spring注入不同数据类型

spring注入不同数据类型

1.先来个实体类，里面包含各种数据类型，其他代码参考spring框架IOC设值注入

package com.domain;

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

/**
 * 
 * @author Mr
 * 各种各样的数据类型
 */
public class TestEntity {
    //特殊的类型1
    private String specialCharacter1;
    //特殊的类型2
    private String specialCharacter2;
    //javaBean类型
    private User innerBean;
    //List类型
    private List<String> list;
    //数组类型
    private String [] array;
    //Set集合类型
    private Set<String> set;
    //Map类型
    private Map<String, String> map;
    //properties
    private Properties props;
    //空字符串
    private String emptyValue;
    //空字符串
    private String nullValue="init value";
    public String getSpecialCharacter1() {
        return specialCharacter1;
    }
    public void setSpecialCharacter1(String specialCharacter1) {
        this.specialCharacter1 = specialCharacter1;
    }
    public String getSpecialCharacter2() {
        return specialCharacter2;
    }
    public void setSpecialCharacter2(String specialCharacter2) {
        this.specialCharacter2 = specialCharacter2;
    }
    public User getInnerBean() {
        return innerBean;
    }
    public void setInnerBean(User innerBean) {
        this.innerBean = innerBean;
    }
    public List<String> getList() {
        return list;
    }
    public void setList(List<String> list) {
        this.list = list;
    }
    public String[] getArray() {
        return array;
    }
    public void setArray(String[] array) {
        this.array = array;
    }
    public Set<String> getSet() {
        return set;
    }
    public void setSet(Set<String> set) {
        this.set = set;
    }
    public Map<String, String> getMap() {
        return map;
    }
    public void setMap(Map<String, String> map) {
        this.map = map;
    }
    public Properties getProps() {
        return props;
    }
    public void setProps(Properties props) {
        this.props = props;
    }
    public String getEmptyValue() {
        return emptyValue;
    }
    public void setEmptyValue(String emptyValue) {
        this.emptyValue = emptyValue;
    }
    public String getNullValue() {
        return nullValue;
    }
    public void setNullValue(String nullValue) {
        this.nullValue = nullValue;
    }
    
    //来个方法显示相关
    public void showValue(){
        
        System.out.println("特殊的类型1:"+this.specialCharacter1);
        System.out.println("特殊的类型1:"+this.specialCharacter2);
        System.out.println("javaBean类型:"+this.innerBean.getUname());
        System.out.println("List类型:"+this.list);
        System.out.println("数组类型:"+this.array[0]);
        System.out.println("Set集合类型:"+this.set);
        System.out.println("Map类型:"+this.map);
        System.out.println("properties类型:"+this.props);
        System.out.println("空字符串类型:"+this.emptyValue);
        System.out.println("空字符串类型:"+this.nullValue);
    }
    
}

2.写spring配置文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:p="http://www.springframework.org/schema/p"
    xmlns:aop="http://www.springframework.org/schema/aop"
    xsi:schemaLocation="http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.1.xsd
        http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd">
    <!-- 各种各样的数据类型 -->
    <bean id="entitys" class="com.domain.TestEntity">
        <!-- 特殊的类型1 -->
        <property name="specialCharacter1">
            <value><![CDATA[P&G]]></value>
        </property>
        <!-- 特殊的类型2 -->
        <property name="specialCharacter2">
            <value>P&amp;G</value>
        </property>
        <!-- 实体类 -->
        <property name="innerBean">
            <!-- 不要写id 但要写class-->
            <bean class="com.domain.User">
                <property name="uname">
                    <value>张三丰</value>
                </property>
            </bean>
        </property>
        <!-- list类型 -->
        <property name="list">
            <list>
            <value>乒乓球</value>
            <value>排球球</value>
            <value>羽毛球</value>
            </list>
        </property>
        <!-- 数组类型 -->
        <property name="array">
            <list>
            <value>苹果</value>
            <value>香蕉</value>
            </list>
        </property>
        <!-- Set集合类型 -->
        <property name="set">
        <list>
            <value>电视机</value>
            <value>冰柜</value>
        </list>
        </property>
        <!-- Map类型  键值对的形式-->
        <property name="map">
            <map>
                <entry>
                    <key>
                    <!-- 这是key的名字 -->
                        <value>football</value>
                    </key>
                    <!-- 这是key对应的值 -->
                    <value>足球</value>
                </entry>
                <entry>
                    <key>
                        <value>basketball</value>
                    </key>
                    <value>蓝球</value>
                </entry>
            </map>
        </property>
        <!-- properties -->
        <property name="props">
        <props>
            <prop key="beijing">北京</prop>
            <prop key="shanghai">上海</prop>
        </props>
        </property>
        <!-- 空字符串  返回空 没有任何东西-->
        <property name="emptyValue">
            <value></value>
        </property>
        <!-- 空字符串 返回null -->
        <property name="nullValue">
        <null></null>
        </property>
    </bean>
    
    
    
</beans>

3.写测试类

package com.test;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.biz.IUserBiz;
import com.domain.TestEntity;
import com.domain.User;

/**
 * 
 * @author Mr
 * aop测试类
 */
public class Test {

    public static void main(String[] args) {
        //解析配置文件
        ApplicationContext ac = new ClassPathXmlApplicationContext("applicationContext.xml");
        
        TestEntity te = (TestEntity) ac.getBean("entitys");
        te.showValue();
    }

}

4.效果图
