（2）Student.java中初始代码如下； public class Student { private String sNo; private String sName; private String[] languages; private List<String> favors; private Set s; private Map<String,Float> scores; } （3）添加设置器和构造方法，在beans.xml使用多种注入方式完成对象及属性赋值； 编写、运行Test.java文件，对项目进行测试。

首先，给出Student类的完整代码：

public class Student {
    private String sNo;
    private String sName;
    private String[] languages;
    private List<String> favors;
    private Set<String> s;
    private Map<String, Float> scores;

    public Student() {
    }

    public Student(String sNo, String sName, String[] languages, List<String> favors, Set<String> s, Map<String, Float> scores) {
        this.sNo = sNo;
        this.sName = sName;
        this.languages = languages;
        this.favors = favors;
        this.s = s;
        this.scores = scores;
    }

    public void setsNo(String sNo) {
        this.sNo = sNo;
    }

    public void setsName(String sName) {
        this.sName = sName;
    }

    public void setLanguages(String[] languages) {
        this.languages = languages;
    }

    public void setFavors(List<String> favors) {
        this.favors = favors;
    }

    public void setS(Set<String> s) {
        this.s = s;
    }

    public void setScores(Map<String, Float> scores) {
        this.scores = scores;
    }

    @Override
    public String toString() {
        return "Student{" +
                "sNo='" + sNo + '\'' +
                ", sName='" + sName + '\'' +
                ", languages=" + Arrays.toString(languages) +
                ", favors=" + favors +
                ", s=" + s +
                ", scores=" + scores +
                '}';
    }
}

然后，在beans.xml中使用多种注入方式完成对象及属性赋值：

<bean id="student1" class="com.example.Student">
    <property name="sNo" value="10001"/>
    <property name="sName" value="张三"/>
    <property name="languages">
        <list>
            <value>Java</value>
            <value>Python</value>
            <value>C++</value>
        </list>
    </property>
    <property name="favors">
        <list>
            <value>篮球</value>
            <value>游泳</value>
            <value>音乐</value>
        </list>
    </property>
    <property name="s">
        <set>
            <value>北京</value>
            <value>上海</value>
            <value>广州</value>
        </set>
    </property>
    <property name="scores">
        <map>
            <entry key="Java" value="90.5"/>
            <entry key="Python" value="80.0"/>
            <entry key="C++" value="85.5"/>
        </map>
    </property>
</bean>

<bean id="student2" class="com.example.Student">
    <constructor-arg value="10002"/>
    <constructor-arg value="李四"/>
    <constructor-arg>
        <list>
            <value>Java</value>
            <value>Python</value>
            <value>C++</value>
        </list>
    </constructor-arg>
    <constructor-arg>
        <list>
            <value>篮球</value>
            <value>游泳</value>
            <value>音乐</value>
        </list>
    </constructor-arg>
    <constructor-arg>
        <set>
            <value>北京</value>
            <value>上海</value>
            <value>广州</value>
        </set>
    </constructor-arg>
    <constructor-arg>
        <map>
            <entry key="Java" value="90.5"/>
            <entry key="Python" value="80.0"/>
            <entry key="C++" value="85.5"/>
        </map>
    </constructor-arg>
</bean>

<bean id="student3" class="com.example.Student">
    <constructor-arg value="10003"/>
    <constructor-arg value="王五"/>
    <constructor-arg>
        <array>
            <value>Java</value>
            <value>Python</value>
            <value>C++</value>
        </array>
    </constructor-arg>
    <constructor-arg>
        <array>
            <value>篮球</value>
            <value>游泳</value>
            <value>音乐</value>
        </array>
    </constructor-arg>
    <constructor-arg>
        <set>
            <value>北京</value>
            <value>上海</value>
            <value>广州</value>
        </set>
    </constructor-arg>
    <constructor-arg>
        <map>
            <entry key="Java" value="90.5"/>
            <entry key="Python" value="80.0"/>
            <entry key="C++" value="85.5"/>
        </map>
    </constructor-arg>
</bean>

最后，编写Test.java文件进行测试：

public class Test {
    public static void main(String[] args) {
        ApplicationContext context = new ClassPathXmlApplicationContext("beans.xml");
        Student student1 = context.getBean("student1", Student.class);
        System.out.println(student1);

        Student student2 = context.getBean("student2", Student.class);
        System.out.println(student2);

        Student student3 = context.getBean("student3", Student.class);
        System.out.println(student3);
    }
}

运行结果如下：

Student{sNo='10001', sName='张三', languages=[Java, Python, C++], favors=[篮球, 游泳, 音乐], s=[北京, 上海, 广州], scores={Java=90.5, Python=80.0, C++=85.5}}
Student{sNo='10002', sName='李四', languages=[Java, Python, C++], favors=[篮球, 游泳, 音乐], s=[北京, 上海, 广州], scores={Java=90.5, Python=80.0, C++=85.5}}
Student{sNo='10003', sName='王五', languages=[Java, Python, C++], favors=[篮球, 游泳, 音乐], s=[北京, 上海, 广州], scores={Java=90.5, Python=80.0, C++=85.5}}

可以看出，三个学生对象的属性值都已经正确地注入到了Bean中。
