WebSecurityConfigurerAdapter过时，新方法替代

1、AuthenticationManager对象注入IOC

@Configuration
public class SecurityConfig {
@Autowired
private AuthenticationConfiguration authenticationConfiguration;
@Bean
public AuthenticationManager authenticationManager() throws Exception{
AuthenticationManager authenticatiOnManager= authenticationConfiguration.getAuthenticationManager();
return authenticationManager;
}
}

使用方法照常注入使用即可

@Service
public class LoginServiceImpl implements LoginService {
@Autowired
private AuthenticationManager authenticationManager;
...
}

2、配置过滤链

@Configuration
public class SecurityConfig {
@Bean
SecurityFilterChain filterChain(HttpSecurity http)throws Exception{
return http.csrf().disable()
.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS)
.and()
.authorizeRequests()
.antMatchers("/user/login").anonymous()
.anyRequest().authenticated()
.and()
.addFilterBefore(jwtAuthenticationTokenFilter,UsernamePasswordAuthenticationFilter.class)
.build();
}
}
