Spring框架xml配置文件 复杂类型属性注入——数组 list map properties

Person类中的各种属性写法如下：

package com.swift.person;

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

public class Person {　　//普通字符串
    private String name;　　//字符串数组
    private String[] arr;　　//字符串列表
    private List<String> list;　　//键值对都为字符串的地图
    private Map<String,String> map;
    public void setMap(Map<String, String> map) {
        this.map = map;
    }　　//这还有一个键值对的属性类
    private Properties properties;
    public void setName(String name) {
        this.name = name;
    }
    public void setArr(String[] arr) {
        this.arr = arr;
    }
    public void setList(List<String> list) {
        this.list = list;
    }
    public void setProperties(Properties properties) {
        this.properties = properties;
    }
    public String fun() {
        return "Person [name=" + name + ", arr=" + Arrays.toString(arr) + ", list=" + list + ", map=" + map
                + ", properties=" + properties + "]";
    }
}

在xml配置文件中按如下方式配置：

<?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">
<!-- IoC 控制反转 Spring根据XML配置文件注入复杂类型属性 -->
<bean id="person" class="com.swift.person.Person">
<property name="name" value="swift"></property>
<property name="arr">
<list>
<value>西施</value>
<value>貂蝉</value>
<value>王昭君</value>
<value>杨玉环</value>
</list>
</property>
<property name="list">
<list>
<value>汪精卫</value>
<value>周恩来</value>
<value>梅兰芳</value>
<value>张学良</value>
</list>
</property>
<property name="map">
<map>
<entry key="name" value="swift"></entry>
<entry key="profession" value="programmer"></entry>
<entry key="city" value="beijing"></entry>
</map>
</property>
<property name="properties">
<props>
<prop key="1">冬天里的一把火</prop>
<prop key="2">逆流成河</prop>
<prop key="3">男儿当自强</prop>
</props>
</property>
</bean>
</beans>

调用的实现类如下：

package com.swift.servlet;

import java.io.IOException;

import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

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

import com.swift.person.Person;
@WebServlet("/person")
public class ServletPerson extends HttpServlet {
    private static final long serialVersionUID = 1L;
    public ServletPerson() {
        super();
    }
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        response.setCharacterEncoding("utf-8");
        response.setContentType("text/html;charset=utf-8");
        response.getWriter().append("Served at: ").append(request.getContextPath());
        ApplicationContext context=new ClassPathXmlApplicationContext("context.xml");
        Person per=(Person) context.getBean("person");
        String personInfo=per.fun();
        response.getWriter().append(personInfo);
    }
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        doGet(request, response);
    }

}
