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.
In order to utilize a JDBC datasource, we must first set up a JNDI reference in Tomcat. After the JNDI reference is made, JDBC datasources can be used within our Tomcat server and applications using shared or independent references (Great for
prod setup, or removing connection strings/credentials from committed code).
This describes how to directly obtain a SqlRowSet using SimpleJdbcCall with a stored procedure in your database that has a cursor output parameter,
I am working with an Oracle database, I've attempted to create an example that should work for other databases, my Oracle example details issues with Oracle.
SQL injection is a code injection technique, used to attack data-driven applications, in which nefarious SQL statements are inserted into an entry field for execution (e.g. to dump the database contents to the attacker).
In this section we will talk about that and its relation with JDBC Statement.
Spring Boot can be used to build and persist a SQL Relational DataBase. You can choose to connect to an H2 in memory DataBase using Spring Boot, or perhaps choose to connect to MySql DataBase, it's completely your choice. If you want to conduct CRUD operations against your DB you can do it using JdbcTemplate bean, this bean will automatically bean be provided by Spring Boot. Spring Boot will help you by providing auto configuration of some commonly used beans related to JDBC.
