java - BeanCreationException NoSuchBeanDefinitionException 使用 Spring roo

Question

当我尝试访问我的服务时抛出异常，我使用 spring roo 创建了我的 spring 数据 jpa 存储库，该存储库生成了文件 applicationContext-jpa.xml

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

  <repositories base-package="org.bixin.dugsi" />

</beans:beans>

我的 applicationContext.xml 位于同一目录 META-INF/spring/ 中，我确保包含组件扫描

<context:component-scan base-package="org.bixin.dugsi">
    <context:exclude-filter expression=".*_Roo_.*" type="regex"/>
    <context:exclude-filter expression="org.springframework.stereotype.Controller" type="annotation"/>
</context:component-scan>

我如何使用它的测试用例如下:

@RooIntegrationTest(entity = UserAccount.class)
@ContextConfiguration(locations = { "classpath:META-INF/spring/applicationContext.xml" })
public class UserAccountIntegrationTest extends AbstractJUnit4SpringContextTests {


    @PersistenceUnit(unitName = "persistenceUnit")
    private EntityManagerFactory factory;
    PasswordService testsPasswordService = new CustomPasswordService();

    @Autowired
    private AccountSettingsRepository accountSettingsRepository;

    @Autowired
    private AccountService accountService;

    @Test
    public void testAccount(){

        accountService.saveAccountSettings(accountSettings);
        Assert.assertNotNull(accountSettings);
    }

我不知道是什么导致了这个异常，我告诉它在哪里可以找到服务实现和存储库。完整的堆栈跟踪如下:

帐户设置存储库

打包 org.bixin.dugsi.repositories;

import java.util.List;

import org.bixin.dugsi.domain.AccountSettings;
import org.springframework.roo.addon.layers.repository.jpa.RooJpaRepository;

@RooJpaRepository(domainType = AccountSettings.class)
public interface AccountSettingsRepository {

}

检查您的 applicationContext-jpa.xml 是否由您的主上下文加载。

为此，请检查您的 applicationContext.xml 是否包含:

<import resource="applicationContext-jpa.xml"/>
