JdbcTemplate found a problem when it was used:Call the queryForObject () method and throw an exception if nothing is found: org.springframework.dao.EmptyResultDataAccessException:Incorrect result size:expected 1, actual 0You do not want to throw this exception, but return to null on the line. See Source code @Override public The result set in the source code returns a static method that calls Dataaccessutils, and

We have been using the SSM framework to write Web sites that Access database types, and app,web sites need to have databases to store data. Let's take a look at the Springboot operation database using JdbcTemplate; data Source configuration in the configuration file When we access the database, we need to first configure a data source, the following describes several different ways of database configuration.

Using spring's own jdbctemplate, you can simplify the operation of the database, it is very convenient to use.

In the previous article, we talked about single data connection access, inserting data, but often as the traffic grows, we usually split the database or introduce other databases, so we need to configure multiple data sources, The configuration of two multi-data sources is described below, based on the previous jdbctemplate and SPRING-DATA-JPA examples.
