java – 创建名为defaultServletHandlerMapping的bean时出错

前端之家收集整理的这篇文章主要介绍了java – 创建名为defaultServletHandlerMapping的bean时出错前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
我将所有的 XML Spring配置转换为 Java代码,但是我无法运行所有的测试(他们以前使用过的),因为我有一个丑陋的异常:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'defaultServletHandlerMapping' defined in class path resource [org/springframework/web/servlet/config/annotation/DelegatingWebMvcConfiguration.class]: Bean instantiation via factory method Failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.web.servlet.HandlerMapping]: Factory method 'defaultServletHandlerMapping' threw exception; nested exception is java.lang.IllegalArgumentException: A ServletContext is required to configure default servlet handling

这是我的考试类:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes=ApplicationContextTest.class)
public class AccountServiceTest {
  ..
}

和我的ApplicationContextTest:

@Configuration
@EnableTransactionManagement
@PropertySource({ "classpath:databaseTest.properties" })
@ComponentScan(basePackages = { "org.example.springproject" })
public class ApplicationContextTest {

    @Autowired
    private Environment env;

    @Bean(name = "dataSource")
    public DataSource dataSource() {
        return new EmbeddedDatabaseBuilder()
            .setType(EmbeddedDatabaseType.Hsql)
            .addScript("classpath:sql/schema.sql")
            .addScript("classpath:sql/test-data.sql")
            .build();
    }

    @Bean(name = "sessionFactory")
    public LocalSessionfactorybean sessionFactory() {
        LocalSessionfactorybean sessionFactory = new LocalSessionfactorybean();
        sessionFactory.setDataSource(dataSource());
        sessionFactory.setPackagesToScan(new String[] { "org.example.springproject.domains" });
        sessionFactory.setHibernateProperties(hibernateProperties());

        return sessionFactory;
    }

    @Bean(name = "transactionManager")
    public HibernateTransactionManager transactionManager() {
        HibernateTransactionManager txManager = new HibernateTransactionManager();
        txManager.setSessionFactory(sessionFactory().getObject());

        return txManager;
    }

    @SuppressWarnings("serial")
    private Properties hibernateProperties() {
        return new Properties() {
            {
                setProperty("hibernate.cache.provider_class",env.getProperty("hibernate.provider_class"));
                setProperty("hibernate.show_sql",env.getProperty("hibernate.show_sql"));
                setProperty("hibernate.hbm2ddl.auto",env.getProperty("hibernate.hbm2ddl"));
            }
        };
    }
}

我尝试在我的测试类上放置@WebAppConfiguration,但这没有工作.
该项目是一个Spring MVC项目,但现在我正在测试服务层,那么为什么我需要把这个注释放在我的课上呢?
即使有这个注释,另一个错误即将到来.
那么这里有什么呢?

解决方法

您的配置是正常的,除了一个地方

@ComponentScan(basePackages = { “org.example.springproject” })

我会假设你的包中有其他@Configuration,这是由@ComponentScan(在您的异常中出现的DelegatingWebMvcConfiguration,最有可能由@EnableWebMvc在外部@Configuration中的某个地方导入)所选择的.

可能的解决方案是在组件扫描中使用过滤器.

@ComponentScan(basePackages = { “org.example.springproject” },excludeFilters = { @Filter(type = FilterType.ANNOTATION,value = Configuration.class) })

猜你在找的Java相关文章
