Property from PropertySource is not used - java

I've got a question for programmatically added properties to a spring context.
GenericXmlApplicationContext ctx = new GenericXmlApplicationContext();
ConfigurableEnvironment ctxEnvironment = ctx.getEnvironment();
ctxEnvironment.getPropertySources().addFirst(new ResourcePropertySource("rootProperties", new FileSystemResource("/tmp/root.properties")));
ctx.load(new ClassPathResource("/context/application-context.xml"));
ctx.refresh();
root.properties:
test=hello
Snippet from application context:
...
<property name="test" value="${test} world"/>
...
When I load the bean from the context, ${test} is not substituted with "hello".
Spring version: 5.1.5.RELEASE
What am I missing here?
PS: Btw, this works:
System.out.println("Text: " + ctxEnvironment.resolvePlaceholders("${test}"));
Output:
Text: hello
EDIT: Sorry, I forgot to add: I don't want to use the context:property-placeholder bean, because I know the location of the properties file only at runtime.

I reproduced your case and it's working for me. You need to add a property place holder in your applicationContext.xml file :
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd">
<context:property-placeholder location="file:/tmp/root.properties" />
<bean id="myA" class="com.zpavel.MyA">
<property name="test" value="${test}" />
</bean>
</beans>
For example a simple bean :
public class MyA {
private String test;
public String getTest() {
return test;
}
public void setTest(String test) {
this.test = test;
}
}
You can load it with :
ApplicationContext context = new ClassPathXmlApplicationContext("classpath:/context/application-context.xml");
MyA myA = context.getBean(MyA.class);
System.out.println(myA.getTest());
It will print "hello" as expected.

Your code is working fine.
I have tested with this.
applicationContext.xml :
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd">
<context:property-placeholder
location="application.properties" />
<bean id="demo"
class="com.example.Demo">
<property name="value1" value="${test} world" />
</bean>
</beans>
application.properties :
test = Hello
Demo.java :
public class Demo {
String value1;
public String getValue1() {
return value1;
}
public void setValue1(String value1) {
this.value1 = value1;
}
#Override
public String toString() {
return value1;
}
}
Test.java :
public class Test {
public static void main(String[] args) {
ClassPathXmlApplicationContext classPathXmlApplicationContext = new ClassPathXmlApplicationContext(
"applicationContext.xml");
Demo demo = (Demo) classPathXmlApplicationContext.getBean("demo");
System.out.println(demo);
classPathXmlApplicationContext.close();
}
}
When you run, the output :
Hello world
The problem is with the bean. Please check it.

After some more diving into the spring API I found a pure programmatic solution to my problem without the need of a context:property element. For anyone interested, here is the full source:
Test.java
public class Test {
public static void main(String[] args) throws Exception {
GenericXmlApplicationContext ctx = new GenericXmlApplicationContext();
PropertySourcesPlaceholderConfigurer configurer = new PropertySourcesPlaceholderConfigurer();
MutablePropertySources propertySources = new MutablePropertySources();
propertySources.addFirst(new ResourcePropertySource("rootProperties", new ClassPathResource("/root.properties")));
configurer.setPropertySources(propertySources);
ctx.addBeanFactoryPostProcessor(configurer);
ctx.load(new ClassPathResource("/ctx.xml"));
ctx.refresh();
TestBean bean = ctx.getBean(TestBean.class);
System.out.println(bean.getString());
}
}
TestBean.java
public class TestBean {
String string = "";
public String getString() { return string; }
public void setString(String string) { this.string = string; }
}
ctx.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans classpath:/org/springframework/beans/factory/xml/spring-beans.xsd">
<beans>
<bean class="TestBean">
<property name="string" value="${test} world"/>
</bean>
</beans>
</beans>
root.properties

Spring Cloud Gateway injection in Unit Tests is not Working

I have a Global Filter with an injected attribute.
public class AuthenticationGlobalFilter implements GlobalFilter, Ordered {
#Autowired
private Permission permission;
#Override
public Mono<Void> filter(ServerWebExchange exchange, GatewayFilterChain chain) {
long serviceId = 0;
try {
ServerHttpRequest request = exchange.getRequest();
HttpHeaders headers = request.getHeaders();
String fromKey = headers.getFirst("x-api-key");
String fromIp = headers.getFirst("x-forwarded-for");
String fromSubject = headers.getFirst("******");
URI rqUrl = request.getURI();
String path = rqUrl.getPath();
serviceId = Long.parseLong(path.split("/")[6]);
permission.check(permission.identity(fromKey, fromSubject, fromIp), serviceId);
return chain.filter(exchange);
} catch (PermissionException e) {
exchange.getResponse().setStatusCode(HttpStatus.FORBIDDEN);
} catch (IllegalArgumentException e) {
exchange.getResponse().setStatusCode(HttpStatus.BAD_REQUEST);
} catch (Exception e) {
exchange.getResponse().setStatusCode(HttpStatus.INTERNAL_SERVER_ERROR);
}
return Mono.empty();
}
}
Injection works perfectly when I run the application
#EnableDiscoveryClient
#SpringBootApplication
#EnableConfigurationProperties(ApiGatewayProperties.class)
#Import({ PermitAllSecurityConfiguration.class, CustomAttributesConfiguration.class })

