Spring Boot 项目显示登录页面

Question

我用 --- 创建了一个 Spring boot 项目， Spring initializer 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，我尝试使用的配置，

 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。

我在项目中使用以下 pom.xml ，

 <?xml version="1.0" encoding="UTF-8"?>

这里有什么问题？

Answer 1

这是默认行为。要改变这一点，您有几个选择：

您可以删除 Spring Boot Security 依赖项：

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

您可以禁用自动配置。这样做；在您的主要课程中，到： @SpringBootApplication 附加： (exclude = { SecurityAutoConfiguration.class }) 使其看起来像：

    @SpringBootApplication(exclude = { SecurityAutoConfiguration.class })
   public static void main(String[] args) {
            SpringApplication.run(SpringBootSecurityApplication.class, args);
        }
    }

您也可以从 application.properties 文件中执行此操作

有关禁用自动配置和设置您自己的更多信息。参考： Spring Boot 安全自动配置

Answer 2

如果您不想要登录页面（来自 Spring-Security ）从您的 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项。

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

或者如果你想使用 Spring-Security 然后在 console 它将显示如下默认密码：

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

默认用户名是 user
