Spring普通属性的注入

Spring普通属性的注入

 

JavaBean代码，需要被注入的Bean：

package com.cos.entity;

import java.util.List;
import java.util.Map;
import java.util.Set;

public class UserBean {

    private String name;
    private int age;
    private String[] phone;
    private Map<String, String> son;
    private List store;
    private Set school;

    public Set getSchool() {
        return school;
    }
    public void setSchool(Set school) {
        this.school = school;
    }
    public List getStore() {
        return store;
    }
    public void setStore(List store) {
        this.store = store;
    }
    public Map<String, String> getSon() {
        return son;
    }
    public void setSon(Map<String, String> son) {
        this.son = son;
    }
    public int getAge() {
        return age;
    }
    public void setAge(int age) {
        this.age = age;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public String[] getPhone() {
        return phone;
    }
    public void setPhone(String[] phone) {
        this.phone = phone;
    }
}

 

 

Spring 配置文件 applicationContext.xml ，配置需要注入的Bean

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:jdbc="http://www.springframework.org/schema/jdbc"
	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
		http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc-3.0.xsd">

    <!-- 普通属性注入 -->
    <bean id="userBean" class="com.cos.entity.UserBean">
        <!-- String -->
        <property name="name" value="zhangsan"/>
        <!-- int -->
        <property name="age" value="20"/>
        <!-- 数组 -->
        <property name="phone">
            <list>
                <value>13817337235</value>
                <value>88025222</value>
            </list>
        </property>
        <!-- Map -->
        <property name="son">
            <map>
                <entry key="first" value="son1"/>
                <entry key="secend" value="son2"/>
            </map>
        </property>
        <!-- List -->
        <property name="store">
            <list>
                <value>store1</value>
                <value>store2</value>
            </list>
        </property>
        <!-- Set -->
        <property name="school">
            <set>
                <value>school1</value>
                <value>school2</value>
            </set>
        </property>
    </bean>

</beans>

 

其中JavaBean里面的属性名和xml文件中的property的name应保持一致。

 

测试类：

package com.cos.entity;

import org.springframework.beans.factory.BeanFactory;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class Main {

    public static void main(String[] args) {
        //通过spring配置文件返回Bean的工厂对象
        BeanFactory factory = new ClassPathXmlApplicationContext("applicationContext.xml");
        //Bean工厂通过Bean的id得到JavaBean
        UserBean ub = (UserBean) factory.getBean("userBean");
        System.out.println(""+ub.getName());
        System.out.println(""+ub.getAge());
        System.out.println(""+ub.getPhone());
        System.out.println(""+ub.getSon());
        System.out.println(""+ub.getStore());
        System.out.println(""+ub.getSchool());
    }
}
