使用 MongoDB 将 SpringBoot webapp 部署到 tomcat 时出错

Question

我是 SpringBoot 的新手。我已经使用带有嵌入式 tomcat 的 springboot 成功执行了一个 webapp。尝试将此 spring boot webapp 部署到外部 Tomcat 服务器时遇到问题。 我收到以下错误

无法确定数据库类型 NONE 的嵌入式数据库驱动程序类。如果您想要一个嵌入式数据库，请在类路径中放置一个受支持的数据库。如果您有要从特定配置文件加载的数据库设置，您可能需要激活它（当前没有配置文件处于活动状态）。

If you want an embedded database please put a supported one on the classpath. If you have database settings to be loaded from a particular profile you may need to active it (no profiles are currently active).

我正在使用带有 jdk7 的 spring boot 1.3.3。 任何帮助都会很好 - 因为有人在将 Spring Boot 应用程序作为 WAR 部署到外部服务器时遇到类似问题？

Answer 1

关键是spring-boot-starter-security 正在拉动spring-jdbc 依赖项。此依赖项触发DataSourceAutoConfiguration 创建DataSource，因为您尚未明确定义它假定在内存中，如H2、HSQLDB 或Derby。但是这些不在您的类路径中，因此启动失败。

现在您有 2 个选项来解决此问题。第一个是通过将exclude 作为exclude 添加到@SpringBootApplication 注释来显式禁用DataSourceAutoConfiguration。

@SpringBootApplication(exclude= DataSourceAutoConfiguration.class)
public class ApplicatationStart extends SpringBootServletInitializer { ... }

专业提示：您还应该删除@Configuration、@ComponentScan 和@EnableAutoConfiguration，因为@SpringBootApplication 暗示了这些。

另一个选项是从 spring-boot-starter-security 依赖项中排除 spring-jdbc 依赖项。

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-security</artifactId>
    <excludes>
        <exclude>
            <groupId>org.springframework</groupId>
            <artifactId>spring-jdbc</artifactId>
        </exclude>
    </excludes>
</dependency>
