    二:配置类

    package com.lc.collection;  
      
    import java.util.List;  
    import java.util.Map;  
    import java.util.Properties;  
    import java.util.Set;  
      
    public class Department {  
      
        private String name;  
        private String [] empName;//数组  
        private List<Employee> empList;//list集合  
        private Set<Employee> empsets;//set集合  
        private Map<String,Employee> empMaps;//map集合  
        private Properties pp;//Properties的使用  
      
          
        public Set<Employee> getEmpsets() {  
            return empsets;  
        }  
        public void setEmpsets(Set<Employee> empsets) {  
            this.empsets = empsets;  
        }  
        public String[] getEmpName() {  
            return empName;  
        }  
        public void setEmpName(String[] empName) {  
            this.empName = empName;  
        }  
        public String getName() {  
            return name;  
        }  
        public void setName(String name) {  
            this.name = name;  
        }  
        public List<Employee> getEmpList() {  
            return empList;  
        }  
        public void setEmpList(List<Employee> empList) {  
            this.empList = empList;  
        }  
        public Map<String, Employee> getEmpMaps() {  
            return empMaps;  
        }  
        public void setEmpMaps(Map<String, Employee> empMaps) {  
            this.empMaps = empMaps;  
        }  
        public Properties getPp() {  
            return pp;  
        }  
        public void setPp(Properties pp) {  
            this.pp = pp;  
        }  
      
    }  

    三:xml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"  
            xmlns:context="http://www.springframework.org/schema/context"  
            xmlns:tx="http://www.springframework.org/schema/tx"  
            xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd  
                    http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd  
                    http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd">  
      
    <bean id="department" class="com.hsp.collection.Department">  
    <property name="name" value="财务部"/>  
      
    <!-- 给数组注入值 -->  
    <property name="empName">  
        <list>  
            <value>小明</value>  
            <value>小明小明</value>  
            <value>小明小明小明小明</value>  
        </list>  
    </property>  
      
    <!-- 给list注入值 list 中可以有相当的对象 -->  
    <property name="empList">  
        <list>  
            <ref bean="emp2" />  
            <ref bean="emp1"/>  
            <ref bean="emp1"/>  
            <ref bean="emp1"/>  
            <ref bean="emp1"/>  
            <ref bean="emp1"/>  
            <ref bean="emp1"/>  
        </list>  
    </property>  
      
    <!-- 给set注入值 set不能有相同的对象 -->  
    <property name="empsets">  
        <set>  
            <ref bean="emp1" />  
            <ref bean="emp2"/>  
            <ref bean="emp2"/>  
            <ref bean="emp2"/>  
            <ref bean="emp2"/>  
        </set>  
    </property>  
      
    <!-- 给map注入值 map只有key不一样,就可以装配value -->  
    <property name="empMaps">  
        <map>  
            <entry key="11" value-ref="emp1" />   
            <entry key="22" value-ref="emp2"/>  
            <entry key="22" value-ref="emp1"/>  
        </map>  
    </property>  
      
    <!-- 给属性集合配置 -->  
    <property name="pp">  
        <props>  
            <prop key="pp1">abcd</prop>  
            <prop key="pp2">hello</prop>  
        </props>  
    </property>  
    </bean>  
      
    <bean id="emp1" class="com.hsp.collection.Employee">  
        <property name="name" value="北京"/>  
        <property name="id" value="1"/>  
    </bean>  
    <bean id="emp2" class="com.hsp.collection.Employee">  
        <property name="name" value="天津"/>  
        <property name="id" value="2"/>  
    </bean>  
      
    </beans>
