Student实体类

package entity;import java.util.*;public class Student {    private int id;    private String name;    private StudentClass studentClass;    private String[] books;    private List<String> hobbies;    private Map<String, String> cards;    private Set<String> games;    private String wife;    private Properties info;    public int getId() {        return id;    }    public void setId(int id) {        this.id = id;    public String getName() {        return name;    public void setName(String name) {        this.name = name;    public StudentClass getStudentClass() {        return studentClass;    public void setStudentClass(StudentClass studentClass) {        this.studentClass = studentClass;    public String[] getBooks() {        return books;    public void setBooks(String[] books) {        this.books = books;    public List<String> getHobbies() {        return hobbies;    public void setHobbies(List<String> hobbies) {        this.hobbies = hobbies;    public Map<String, String> getCards() {        return cards;    public void setCards(Map<String, String> cards) {        this.cards = cards;    public Set<String> getGames() {        return games;    public void setGames(Set<String> games) {        this.games = games;    public String getWife() {        return wife;    public void setWife(String wife) {        this.wife = wife;    public Properties getInfo() {        return info;    public void setInfo(Properties info) {        this.info = info;    @Override    public String toString() {        return "Student{" +                "id=" + id +                ", name='" + name + '\'' +                ", studentClass=" + studentClass +                ", books=" + Arrays.toString(books) +                ", hobbies=" + hobbies +                ", cards=" + cards +                ", games=" + games +                ", wife='" + wife + '\'' +                ", info=" + info +                '}';}

StudentsClass实体类

package entity;public class StudentClass {    private int id;    private String name;    public int getId() {        return id;    }    public void setId(int id) {        this.id = id;    }    public String getName() {        return name;    }    public void setName(String name) {        this.name = name;    }    @Override    public String toString() {        return "Class{" +                "id=" + id +                ", name='" + name + '\'' +                '}';    }}

beans.xml

下面展示的数据类型有：一般类型、对象、数组、List、Map、Set、空值、Properties

<?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">    <bean id="studentClass1" class="entity.StudentClass">        <property name="id" value="1"/>        <property name="name" value="软件工程3班"/>    </bean>    <bean id="user1" class="entity.Student">        <!--一般类型-->        <property name="id" value="1"/>        <property name="name" value="tom"/>        <!--对象-->        <property name="studentClass" ref="studentClass1"/>        <!--数组-->        <property name="books">            <array>                <value>Java编程思想</value>                <value>MySQL必知必会</value>                <value>平凡的世界</value>            </array>        </property>        <!--List-->        <property name="hobbies">            <list>                <value>唱</value>                <value>跳</value>                <value>rap</value>                <value>打篮球</value>            </list>        </property>        <!--Map-->        <property name="cards">            <map>                <entry key="身份证" value="123"/>                <entry key="校园卡" value="321"/>            </map>        </property>        <!--Set-->        <property name="games">            <set>                <value>LOL</value>                <value>DNF</value>                <value>COC</value>            </set>        </property>        <!--空值-->        <property name="wife">            <null/>        </property>        <!--Properties-->        <property name="info">            <props>                <prop key="userName">root</prop>                <prop key="password">123456</prop>            </props>        </property>    </bean></beans>
