController
public class WS {
#Autowired
private lineeRepository repository;
#RequestMapping(value = "lines", method = RequestMethod.GET)
public List<String> getIDlinee() {
return repository.getIDlinea();
}

Error when using #EnableWebFluxSecurity in springboot

Currently I´m trying to integrate JWT Authentication in an existing Spring Boot Webflux Project.
As a template I used this medium article: https://medium.com/#ard333/authentication-and-authorization-using-jwt-on-spring-webflux-29b81f813e78.
If I put the Annotation #EnableWebFluxSecurity inside my WebSecurityConfig the following error occurs:
The bean 'conversionServicePostProcessor', defined in class path resource [org/springframework/security/config/annotation/web/configuration/WebSecurityConfiguration.class], could not be registered. A bean with that name has already
been defined in class path resource [org/springframework/security/config/annotation/web/reactive/WebFluxSecurityConfiguration.class] and overriding is disabled.
Basicaly it´s the same error as in this post Error creating bean named `conversionServicePostProcessor` when using spring-boot-admin-server but the answers didn´t help for me and I can´t comment on answers.
In the previous post two solutions are mentioned that didn´t work for me.
Removing the websocket dependency didn´t help and setting "spring.main.allow-bean-definition-overriding=true" seems to override my own Configuration, because my route /auth/login/guest is still responding 401.
Here is my WebSecurityConfiguration:
package de.thm.arsnova.frag.jetzt.backend.config;
import de.thm.arsnova.frag.jetzt.backend.security.AuthenticationManager;
import de.thm.arsnova.frag.jetzt.backend.security.SecurityContextRepository;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.HttpMethod;
import org.springframework.http.HttpStatus;
import org.springframework.security.config.annotation.method.configuration.EnableReactiveMethodSecurity;
import org.springframework.security.config.annotation.web.reactive.EnableWebFluxSecurity;
import org.springframework.security.config.web.server.ServerHttpSecurity;
import org.springframework.security.web.server.SecurityWebFilterChain;
import reactor.core.publisher.Mono;
#Configuration
#EnableWebFluxSecurity
#EnableReactiveMethodSecurity
public class WebSecurityConfig {
private final AuthenticationManager authenticationManager;
private final SecurityContextRepository securityContextRepository;
#Autowired
public WebSecurityConfig(AuthenticationManager authenticationManager, SecurityContextRepository securityContextRepository) {
this.authenticationManager = authenticationManager;
this.securityContextRepository = securityContextRepository;
}
#Bean
public SecurityWebFilterChain securityWebFilterChain(ServerHttpSecurity http) {
return http
.exceptionHandling()
.authenticationEntryPoint((swe, e) ->
Mono.fromRunnable(() -> swe.getResponse().setStatusCode(HttpStatus.UNAUTHORIZED))
).accessDeniedHandler((swe, e) ->
Mono.fromRunnable(() -> swe.getResponse().setStatusCode(HttpStatus.FORBIDDEN))
).and()
.csrf().disable()
.formLogin().disable()
.httpBasic().disable()
.authenticationManager(authenticationManager)
.securityContextRepository(securityContextRepository)
.authorizeExchange()

}

You can add this in test properties/app properties:
spring.main.web-application-type=reactive
This begins to be required when servlet and webflux are both in classpath. Check here: https://docs.spring.io/spring-boot/docs/2.3.1.RELEASE/reference/html/spring-boot-features.html#boot-features-testing-spring-boot-applications-detecting-web-app-type

Disable springfox with swagger-codegen

I'm using io.swagger.codegen.v3.swagger-codegen-maven-plugin, version 3.0.18 to generate code from openapi 3 yaml. But, when it's generated, it creates a springfox with swagger 2 configuration.
I want to remove springfox, but I don't know how. I thought about write some properties like "springfox.enable=false", but I can't find nothing about it.
I can't use the Spring profiles because the generated SwaggerDocumentationConfig class, it's created in compilation.
My plugin config:
<configuration>
<inputSpec>${swagger-codegen.api.spec}</inputSpec>
<language>spring</language>
<library>spring-boot</library>
<apiPackage>${swagger-codegen.server.api.package}</apiPackage>

<sourceFolder>.</sourceFolder>
<useBeanValidation>true</useBeanValidation>
<performBeanValidation>true</performBeanValidation>
<delegatePattern>true</delegatePattern>
</configOptions>
</configuration>
The class I want to disable.

#Component Scan Not Working with #Component In Spring Boot across jar and war

I am having a common jar file in spring boot application this way,
package com.acc.api;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
#SpringBootApplication
#ComponentScan(basePackages = {"com.acc.api","service"})
public class ApicoreApplication {
public static void main(String[] args) {
ApplicationContext applicationContext = SpringApplication.run(ApicoreApplication.class, args);
for (String name: applicationContext.getBeanDefinitionNames()) {
System.out.println(name);
}
}
}
And components in this are,
package com.acc.api.core.utils;
import java.util.Map;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
#Component
public class AccUtil {
#Autowired

}
where WebServiceEngine is an third party api i cam calling.
And my pom entries are like these,

Can anyone help me in this regard?
Thanks in Advance.

