从Java调用RestAPI时,找不到UsernamePasswordAuthenticationToken的AuthenticationProvider可能是由于以下原因导致的:
解决此问题的步骤如下:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-security</artifactId>
</dependency>
@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Autowired
private CustomAuthenticationProvider authenticationProvider;
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.authenticationProvider(authenticationProvider);
}
@Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests()
.antMatchers("/api/**").authenticated()
.and()
.httpBasic();
}
}
@Component
public class CustomAuthenticationProvider implements AuthenticationProvider {
@Override
public Authentication authenticate(Authentication authentication) throws AuthenticationException {
String username = authentication.getName();
String password = authentication.getCredentials().toString();
// 在此处进行自定义的身份验证逻辑
return new UsernamePasswordAuthenticationToken(username, password, new ArrayList<>());
}
@Override
public boolean supports(Class<?> authentication) {
return authentication.equals(UsernamePasswordAuthenticationToken.class);
}
}
