I am building a simple url shortener connected to MongoDB Atlas with a JPA repository, and when I try to save the url data when the request hits the post request, I get the following error: java.lang.NoSuchMethodError: com.mongodb.client.MongoCollection.insertOne(Ljava/lang/Object;)Lcom/mongodb/client/result/InsertOneResult;. According the research, I believe it is a dependency issue but was not able to resolve it.
URL.java:
package com.sideproject.urlshortner.model;
import lombok.Data;
import org.springframework.data.annotation.Id;
import org.springframework.data.mongodb.core.mapping.Document;
#Data
#Document(collection = "url")
public class URL {
#Id
private String id;
String longURL;
String shortenedURL;
public URL(String longURL, String shortenedURL) {
this.longURL = longURL;
this.shortenedURL = shortenedURL;
}
}
URLController.java:
package com.sideproject.urlshortner.controller;
import com.sideproject.urlshortner.repository.URLRepository;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.HttpStatus;
import org.springframework.web.bind.annotation.*;
import com.sideproject.urlshortner.model.URL;
#RestController
#RequestMapping("/index")
public class URLController {
#Autowired
private URLRepository urlRepository;
#RequestMapping(value="/urls/", method=RequestMethod.POST)
public URL postURL(#RequestBody URL url) {
return urlRepository.save(url); // giving the error.
}
}

Any help would be greatly appreciated!
The issue is you are providing boot starter and mongo driver like below.
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-mongodb</artifactId>
</dependency>
<dependency>
<groupId>org.mongodb</groupId>
<artifactId>mongo-java-driver</artifactId>
<version>3.12.6</version>
</dependency>
whereas spring-boot-starter-data-MongoDB has a java driver dependency of 4.0.4. So 2 different versions are colliding. just remove your explicit mongo driver dependency.
<properties>
<project.type>multi</project.type>
<dist.id>spring-data-mongodb</dist.id>
<springdata.commons>2.3.1.RELEASE</springdata.commons>
<mongo>4.0.4</mongo>
<mongo.reactivestreams>${mongo}</mongo.reactivestreams>
<jmh.version>1.19</jmh.version>
</properties>
One of the features of spring-boot-starter-parent is that it manages versions of many common dependencies for you, ensuring that the versions of all the different pieces you're using are compatible. In this case, your explicit version is causing incompatibility between Spring Data MongoDB and the MongoDB driver; simply eliminate the version tags from your dependencies.
(You may be getting a warning about "overriding managed dependency version"; always pay attention to warnings.)

I downloaded a Spring Boot project from Spring Initializr. I am trying to call sayHello() method in DemoApplication.java. Here are my code.

#SpringBootApplication
#RestController
public class DemoApplication {
public static void main(String[] args) {
System.out.println("started");
SpringApplication.run(DemoApplication.class, args);
System.out.println("Success");
}
#GetMapping("/hello")
public String sayHello(#RequestParam(value = "myName", defaultValue = "World") String name) {
return String.format("Hello %s!", name);

When I run on http://localhost:8080/hello it returns error 404 page. It does not call sayHello() method even though I have set the GET mapping. What could be the issue?
The problem is your dependencies, or rather the lack of them.
You included spring-web as a dependency but that isn't enough to launch your web app. You would also need to add spring-webmvc and as you want to use REST (and probably JSON) you would need to add the jackson-databind dependency (and if you want to support dates also the jackson-datatype-jdk8 dependency).
Now you could of course manually figure all this out yourself by trial and error. Or you just include the spring-boot-starter-web which automatically includes (compatible) versions of all of those dependencies (including Embedded Tomcat).
So in short fix your dependencies.
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
</dependencies>
This should be all you need, if you build a WAR instead of JAR you might want to add
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>
This will make tomcat provided and moved out of the lib folder but still your app would be runnable for development (through the main method) and deployable as a war (without tomcat being in the lib directory).
I'm working on a Spring boot tutorial and I'm a bit stuck on this section of the video. The narrator in the video uses the MaxSizeConfig import inside a return statement. Trying out the same line, I'm getting an error saying that MaxSizeConfig can't be resolved to a type. Checking out the docs for hazelcast, the import exists. Could I get some direction in what I'm doing wrong with my code?

