1.程序中有Junit環(huán)境
　　2.導入一個jar包.spring與junit整合jar包
　　spring-test-3.2.0.RELEASE.jar
　　3.測試代碼
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations="classpath:applicationContext.xml")
public class SpringTest {
@Autowired
private UserService userService;
@Test
public void demo1(){
userService.sayHello();
}
