I'm using redis in my springboot rest application to store cache. But the problem I'm facing is once it is stored in redis my api only hits the redis not the database. I've added time out property it didn't work. I've tried CacheManager to get the cache and call CacheEvict to clear the cache and then CachePut to put the data again, but it didn't work. These are the things I've tried so far. I wanted my redis cache to refresh after a given time set by me. Any advice on this? Here is my code below:

I'm trying to persist a cassandra entity but on startup I get:
Caused by: org.springframework.data.mapping.MappingException: Couldn't find PersistentEntity for type class com.service.model.Cart!
This is my entity class:
package com.service.model;
import io.vavr.collection.LinkedHashMap;
import io.vavr.collection.Map;
import lombok.Getter;
import lombok.ToString;
import org.springframework.data.cassandra.core.mapping.PrimaryKey;

public Cart(UUID uuid) {

}
private Cart(UUID uuid, Map<CartItemKey, CartItem> items) {
this.uuid = Objects.requireNonNull(uuid, "Cart's uuid cannot be null");
this.items = Objects.requireNonNull(items, "Cart's items cannot be null");
}
}
This is my CassandraConfig:
package com.service.configuration;
import com.service.model.Cart;
import com.fasterxml.jackson.databind.ObjectMapper;
import org.springframework.beans.factory.annotation.Value;

} catch (IOException e) {

}
}
return null;
}
}
}
And lastly my Application:
package com.service.cart;
import org.axonframework.springboot.autoconfig.AxonServerAutoConfiguration;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;

#EnableCassandraRepositories(basePackages = "com.service.repository")
public class Application extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
What seems puzzling to me is that when I remove customConversions() bean it fails with a different error - not being able to map vavr Map, so spring must have scanned and registered this entity so that it got inspected. This is expected while it is not cassandra data type but in my understanding adding my custom conversions should solve this problem.
I also tried experimenting with #EntityScan with the same results.
Any help would be appreciated.
I'm putting together a simple Spring Boot app, and having an issue with an #Autowired field not "showing up".
My main app class:
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
#SpringBootApplication
public class SpringElasticCatalogApi {
public static void main(String[] args) {
SpringApplication.run(SpringElasticCatalogApi.class, args);
}
}
My Repository class:
import com.discover.harmony.elastic.model.Customer;
import org.springframework.data.elasticsearch.repository.ElasticsearchRepository;
import org.springframework.stereotype.Component;
import java.util.List;
#Component
public interface CustomerRepository extends ElasticsearchRepository<Customer, String> {
public Customer findByFirstName(String firstName);
public List<Customer> findByLastName(String lastName);
}
This class ("Loaders") requires an #Autowired repository field, which is NULL:
import com.discover.harmony.elastic.model.BusinessMetadata;
import com.discover.harmony.elastic.model.Customer;
//import com.discover.harmony.elastic.repository.CustomerRepository;
import com.discover.harmony.elastic.api.CustomerRepository;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.elasticsearch.repository.ElasticsearchRepository;
import org.springframework.stereotype.Component;
import org.springframework.transaction.annotation.Transactional;
import javax.annotation.PostConstruct;
import java.util.ArrayList;
import java.util.List;
//#Configuration
#Component
public class Loaders {
#Autowired
private CustomerRepository repository;
#PostConstruct
#Transactional
public void loadAll(){
this.repository.deleteAll();
saveCustomers();
fetchAllCustomers();
fetchIndividualCustomers();
}
private void saveCustomers() {
this.repository.save(new Customer("Alice", "Smith"));
this.repository.save(new Customer("Bob", "Smith"));
}
private void fetchAllCustomers() {
