Handling Exception Using Spring's Aspect Oriented Programming

In this post, I will show you how we can handle exceptions using springs aspect-oriented programming.
Prerequisites
To follow this article you should have

  • JDK 8+  
  • gradle 2.3 + 
  • Your favorite IDE (I used IntelliJ Idea)
Folder Structure
The folder structure should be as follows
 aopexeptionhnadling
├── build.gradle
└── src
    ├── main
    │   └── java
    │       └── net
    │           └── asifhossain
    │               └── aopexceptionhandling
    │                   ├── aop
    │                   │   └── ExceptionLoggerPointCut.java
    │                   ├── AopExampleApp.java
    │                   └── service
    │                       └── ExceptionalService.java
    └── test
        └── java
            └── net
                └── asifhossain
                    └── aopexceptionhandling
                        └── AopExampleAppTest.java
Creating Gradle Build File
Create a file named build.gradle in application with the following content
build.gradle


Creating the service
Now let's create a service method which will throw exception


Now let's create an aspect configuration file to log all the exception thrown from service method
ExceptionLoggerPointCut.java


Create The Application class
Now create the application class with all the component
AopExampleApp.java


Run The Application
To run the application run the following command
gradle bootRun
You will see the thrown application is logged on the console.
That's all for today. Thanks for reading.
You can find all the codes in my GitHub repository

Refactoring Comparators in Java 8

In this article, I will show how  we  can refactor our old ugly comparators to cool elegant one. Example Domain Class Employee { private int salary; private int yearsOfExperience; int getSalary() { return salary; } public int getYearsOfExperience() { return yearsOfExperience; } } Use Case Sort a list of  Employee  class by  salary ,  yearsOfExperience  etc. Java 7 Code Sorting By Salary employees.sort(new Comparator<Employee>() { @Override public int compare(Employee o1, Employee o2) { return o1.getSalary() - o2.getSalary(); } }); Sorting By Years of Experience employees.sort(new Comparator<Employee>() { @Override public int compare(Employee o1, Employee o2) { return o1.getSalary() - o2.getSalary(); } }); This code looks ugly. Actually, it became ugly after the introduction of lambda operator. Refactoring in Java 8 Java8  introduced a new operator

What is a View in oracle?

View in Oracle A view in Oracle database is simply a SELECT query that is given a name and stored in memory for later use. A view can be made joining one or more table and later be queried like a virtual table. How to Create a View Suppose we have the following query. SELECT customerid , customername FROM customers WHERE countryid = 'US' ; Now we can create a view with this query as follows CREATE VIEW us_customers AS SELECT customerid , customername FROM customers WHERE countryid = 'US'; Now, this view can be used instead of the full query SELECT customerid , customername FROM us_customers WHERE customerId > 50 ; Oracle will transform the query into following one SELECT * FROM ( select customerid , customername from customers WHERE countryid = 'US' ) WHERE customerid BETWEEN 100 AND 200 How to Update a View To update a view we can use CREATE OR REPLACE VIEW statement to update a view CREATE OR REPLACE VI
