Spring3 JavaConfig它等效于 @Import 功能

package com.yiibai.config;

import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Import;

@Configuration
@Import({ CustomerConfig.class, SchedulerConfig.class })
public class AppConfig {

}

@Import實(shí)例

請(qǐng)參閱使用JavaConfig @Import的一個(gè)完整的例子。

1. 目錄結(jié)構(gòu)

本實(shí)例目錄結(jié)構(gòu)。

2. Spring Beans

兩個(gè)簡(jiǎn)單的Spring bean。

File : CustomerBo.java

package com.yiibai.core;

public class CustomerBo {

	public void printMsg(String msg) {

		System.out.println("CustomerBo : " + msg);
	}

}

File : SchedulerBo.java

package com.yiibai.core;

public class SchedulerBo {

	public void printMsg(String msg) {

		System.out.println("SchedulerBo : " + msg);
	}

}

3. @Configuration示例

現(xiàn)在，使用JavaConfig @Configuration聲明上述Bean類。

File : CustomerConfig.java

package com.yiibai.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import com.yiibai.core.CustomerBo;

@Configuration
public class CustomerConfig {
	
	@Bean(name="customer")
	public CustomerBo customerBo(){
		
		return new CustomerBo();
		
	}
}

File : SchedulerConfig.java

package com.yiibai.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import com.yiibai.core.SchedulerBo;

@Configuration
public class SchedulerConfig {
	
	@Bean(name="scheduler")
	public SchedulerBo suchedulerBo(){
		
		return new SchedulerBo();
		
	}
	
}

4. @Import示例

使用@Import加載多個(gè)配置文件。

File : AppConfig.java

package com.yiibai.config;

import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Import;

@Configuration
@Import({ CustomerConfig.class, SchedulerConfig.class })
public class AppConfig {

}

5. 執(zhí)行程序

加載主配置文件，并進(jìn)行測(cè)試。

package com.yiibai.core;

import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.AnnotationConfigApplicationContext;
import com.yiibai.config.AppConfig;

public class App {
	public static void main(String[] args) {

		ApplicationContext context = new AnnotationConfigApplicationContext(
				AppConfig.class);

		CustomerBo customer = (CustomerBo) context.getBean("customer");
		customer.printMsg("Hello 11");

		SchedulerBo scheduler = (SchedulerBo) context.getBean("scheduler");
		scheduler.printMsg("Hello 22");

	}
}

輸出結(jié)果

CustomerBo : Hello 11
SchedulerBo : Hello 22
