Spring simplejdbctemplate encapsulates the call of the stored procedure, but unfortunately it can only be used in the jdk1.5 environment and cannot be used in the jdk1.4 environment. jdbctemplate is fully applicable to the jdk1.4 environment, the following describes how to use jdbctemplate to call an oracle st
Jdbctemplate was used in the project at the beginning. To improve the development efficiency, Hibernate was used. However, it was found that hibernate was not very efficient during batch operations. So now we use jdbctemplate and Hibernate to mix, jdbctemplate and hibernate can be mixed, there are several considerations.
1. If the

Tags: java development Spring jdbctemplate jdbc TemplateSpring's jdbctemplate is a template encapsulation of JDBC, which provides a set of JDBC templates that allow us to write persistent layer code to reduce redundant code, simplify the JDBC code, and make the code look more concise. Before we introduce spring's jdbctemplate
Paging
Recent use of the JdbcTemplate in spring to implement database query and insert operations, the discovery of spring jdbctemplate is not as good as hibernatetemplate, has implemented the paging function. So to implement it yourself, the result set that you get using Getjdbctemplate (). queryForList (String sql) i

The previous article was just a simple spring MVC framework and then added some interaction with the database.First, add JDBC-related configurationAfter adding dependent dependencies in Maven, configure database access parameters and data sources. Database parameters using the configuration file, the code is as follows: Jdbc.properties1Jdbc.driver=Com.mysql.jdbc.Driver2Jdbc.url=Jdbc:mysql://localhost3306/SampleDb3Jdbc.username=Root4Jdbc.password=12345

In the previous article, we used a single data source connection to access, insert data, but often as the volume of business development, we usually do the database split or introduce other databases, so we need to configure multiple data sources, The following is based on the previous jdbctemplate and SPRING-DATA-JPA examples of how the two multiple data sources are configured.

Spring has always been shanfanjiujian, so we have designed a very popular bean management model that simplifies the management of beans in development and writes a lot less repetitive code. JdbcTemplate's design is more impressive, lightweight, and can be used as an ORM as well as a JDBC-like flexibility. And in JdbcTemplate a class, contains two kinds of design patterns, read after the