public class ApiGatewayUnicoApplication {
public static void main(String[] args) {
SpringApplication.run(ApiGatewayUnicoApplication.class, args);
}
}

Solved by annotating the dependency with #Lazy

Couldn't pass the #bean value to another class through Autowiring

I am new to spring. So I couldn't figure out what issue is there in the below code. I have two classes. I am defining a #Bean Channel and am autowiring that bean in the next class. I am using annotation for autowiring. When I try " System.out.println(externalChannel.toString());" am getting null values and the exception null pointer exception is thrown.
#Configuration
public class MessagingConfig
{
#Value("${service.name}")
private String queueName; // NOSONAR
#Value("${${user}")
private String schema;
#Value("${Owner}")
private String owner;
#Bean
public Channel externalChannel()
{
EventsProvider eventsProvider = new EventsProvider();
eventsProvider.setOwner(owner);
System.out.println("-------Cost And Events Channel-------"+eventsProvider.getEventsChannel());
return eventsProvider.getEventsChannel();
}
}
And Another class is
#Component
#LoggedService
#Monitored(useActualType = true)
public class MessagePublish {
#Autowired
private MessagingService messageService;
#Autowired
private Channel externalChannel;
public void publishTPSMessage(SourceTransaction sourceTransaction)
{
TPSEvent event = new TPSEvent(ContextHolder.getContextId(), new Date(), GuidUtils.generateGuid(),sourceTransaction);
Message<TPSEvent> message = new Message<TPSEvent>(event);
message.getHeader().setMessageType(TPSEvent.class.getName());
message.getHeader().setPayloadEncodingType(SystemCodecs.XML.name());
System.out.println(message.toString());
System.out.println(externalChannel.toString());
messageService.publish(externalChannel, message);
}
}
More Info
public Channel getEventsChannel() {
return Channel.builder()
.setName("necessarySources")

You need to initialize a Spring context at the start of your application when you do not create a servlet / run as a Server.
See Using Spring in a standalone application

Spring service class extends AbstractService and implements interface [duplicate]

I was using spring to create objects through beans. Now I tried to use aop to create the same object and I get $Proxy cannot be cast to SaleRoom exception.

And I used the following code to create the sales:
ApplicationContext context = new FileSystemXmlApplicationContext(SalesManager.getSalesSourceFile());
SaleRoom saleRoom;
List<String> salesNames = new LinkedList<String>();
List<SaleRoom> allSales = new LinkedList<SaleRoom>();
// Get all sales id's for beans

}
for (String saleName : salesNames) {
if(saleName.contains("sale")) {

I'm using the same code for creating the beans via aop. and I get
Exception in thread "main" java.lang.ClassCastException: $Proxy11 cannot be cast to application.common.entities.SaleRoom
The line that throws the exception:
saleRoom = (SaleRoom) context.getBean(saleName);
Any help will be appreciated. Thanks.
Does your SaleRoom class implement some interface? If yes, then you should use interface and not class in you code:
ISaleRoom saleRoom = (ISaleRoom) context.getBean(saleName);
Because if your bean implements some interface then Spring by default will create proxy based on this interface.
Here is a good article about proxy creation in Spring.
Also you can change proxying mechanism for Spring AOP if you want to create proxy for target class. This is described here in reference documentation.

Spring - what is wrong with my Autowiring?

I've this basic spring application in which the value of my #Autowired field is null in output. What is wrong here?
package com.spring;
import org.springframework.beans.factory.annotation.Autowired;
public class HelloWorld {
private String message;
#Autowired
private Double pi;
public HelloWorld(String message){
this.message = message;
}
public void setMessage(String message){
this.message = message;
}
public void getMessage(){
System.out.println("Your Message : " + message);
System.out.println("autowired: "+pi);
}
}

}
The output is:

You need to configure the context to allow autowiring. See this answer:
how do I configure autowire in spring
You need to add <context:annotation-config/> in your spring.xml file which will scan for spring annotations in your java files. Hope this helps.
