由于不满意的依赖关系，SpringBoot应用程序上下文未启动

问题描述 投票：0回答：1

我已经在如下配置类中配置了一个bean

@Configuration
public class WebServiceConfiguration {

    @Bean
    public Jaxb2Marshaller jaxb2Marshaller() {
        Jaxb2Marshaller jaxb2Marshaller = new Jaxb2Marshaller();
        jaxb2Marshaller.setPackagesToScan("package");
        return jaxb2Marshaller;
    }

}

下面是依赖于我已配置的bean的类：

@Component
public class BClient {

    @Autowired
    private Jaxb2Marshaller jaxb2Marshaller;

    private WebServiceTemplate template;

    public JAXBElement<GetBankResponseType> getDetails(String blz) {
        ...
        return response;
    }

}

当我尝试启动Spring Boot时，它失败并显示以下错误：

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'bankUpClient': Unsatisfied dependency expressed through field 'jaxb2Marshaller'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'jaxb2Marshaller' defined in class path resource [soapws/configuration/SoapConfiguration.class]: Invocation of init method failed; nested exception is org.springframework.oxm.UncategorizedMappingException: Unknown JAXB exception; nested exception is javax.xml.bind.JAXBException: Implementation of JAXB-API has not been found on module path or classpath.

更奇怪的是，集成测试成功运行。即使如此，集成测试也会启动应用程序上下文。

@ExtendWith(SpringExtension.class)
@SpringBootTest
public class BClientTest {

    @Autowired
    private BClient client;


    @BeforeEach
    public void setup() {
    }

    @Test
    void testGetDetails() {
       ...
    }

}

我需要一些帮助，以了解为什么会这样。提出任何想法...

谢谢

我认为您的JAXB没有运行时依赖项，只需将适当的依赖项添加到Maven或gradle的依赖项部分。

这应该适用于gradle：

compile('javax.xml.bind:jaxb-api:2.3.0')
compile('javax.activation:activation:1.1')
compile('org.glassfish.jaxb:jaxb-runtime:2.3.0')

这是针对Maven的：

<!-- https://mvnrepository.com/artifact/javax.xml.bind/jaxb-api -->
<dependency>
    <groupId>javax.xml.bind</groupId>
    <artifactId>jaxb-api</artifactId>
    <version>2.3.0-b170201.1204</version>
</dependency>

<!-- https://mvnrepository.com/artifact/javax.activation/activation -->
<dependency>
    <groupId>javax.activation</groupId>
    <artifactId>activation</artifactId>
    <version>1.1</version>
</dependency>

<!-- https://mvnrepository.com/artifact/org.glassfish.jaxb/jaxb-runtime -->
<dependency>
    <groupId>org.glassfish.jaxb</groupId>
    <artifactId>jaxb-runtime</artifactId>
    <version>2.3.0-b170127.1453</version>
</dependency>
