1.P名称空间注入（少用）：

代码很简单：

public class SteClass {
    
    	private String nameSet;
    
    	public void setNameSet(String nameSet) {
    		this.nameSet = nameSet;
    	}
    	public void testSet(){
    		System.out.println("setTest===="+nameSet);
    	}
    	
    }

xmlns:p="http://www.springframework.org/schema/p"

@Test
    	public void test4(){
    		ApplicationContext con=new ClassPathXmlApplicationContext("mapper/spring.xml");
    		SteClass us=(SteClass) con.getBean("name");
    		us.testSet();
    	}

2. 数组：

3. list集合：

4.map集合：

5.properties 《键值对》类型：

代码如下

public class Person {
    
    	private String[]arras;
    	private  List<String> list;
    	private Map<String,String> map;
    	private Properties properties;
    	public void setArras(String[] arras) {
    		this.arras = arras;
    	}
    	
    	public void setList(List<String> list) {
    		this.list = list;
    	}
    	
    	public void setMap(Map<String, String> map) {
    		this.map = map;
    	}
    	
    	public void setProperties(Properties properties) {
    		this.properties = properties;
    	}
    	
    	public void test1(){
    		System.out.println("arras=="+arras);
    		System.out.println("arras=="+arras[0]);
    		System.out.println("map=="+map);
    		System.out.println("list=="+list);
    		System.out.println("properties=="+properties);
    	}

<bean id="persion" class="ioc.Person">
           
           <property name="arras" >
              <list>
                <value>小谢</value>
                <value>小猫</value>
                <value>小猪</value>
                <value>小狗</value>
              </list>
           </property>
           
           <property name="list" >
              <list>
                <value>老谢</value>
                <value>老猫</value>
                <value>老猪</value>
                <value>老狗</value>
              </list>
           </property>
           
           <property name="map" >
             <map>
               <entry key="1" value="小鸡"></entry>
               <entry key="2" value="小谢"></entry>
               <entry key="3" value="小鸭"></entry>
               <entry key="4" value="小虫"></entry>
             </map>
           </property>
           
           
              <property name="properties">
                 <props>
                    <prop key="driverclass">class.mysql.jdbc.Driver</prop>
                    <prop key="username">root</prop>
                 </props>
              </property>
           </bean>

@Test
    	public void test5(){
    		ApplicationContext con=new ClassPathXmlApplicationContext("mapper/spring.xml");
    		Person us=(Person) con.getBean("persion");
    		us.test1();
    		
    	}
