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…

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.
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…

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…
ContinueGet Auto-generated Id in Spring JDBC using SimpleJdbcInsert
Introduction In this post I will show you how to get auto generated id of a newly inserted row in table. Spring provides an easy way to get this auto-generated key using executeAndReturnKey() method of SimpleJdbcInsert which is supported Spring JDBC 3 onwards. For most of the records we use auto generated Id value on database side to avoid inconsistency while inserting value for the primary key Id field. So here I am not only going to show how to insert the auto generated Id value for the primary field,…
ContinueGet auto-generated id in Spring JDBC using PreparedStatement
In this post I will show you how to get auto generated id of a newly inserted row in table. Spring provides an easy way to get this auto-generated key using KeyHolder which is supported Spring JDBC 3 onward. I am going to use PreparedStatement to get the auto generated id value. For most of the records we use auto generated Id value on database side to avoid inconsistency while inserting value for the primary key Id field. So here I am not only going to show how to insert…
