Using #ConfigurationProperties in a #Scheduled annotation by referencing the bean name

Using #ConfigurationProperties in a #Scheduled annotation by referencing the bean name - java

I'm using #ConfigurationProperties to configure the delay of a background task in Spring boot and I'm trying to use this value from a #Scheduled annotation on another component. However, in order to make it work I must use the full name given to the bean by Spring.
The configuration properties class is as follows:
#ConfigurationProperties("some")
class SomeProperties {
private int millis; //the property is some.millis
public int getMillis() {
return millis;
}
public void setMillis(int millis) {
this.millis = millis;
}
}
And I'm using the value as follows in the scheduled method:
#Component
class BackgroundTasks {
#Scheduled(fixedDelayString = "#{#'some-com.example.demo.SomeProperties'.millis}") //this works.
public void sayHello(){
System.out.println("hello");
}
}
Is it possible to reference the value without having to use the full name of the bean? This answer suggests it is possible but I haven't been able to make it work.

Using #Componenton the properties class allows to access the property as "#{#someProperties.persistence.delay}.
More info in the spring boot documentation.

SomePrperties.java
package com.example.demo;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;
#ConfigurationProperties("some")
#Component("someProperties")
public class SomeProperties {
private int millis; // the property is some.millis
public int getMillis() {
return millis;
}
public void setMillis(int millis) {
this.millis = millis;
}
}
BackgroundTasks.java
package com.example.demo;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;
#Component
public class BackgroundTasks {
/**
*
* Approach1: We can inject/access the property some.millis directly in #Value
* fashion even though we have configured it to bind with SomeProperties class
* using #ConfigurationProperties.
*
*
*/
#Scheduled(fixedRateString = "${some.millis}")
public void fromDirectInjection() {
System.out.println("Hi, I'm from DirectInjection method");
}
/**
*
* Approach2: Add #Component on SomeProperties and access the bean bean's
* property millis like below using Spring Expression language
*
*
*/
#Scheduled(fixedRateString = "#{#someProperties.millis}")
public void fromConfigurationProperty() {
System.out.println("Hi, I'm from ConfigurationProperty method");
}
}

Following should work fine assuming bean is created with someProperties by default and name is not overridden.
#Scheduled(fixedDelayString = "#{#someProperties.getMillis()}")

from Spring documentation:
When the #ConfigurationProperties bean is registered using configuration property scanning or via #EnableConfigurationProperties, the bean has a conventional name: -, where is the environment key prefix specified in the #ConfigurationProperties annotation and is the fully qualified name of the bean. If the annotation does not provide any prefix, only the fully qualified name of the bean is used.
The bean name in the example above is com.example.app-com.example.app.SomeProperties.
So the answer boils to:
if you use JavaBean style properties you can register bean with #Component or #Bean. Then you can use just the bean name in SPEL expression
if you use #ConstructorBinding to have immutable properties then you have to use fully qualified bean name with the enviroment key prefix like this:
#Scheduled(fixedRateString = "#{#'other-com.example.demo.OtherProperties'.millis}")
Here is sample project - https://github.com/marksutic/scheduler_fixedratestring, forked from Arun Sai

I faced same issue when i was beginner in Spring Framework. If put #Service annotaion on interface then service interface become useless so, Remove #Service annotation from WorkerService and put this annotation in WorkerServiceImpl.

Why can't Postman find my Spring REST API?

I created a very basic Spring Boot project with REST APIs. I tried connecting it to my Angular app but it was getting some CORS security error so I switched to Postman. I'm trying to test it using Postman but I keep receiving a 404 not found error on Postman. Why am I not able to connect to my backend and post to tester function?
controller
package controllers;
#RestController
public class Handler {
#PostMapping("/tester/{id}")
public String tester(#PathVariable(value="id")long userid ){
System.out.println("in tester");
System.out.println(userid);
return "succeeded test";
}
}
main
package halloween.contest;
#SpringBootApplication(exclude = {DataSourceAutoConfiguration.class,
SecurityAutoConfiguration.class})
public class ContestApplication {
public static void main(String[] args) {
SpringApplication.run(ContestApplication.class, args);
}
}

Postman

Answering my own question now that I figured it out. It wasn't apparent based on the code I provided but I'll leave my post for future help (wording helps).
the problem was visibility of packages. I had my controller class in a different package from the main class.

