springboot引入外部xml配置文件

1、 resources下創建xml

<?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:context="http://www.springframework.org/schema/context"
      xsi:schemaLocation="http://www.springframework.org/schema/beans
      http://www.springframework.org/schema/beans/spring-beans-4.3.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">

   <!-- 採用註釋的方式配置bean -->
   <context:annotation-config />
   <!-- 配置要掃描的包 -->
   <context:component-scan base-package="com.xml"/>

   <!--<bean id="testBean" class="com.xml.TestBean"/>-->
</beans>

2、編寫配置類用於加載xml文件

package com.forezp.config;

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

@Configuration
@ImportResource(locations= {"classpath:root-bean.xml"})
public class XmlConfig {

}

3、 創建bean

/**
 * 用於加載xml
 */
@Component
public class TestBean {


    private String username;

    private String url;

    private String password;

    public TestBean() {
        System.out.println("這是一個不在springboot掃描範圍內的測試類");
        System.out.println("TestBean-----------------加載了---------------");
    }

    public void sayHello() {
        System.out.println("TestBean sayHello...");
    }


    public void start() {
        System.out.println("TestBean 初始化。。。");
    }

    public void cleanUp() {
        System.out.println("TestBean 銷燬。。。");
    }

}

4、 啓動項目即可加載
