spring配置Dem

   

    一。在eclipse新建项目，导入jar包

     

 二 在XML内的配置

   <context-param>
   <param-name>contextConfigLocation</param-name>

    //或都 这样 <param-value>classpath*:config/spring*.xml</param-value>
   <param-value>classpath:</param-value>
  </context-param>
  <listener>
   <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>

  三。创建一个bean

     public class UserDemo {


private int id;
private String name;
public UserDemo(int id, String name) {
super();
this.id = id;
this.name = name;
}
public UserDemo() {
super();
// TODO Auto-generated constructor stub
}
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;
}

}

四。在applicationContext.xml下的写法

    <?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:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:aop="http://www.springframework.org/schema/aop"    xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd 
http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd 
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd">

 <bean id="user" class="test.UserDemo">
  <property name="id" value="12"></property>
   <property name="name" value="name"></property>
 </bean>
</beans> 

  五 测试连接是否成功

      import org.junit.Test;
    import org.springframework.context.ApplicationContext;
    import org.springframework.context.support.ClassPathXmlApplicationContext;


    public class test {


private ApplicationContext ac=new ClassPathXmlApplicationContext("applicationContext.xml");
 
@Test
public  void test(){
UserDemo userDemo=(UserDemo) ac.getBean("user");
System.out.println(userDemo.getId()+userDemo.getName());
}
}
