spring set-简单类型注入

举例说明：

Clazz类

package per.sxhzs.spring6.bean;

/**
 * 表示班级
 */
public class Clazz {
    private String name;

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

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

Season接口

package per.sxhzs.spring6.bean;

public enum Season {
    SPRING, SUMMER, AUTUMN, WINTER
}

SimpleValueType类

package per.sxhzs.spring6.bean;

import java.util.Date;

public class SimpleValueType {
    /*
    public static boolean isSimpleValueType(Class<?> type) {
		return (Void.class != type && void.class != type &&
				(ClassUtils.isPrimitiveOrWrapper(type) ||
				Enum.class.isAssignableFrom(type) ||
				CharSequence.class.isAssignableFrom(type) ||
				Number.class.isAssignableFrom(type) ||
				Date.class.isAssignableFrom(type) ||        java.util.Date是简单类型
				Temporal.class.isAssignableFrom(type) ||    Temporal是Java8提供的时间和时区类型
				URI.class == type ||
				URL.class == type ||
				Locale.class == type ||                     Locale是语言类，也是简单类型。
				Class.class == type));
	}

    }

配置类

<!--测试那些类型是简单类型-->
    <bean id="svt" class="per.sxhzs.spring6.bean.SimpleValueType">
        <property name="season" value="SPRING"/>
        <property name="username" value="张三"/>
        <property name="age" value="18"/>
        <property name="age2" value="20"/>
        <property name="flag" value="false"/>
        <property name="flag2" value="true"/>
        <property name="c" value="男"/>
        <property name="c2" value="女"/>
        <property name="clazz" value="java.lang.String"/>
        <!--报错了，说这个"2002-02-09"字符串无法转换成Java.util.Date-->
<!--        <property name="birth" value="2002-02-09"/>-->
        <!--如果要把Date当作简单类型，使用value赋值的话，这个日期字符串格式有要求。-->
        <!--在实际开发中，我们一般不会把Date当作简单类型，虽然他是简单类型。一般会采用ref给Date类型的属性赋值。-->
        <property name="birth" value="Sat Nov 12 19:37:40 CST 2022"/>
    </bean>

测试类

@Test
    public void testSimpleTypeSet() {
        ApplicationContext applicationContext = new ClassPathXmlApplicationContext("set-di.xml");
//        User user = applicationContext.getBean("userBean", User.class);
//        System.out.println(user);

        SimpleValueType svt = applicationContext.getBean("svt", SimpleValueType.class);
        System.out.println(svt);
    }

运行结果