When using Spring Boot the spring-boot-maven-plugin will repackage and restructure the generated jar file. This jar file isn't useable as a dependency in other applications. Instead you need to instruct the spring-boot-maven-plugin to repackage the jar and leave the original artifact (and publish both to your maven repository).
The Spring Boot Reference Guide has a special section on how to do this.
If your jar is only a dependency and not runnable/executable by itself then just remove the spring-boot-maven-plugin and generate a regular jar.

You have imported com.acc.api.core.utils.AccUtil class twice in StatusController class:
import com.acc.api.core.utils.AccUtil;
#Import({AccUtil.class})
remove one of them and try again.

Spring boot only scans for packages/jars that are a dependency.
Either way, compile-time scope, or run-time scope(provided).
So, if you try to scan jars that are not compile time dependend(default scope), e.g. because you integrate on a interface, you are still dependend on it runtime, so the componentscan can find the implementing class to inject.
If you wire e.g. #RestControllers, the application may be in another package/jar then your controllers.
And though you dont have a compile time dependency of the application package to the controllers, you still need to have the jar runt-time loaded. Otherwise, the controller will not be scanned and found run-time.

Could not find main class Spring-Boot application

I am not able to run my Spring-Boot Framework application in intellij. I am using maven and for some reason it does not find my main class. Also in my Spring application class I get an error for SpringApplication.run that says Cannot access org.springframework.core.env.EnvironmentCapable.

Looks like version mismatch with spring core libraries and springboot version, try with compatible version, still if you see issue, remove .m2 folder completely and run again and see, good luck.

Spring boot + MongoDB - localhost show whitelabel error

So I know there's other questions like this one however I see no solution to my problem.
Hopefully one of you can see what I am doing wrong.
When I go to localhost//:8080 I get "whitelabel error...."
My pom.xml looks like this:

and my application class looks like so:
package com.example.mavenproject1;
import org.springframework.boot.*;
import org.springframework.boot.autoconfigure.*;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.stereotype.*;
import org.springframework.web.bind.annotation.*;
/**

#RestController
#EnableAutoConfiguration
#ComponentScan
public class Application {
//Run a function here which dives into the mongoDB and returns the info?
#RequestMapping("/")
String home() {
DBPopulator dbp = new DBPopulator();
dbp.saveNew();
// return dbp.getFil();
return "Hey wassup";
}
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
And the DBPopulator:
package com.example.mavenproject1;
import java.util.Date;
import java.util.List;
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.AnnotationConfigApplicationContext;
import org.springframework.data.mongodb.core.MongoOperations;
import org.springframework.data.mongodb.core.query.Criteria;
import org.springframework.data.mongodb.core.query.Query;
import org.springframework.data.mongodb.core.query.Update;
import org.springframework.context.support.GenericXmlApplicationContext;
/**

public class DBPopulator {
ApplicationContext ctx = new AnnotationConfigApplicationContext(ConnectToDB.class);
MongoOperations mongoOperation = (MongoOperations) ctx.getBean("mongoTemplate");
private int vers = 0;
public void saveNew() {
Fil f = new Fil("fil" + vers + "", new MetaData(new Date(), new Date(), 5));
vers++;
mongoOperation.save(f);
};
public String getFil(){
// query to search user
Query searchQuery = new Query(Criteria.where("filNavn").is("fil1"));
Fil savedF = mongoOperation.findOne(searchQuery, Fil.class);
List<Fil> listFiler = mongoOperation.findAll(Fil.class);
System.out.println("Here is my file: " + savedF);
return "File: " + savedF;
}
}
now my application "works" as in it saves new "Fil" to my mongoDB. I wanted to return them in the "Home" function in the Application class, but so far I can't get anything but "whitelabel error" out...
Thanks in advance!
**Edit
File Structure is as follows.
and the full error from the localhost//:8080 is:
Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Internal Server Error, status=500).
com/mongodb/BulkWriteException

Looks like it is looking for BulkWriteException which is available from 2.12 mongo driver version.
Solution 1
At least upgrade to
<dependency>
<groupId>org.mongodb</groupId>
<artifactId>mongo-java-driver</artifactId>
<version>2.12.0</version>
</dependency>
Solution 2 (better)
Remove
<dependency>
<groupId>org.mongodb</groupId>
<artifactId>mongo-java-driver</artifactId>
<version>2.11.0</version>
</dependency>
and keep
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-mongodb</artifactId>
<version>1.10.6.RELEASE</version>
</dependency>
pulls in the correct dependency which is 2.4.x mongo driver.
Solution 3 (best)
Remove
<dependency>
<groupId>org.mongodb</groupId>
<artifactId>mongo-java-driver</artifactId>
<version>2.11.0</version>
</dependency>
and
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-mongodb</artifactId>
<version>1.10.6.RELEASE</version>
</dependency>
add
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-mongodb</artifactId>
</dependency>
pulls both the compatible spring mongo and mongo dependency which is 2.4.x mongo driver.
