In this Spring MVC CRUD Example, we will be building a simple web-based Spring MVC Application (Employee management) which has the ability to perform CRUD Operations using Spring JdbcTemplate. Our Employee management application will have abilities to create a new employee, update the existing employee, get a particular employee/ all employee. Spring 4 JdbcTemplate Annotation Example. By Yashwant Chavan, Views 558927, Last updated on 15-Dec-2016. In this tutorial, we will learn how to connect to the database and execute CRUD SQL queries using Spring 4 JdbcTemplate. Select For Update Spring Jdbctemplate Average ratng: 3,5/5 4528 reviews Context: The framework used is Spring and all queries are run with JdbcTemplate. Mysql Server version is 5.6.19. Use the NamedParameterJdbcTemplate object which is called sqlDao to call update , pass in addCarsql (which has the query for inserting a car model). The call to update will return an integer that indicates how many rows have been affected. Finally, I print out the integer to see if it succeeded or not.

Introduction

Following example will demonstrate how to update a query using Spring JDBC. We'll update the available records in Student Table. To understand the above-mentioned concepts related to Spring JDBC, let us write an example which will update a query. To write our example, let us have a working Eclipse.

The JdbcTemplate class executes SQL queries, update statements and stored procedure calls, performs iteration over ResultSets and extraction of returned parameter values. It also catches JDBC exceptions and translates them to the generic, more informative, exception hierarchy defined in the org.springframework.dao package.

Instances of the JdbcTemplate class are threadsafe once configured so it can be safely inject this shared reference into multiple DAOs.

Basic Query methods

Some of the queryFor* methods available in JdbcTemplate are useful for simple sql statements that perform CRUD operations.

Querying for Date

Querying for Integer

OR

Querying for String

Spring Jdbctemplate Select For Update Example

Querying for List

Batch operations

JdbcTemplate also provides convenient methods to execute batch operations.

Jdbctemplate Run Update Query

Batch Insert

Batch Update

There are further batchUpdate methods which accept List of object array as input parameters. These methods internally use BatchPreparedStatementSetter to set the values from the list of arrays into sql statement.

NamedParameterJdbcTemplate extension of JdbcTemplate

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.

Query for List of Maps