To fix the CORS issue, next to #PostMapping("/tester/{id}") add #CrossOrigin(origins = "http://localhost:<port>") where port is the port from which your Angular app is running.
In your target URL, make sure you've included the default Spring Boot port of 8080, e.g. http://localhost:8080/tester/123 and obviously, please double check that you're doing a POST and not a GET.

got a similar problem..then added the below annotations on top of springbootappication where main() exists, then it's working fine for me.
#EnableWebMvc
#ComponentScan("com.*.*")
Also in postman make the below changes...
Disable/uncheck File --> Proxy --> "Use the system proxy"
Disable/uncheck File --> General --> "SSL Certificate Verification"

Java controller always return a 404 no matter what I do

I was following an example from the spring boot documentation and the java controller always returns a 404 for some reason
This is what I tried
package com.example.accessingdatamysql;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
#Controller // This means that this class is a Controller
#RequestMapping(path="/demo") // This means URL's start with /demo (after Application path)
public class MainController {
#Autowired // This means to get the bean called userRepository
// Which is auto-generated by Spring, we will use it to handle the data
private UserRepository userRepository;
#PostMapping(path="/add") // Map ONLY POST Requests
public #ResponseBody String addNewUser (#RequestParam String name
, #RequestParam String email) {
// #ResponseBody means the returned String is the response, not a view name
// #RequestParam means it is a parameter from the GET or POST request
User n = new User();
n.setName(name);
n.setEmail(email);
userRepository.save(n);
return "Saved";
}
#GetMapping(path="/all")
public #ResponseBody Iterable<User> getAllUsers() {
// This returns a JSON or XML with the users
return userRepository.findAll();
}
}
which is the example given by spring boot here https://spring.io/guides/gs/accessing-data-mysql/
Then I also tried
#RestController
#RequestMapping("/demo")
public class GreetingClass {
#GetMapping("/greeting")
public String getGreeting() {
return "hello";
}
}

I know this is weird, I set up everything as instructed on the page but apparently nothing works, and I also checked other questions similar to this none of them answer my question.
It does seem that the tomcat server is hit, because it says when I make a call
o.s.web.servlet.DispatcherServlet : Completed initialization in 9 ms
but then I get with this call curl 'http://localhost:8080/demo/greeting' and with 'http://localhost:8080/demo/all'
curl : The remote server returned an error: (404) Not Found.

}
This works if I do this:
https://github.com/BraintoByte/Test_App_Stack/tree/master/demo
Different example:
I have attached a different example with hirarchy exactly the same but business logic omitted:
Code in controller:
package com.braintobytes.controllers;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;
import com.braintobytes.data.Currency;
import com.braintobytes.data.repository.CurrencyRepository;
#RestController
#RequestMapping("/demo")
public class CurrencyController {
#Autowired
private CurrencyRepository currencyRepository;
#GetMapping("/currency")
public String getCurrency() {
return "currency";
}
}
Project hierarchy:
Same exact pom and in application.properties:
spring.jpa.hibernate.ddl-auto=update
spring.datasource.url=jdbc:mydatabase
spring.datasource.username=myusername
spring.datasource.password=mypassword

Your controller is in package - com.example.accessingdatamysql
Spring boot startup log shows your main application class c.b.f.FinanceMicroserviceApplication is in another non related package hierarchy.
Spring boot recommends to locate main application class in a root package above other classes so that the component scan works out of box.
If you keep package com.example as root package and move your main application class FinanceMicroserviceApplication to it then everything should work as expected.
If you don't follow Spring boot recommendation for package hierarchy then you need to explicitly specify packages to scan with #SpringBootApplication annotation.

Alright so none of the suggestions above worked, we were on the right path though.
Changing the structure as so worked:
There was also a pathing problem in the application.properties and thus I changed as so:
spring.datasource.url=jdbc:mysql://${MYSQL_HOST:localhost}
To:
jdbc:mysql://localhost
And finally:
package com.braintobytes.finance.data.repository;
import org.springframework.data.repository.CrudRepository;
import com.braintobytes.finance.data.Currency;
public interface CurrencyRepository extends CrudRepository<Currency, Integer> {
}
Woah!

i have set up a cassandra.properties file setting the host and port and keyspacename, also there is a cassandra config java class that sets the connection parameters to connect to the cluster
here is the file:
package hello;

import org.springframework.data.cassandra.config.CassandraClusterFactoryBean;
import org.springframework.data.cassandra.core.mapping.BasicCassandraMappingContext;
import org.springframework.data.cassandra.core.mapping.CassandraMappingContext;

}
#Override
#Bean
public CassandraClusterFactoryBean cluster() {
final CassandraClusterFactoryBean cluster = new CassandraClusterFactoryBean();
cluster.setContactPoints(environment.getProperty("spring.data.cassandra.contact-points"));
cluster.setPort(Integer.parseInt(environment.getProperty("spring.data.cassandra.port")));
LOGGER.info("Cluster created with contact points [" + environment.getProperty("spring.data.cassandra.contact-points") + "] " + "& port [" + Integer.parseInt(environment.getProperty("spring.data.cassandra.port")) + "].");
return cluster;
}
//
// #Bean
// public CassandraClusterFactoryBean cluster() {
// CassandraClusterFactoryBean cluster =

// cluster.setContactPoints("192.168.164.130");
// cluster.setPort(9042);

return new BasicCassandraMappingContext();
}
// #Bean
// public CassandraMappingContext cassandraMapping()

