How to spring load multiple configuration profiles

Multiple profiles for specific applications:

More relational configuration file:

1. Juxtaposed
2. contain

Constellation

That there are multiple configuration files, which need to load multiple configuration files at the same time;

The variable parameters can be used, and an array of wildcards loaded;

1. variable parameter

String config1 = "com/abc/di08/spring-student.xml";
String config2 = "com/abc/di08/spring-school.xml";
//加载配置文件，生成spring容器对象（多个字符串参数加载多个配置文件）
ApplicationContext ac = new ClassPathXmlApplicationContext(config1,config2);

1. Load Array

String config1 = "com/abc/di08/spring-student.xml";
String config2 = "com/abc/di08/spring-school.xml";
String[] configs = {config1,config2};
//加载配置文件，生成spring容器对象（数组加载多个配置文件）
ApplicationContext ac = new ClassPathXmlApplicationContext(configs);

1. Wildcard load

    String config = "com/abc/di08/spring-*.xml";
    //加载配置文件，生成spring容器对象（通配符加载多个配置文件）
    ApplicationContext ac = new ClassPathXmlApplicationContext(config);

Inclusion relation

First, load the master configuration file, and then using wildcards load another profile in the main configuration file.

String config = "com/abc/di09/applicationContext.xml";
ApplicationContext ac = new ClassPathXmlApplicationContext(config);

<!--import标签加载包含配置文件-->
<import resource="spring-*.xml"/>
