这篇文章主要介绍了如何解决SpringSecurity自定义AuthenticationProvider无法@Autowire的问题,具有一定借鉴价值,感兴趣的朋友可以参考下,希望大家阅读完这篇文章之后大有收获,下面让小编带着大家一起了解一下。
在AuthenticationProvider中使用@Autowired注入时始终报Null问题
@EnableWebSecurity public class SecurityConfig extends WebSecurityConfigurerAdapter{
应该使用@Bean的方式设置
@Bean CustomAuthenticationProvider customAuthenticationProvider() { return new CustomAuthenticationProvider(); } @Override protected void configure(AuthenticationManagerBuilder auth) throws Exception { auth.authenticationProvider(customAuthenticationProvider()); }
@Override protected void configure(AuthenticationManagerBuilder auth) throws Exception { auth.authenticationProvider(new CustomAuthenticationProvider()); }
好了,这就可以实现AuthenticationProvider时自由的使用@Autowired了
<authentication-manager> <authentication-provider ref="myAuthenticationProvider" /> </authentication-manager> <beans:bean id="userDetailsService" class="net.mantis.security.auth.NMUserDetailsService"/> <beans:bean id="myAuthenticationProvider" class="net.mantis.security.auth.MyAuthenticationProvider"> <beans:property name="userDetailsService"> <beans:bean class="net.mantis.security.auth.NMUserDetailsService"> </beans:bean> </beans:property> </beans:bean>
public class MyAuthenticationProvider implements AuthenticationProvider { UserDetailsService userDetailsService; public Authentication authenticate(Authentication authentication) throws AuthenticationException { //username System.out.println("user name: "+authentication.getName()); //password System.out.println("password: "+authentication.getCredentials()); System.out.println("getPrincipal: "+authentication.getPrincipal()); System.out.println("getAuthorities: "+authentication.getAuthorities()); System.out.println("getDetails: "+authentication.getDetails()); UserDetails userDetails = (UserDetails)this.userDetailsService.loadUserByUsername(authentication.getName()); UsernamePasswordAuthenticationToken result = new UsernamePasswordAuthenticationToken( userDetails, authentication.getCredentials(),userDetails.getAuthorities()); return result; } public boolean supports(Class authentication) { return true; } public void setUserDetailsService(UserDetailsService userDetailsService){ this.userDetailsService = userDetailsService; } }
public class NMUserDetailsService implements UserDetailsService { @Override public UserDetails loadUserByUsername(String userName) throws UsernameNotFoundException { ArrayList list = new ArrayList(); list.add(new SimpleGrantedAuthority("ROLE_SUPERVISOR")); User details = new User("rod", "koala", list); return details; } }
