java - 无法加载ApplicationContext(Spring Boot)

Question

我正在尝试按照 Spring 网站上的示例测试我的应用程序。

这些是我的依赖项:

dependencies {
    compile('org.springframework.boot:spring-boot-starter-data-jpa')
    compile("org.springframework.boot:spring-boot-starter-security")
    compile('org.springframework.boot:spring-boot-starter-web')
    compile("org.springframework.boot:spring-boot-starter-thymeleaf")
    compile("org.thymeleaf.extras:thymeleaf-extras-springsecurity4")
    runtime('org.springframework.boot:spring-boot-devtools')
    runtime('com.h2database:h2')
    runtime('mysql:mysql-connector-java')
    compileOnly('org.projectlombok:lombok')
    testCompile('org.springframework.boot:spring-boot-starter-test')
    testCompile('org.springframework.security:spring-security-test')
}

这是测试类:

@RunWith(SpringRunner.class)
@SpringBootTest
@AutoConfigureMockMvc
public class ProductControllerTest {

    @Autowired
    private MockMvc mockMvc;

    @Test
    public void testHomePage() throws Exception {
        this.mockMvc.perform(get("/")).andDo(print()).andExpect(status().isOk());
    }

}

我收到错误:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaConfiguration.class]: Invocation of init method failed; nested exception is java.lang.NoClassDefFoundError: javax/xml/bind/JAXBException

java.lang.IllegalStateException: Failed to load ApplicationContext

知道是什么原因造成的吗？我没有任何特定的配置文件，只有安全配置和 webconfig。

网络配置:

    public class WebConfig implements WebMvcConfigurer {

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/images/**", "/css/**", "/fragments/**")
                .addResourceLocations("classpath:/static/images/", "classpath:/static/css/", "classpath:/fragments/");
    }
}

输出中的以下行:

java.lang.NoClassDefFoundError: javax/xml/bind/JAXBException

告诉我们找不到类javax.xml.bind.JAXBException。

正如 @Antot 提到的，将以下依赖项添加到您的 graddle 应该可以解决该问题:

compile('javax.xml.bind:jaxb-api:2.3.0')

对于使用 Maven 的用户，请使用以下命令:

<dependency>
    <groupId>javax.xml.bind</groupId>
    <artifactId>jaxb-api</artifactId>
    <version>2.3.0</version>
</dependency>
