Introduction In my other tutorial I had shown how to create an example on Spring MVC and JDBC CRUD example using annotations only, but here I am going to use Spring Boot framework. I did not update the other tutorial keeping in mind if someone still needs the example using Spring framework only. Here also I am going to show you the same example but using Spring Boot framework. We are going to use both gradle and maven build tools to build the application. We are going to see how…
ContinueTag: Spring JdbcTemplate
Select Records using queryForObject, queryForList, BeanPropertyRowMapper in Spring JdbcTemplate
Introduction In this post we will see how to select records using queryForObject, queryForList, BeanPropertyRowMapper in Spring JdbcTemplate. Here we will create annotation based example. If you need XML based application then you can refer to the example here. Spring’s queryForObject is used to fetch single row from the database. Spring’s queryForList and BeanPropertyRowMapper are used to fetch multiple rows from the database. Therefore we will fetch single and multiple rows from the database using Spring JdbcTemplate.
ContinueBatch Insertion using Spring JdbcTemplate
Introduction In this post we will see an example on batch insertion using Spring JdbcTemplate. We had seen the similar example using XML configuration previously but here we will create annotation based application. So we will see how we can insert a large data-set into a database at once using Spring JdbcTemplate. Sometimes we need to insert or update large number of records in the database. It’s not a good idea to insert multiple records into database one by one in a traditional approach. It will hit the application’s performance.…
ContinueSingle and Multiple Record Insert using Spring JdbcTemplate
Introduction We will see example on single and multiple insert using Spring JdbcTemplate. We have seen similar example using XML based configuration but here we will see annotation based configuration to insert single or multiple records into database table. We will use here MySQL server 8.0.17 with Spring JdbcTemplate to insert data into database table. We can insert one or multiple records into database one by one in a traditional approach. Spring provides insert operation with the help of JdbcTemplate, it inserts or updates records into database in one shot.…
ContinueSpring Boot MVC with Maven
The primary motivation behind developing Spring Boot is to simplify the process for configuring and deploying the spring applications. Spring Boot will get rid of all the fuss involved on configuring the dependencies for building the enterprise applications. In Spring based applications, configurations are loaded with a bunch of XML files, now these configurations should not be maintained in a separate file which is extra work for the developers. Developers need to focus on only writing the application while Spring Boot will simplify the deployment process by packaging and deploying…
ContinueSpring MVC and JDBC CRUD with zero XML
In my other tutorials Spring MVC CRUD example with JDBC Spring MVC and Spring JDBC Example , Spring MVC and JDBC CRUD Example I have used XML configurations but in this tutorial I have used only Annotation, so it means it uses zero XML configurations. This example shows how MVC(Model, View, Controller) works in Spring 4.x. In this tutorial you will also find how JDBC works with Spring MVC. We will also see how annotation like @Autowired works in Spring. You will also see how DispatcherServlet, DataSource and ViewResolver are configured in…

We will also see how annotation like @Autowired works in Spring MVC and JDBC CRUD example. You will also see how datasource is configured in Spring. In this example we will see how to integrate Spring 4, MySQL with Maven 3. Related Posts: Spring MVC and Spring JDBC Example Spring MVC and JDBC CRUD with zero XML
ContinueSpring NamedParameterJdbcTemplate and Collections.singletonMap Example
Introduction In this post I will show you how to use NamedParameterJdbcTemplate and Collections.singletonMap to execute query for returning result. The NamedParameterJdbcTemplate class adds support for programming JDBC statements using named parameters, as opposed to programming JDBC statements using only classic placeholder (?) arguments. The NamedParameterJdbcTemplate class wraps a JdbcTemplate, and delegates to the wrapped JdbcTemplate to do much of its work. An SqlParameterSource is a source of named parameter values to a NamedParameterJdbcTemplate. The Collections.singletonMap returns an immutable map, mapping only the specified key to the specified value. The…
ContinueSpring NamedParameterJdbcTemplate and BeanPropertySqlParameterSource Example
In this post I will show you how to use NamedParameterJdbcTemplate and BeanPropertySqlParameterSource to execute query. The NamedParameterJdbcTemplate class adds support for programming JDBC statements using named parameters, as opposed to programming JDBC statements using only classic placeholder (?) arguments. The NamedParameterJdbcTemplate class wraps a JdbcTemplate, and delegates to the wrapped JdbcTemplate to do much of its work. An SqlParameterSource is a source of named parameter values to a NamedParameterJdbcTemplate. The BeanPropertySqlParameterSource class is an implementation of SqlParameterSource interface. This class wraps an arbitrary Java Bean (that is, an instance…
ContinueSpring NamedParameterJdbcTemplate and MapSqlParameterSource Example
In this post I will show you how to use NamedParameterJdbcTemplate and MapSqlParameterSource to execute query for inserting or retrieving results from database table. The NamedParameterJdbcTemplate class adds support for programming JDBC statements using named parameters, as opposed to programming JDBC statements using only classic placeholder (?) arguments. An SqlParameterSource is a source of named parameter values to a NamedParameterJdbcTemplate. The MapSqlParameterSource class is an implementation of SqlParameterSource interface. The MapSqlParameterSource class is a very simple implementation that is simply an adapter around a java.util.Map, where the keys are the…
