set注入

顾名思义set注入必须要有set方法。

基本类型的注入、引用类型注入、List注入、Set注入、Map注入、Properties注入

public class person {
    private car c;
    private pay p;
    private List list;
    private Set set;
    private Map map;
    private Properties prop;
    
    public List getList() {
        return list;
    }
    public void setList(List list) {
        this.list = list;
    }
    public Set getSet() {
        return set;
    }
    public void setSet(Set set) {
        this.set = set;
    }
    public Map getMap() {
        return map;
    }
    public void setMap(Map map) {
        this.map = map;
    }
    public Properties getProp() {
        return prop;
    }
    public void setProp(Properties prop) {
        this.prop = prop;
    }
    public car getC() {
        return c;
    }
    public void setC(car c) {
        this.c = c;
    }
    public pay getP() {
        return p;
    }
    public void setP(pay p) {
        this.p = p;
    }
    @Override
    public String toString() {
        return "person [c=" + c + ", p=" + p + ", list=" + list + ", set="
                + set + ", map=" + map + ", prop=" + prop + "]";
    }
    
    
}

XML：

<!-- 要先创建引用类型的对象 -->
<bean id="car" class="DI.car"></bean>
<bean id="pay" class="DI.pay"></bean>

<bean id="person" class="DI.person">
    <!-- name 是有set方法猜测出的结果 ，ref是上面bean的id值 -->
    <property name="c" ref="car"></property>
    <property name="p" ref="pay"></property>
    <property name="list">
        <list>
            <value>啊啊啊啊啊</value>
            <value>啊啊啊啊啊1</value>
            <value>啊啊啊啊啊2</value>
        </list>
    </property>
    <property name="map">
        <map>
            <entry key="1" value="我"></entry>
            <entry key="2" value="你"></entry>
            <entry key="3" value="她"></entry>
        </map>
    </property>
    <property name="set">
        <set>
            <value>java</value>
            <value>javaaaaaaaaaa</value>
            <value>java</value>
        </set>
    </property>
    <property name="prop">
        <props>
            <prop key="1">我们</prop>
            <prop key="2">你们</prop>
            <prop key="3">她们</prop>
        </props>
    </property>
</bean>

测试类：

@Test
    public void test(){
        
        ApplicationContext cont = new ClassPathXmlApplicationContext("applicationContext.xml");
        person p = (person) cont.getBean("person");
        System.out.println(p);
    }

结果：
