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

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
