添加基于弹簧IOC JUnit的3.0.0的Java 4.7测试

有一个文档http://static.springsource.org/spring/docs/2.5.6/reference/testing.html如何使用XML配置添加到JUnit测试IoC的支持，但我不能找到例如基于Java的配置...添加基于弹簧IOC JUnit的3.0.0的Java 4.7测试

例如，我曾经为基础的java bean：

public class AppConfig 
{ 
    @Bean 
    public Test getTest() { return new Test(); } 
}

和测试：

@RunWith(SpringJUnit4ClassRunner.class) 
public class IocTest 
{ 
    @Autowired 
    private Test test; 

    @Test 
    public void testIoc() 
    { 
     Assert.assertNotNull(test); 
    } 
}

我应该补充，使基于Java的豆到我的JUnit测试，而无需使用XML的CONFIGS？

通常我使用：

new AnnotationConfigApplicationContext(AppConfig.class);

，但如果你得到一个空值可能它不加载应用程序上下文它并不适用于测试工作...

更新： Spring 3.1将支持开箱即用，请参阅Spring 3.1 M2: Testing with @Configuration Classes and Profiles。

看来这个功能还没有被Spring支持。但是，它可以轻松实现：

public class AnnotationConfigContextLoader implements ContextLoader { 

    public ApplicationContext loadContext(String... locations) throws Exception { 
     Class<?>[] configClasses = new Class<?>[locations.length]; 
     for (int i = 0; i < locations.length; i++) { 
      configClasses[i] = Class.forName(locations[i]); 
     }   
     return new AnnotationConfigApplicationContext(configClasses); 
    } 

    public String[] processLocations(Class<?> c, String... locations) { 
     return locations; 
    } 
}

@RunWith(SpringJUnit4ClassRunner.class) 
@ContextConfiguration(loader = AnnotationConfigContextLoader.class, 
    value = "com.sample.AppConfig") 
public class IocTest { 
    @Autowired 
    TestSerivce service; 

    @Test 
    public void testIoc() 
    { 
     Assert.assertNotNull(service.getPredicate()); 
    } 
}

@Configuration 
public class ApplicationConfig 
{ 
    ... 

    @Bean 
    public NotExistsPredicate getNotExistsPredicate() 
    { 
     return new NotExistsPredicate(); 
    } 

    @Bean 
    public TestService getTestService() { 
     return new TestService(); 
    } 
}

谢谢，但仍然无法得到这个工作...我的测试类：http://pastebin.com/m4125a931，ApplicationConfig：http ：//pastebin.com/m2842d2a1，TestService：http://pastebin.com/m1ac16e48。然后，我单击NetBeans“测试文件”并获取断言失败（assertNotNull）和此日志：http://pastebin.com/mad10742。你能建议一些事情吗？ – 2010-02-09 16:16:17

@Vladimir：你不能简单地用new创建自动装配对象。它应该从上下文中获得。我添加了一个如何使用注解配置上下文的@ Bean注释方法创建'TestService'的示例。 – axtavt 2010-02-09 16:45:49

谢谢，axtavt。 – 2010-02-09 17:13:06

。

注意，默认情况下它与料其载入“类路径：/com/test/IocTest-context.xml”（假设IocTest.java包是com.test）

如果它不存在尝试加入

@RunWith(SpringJUnit4ClassRunner.class) 
@ContextConfiguration(locations = { "PATH_TO_YOUR_APP_CONTEXT/yourApplicationContext.xml" }) 
public class IocTest 
{ 
    @Autowired 
    private Test test; 

    @Test 
    public void testIoc() 
    { 
     Assert.notNull("test is null", test); 
    } 
}

我想配置ApplicationContext而不使用任何xml配置，使用基于java的配置。有一个问题的例子（AppConfig类）。 – 2010-02-09 12:29:07

Genereally，为什么这不起作用指定它（断言失败）：

public class IocTest 
{ 
    @BeforeClass 
    public static void initSpringIoc() 
    { 
     AnnotationConfigApplicationContext ctx = new AnnotationConfigApplicationContext(ApplicationConfig.class); 
     NotExistsPredicate predicate = ctx.getBean(NotExistsPredicate.class); 
     LoggerFactory.getLogger(IocTest.class).debug(predicate.toString()); 
    } 

    @Test 
    public void testIoc() 
    { 
     TestService service = new TestService(); 
     Assert.assertNotNull(service.getPredicate()); // assert fails 
    } 
} 

public class TestService 
{ 
    @Autowired 
    private NotExistsPredicate predicate; 

    public NotExistsPredicate getPredicate() 
    { 
     return predicate; 
    } 
}

日志输出：

这不起作用，因为你实例化它。但这不应该是一个答案 - 它应该是一个编辑你的问题 – Bozho 2010-02-09 14:48:43

这是对我工作......

从http://www.swiftmind.com/de/2011/06/22/spring-3-1-m2-testing-with-configuration-classes-and-profiles/

采取

package com.example; 

@RunWith(SpringJUnit4ClassRunner.class) 
// ApplicationContext will be loaded from the 
// OrderServiceConfig class 
@ContextConfiguration(classes=OrderServiceConfig.class, 
    loader=AnnotationConfigContextLoader.class) 
public class OrderServiceTest { 

    @Autowired 
    private OrderService orderService; 

    @Test 
    public void testOrderService() { 
     // test the orderService 
    } 
}