System.out.println("Customers found with findAll():");
System.out.println("-------------------------------");
for (Customer customer : this.repository.findAll()) {
System.out.println(customer);
}
System.out.println();
}
private void fetchIndividualCustomers() {
System.out.println("Customer found with findByFirstName('Alice'):");
System.out.println("--------------------------------");
System.out.println(this.repository.findByFirstName("Alice"));
System.out.println("Customers found with findByLastName('Smith'):");
System.out.println("--------------------------------");
for (Customer customer : this.repository.findByLastName("Smith")) {
System.out.println(customer);
}
}
private List<BusinessMetadata> getData() {
List<BusinessMetadata> metadata = new ArrayList<>();
metadata.add(new BusinessMetadata((long)1,"TradeLine"));
metadata.add(new BusinessMetadata((long)2,"Credit Line"));
metadata.add(new BusinessMetadata((long)3,"Other Line"));
return metadata;
}
}
What should I change, to make the #Autowire work as expected here?
The problem is that your example is not complete on implementing the ElasticSearch. To proof this, turn your CustomerRepository into a class and remove ElasticsearchRepository<Customer, String> then everything goes fine.
What you need to do is adding a new Configuration class, with #EnableElasticsearchRepositories(basePackages = "com.discover.harmony.elastic.api.CustomerRepository") to scan the provided package for Spring Data repositories.
You can find a complete example here.
I'm trying to put together an SDK that uses Spring internally through a context it manages of its own. I want the jar that gets built to be usable regardless of whether or not Spring is in use on the application that wants to use the SDK.
I have something that works when it is running on its own. However if I attempt to use the SDK inside another Spring context (in my case a Spring Boot based application) I get a org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type exception.
Try as I might I cannot understand how to get this working, or indeed what I am doing wrong. The classes below show what I'm doing, the org.example.testapp.MySDKTest fails with the exception while the org.example.test.MySDKTest successfully passes. Sorry there is so much code but I can't reproduce the issue with a simplified case.
SDK source
package org.example.mysdk;
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.AnnotationConfigApplicationContext;
import org.example.mysdk.MyService;
import org.example.mysdk.MyServiceConfiguration;
public final class MySDK {
private static ApplicationContext applicationContext;
public static <T extends MyService> T getService(Class<? extends MyService> clazz, MyServiceConfiguration configuration) {
T tmp = (T) getApplicationContext().getBean(clazz);
tmp.setConfiguration(configuration);
return tmp;
}
private static ApplicationContext getApplicationContext() {
if (applicationContext == null) {
applicationContext = new AnnotationConfigApplicationContext(SpringContext.class);
}
return applicationContext;
}
}
.
package org.example.mysdk;
import org.springframework.beans.factory.annotation.Autowired;
public abstract class MyService {
private MyServiceConfiguration configuration;
#Autowired
private MyAutowiredService myAutowiredService;
MyService() {
}
MyService(MyServiceConfiguration configuration) {
super();
this.configuration = configuration;
}
public MyServiceConfiguration getConfiguration() {
return configuration;
}
void setConfiguration(MyServiceConfiguration configuration) {
this.configuration = configuration;
}
String getSomething(String in) {
return "something + " + myAutowiredService.getThing(configuration.getValue()) + " and " + in;
}
}
.
package org.example.mysdk;
import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Service;
#Service
#Scope("prototype")
public class MyServiceImpl1 extends MyService {
public MyServiceImpl1() {
}
public MyServiceImpl1(MyServiceConfiguration configuration) {
super(configuration);
}
public String method1() {
return this.getSomething("method1");
}
}
.
package org.example.mysdk;

