Spring Boot jdbc数据源自动配置在独立的tomcat上失败

在尝试在独立的tomcat（7）实例上部署和启动Spring启动应用程序时，我们遇到了一个问题，即找不到自动配置的spring数据源bean并抛出相应的exception：

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [javax.sql.DataSource] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)} at org.springframework.beans.factory.support.DefaultListableBeanFactory.raiseNoSuchBeanDefinitionException(DefaultListableBeanFactory.java:1060) at org.springframework.beans.factory.support.DefaultListableBeanFactory.doResolveDependency(DefaultListableBeanFactory.java:920) at org.springframework.beans.factory.support.DefaultListableBeanFactory.resolveDependency(DefaultListableBeanFactory.java:815) at org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor$AutowiredFieldElement.inject(AutowiredAnnotationBeanPostProcessor.java:480) ... 84 more 

简单的jdbc spring.datasource在application.properties中正确配置，应用程序本身与嵌入式tomcat实例完美匹配，作为独立的spring引导应用程序。

看起来好像无法正确读取和/或处理application.properties文件，或者在数据源自动配置完成之前触发了一些其他bean（例如REST控制器中的服务）的注入。

不使用嵌入式tomcat时是否需要任何额外配置？ 或者有没有人遇到过类似的问题？

简单的应用和配置：

 @EnableAutoConfiguration @Configuration @ComponentScan("com.foo") public class Application extends SpringBootServletInitializer { public static void main(String[] args) { SpringApplication.run(Application.class, args); } @Override protected SpringApplicationBuilder configure(SpringApplicationBuilder application) { return application.sources(Application.class); } } 

application.properties：

 spring.datasource.url=jdbc:mysql://localhost:3306/mydatabase spring.datasource.username=username spring.datasource.password=password spring.datasource.driverClassName=com.mysql.jdbc.Driver 

数据源使用示例：

 @Repository public class MyRepositoryImpl implements MyRepository { @Autowired private DataSource dataSource; ... } 

Pom父和依赖：

  org.springframework.boot spring-boot-starter-parent 0.5.0.M6    mysql mysql-connector-java 5.1.27   org.springframework.boot spring-boot-starter-web   org.springframework.boot spring-boot-starter-jdbc   org.springframework spring-orm 4.0.0.RC1

Answer 1

这很可能是0.5.0.M6版本和您正在使用的Tomcat版本的问题。 它适用于Spring Boot 0.5.0.M7和Tomcat 7.0.47。

Answer 2

嗨，请确保您没有错过JPA库。

弹簧引导起动数据JPA

Answer 3

我之前遇到了同样的问题，并通过添加解决了同样的问题

 @PropertySource("classpath:application.properties") 

在Application.java中希望这会有所帮助

Answer 4

 @EnableAutoConfiguration(exclude = { DataSourceAutoConfiguration.class, HibernateJpaAutoConfiguration.class, DataSourceTransactionManagerAutoConfiguration.class }) 

为我的1.3.3版本工作

Answer 5

对我来说，它是在JdbcTemplateAutoConfiguration中抛出exception。 我在Application.java中添加了排除JdbcTemplateAutoConfiguration。 希望能帮助到你。

 @SpringBootApplication(exclude = { DataSourceAutoConfiguration.class, HibernateJpaAutoConfiguration.class, JdbcTemplateAutoConfiguration.class })
