Spring 安全性:其他bean可以访问全局AuthenticationManagerBuilder吗?
Spring Security: Can other beans access the global AuthenticationManagerBuilder?
我已经设置了样板 spring 安全配置器:
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {
@Autowired
private DataSource datasource;
@Override
protected void configure(HttpSecurity http) throws Exception {
// ...setting up security for routes, etc.
}
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
// here I have access to the AuthenticationManagerBuilder
// I can associate it with my datasource, set the password encoder, etc.
JdbcUserDetailsManager userDetailsService = new JdbcUserDetailsManager();
userDetailsService.setDataSource(datasource);
PasswordEncoder encoder = new BCryptPasswordEncoder();
auth.userDetailsService(userDetailsService).passwordEncoder(encoder);
auth.jdbcAuthentication().dataSource(datasource);
}
但我想要的是能够像这样从另一个 bean 访问 AuthenticationManagerBuilder:
@Service
public class MyUserService {
@Autowired
AuthenticationManagerBuilder builder;
public void createUser(...) {
//use builder here...
JdbcUserDetailsManager userDetailsService = new JdbcUserDetailsManager();
userDetailsService.setDataSource(datasource);
PasswordEncoder encoder = new BCryptPasswordEncoder();
builder.userDetailsService(userDetailsService)
.passwordEncoder(encoder);
builder.jdbcAuthentication().dataSource(datasource);
userDetailsService.createUser(new User(...));
}
是否有任何方法可以从其他 bean 访问自动传递给 configure()
方法的相同 AuthenticationManagerBuilder
实例?
AuthenticationManagerBuilder 实际上仅用于构建您的身份验证对象(即 UserDetails、AuthenticationProvider、AuthenticationManager)。它不适用于应用程序本身。
相反,我建议使用 UserDetailsManager API。您可以创建一个 UserDetailsManager Bean,将 UserDetailsManager 提供给 AuthenticationManagerBuilder 以创建 AuthenticationProvider 和 AuthenticationManager,然后您可以直接在代码中使用 UserDetailsManager。
像这样:
@EnableWebMvcSecurity
@Configuration
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {
...
@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth, UserDetailsService uds) throws Exception {
auth
.userDetailsService(uds)
.passwordEncoder(new BCryptPasswordEncoder());
}
@Bean
public UserDetailsManager udm(DataSource dataSource) {
JdbcUserDetailsManager udm = new JdbcUserDetailsManager();
udm.setDataSource(dataSource);
return udm;
}
}
@Service
public class MyUserService {
@Autowired
UserDetailsManager udm;
public void createUser(...) {
//use builder here...
udm.createUser(new User(...));
}
}
需要注意的一件事是我们利用了 AuthenticationManagerBuilder 的全局实例。为了确保在构建 AuthenticationProvider 和 AuthenticationManager 之前调用 configureGlobal 方法,您需要在配置上添加 EnableGlobalAuthentication、EnableWebMvcSecurity 或 EnableWebSecurity 注释 class(我们的示例已经这样做了)。