Here's the code that's trying to use MaxSizeConfig:
package com.stephen.springweb.productrestapi.config;
import org.springframework.context.annotation.Bean;
import com.hazelcast.config.Config;
import com.hazelcast.config.EvictionPolicy;
import com.hazelcast.config.MapConfig;
import com.hazelcast.config.MaxSizePolicy;
import org.springframework.context.annotation.Configuration;
#Configuration
public class ProductCacheConfig {
#Bean
public Config cacheConfig() {
return new Config()
.setInstanceName("hazel-instance")
.addMapConfig(new MapConfig()
.setName("product-cache")
.setTimeToLiveSeconds(3000)
.setMaxSizeConfig(new MaxSizeConfig(200, MaxSizePolicy.FREE_HEAP_SIZE))
.setEvictionPolicy(EvictionPolicy.LRU)
);
}
}
Thank you.
For version 4, use setEvictionConfig.
https://docs.hazelcast.org/docs/4.0/javadoc/com/hazelcast/config/EvictionConfig.html
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import com.hazelcast.config.Config;
import com.hazelcast.config.EvictionConfig;
import com.hazelcast.config.EvictionPolicy;
import com.hazelcast.config.MapConfig;
import com.hazelcast.config.MaxSizePolicy;
#Configuration
public class ProductCacheConfig {
#Bean
public Config cacheConfig() {
return new Config()
.setInstanceName("hazel-instance")
.addMapConfig(new MapConfig()
.setName("product-cache")
.setTimeToLiveSeconds(3000)
.setEvictionConfig(new EvictionConfig()
.setSize(200)
.setMaxSizePolicy(MaxSizePolicy.FREE_HEAP_SIZE)
.setEvictionPolicy(EvictionPolicy.LRU)
)
);
}
}
Which version of hazelcast are you using? More precisely, which is inherited from Spring. The setMaxSizeConfig method has been removed in later versions of hazelcast, for example 4.2 https://docs.hazelcast.org/docs/4.2/javadoc/com/hazelcast/config/MapConfig.html
But in version 3.6 it was still https://docs.hazelcast.org/docs/3.6/javadoc/com/hazelcast/config/MapConfig.html
The differences between versions 3 and 4 are significant.

public class MyFirstProjectApplication {

When I'm trying to make a build in IntelliJ IDEA I get errors:
java: package org.springframework.security.crypto.bcrypt does not exist
java: cannot find symbol
symbol: class BCryptPasswordEncoder
location: class com.example.test.myfirstproject.MyFirstProjectApplication
I used autocomplete for method BCryptPasswordEncoder, so there shouldn't be a mistake. I also tried to change the place of security dependency in pom.xml file, but it also didn't help.
Thank you for your help!
I've got a fresh Spring Web application from https://start.spring.io/ with a few dependecies.
Whenever I try to access a REST controller path ("api/companies") the server sends a 404 result with the following message:
"The origin server did not find a current representation for the
target resource or is not willing to disclose that one exists.".

This is how the project structure looks like:
The application's entry point is the CompaniesApplication class:
package helium.erp.com.companies;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
#SpringBootApplication
public class CompaniesApplication extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(CompaniesApplication.class, args);
}
}
The REST controller I'm trying to reach is the following:
package helium.erp.com.companies.company;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
#RestController
#RequestMapping("/api/companies")
public class CompanyApi {
#GetMapping(value = "")
public ResponseEntity<String> getAllCompanies() {
return ResponseEntity.ok("all companies");
}
}
I put a single html file at the root in WebContent and is perfectly returned when I send a GET to the "localhost:9091". The project is added as a server resource and here is the server's configuration:
I have changed the project context root from the default "companies" to "/" via the Eclipse project settings > web project settings > context root and changed the path via the server modules settings like so:
What am I doing wrong? Is there some configuration I am missing?
[SOLVED] Fixing the deployment assembly paths in Eclipse resolved the issue.
I am trying to implement Solr into my Java Spring application, however I have troubles with dependencies, since STS cannot find SolrClient and MultiCoreSolrServerFactory. Here is the class that is causing me troubles:

#Resource
private Environment environment;
#Bean
public SolrServer solrServer() {
String solrHost = environment.getRequiredProperty(SOLR_HOST);
SolrServer server = new HttpSolrServer(solrHost);
MulticoreSolrServerFactory factory;
//I was told to use this factory to return a server, but eclipse cannot find it unfortunately.
}
#Bean (name = "EN")
public SolrTemplate solrEn(){
return new SolrTemplate(solrServer());
//The type org.apache.solr.client.solrj.SolrClient cannot be resolved. It is indirectly referenced from required .class files

Check the solrj jar version in dependencies.
Since spring boot is having a dependency of 4.10.4, new version doesnt get override. The old version does not have Cloud classes.
You can manually add
<dependency>
<groupId>org.apache.solr</groupId>
<artifactId>solr-solrj</artifactId>
<version>5.5.1</version>
</dependency>
You will have new version then.
