In this example we will show you how to convert java object to JSON using Gson library. Gson is a Java library that can be used to convert Java Objects into their JSON representation. It can also be used to convert a JSON string to an equivalent Java object.
In this blog we will insert a record into the database using Statement. For this we need to add following dependencies into our pom.xml. Continue Reading
In the previous post we saw how to create table with Statement. And now we will create the table with PreapareStatement.
In this example we can see how we can create a table with jdbc statement. In the pom.xml we need to add following two dependencies:
In this example I will show how to connect to mysql with JDBC driver. Let’s create the maven project with following pom.xml
Let’s create an application which will use spring data jpa to store the user into the database.
In this blog we will create the custom annotation using spring and aspectj lib. So let’s assume that we have a rest API and we want to validate the request object for post requests.
Let’s have a look how we can encrypt the user’s password before inserting into the database. Spring provides the PasswordEncoder interface which has multiple implementation. For example let’s use StandardPasswordEncoder.
A standard PasswordEncoder implementation that uses SHA-256 hashing with 1024 iterations and a random 8-byte random salt value. It uses an additional system-wide secret value to provide additional protection.

So let’s understand how we can validate the fields before inserting into mongo db. So after the previous blog about the spring data mongodb example, let’s continue understand how we can add the validate the fields before inserting into mongo db.
Let’s create a mongo db application with spring data to do some simple operations.
