spring boot 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

Application:Use spring's jdbctemplate to query the database, get a list of lists of results, database table fields and entity classes automatically correspond, you can use beanpropertyrowmapper.Note:Automatic binding requires the same column name as the Java entity class name, such as: The property name "UserName" can match the column field "UserName" or "user_name" in the database. In this way, we do not need a manual binding, greatly improving the d

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.

In spring JDBC Development, you can use the JdbcTemplate and Jdbcdaosupport classes to simplify the operation of the entire database. In this tutorial, we will repeat the previous article Spring+jdbc example, looking at a different example between previous (no JdbcTemplate support) and later (with support for
