This guide will guide you through using the Leopard label to simplify Spring configuration.

How to complete this guide

You can start from scratch and complete each step, or you can bypass the basic setup steps you are already familiar. Either way, you can finally get the code that can work.

1. XML file header configuration

The Leopard label is a configuration method based on XML Schema. It aims to simplify the configuration method. Add the following content to the XML file header:
Xmlns: leopard = "http://www.leopard.io/schema/leopard.pdf ".
Xsi: schemaLocation = http://www.leopard.io/schema/leopard http://www.leopard.io/schema/leopard.xsd"

2. <leopard: component-scan/>

Similar By default, the Bean name rule defined by Leopard is used, and the timer is automatically registered (Bean that implements the io. leopard. burrow. Timer. timer interface ).

Example

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:leopard="http://www.leopard.io/schema/leopard"    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd    http://www.leopard.io/schema/leopard http://www.leopard.io/schema/leopard.xsd">    <leopard:component-scan base-package="io.leopard.guides" /></beans>

Parameter description
base-package: Spring Bean package path

3. <leopard: jdbc/>

MySQL Data Source definition.

Example

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:leopard="http://www.leopard.io/schema/leopard"    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd    http://www.leopard.io/schema/leopard http://www.leopard.io/schema/leopard.xsd">    <leopard:jdbc id="jdbc" host="112.126.75.27" database="example" user="example" password="leopard" /></beans>

Parameter description
id: Bean name. We recommend that you use id = "jdbc" when there is only one database, and use database name + "Jdbc" when there are multiple databases"
host: The host or IP address of the MySQL server. placeholders can also be used.
database: Database Name
user: Database username
password: Database Password
port: Database port. The default value is 3306.
maxPoolSize: Maximum number of connections in the connection pool. The default value is 15.
dataSourceId: DataSource Bean name. <leopard: jdbc/> A DataSource Bean is automatically created and can be used for other purposes. The default name is jdbcId + "DataSource ".

4. <leopard: redis/>

Redis Data Source definition.

Example

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:leopard="http://www.leopard.io/schema/leopard"    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd    http://www.leopard.io/schema/leopard http://www.leopard.io/schema/leopard.xsd">    <leopard:redis id="redis" server="112.126.75.27:6311" /></beans>

Parameter description
id: Bean name
server: MySQL server host (IP) + port, for example, "112.126.75.27: 6311"
maxActive: Maximum number of connections in the connection pool. The default value is 128.
timeout: Timeout time, in milliseconds. The default value is 3000 milliseconds.
initialPoolSize: The default number of initialized connections in the connection pool. The default value is 1.
enableBackup: Whether to enable automatic backup (that is, run bgsave to save the data). By default, automatic backup is disabled.
backupTime: Backup time, in the format of "mm: hh". The default value is 04:01. (Backup starts at every day)

Summary

Congratulations! You have learned to use the Leopard label to simplify Spring configurations. Good luck.
