Spring set注入-蒲公英云

Spring set注入

通过set方法进行属性的注入

#

一、新建类

首先建一个普通类，定义属性，并生成相应的set方法

Book.java

/**
 * set方法进行注入
 */
public class Book {
    private String bname;
    private String bauthor;
    public void setBname(String bname) {
        this.bname = bname;
    }
    public void setBauthor(String bauthor) {
        this.bauthor = bauthor;
    }
    public void testDemo(){
        System.out.println(bname+"    "+bauthor);
    }
}

#

二、编写配置文件

在配置文件中配置对象创建并进行属性注入

bean2.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"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">
    <!--1.配置Book对象创建-->
    <bean id="book" class="com.health.IOC.B_set注入.Book">
        <!--2.set方法注入属性-->
        <property name="bname" value="围城"/>
        <property name="bauthor" value="钱钟书"/>
    </bean>
</beans>

#

三、测试

test02.java

public class test02 {
    public static void main(String[] args) {
        ApplicationContext context =
                new ClassPathXmlApplicationContext("com/health/IOC/B_set注入/bean2.xml");
        Book book = context.getBean("book",Book.class);
        book.testDemo();
    }
}
