Spring boot does not automatically create database tables on Mysql - spring

First I already went over some solution on stacks but they did not work. I make a very basic/learning app on spring / mysql, no tables joining for the moment. The problem is tables are not creating on mysql, while everything is working. I copy my code hereunder.
Thanks in advance for the help

The main entry point of your application is in the com.javaenterprise.votingsystem package. This means that component and entity scanning will find classes in com.javaenterprise.votingsystem and any of its sub-packages. Your entities are in the com.javaenterprise.entity which isn't covered by this scanning.
You could solve the problem by renaming your com.javaenterprise.entity package to com.javaenterprise.votingsystem.entity. Alternatively, you can use #EntityScan to specify the packages that you want to be scanned for entities.

Use the following property:
spring.datasource.url=jdbc:mysql://localhost:3306/dbname?useSSL=false
spring.datasource.username=root
spring.datasource.password=root
spring.jpa.properties.hibernate.show_sql=true
spring.jpa.properties.hibernate.use_sql_comments=true
spring.jpa.properties.hibernate.format_sql=true
spring.jpa.hibernate.ddl-auto=update
And Second, Please add a default constructor as well.
So ur entity class will become:
package com.javaenterprise.entity;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;
#Entity
#Table(name = "citizens")
#Data
#AllArgsConstructor
#NoArgsConstructor
public class Citizen {
#Id
#Column(name="id")
private Long id;
#Column(name = "citizen_name")
private String name;
}

Can you try implementing Serializable and add DEFAULT Constructor ?

You can use this in your application.properties file
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.username=root/your username
spring.datasource.password= yourpassword
spring.datasource.url=jdbc:mysql://localhost:3306/kibria
#for mysql dialect
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect
spring.jpa.hibernate.ddl-auto = update
spring.jpa.show-sql = true

Description:
Parameter 0 of method lockProvider in com.guru.mythoughts.MythoughtsApplication required a bean of type 'com.couchbase.client.java.Bucket' that could not be found.
Action:
Consider defining a bean of type 'com.couchbase.client.java.Bucket' in your configuration.
I have given sample code and when I tried to run the application I am getting the above error. I have scheduled a method in controller and it should run for every 5 seconds.
I have followed the above in the given below link
https://gitcode.net/mirrors/lukas-krecan/ShedLock/-/tree/master/providers/couchbase
How can i solve this error?
Autowired the Cluster class and used the cluster to get the bucket details with bean creation in main class which return the bucket object. please see the same code and it is working fine.
#Autowired
Cluster cluster;
#Bean
public Bucket getBucket() {
return cluster.bucket("bucket");
}
}
Another option is to have a Cluster argument to your getBucket() bean method.
#Bean
public Bucket getBucket(Cluster cluster){
return cluster.bucket("myBucket");
}

Rest controller not registerring

I am building an app with JWT security but it keeps ignoring my rest controllers, and not registering the APIs:

Here is my application.yml
...
server:
url: https://localhost:8443
port: 8443
ssl:
enabled: true
key-store: classpath:keystore/my_keystore.p12
key-store-password: mySuperPassword#
key-store-type: pkcs12
key-alias: mykey
Here is my main class :
package org.home.mysecurityapplication;
#SpringBootApplication(scanBasePackages={"org.home.**"})
public class MySecureApplication {
public static void main(String[] args) {
SpringApplication.run(MySecureApplication.class, args);
}
}
Here is my web initializer :
package org.home.mysecurityapplication.configuration;
public class WebInitializer implements WebApplicationInitializer {
#Override
public void onStartup(ServletContext sc) {
AnnotationConfigWebApplicationContext rootContext = new AnnotationConfigWebApplicationContext();
rootContext.setConfigLocations("org.home.**");
rootContext.refresh();
rootContext.setServletContext(sc);
sc.addListener(new ContextLoaderListener(rootContext));
ServletRegistration.Dynamic apiSR = sc.addServlet("api-dispatcher", new DispatcherServlet(rootContext));
apiSR.setLoadOnStartup(1);
apiSR.addMapping("/");
}
}
Here i am evabling mvc :
package org.home.mysecurityapplication.configuration;
#Configuration
#ComponentScan(basePackages={"org.home.**"})
#EnableWebMvc
public class WebConfig implements WebMvcConfigurer {
}
Here is my security configurer adapter:
package org.home.mysecurityapplication.security;
#Configuration
#EnableWebSecurity
#EnableGlobalMethodSecurity(securedEnabled=true, prePostEnabled=true)
public class MyWebSecurityConfigurerAdapter extends WebSecurityConfigurerAdapter {
private final MyAuthenticationProvider myAuthenticationProvider;
private final CredentialsFilter credentialsFilter;
#Autowired
public MyWebSecurityConfigurerAdapter(MyAuthenticationProvider myAuthenticationProvider, CredentialsFilter credentialsFilter) {
this.myAuthenticationProvider = myAuthenticationProvider;
this.credentialsFilter = credentialsFilter;
}
#Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests()
.antMatchers(HttpMethod.POST, "/roles").permitAll() // everyone should access login-api
;
// disable csrf
http.csrf().disable();
// app session is stateless
http.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS);
http.addFilterBefore(credentialsFilter, UsernamePasswordAuthenticationFilter.class);
http.requiresChannel(channel -> channel.anyRequest().requiresSecure());
}
#Override
protected void configure(AuthenticationManagerBuilder auth) {
auth.eraseCredentials(false)
.authenticationProvider(myAuthenticationProvider);
}
}
Here is my controller:
package org.home.mysecurityapplication.security.controller;
#RestController
#RequestMapping(value="")
public class SecurityController {
#Autowired
private SecurityService securityServiceImpl;
private static final Logger logger = LoggerFactory.getLogger(SecurityController.class);
#RequestMapping(value = "/roles", method = RequestMethod.POST, consumes=MediaType.APPLICATION_JSON_VALUE, produces=MediaType.TEXT_PLAIN_VALUE)
#ResponseStatus(HttpStatus.OK)
public #ResponseBody
String generateToken(#RequestBody CredentialsDTO credentials) throws MyRestPreconditionsException {
logger.debug("User "+credentials.getUsername()+" logging in ...");
String token = securityServiceImpl.generateTokenForUser(credentials);
logger.debug("User "+credentials.getUsername()+" log in successfull.");
return token;
}
}
As you can see, rest controller /roles does not register :(

