在SecurityConfig中配置UserDetailsService
在使用UserDetailsService时，我们需要将其配置到SecurityConfig中。在配置中，我们可以指定使用哪个UserDetailsService实现类，并为其指定一个PasswordEncoder对象，用于对密码进行加密。示例如下：
代码语言：javascript复制@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Autowired
private UserDetailsService userDetailsService;
@Autowired
private JwtAuthenticationEntryPoint jwtAuthenticationEntryPoint;
@Autowired
private JwtRequestFilter jwtRequestFilter;
@Autowired
private PasswordEncoder passwordEncoder;
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.userDetailsService(userDetailsService).passwordEncoder(passwordEncoder);
}
@Override
protected void configure(HttpSecurity http) throws Exception {
http.csrf().disable()
.authorizeRequests().antMatchers("/authenticate").permitAll().
anyRequest().authenticated().and().
exceptionHandling().authenticationEntryPoint(jwtAuthenticationEntryPoint).and().sessionManagement()
.sessionCreationPolicy(SessionCreationPolicy.STATELESS);
http.addFilterBefore(jwtRequestFilter, UsernamePasswordAuthenticationFilter.class);
}
@Bean
public PasswordEncoder passwordEncoder() {
return new BCryptPasswordEncoder();
}
@Bean
public AuthenticationManager authenticationManagerBean() throws Exception {
return super.authenticationManagerBean();
}
}在上述代码中，我们通过auth对象的userDetailsService()方法将UserDetailsService实现类注入到AuthenticationManagerBuilder中。在这里，我们还通过passwordEncoder()方法为PasswordEncoder对象指定了一个BCryptPasswordEncoder实现类，用于对密码进行加密。
