java - 如何让 Spring 使用多个上下文 Autowiring 集成测试类？

Question

我的一个集成测试使用多个 Spring 上下文文件。似乎 Spring 仅从第一个上下文而不是第二个上下文中 Autowiring bean。有谁知道我做错了什么或如何解决这个问题？

@RunWith(SpringJUnit4ClassRunner.class)@ContextConfiguration(locations = {        "classpath:/META-INF/spring/applicationContext.xml",        "classpath:/META-INF/spring/applicationContext-security.xml"})@Configurablepublic class UserDetailsServiceImplIntegrationTest {    @Autowired    UserDataOnDemand dod;    // @Autowired does not work for this bean from applicationContext-security.xml    UserDetailsService userDetailsService;    @Before    public void setup() {        dod.init();        // workaround for autowiring problem        userDetailsService = (UserDetailsService)ctx.getBean("userDetailsService");    }    @Test    public void testLoadUser() {        UserDetails ud = userDetailsService.loadUserByUsername("david@somewhere.co.za");        Assert.assertEquals("david@somewhere.co.za", ud.getUsername());    }}

我正在使用 Spring 3.0.3。

这是当我取消注释 UserDetailsS​​ervice 的 @Autowired 行时的堆栈跟踪:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'za.co.acme.app.security.UserDetailsServiceImplIntegrationTest': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: org.springframework.security.core.userdetails.UserDetailsService za.co.acme.app.security.UserDetailsServiceImplIntegrationTest.userDetailsService; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [org.springframework.security.core.userdetails.UserDetailsService] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

该 bean 肯定存在，因为“按名称”查找有效，并且它的类型正确。

一种解决方法是创建一个新的单个配置文件(我们称之为“test-configuration.xml”)，其中包括 applicationContext.xml 和 applicationContext-security.xml。然后您可以在测试中使用这些配置。

测试配置.xml:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">

    <import resource="classpath:/META-INF/spring/applicationContext.xml"/>
    <import resource="classpath:/META-INF/spring/applicationContext-security.xml"/>
</beans>

UserDetailsS​​erviceImplIntegrationTest.java:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("/test-configuration.xml")
@Configurable
public class UserDetailsServiceImplIntegrationTest {
...
}
