c命名和p命名空间注入

配置文件需要导入的配置

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

创建实体类

public class user {
    private String name;
    private int age;
 
    public user(String name, int age) {
        this.name = name;
        this.age = age;
    }
 
    public user() {
    }
 
    public String getName() {
        return name;
    }
 
    public void setName(String name) {
        this.name = name;
    }
 
    public int getAge() {
        return age;
    }
 
    public void setAge(int age) {
        this.age = age;
    }
 
    @Override
    public String toString() {
        return "user{" +
                "name='" + name + '\'' +
                ", age=" + age +
                '}';
    }
}

配置文件

<!--p命名空间，用于普通的一般属性注入-->
    <bean id="user" class="com.Google.pojo.user" p:age="19" p:name="Spring"/>
 
    <!--c命名空间，用于构造函数注入-->
    <bean id="user1" class="com.Google.pojo.user" c:age="20" c:name="Spring1"/>

实现

@Test
    public  void test(){
        ApplicationContext context = new ClassPathXmlApplicationContext("userBeans.xml");
        user user = context.getBean("user", user.class);
        System.out.println(user);
    }
