spring set-数组注入

还是举例说明：

QianDaye类

public class QianDaYe {
    private String[] aiHaos;

    //多个女性朋友
    private Woman[] womens;

    public void setAiHaos(String[] aiHaos) {
        this.aiHaos = aiHaos;
    }

    public void setWomens(Woman[] womens) {
        this.womens = womens;
    }

    @Override
    public String toString() {
        return "QianDaYe{" +
                "aiHaos=" + Arrays.toString(aiHaos) +
                ", womens=" + Arrays.toString(womens) +
                '}';
    }
}

Woman类

public class Woman {
    private String name;

    @Override
    public String toString() {
        return "Woman{" +
                "name='" + name + '\'' +
                '}';
    }

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

配置类spring-array.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">

    <bean id="w1" class="per.sxhzs.spring6.bean.Woman">
        <property name="name" value="小花"/>
    </bean>

    <bean id="w2" class="per.sxhzs.spring6.bean.Woman">
        <property name="name" value="小亮"/>
    </bean>

    <bean id="w3" class="per.sxhzs.spring6.bean.Woman">
        <property name="name" value="小明"/>
    </bean>

    <bean id="yuQian" class="per.sxhzs.spring6.bean.QianDaYe">
        <!--这个数组属性当中的元素类型是String简单类型-->
        <property name="aiHaos">
            <array>
                <value>抽烟</value>
                <value>喝酒</value>
                <value>烫头</value>
            </array>
        </property>

        <!--这个数组当中的类型就不是简单类型了。-->
        <property name="womens">
            <array>
                <ref bean="w1"/>
                <ref bean="w2"/>
                <ref bean="w3"/>
            </array>
        </property>

    </bean>
</beans>

测试类

@Test
    public void testArray() {
        ApplicationContext applicationContext = new ClassPathXmlApplicationContext("spring-array.xml");
        QianDaYe yuQian = applicationContext.getBean("yuQian", QianDaYe.class);
        System.out.println(yuQian);
    }
