我正在学习 Spring boot，虽然我可以运行我的项目，但当我尝试访问它时，希望看到一个空白页面，我收到登录/密码提示，尽管我在应用程序中定义了一些值.properties 文件，我总是收到错误。
pom.xml 是:

application.properties 是:
spring.datasource.url = jdbc:mysql://localhost:3306/app
spring.datasource.name=app
spring.datasource.username=app
spring.datasource.password=appPassword
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.jpa.database=mysql
spring.jpa.database-platform=org.hibernate.dialect.MySQLDialect
security.user.name=master
security.user.password=abc123
最后，我的主要类(class)是:
@Configuration
@EnableAutoConfiguration
@ComponentScan
@Controller
public class AppNameApplication {
@ResponseBody
@RequestMapping(value = "/")
public String entry() {
return "AppName";
}
public static void main(String[] args) {
SpringApplication.run(AppNameApplication.class, args);
}
}
虽然我是一名经验丰富的 Spring 用户，但我正在学习 Spring boot 以提高我的开发技能。
我在浏览器上收到的错误是:
Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback. Tue Aug 09 13:33:59 BRT 2016 There was an unexpected error (type=Unauthorized, status=401). Bad credentials
我知道现在没有发生什么事情，但这是否是预期的行为？我至少应该能够登录吗？
最佳答案
我会将此答案作为更详细的“评论”发布，因为我无法提供详细的评论。
在您的 pom.xml 中，您已添加 Spring Security 启动器:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-security</artifactId>
</dependency>
这意味着 Spring 将启用安全性来访问您的端点，因此会出现未经授权错误。 Spring Security 的默认行为是锁定整个应用程序。
因此，您必须相应地配置 spring security 才能启用您的访问权限。
详见此链接https://spring.io/guides/gs/securing-web/
您必须创建一个 WebSecurity 配置器，如下示例:
@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
http
.authorizeRequests()
.antMatchers("/", "/home").permitAll()
.anyRequest().authenticated()
.and()
.formLogin()
.loginPage("/login")
.permitAll()
.and()
.logout()
.permitAll();
}
@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
auth
.inMemoryAuthentication()
.withUser("user").password("password").roles("USER");
}
}
在使用 Spring Security 之前，您可以首先删除安全启动器并尝试访问您的端点。一旦您确认您的 API 按预期工作，您就可以开始使用安全性了。同样，我建议你从头开始，没有入门者，在学习的同时将它们一一添加，而不是一次性添加所有内容。
