  使用Spring Boot以来,遇到和解决过好几次不同的项目启动问题,大多数事故起于错误的配置和依赖。因此,本文用于汇总这些问题,以及提供相应的解决方案,帮助大家更快的定位和排除故障。

1. Unregistering JMX-exposed beans on shutdown

  项目中没有添加spring-boot-starter-web模块依赖,在启动 Application 运行过程中会出现这个错误。

  解决方案,引入spring-boot-starter-web模块

代码语言:javascript
复制
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

  网上大多数的解决方案是通过添加spring-boot-starter-tomcat依赖来解决,但实测证明此方法不可行。

2. Cannot determine embedded database driver class for database type NONE

  项目中添加了spring-boot-starter-data-jpa模块依赖,而且没有配置数据源连接信息的情况下,启动 Application 过程中会出现该错误,原因是Spring Boot在启动时会自动注入数据源和配置JPA。

  • 解决方案1,移除spring-boot-starter-data-jpa模块依赖;
  • 解决方案2,将启动类注解@SpringBootApplication修改如下;
代码语言:javascript
复制
@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class,DataSourceTransactionManagerAutoConfiguration.class, HibernateJpaAutoConfiguration.class})
  • 解决方案3,在配置文件中添加数据库连接信息。
