Spring Boot项目显示Login页面

Question

我创建了一个Spring boot项目,目前Spring initializer只有初始代码.

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index.html从templates文件夹返回页面.相反,我被重定向到该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和密码登录testpassword.这没有用.

我pom.xml在项目中使用以下内容,

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

这是什么问题？

Answer 1

如果您不想登录页面(从Spring-Security)删除您的以下依赖项pom.xml

<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

默认用户名是 user

Answer 2

这是默认行为。要改变这一点，你有几个选择：

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；在您的主类中，@SpringBootApplication添加到：append:(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 3

当您包含spring-boot-starter-security 时，将自动显示登录页面。

要删除此登录页面-

1. 如果您使用Maven，则删除此依赖项并重建项目。已经有一些答案了。只需删除块（pom.xml）：

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

2. 如果有人使用Gradle，只需从依赖项块（build.gradle）中删除以下块并重新加载 build.gradle：

dependencies {
    //implementation 'org.springframework.boot:spring-boot-starter-security'
    ...
}

3. 如果您不想更改 pom.xml 或 build.gradle 之类的配置文件，那么源代码级别的更改将最适合您。为此，需要更新主类，使用@SpringBootApplication(exclude = {SecurityAutoConfiguration.class})更改@SpringBootApplication注释。这不包括参数将删除安全配置。

@SpringBootApplication(exclude = {SecurityAutoConfiguration.class})
public class SpringCacheApplication {

    public static void main(String[] args) {
    ...
    }
    ...
}

4. 此外，如果您想保留登录页面，那么您可以使用生成的安全密码登录。您可以在控制台中找到它，如下所示： 使用生成的安全密码： d408ce6f-470d-4**4-950a-81**9651f321

{
"usename" : "user",
"password": "d408ce6f-470d-4**4-950a-81**9651f32"
}

有关更多信息，您可以阅读Spring Security。

Answer 4

您可以在项目中添加一个类，用于网络安全配置，如下所示：

@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
                .authorizeRequests().antMatchers("/*").permitAll()
                .and()
                .csrf().disable();

    }
}
