我使用 Spring 初始化程序 创建了一个 Spring boot 项目，目前只有启动代码。

示例代码

@SpringBootApplication
public class EcommerceApplication {

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


@Controller
@RequestMapping(value = "/")
public class HomeController {

    @GetMapping
    public String index() {
        return "index";
    }
}

我希望它从 templates 文件夹返回 index.html 页面。相反，我被重定向到 http://localhost:8080/login 地址并要求输入用户名/密码。在 application.properties 文件中，我尝试使用配置，

server.port=8080
spring.application.name=Bootstrap Spring Boot
spring.thymeleaf.cache=false
spring.thymeleaf.enabled=true 
spring.thymeleaf.prefix=classpath:/templates/
spring.thymeleaf.suffix=.html
spring.datasource.driver-class-name=org.h2.Driver
spring.datasource.url=jdbc:h2:mem:bootapp;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE
spring.datasource.username=testuser
spring.datasource.password=testpassword
server.error.path=/error
server.error.whitelabel.enabled=false 

我尝试使用用户名 testuser 和密码 testpassword 登录。这行不通。

我在项目中使用如下pom.xml，

这里有什么问题？

最佳答案

如果您不想登录页面(来自 Spring-Security)，请从 pom.xml 中删除以下依赖项并执行 maven更新以刷新类路径上的依赖关系。

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

或者如果你想使用 Spring-Security 那么在 console 它将显示默认密码，如下所示:

Using default security password: ce6c3d39-8f20-4a41-8e01-803166bb99b6

默认用户名将是 user

关于Spring Boot 项目显示登录页面，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/46265775/
