10 recommended articles about parameter configuration

This article mainly introduces the relevant knowledge of .properties file reading and placeholder ${...} replacement source code analysis, which has a good reference value. Let’s take a look at it with the editor. Preface We often encounter a scenario in development. Some parameters in the Bean are relatively fixed. In this case, configuration is usually used to configure these parameters in the .properties file. Then when the Bean is instantiated, the parameters configured in these .properties files are read in and set to the corresponding parameters of the Bean by replacing the placeholder "${}" through Spring. The most typical example of this approach is JDBC configuration. This article will study the source code for reading .properties files and replacing placeholders "${}". First, start with the code, define a DataSource, and simulate the four parameters of JDBC: public class DataSource { /**

MySQL - A detailed introduction on how to add a new database to the MySQL master-slave replication list

##Introduction: MySQL master-slave replication Generally, we will set up the database that needs to be synchronized. Using parameter configuration options, binlog-do-db, you can specify the database that needs to be synchronized on the master. Replicate-do-db is used on the slave. The data looks at the specified database that needs to be synchronized. (Generally, only binlog-do-db on the master is set, and there is no need to set both at the same time. Just in case, you can also add replicate-ignore-db on the slave). Today, the problem I encountered is that on the master

Introduction: Summary: The default slow query time is 5 seconds, and queries exceeding 5 seconds are recorded. You can use set long_query_time = 2 to set the slow query time, and you can also use mysqldumpslow to analyze the slow query log. For example, to analyze the 20 most accessed statements, mysqldumpslow –s c –t 20 /usr/local/mysql/var /slowqu...
