这是我的 spring boot application.properties 的要点

#SPRING MVC
spring.view.prefix: /WEB-INF/jsp/
spring.view.suffix: .jsp
security.basic.enabled=false
logging.level.org.springframework.security=DEBUG

正在读取的 Controller

@Controller
public class ClientDashboardController  {

    private Logger logger = LoggerFactory.getLogger(ClientDashboardController.class);

    @RequestMapping(value="/dashboard")
    public String displayDashboard() {

        Object principal =
                SecurityContextHolder.getContext().getAuthentication().getPrincipal();

        return "dashboard";
    }


    @RequestMapping(value="/login")
    public String index() {
        return "index";
    }
}

我的 pom.xml 的要点

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-actuator</artifactId>
    </dependency>

这是错误信息

我哪里配置错了？

我已经遇到过这个错误。我相信您正在扩展错误的类(class)。检查this链接

你需要将你的类扩展到这个SpringBootServletInitializer

@EnableAutoConfiguration
@EnableWebMvc
@ComponentScan({"org.app.genesis.client.controller","org.app.genesis.commons.service",
    "org.app.app.commons.security","org.app.genesis.inventory.service","org.app.genesis.client.auth"})
@EnableJpaRepositories(basePackages = "org.app.genesis.*.repo")
@EntityScan(basePackages = "org.app.genesis.*.model")
public class Application extends SpringBootServletInitializer{
  ...
}
