自定义AuthenticationProvider无法@Autowire的解决
在AuthenticationProvider中使用@Autowired注入时始终报Null问题
找了半天发现应该在SecurityConfig配置类中
@EnableWebSecuritypublic class SecurityConfig extends WebSecurityConfigurerAdapter{
在设置AuthenticationProvider时
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()); }
之前的错误的设置方式是
@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
自定义AuthenticationProvider的简单例子xml 配置
<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>
net.mantis.security.auth.MyAuthenticationProvider
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; }}
net.mantis.security.auth.NMUserDetailsService
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; }}
以上为个人经验，希望能给大家一个参考，也希望大家多多支持。
