Spring Bean的初始化和销毁方法一：通过设置bean的initMethod和destroyMethod属性指定初始化和销毁方法。

1、pom.xml

<dependencies>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-context</artifactId>
        <version>5.0.6.RELEASE</version>
    </dependency>
    <dependency>
        <groupId>org.projectlombok</groupId>
        <artifactId>lombok</artifactId>
        <version>1.18.2</version>
    </dependency>
</dependencies>

2、实体类

public class Car {
    public Car () {
        System.out.println("car constructor...");
    }

    public void init () {
        System.out.println("car init...");
    }

    public void destory () {
        System.out.println("car destory");
    }
}

3、配置类

import com.it.huaxin.vo.Car;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class LifeCycleConfig {
    @Bean(initMethod = "init", destroyMethod = "destory")
    public Car car() {
        return new Car();
    }
}

4、测试类

import com.it.huaxin.config.LifeCycleConfig;
import org.springframework.context.annotation.AnnotationConfigApplicationContext;

public class LifeCycleTest {
    public static void main(String [] args) {
        AnnotationConfigApplicationContext context = new AnnotationConfigApplicationContext(LifeCycleConfig.class);
    }
}

//结果

car constructor...
car init...
car destory...
