在@Configuration类之后SpringbootTest失败:创建名为“datasource”的bean时出错
在@Configuration类之后SpringbootTest失败:创建名为“datasource”的bean时出错
提问于 2021-07-27 22:14:35
我正在尝试执行几个测试用例，这些测试用例之前工作得很好。我最近添加了一个配置类，如下所示：
@Configuration
public class DBConfig {
@Value("${spring.datasource.username:}")
private String username;
@Value("${spring.datasource.url:}")
private String url;
@Bean
@DependsOn("passwordProvider")
public DataSource datasource(PasswordProvider passwordProvider) {
return DataSourceBuilder
.create()
.url(url)
.username(username)
.password(new String(passwordProvider.getKeyByName("DB_PASSWORD").getKey()))
.build();
}
} 现在，我的所有SpringbootTests都失败了，出现以下异常：
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.cloud.autoconfigure.RefreshAutoConfiguration$JpaInvokerConfiguration': Invocation of init method failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.boot.autoconfigure.jdbc.DataSourceInitializerInvoker': Invocation of init method failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'datasource' defined in class path resource [com/example/configuration/DBConfig.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [javax.sql.DataSource]: Factory method 'datasource' threw exception; nested exception is java.lang.NullPointerException

只需在spring启动测试中提及，它就会加载您的配置类：
@RunWith(SpringRunner.class)
@SpringBootTest(classes = {DBConfig.class})
public class SpringBootIntegrationTest {
// ...
