构建后，如何将用户添加到inMemoryAuthentication构建器中? [英] How can I add users to the inMemoryAuthentication builder after it has been built?

问题描述

在应用程序的初始加载期间，我设法将所有用户加载到AuthenticationManagerBuilder中，但是我需要在启动后添加用户.

I have managed to load all the users into the AuthenticationManagerBuilder during the initial load of the application, but I have a requirement to add users post-startup.

启动:

public class WebSecurityConfig extends WebSecurityConfigurerAdapter

...

auth.inMemoryAuthentication().withUser(email).password(password).roles(roles.toArray(new String[roles.size()])).and().passwordEncoder(encoder());

这在一段时间内效果很好，但是我有一个用例，可以在应用程序运行时添加用户.

This works great for a point in time, but I have a use case where users can be added while the application is running.

我可以通过哪种方法在启动后(通过控制器/服务)进行?我在想它可能是InMemoryUserDetailsManager(它包含createUser()方法)，但是我不确定如何引用或配置它.

By which method can I do this post-startup (via controller/service)? I'm thinking it might be the InMemoryUserDetailsManager (it contains the createUser() method) but I'm not sure how to reference or configure it.

推荐答案

以下代码将满足您的要求:

The following code will do what you are asking:

@Configuration
@EnableWebMvcSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        //whatever here
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(inMemoryUserDetailsManager());
    }

    @Bean
    public InMemoryUserDetailsManager inMemoryUserDetailsManager() {
        final Properties users = new Properties();
        users.put("user","pass,ROLE_USER,enabled"); //add whatever other user you need
        return new InMemoryUserDetailsManager(users);
    }

}

使用您在超级简单的控制器上方配置的InMemoryUserDetailsManager，该控制器仅添加并检查用户的存在，如下所示:

Using the InMemoryUserDetailsManager you configured above a super simple controller that just adds and checks for the existence of a user would look like:

@RestController
@RequestMapping("user")
public class SimpleSecurityController {

    private final InMemoryUserDetailsManager inMemoryUserDetailsManager;

    @Autowired
    public SimpleSecurityController(InMemoryUserDetailsManager inMemoryUserDetailsManager) {
       this.inMemoryUserDetailsManager = inMemoryUserDetailsManager;
    }

    @RequestMapping("exists/{username}")
    public boolean userExists(@PathVariable("username") String username ) {
        return inMemoryUserDetailsManager.userExists(username);
    }

    @RequestMapping("add/{username}/{password}")
    public String add(@PathVariable("username") String username, @PathVariable("password") String password) {
        inMemoryUserDetailsManager.createUser(new User(username, password, new ArrayList<GrantedAuthority>()));
        return "added";
    }
}

还请注意，如果您使用的是Spring Boot的自动配置，则需要添加

Also note that if you are using Spring Boot's autoconfiguration you will need to add

@EnableAutoConfiguration(exclude = SecurityAutoConfiguration.class)

防止Spring Boot尝试自动配置安全性

to prevent Spring Boot from trying to autoconfigure security

更新 正如@AdamMichalik所指出的，已弃用@EnableWebMvcSecurity，应将其替换为@EnableWebSecurity

Update As noted by @AdamMichalik, @EnableWebMvcSecurity is deprecated and should be replaced by @EnableWebSecurity
