In this post under Spring Retry, I will show with example how to configure StatisticsListener using interceptor. Below is the complete xml code which shows how to configure StatisticsListener using interceptor. XML Code 1 <?xml version=”1.0″ encoding=”UTF-8″?>2 <beans xmlns=”http://www.springframework.org/schema/beans”3 xmlns:xsi=”http://www.w3.org/2001/XMLSchema-instance”4 xmlns:aop = “http://www.springframework.org/schema/aop”5 xsi:schemaLocation=”http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd6 http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd”>7 <aop:config>8 <aop:pointcut id=”transactional” expression=”execution(* defaultPackage.Service1.executeWithException(..))”/>9 <aop:advisor pointcut-ref=”transactional” advice-ref=”retryAdvice”/>10…… Continue reading Configuring StatisticsListener (using interceptor)
ignoreIfMissing method example
In this post under DotEnv I will show with example what is the purpose of “ignoreIfMissing” method with an example. In my previous posts I showed with example how to load environment files whether it is “.env” file or custom env file like “custom-file.env”. The default behavior of DotEnv framework is that if the environment…… Continue reading ignoreIfMissing method example
Wiring together @Bean annotated beans using setter approach
In this post under Spring Core, I will explain with example how to wire two beans annotated with @Bean annotation using setter methods. For our example lets take the below two classes. Bean1 package package12; public class Bean1 { private Bean2 bean2; public Bean1() { } public void setBean2(Bean2 bean2) { this.bean2 = bean2; }…… Continue reading Wiring together @Bean annotated beans using setter approach
Configuring Recovery Callback (using interceptor)
In this post under Spring Retry –> XML Configuration –> Spring AOP, I will show with example how to configure RecoveryCallback using Spring AOP. For our example we will create a recovery class as shown below CustomMethodInvocationRecoverer package defaultPackage; import org.springframework.retry.interceptor.MethodInvocationRecoverer; public class CustomMethodInvocationRecoverer implements MethodInvocationRecoverer<Void> { @Override public Void recover(Object[] args, Throwable cause) {…… Continue reading Configuring Recovery Callback (using interceptor)
Changing scopes of @Bean annotated beans
In this post under Spring Core, I will explain with example how to change scopes of Spring beans annotated with “@Bean” annotation. By default the “@Bean” annotated beans have singleton scope. Which means that whenever a dependee bean asks for a reference to dependent bean and the dependent bean scope is “singleton” then Spring makes…… Continue reading Changing scopes of @Bean annotated beans
Loading environment properties from custom .env file
In all my previous post under DotEnv, I showed how to load environment properties from a file named “.env”. The “.env” file can be present in the project directory or in some other directory. By default, DotEnv is configured to search under project directory. In one of my previous posts, I showed how to change…… Continue reading Loading environment properties from custom .env file
Wiring together @Bean annotated beans using constructor approach
In this post under Spring Core, I will explain with example how to wire two beans annotabed with @Bean annotation using constructor. For our example lets take the below two bean classes. Bean1 package package10; public class Bean1 { private Bean2 bean2; public Bean1(Bean2 bean2) { System.out.println(“Hello its Bean1”); this.bean2 = bean2; } } As…… Continue reading Wiring together @Bean annotated beans using constructor approach
Using @DependsOn with @Component annotation
In this post under Spring Core, I will show with example how to use “@DependsOn” annotation to indicate dependencies between two beans marked with “@Component” annotation. For our example we have two beans “Bean1” and “Bean2” and both are annotated with “@Component” annotation. Now to declare that “Bean2” is dependent on “Bean1”, we annotate the…… Continue reading Using @DependsOn with @Component annotation
Giving custom name to @Component annotated beans
In this post under Spring Core, I will show with example how to give custom names to classes annotated with “@Component” annotation. By default when we annotate a class with “@Component” annotation, the name of the bean will be created from the class name, where the first letter of the class name will be lowercase.…… Continue reading Giving custom name to @Component annotated beans
Loading .env file from a specific folder
In previous post under DotEnv, I showed that by default DotEnv checks for “.env” file in the project directory when static “load” method is called. So if your project directory is in “D:\ProgrammingConcepts\JavaSEConcepts\DotEnvConcepts” the “.env” file should be present directly under the “DotEnvConcepts” folder. If present in subfolders under “DotEnvConcepts” it will not load that…… Continue reading Loading .env file from a specific folder
