标签： spring maven jdbc spring-boot vaadin

我真的需要帮助.. 我尝试使用依赖项创建simple webapps springboot：web，postgresql，jdbc，vaadin。 当开始运行我的应用程序时，应用程序将无法启动并且会抛出异常。 异常告诉＆＃34; ..没有JdbcTemplate类型的限定bean＆＃34;。 stackoverflow中的一些建议是添加工件spring-boot-starter-jdbc，但是我的pom已经做了并且仍然无法工作。

在我的配置下面

的src /主/资源/ application.properties：

spring.datasource.url=jdbc:postgresql://localhost:5432/sehati
spring.datasource.username=sehati
spring.datasource.password=password

@SpringBootApplication
public class SiaApplication {

    public static void main(String[] args) {
        SpringApplication.run(SiaApplication.class, args);
    }
}

VadinUI：

@SpringUI
@Theme("valo")
public class SehatiDashboardUI extends UI {
    @Override
    protected void init(VaadinRequest request) {
        setContent(new Label("Hello World"));
    }
}

Spring组件：

@Component
public class LookupService {

    @Autowired
    private JdbcTemplate jdbcTemplate;

    public List<Lookup> findAll() {
        return jdbcTemplate.query("select id, type, label, name from lookup", 
                (rs, rowNum) -> new Lookup(rs.getLong("id"), rs.getString("type"), rs.getString("label"), rs.getString("label")));
    }

我也尝试使用H2数据库。我的应用程序可以启动，但似乎数据源连接始终使用spring-boot-jdbc（url='jdbc:h2:mem:testdb;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=false', username='sa'）中的预配置数据源，即使我已经在application.properties中描述了新的数据源。

有人能找到我的项目有什么问题吗？ 真的很感谢你的帮助。

1 个答案:

答案 0 :(得分：0)

我尝试新的IDE（eclipse，sts），创建新工作区，导入项目，创建新项目但仍面临一些问题。

最后，我的应用程序在删除我的.m2文件夹后可以正常运行。但我仍然不知道我的mvn存储库中发生了什么。

谢谢