public void setValue(String value) {
this.value = value;
}

return value;
}
}
.
package org.example.mysdk;

}
}

Tests
This first test fails with a org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type exception,
package org.example.testapp;
import static org.junit.Assert.*;
import org.example.mysdk.MyServiceConfiguration;
import org.example.mysdk.MyServiceImpl1;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.support.AnnotationConfigContextLoader;
#RunWith(SpringJUnit4ClassRunner.class)
#ContextConfiguration(classes = App.class, loader = AnnotationConfigContextLoader.class)
public class MySDKTest {
#Autowired
MyServiceImpl1 service;
#Test
public void test() {
MyServiceConfiguration conf = service.getConfiguration();
assertEquals(conf.getValue(), "this is the instance configuration");
}
}
.
package org.example.testapp;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.example.mysdk.MySDK;
import org.example.mysdk.MyServiceConfiguration;
import org.example.mysdk.MyServiceImpl1;
#Configuration
#ComponentScan(basePackages = {
"org.example.testapp"
})
public class App {
#Bean
public MyServiceImpl1 myServiceImpl1() {
MyServiceConfiguration configuration = new MyServiceConfiguration();
configuration.setValue("this is the instance configuration");
return MySDK.getService(MyServiceImpl1.class, configuration);
}
}
and this test succeeds,
package org.example.test;
import static org.junit.Assert.*;
import org.example.mysdk.MySDK;
import org.example.mysdk.MyServiceConfiguration;
import org.example.mysdk.MyServiceImpl1;
import org.junit.Test;
public class MySDKTest {
#Test
public void test() {
MyServiceConfiguration configuration = new MyServiceConfiguration();
configuration.setValue("this is the instance configuration");
MyServiceImpl1 service = MySDK.getService(MyServiceImpl1.class, configuration);
assertEquals(service.getConfiguration().getValue(), "this is the instance configuration");
}
}
If I've gone about this the completely wrong way I'm happy to hear suggestions of how this should be done differently!
You have to modify two files.
First App.java, it should scan for "org.example.mysdk" package to inject myAutowiredService in abstract class MyService, If not it has to be created in App.java. And the name of the MyServiceImpl1 bean must be different from myServiceImpl1 as it will conflict.
package org.example.testapp;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.example.mysdk.MySDK;
import org.example.mysdk.MyServiceConfiguration;
import org.example.mysdk.MyServiceImpl1;
#Configuration
#ComponentScan(basePackages = {
"org.example.testapp", "org.example.mysdk"
})
public class App {
#Bean
public MyServiceImpl1 myServiceImpl() {
MyServiceConfiguration configuration = new MyServiceConfiguration();
configuration.setValue("this is the instance configuration");
return MySDK.getService(MyServiceImpl1.class, configuration);
}
}
Then secondly in MySDKTest.java should inject myServiceImpl which was created in App.java
import static org.junit.Assert.*;
import org.example.mysdk.MyServiceConfiguration;
import org.example.mysdk.MyServiceImpl1;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.support.AnnotationConfigContextLoader;
#RunWith(SpringJUnit4ClassRunner.class)
#ContextConfiguration(classes = App.class, loader = AnnotationConfigContextLoader.class)
public class MySDKTest {
#Autowired
MyServiceImpl1 myServiceImpl;
#Test
public void createOxiAccountService() {
MyServiceConfiguration conf = myServiceImpl.getConfiguration();
assertEquals(conf.getValue(), "this is the instance configuration");
}
}

My output says "Sucks", and "DI DOESN'T WORK". When I tried to get ResponseGenerator bean from ApplicationConfig, there wasn't null. I've no idea what's wrong. Thanks in advance.
Just started using MongoDB with JAVA.
Set up the following JavaObject
package com.foo.bar
import org.springframework.data.annotation.Id;
import org.springframework.data.mongodb.core.mapping.Document;
#Document(collection = "cameras")
public class Camera {
#Id
private int id= -1;
String name = "";
String orientation = "";
boolean tempdis = false;
int refreshRate = -1;
String cityCode = "";
String provider = "";
Location location;
//Gets & Sets Below
}
I then have the following config
package com.foo.bar.config
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.mongodb.MongoDbFactory;
import org.springframework.data.mongodb.core.MongoTemplate;
import org.springframework.data.mongodb.core.SimpleMongoDbFactory;
import com.mongodb.MongoClient;
#Configuration
public class SpringMongoConfig {
public #Bean
MongoDbFactory mongoDbFactory() throws Exception {
return new SimpleMongoDbFactory(new MongoClient(), "myDB");
}
public #Bean
MongoTemplate mongoTemplate() throws Exception {
MongoTemplate mongoTemplate = new MongoTemplate(mongoDbFactory());
return mongoTemplate;
}
}
And in my main application
package com.foo.bar
import java.util.List;
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.AnnotationConfigApplicationContext;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.mongodb.core.MongoOperations;
import org.springframework.data.mongodb.repository.config.EnableMongoRepositories;
import com.foo.bar.config.SpringMongoConfig;
import com.foo.bar.Camera;
#Configuration
#EnableMongoRepositories
public class Application {
public static void main(String[] args) {
ApplicationContext ctx = new AnnotationConfigApplicationContext(
SpringMongoConfig.class);
MongoOperations mongoOperation = (MongoOperations) ctx
.getBean("mongoTemplate");
List<Camera> listUser = mongoOperation.findAll(Camera.class);
System.out.println(listUser.size());
}
}
Running this code is getting me a size of 0. However, in the command line I get the following
C:\mongodb\bin>mongo.exe
MongoDB shell version: 2.4.8
connecting to: test
> use myDB
switched to db myDB
> db.Camera.count()
1018

Is there something I'm missing?
#Document(collection = "cameras")
public class Camera {
Camera is mapped to collection cameras in your code.
and you are looking up in collection Camera using db.Camera.count()