// }
}
what else am i missing ?
EDIT : it turned out that i had to change the rpc_address in the cassandra.yml file in the vm host from localhost to the vm ip address, so its exposed to external connections

You spring.data.cassandra.port is missing or null. You can change to below code so that if it is not present then the code will use the default
#Value("${spring.data.cassandra.port: <cassandra port/9042>}")
private int port;

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;

import org.springframework.context.annotation.Profile;
import org.springframework.core.env.Environment;
import org.springframework.data.cassandra.config.CassandraClusterFactoryBean;
import org.springframework.data.cassandra.config.java.AbstractCassandraConfiguration;
import org.springframework.data.cassandra.mapping.BasicCassandraMappingContext;
import org.springframework.data.cassandra.mapping.CassandraMappingContext;
import org.springframework.data.cassandra.repository.config.EnableCassandraRepositories;
/**

*/
#Configuration
#EnableCassandraRepositories(basePackages = "com.xxx.abc.reposiroty.cassandra")
#ComponentScan(basePackages = "com.xxx.abc")
#Profile("cassandra")
public class CassandraConfig extends AbstractCassandraConfiguration {
private static final Log LOGGER = LogFactory.getLog(CassandraConfig.class);
#Override
protected String getKeyspaceName() {
return "agenthub";
}
#Override
#Bean
public CassandraClusterFactoryBean cluster() {
final CassandraClusterFactoryBean cluster = new CassandraClusterFactoryBean();
cluster.setContactPoints("localhost");
cluster.setPort(9042);
//LOGGER.info("Cluster created with contact points [" + environment.getProperty("cassandra.contactpoints") + "] " + "& port [" + Integer.parseInt(environment.getProperty("cassandra.port")) + "].");
return cluster;
}
#Override
#Bean
public CassandraMappingContext cassandraMapping() throws ClassNotFoundException {
return new BasicCassandraMappingContext();
}
}

You are adding a lot of boilerplate code that Spring handles for you, as long as your application.yml has the following properties:
spring:
data:
cassandra:
contact-points:
keyspace-name:
username:
password:
port:
and the dependency
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-cassandra</artifactId>
</dependency>
Spring will configure the connection for you, similar to Spring data for RDBMS.
You can then use the Cassandra Repository to query your tables:
#Repository
public interface YourRepository extends CassandraRepository<Item> {
//
}
And entity:
#Table
public class Item {
#PrimaryKeyColumn(
name = "id"
type = PrimaryKeyType.CLUSTERED)
private UUID id;
#PrimaryKeyColumn(
name = "key", type = PrimaryKeyType.PARTITIONED)
private String key;
#Column
private String data;
//Getter setters
}

How to connect mysql database in eclipse using maven and jpa?

I want to connect to mysql database from eclipse. I want to create a Rest Api and insert data in mysql database.
I am using sqlyog to connect to mysql and I have installed a xammp server, turned on the mysql and my project is located at tihs path C:\xampp\tomcat\webapps\
I have connected sql yog by giving the port on which mysql is running from xammp server.
Now I have created one maven project, which includes jpa dependency and properties.

How to resolve this? I am new to eclipse and web development. Please help.
Thank you.

Your application.properties seems to have wrong entries. The only ones you need are the following 4.
spring.datasource.url=jdbc:mysql://localhost/test
spring.datasource.username=dbuser
spring.datasource.password=dbpass
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
It is described here: https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-sql.html#boot-features-connect-to-production-database
Also where is your application.properties located?
SpringApplication will load properties from application.properties files in the following locations and add them to the Spring Environment:
A /config subdirectory of the current directory.
The current directory
A classpath /config package
The classpath root
https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-external-config.html

This exception is thrown by Spring when it is unable to find the application.properties file or unable to find the datasource.
Check if the application.properties is under src/main/resources. Also, remove \u2013 from the properties file
You have not specified the mysql port, are you sure you are able to connect it from command line directly?
Since you are running from eclipse, make sure you have added the start-up class appropriately and have #SpringBootApplication
<properties>
<start-class>org.xxx.xxx.YourClassName</start-class>
</properties>

Develop Reference

Java is a programming language and computing platform first released by Sun Microsystems in 1995.

Using #ConfigurationProperties in a #Scheduled annotation by referencing the bean name - java

Using #Componenton the properties class allows to access the property as "#{#someProperties.persistence.delay}. More info in the spring boot documentation.

Following should work fine assuming bean is created with someProperties by default and name is not overridden. #Scheduled(fixedDelayString = "#{#someProperties.getMillis()}")

Develop Reference

Java is a programming language and computing platform first released by Sun Microsystems in 1995.

Using #ConfigurationProperties in a #Scheduled annotation by referencing the bean name - java

Using #Componenton the properties class allows to access the property as "#{#someProperties.persistence.delay}. More info in the spring boot documentation.

Following should work fine assuming bean is created with someProperties by default and name is not overridden. #Scheduled(fixedDelayString = "#{#someProperties.getMillis()}")
