新增配置文件信息

# Mysql 1
mysql.datasource.test.url = jdbc:mysql://localhost:3306/test01?useUnicode=true&characterEncoding=utf-8
mysql.datasource.test.username = root
mysql.datasource.test.password = root

mysql.datasource.test.minPoolSize = 3
mysql.datasource.test.maxPoolSize = 25
mysql.datasource.test.maxLifetime = 20000
mysql.datasource.test.borrowConnectionTimeout = 30
mysql.datasource.test.loginTimeout = 30
mysql.datasource.test.maintenanceInterval = 60
mysql.datasource.test.maxIdleTime = 60
mysql.datasource.test.testQuery = select 1


# Mysql 2
mysql.datasource.test2.url =jdbc:mysql://localhost:3306/test02?useUnicode=true&characterEncoding=utf-8
mysql.datasource.test2.username =root
mysql.datasource.test2.password =root

mysql.datasource.test2.minPoolSize = 3
mysql.datasource.test2.maxPoolSize = 25
mysql.datasource.test2.maxLifetime = 20000
mysql.datasource.test2.borrowConnectionTimeout = 30
mysql.datasource.test2.loginTimeout = 30

读取配置文件信息

package com.itmayiedu.config;

import org.springframework.boot.context.properties.ConfigurationProperties;

@ConfigurationProperties(prefix = "mysql.datasource.test")
public class DBConfig1 {

	private String url;
	private String username;
	private String password;
	private int minPoolSize;
	private int maxPoolSize;
	private int maxLifetime;
	private int borrowConnectionTimeout;
	private int loginTimeout;
	private int maintenanceInterval;
	private int maxIdleTime;
	private String testQuery;
}
package com.itmayiedu.config;

import org.springframework.boot.context.properties.ConfigurationProperties;

@ConfigurationProperties(prefix = "mysql.datasource.test1")
public class DBConfig2 {

	private String url;
	private String username;
	private String password;
	private int minPoolSize;
	private int maxPoolSize;
	private int maxLifetime;
	private int borrowConnectionTimeout;
	private int loginTimeout;
	private int maintenanceInterval;
	private int maxIdleTime;
	private String testQuery;
}

创建多数据源

启动加载配置

@EnableConfigurationProperties(value = { DBConfig1.class, DBConfig2.class })
