Spring中构建BeanDefinition的两种方法

• BeanDefinitionBuilder
• GenericBeanDefinition

RumenzA.class

package com.rumenz;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

import javax.annotation.PostConstruct;

public class RumenzA {

    private String id;
    private String name;

    public String getId() {return id;}

    public void setId(String id) {this.id = id;}

    public String getName() {return name;}

    public void setName(String name) {this.name = name;}

    public  RumenzA() {System.out.println("RumenzA 无参构造方法");
    }
}

BeanDefinitionBuilder

 //1. 通过 BeanDefinitionBuilder
 BeanDefinitionBuilder bdb=BeanDefinitionBuilder.genericBeanDefinition(RumenzA.class);
 // 设置属性
 bdb.addPropertyValue("id",1).addPropertyValue("name","入门小站");
 // 获取 BeanDefinition
 BeanDefinition bd=bdb.getBeanDefinition();
 // 后期的 BeanDefinition 还是可以修改的
 System.out.println(bd);
 

GenericBeanDefinition

 //2. 通过 GenericBeanDefinition
 GenericBeanDefinition gb= new GenericBeanDefinition();
 // 设置 bean
 gb.setBeanClass(RumenzA.class);
 // 设置属性
 MutablePropertyValues mp=new MutablePropertyValues();
 mp.add("id",1).add("name","入门小站");
 gb.setPropertyValues(mp);
 System.out.println(gb);
