Spring的junit的集成测试

• 程序中有Junit环境.
• 导入一个jar包.spring与junit整合jar包.

• * spring-test-3.2.0.RELEASE.jar

• 测试代码:（这种方式自动注入，测试方便）

  package cn.test;
  
  import org.junit.Test;
  import org.junit.runner.RunWith;
  import org.springframework.beans.factory.annotation.Autowired;
  import org.springframework.test.context.ContextConfiguration;
  import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
  
  import cn.myservice.UserService;
  /**
   * spring集成Junit的测试
   * @author Administrator
   *
   */
  @RunWith(SpringJUnit4ClassRunner.class)
  @ContextConfiguration(locations="classpath:applicationContext.xml")
  public class SpringTest {
  	@Autowired
  	private UserService userService;
  	@Test
  	public void demo1(){
  		userService.sayHello();
  	}
  }
  

  原来初学时的测试：比较麻烦，代码量大。

  package cn.spring.annotation2;
  
  import org.junit.Test;
  import org.springframework.context.ApplicationContext;
  import org.springframework.context.support.ClassPathXmlApplicationContext;
  
  public class SpringTest2 {
  	@Test
  	public void demo1(){
  		ApplicationContext applicationContext=new ClassPathXmlApplicationContext("applicationContext.xml");
  		Car car=(Car) applicationContext.getBean("car");
  		Product product=(Product) applicationContext.getBean("product");
  		System.out.println(car);
  		System.out.println(product);
  	}
  }