I suspect you are having a problem with the scanned packages.
#SpringBootApplication encapsulates #Configuration, #EnableAutoConfiguration, and #ComponentScan annotations with their default attributes. The default value for #ComponentScan means that all the sub packages on the package the #ComponentScan is used are scanned. That is why it is usually a good practice to include the main class in the base package of the project, so please make sure it is located there.
Having written this, try the following (drop scanBasePackages attribute and #ComponentScan annotation):
#SpringBootApplication
public class MySecureApplication {
public static void main(String[] args) {
SpringApplication.run(MySecureApplication.class, args);
}
}
#Configuration
#EnableWebMvc
public class WebConfig implements WebMvcConfigurer {
}

Why my REST end points are not exposed? though the application runs successfully. Can someone point out my mistake

I am stuck why I can't access the APIs in my Repository.

please help me.Where I committed wrong.
It's because you do not have a ProductController.java class annotated with #RestController. This file is the entrypoint for all product API request and NOT your ProductRepository.
You can do it something like this:
// Controller File
#RestController
#RequestMapping(path = "/products", produces = {APPLICATION_JSON_VALUE, APPLICATION_XML_VALUE, TEXT_PLAIN_VALUE})
#AllArgsConstructor
public class ProductController {
private final ProductService productService;
#GetMapping()
public ResponseEntity<List<ProductResponseModel>> findAll() {
List<ProductResponseModel> response = productService.findAll());
return new ResponseEntity<>(response, OK);
}
}
// Service File
#Service
public class ProductService {
private final ProductRepository productRepository;
public List<ProductResponseModel> findAll() {
return productRepository.findAll();
}
}

No table is being created neither the RestController Url is working

please tell what I am doing wrong, the code is running with no errors but I am getting no tables or the working restcontroller url whatsoever

Create a repository class and call it for example UserEntityRepository like this:
public interface UserEntityRepository extends JpaRepository<UserEntity, Integer> {
}
Now create a service class and call it UserEntityService like this:
public interface PlayerService {
List<UserEntity> findAll();
Player findById(int theId);
void save(UserEntity theUserEntity);
void deleteById(int theId);
}
You don't necessarily need all these methods but these are common used crud methods.
Then you need to create a class that implements your service class for example:
#Service
public class UserEntityServiceImpl implements UserEntityService {
private UserEntityRepository userEntityRepository;
#Autowired
public CompanyBlueprintServiceImpl(UserEntityRepository theUserEntityRepository ) {
userEntityRepository= theUserEntityRepository ;
}
...
#Override
public void save(UserEntity theUserEntity) {
userEntityRepository.save(theUserEntity);
}
}
After doing all this you have to use your UserEntityService in your controller class. So you can call the save() method from your service to save your entity in your db.
#RestController
#RequestMapping("/api")
public class Ucontroller {
private UserEntityService userEntityService;
public Ucontroller(UserEntityService theUserEntityService) {
userEntityService = theUserEntityService;
}
#RequestMapping("/showall")
public UserEntity showall()
{
return new UserEntity("abc",29);
}
#PostMapping("/users")
public UserEntity addUser(#RequestBody UserEntity theUserEntity) {
// just in case an id in JSON was pass ... set id to 0
// this is to force a save of new item ... instead of update
theUserEntity.setUid(0);
userEntityService.save(theUserEntity);
return theCompany;
}
}
What you did is just creating a UserEntity object and returning it in your controller method showAll().
After saving the userEntity you should see the row in your db.
I am sorry to bother but I did a great mistake, the project package wasn't named correctlyenter image description here
you see the default generated package is com.usere.demo, earlier I named the other packages as com.usere.controller/entity which was wrong and we shouldn't do that, I thought it might not be important to post the package name, that said the correct name should be com.usere.demo.[anything you desire], thank you Constantin Beer and BaDr Amer for helping instantly and telling the right convention and workflow but it was a very stupid mistake that I made.

SpringCloud-Finchley.SR2 Eureka register-center page status 404

I imported a springcloud demo , version Finchley.SR2, after starting the application,I couldn't visit Eureka register center page,status 404.
I don't have and controller yet,Only a #SpringBootApplication
Same problem on eclipse and Idea
Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.
Wed Apr 17 10:46:08 CST 2019
There was an unexpected error (type=Not Found, status=404).
No message available
If I use version Finchley.SR1 with dependency jersey-bundle 1.19, everything is normal.
Here is the pom.xml

Here is my application.yml:
server:
port: 8761
eureka:
client:
register-with-eureka: false
fetch-registry: false
Here is my Application class:
#SpringBootApplication
#EnableEurekaServer
public class HubRegisterCenterApplication {
public static void main(String[] args) {
SpringApplication.run(HubRegisterCenterApplication.class, args);
}
}
Problem solved.
use mvn install command,and I found that there is some problems in maven dependency jar file. delete them and re-download,problem solved
Use application.properties file instead of application.yml file.
like
spring.application.name=cart-service
server.port=8082
It worked for me.
