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);
