我正在使用基于Java配置的Spring Security在我的项目中执行配置。
只有我在初始化Spring Security时遇到问题，我正在使用SecurityConfig.class类来初始化相应的设置，但问题是这个类有一个需要参数的构造函数。
我基于文档：
public class SecurityConfig implements ConfigAttribute {
....
//~ Constructors ==================
public SecurityConfig(String config) {
Assert.hasText(config, "You must provide a configuration attribute");
this.attrib = config;
}
....
}
SecurityApplicationContext.java
@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled=true)
@ComponentScan(basePackages="com.tiarebalbi.kupo.configuration.security")
public class SecurityApplicationContext extends WebSecurityConfigurerAdapter {
@Autowired
private DataSource dataSource;
@Autowired
private Environment env;
@Autowired
private KupoUserDetailsService userDetailService;
/**
* @param auth {@link AuthenticationManagerBuilder}
* @throws Exception {@link Exception}
*/
@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
auth.jdbcAuthentication()
.dataSource(dataSource)
.withDefaultSchema()
.and()
.userDetailsService(userDetailService)
.passwordEncoder(new KupoPasswordEncoder());
}
@Override
@Autowired
public AuthenticationManager authenticationManagerBean() throws Exception {
return super.authenticationManagerBean();
}
@Override
protected void configure(HttpSecurity http) throws Exception {
http
.authorizeRequests()
.antMatchers("/public/**", "/recover-password", "/recover/**").permitAll()
.anyRequest().authenticated()
.and()
.formLogin()
.loginPage("/login")
.loginProcessingUrl("/auth-verify")
.defaultSuccessUrl("/dashboard")
.failureUrl("/login?error")
.permitAll()
.and()
.logout()
.logoutRequestMatcher(new AntPathRequestMatcher("/logout")).logoutSuccessUrl("/login")
.and()
.rememberMe()
.and()
.sessionManagement()
.maximumSessions(this.env.getRequiredProperty("security.session.max", Integer.class))
.expiredUrl("/login?expired");
}
}
Dispatcher Servlet Initializer：
public class DispatcherServletInitializerContext extends AbstractAnnotationConfigDispatcherServletInitializer {
@Override
protected Class<?>[] getRootConfigClasses() {
return new Class<?>[] { SecurityConfig.class ,GlobalApplicationContext.class };
}
@Override
protected Class<?>[] getServletConfigClasses() {
return new Class<?>[] { WebApplicationContext.class, WebSocketApplicationContext.class };
}
@Override
protected String[] getServletMappings() {
return new String[] { "/" };
}
@Override
protected void customizeRegistration(Dynamic registration) {
registration.setInitParameter("dispatchOptionsRequest", "true");
registration.setAsyncSupported(true);
}
@Override
public void onStartup(ServletContext servletContext) throws ServletException {
super.onStartup(servletContext);
}
}

我通过将类设置为SecurityConfig.class @Bean并调整设置AuthenticationManager来解决问题
/**
* @return {@link SecurityConfig}
*/
@Bean
public SecurityConfig securityConfigBean() {
SecurityConfig config = new SecurityConfig("kupo-security");
return config;
}
/**
*
* @param auth {@link AuthenticationManagerBuilder}
* @throws Exception {@link Exception}
*/
@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
auth.authenticationProvider(authProviders().getDaoProvider());
}
@Bean
@Override
public AuthenticationManager authenticationManagerBean() throws Exception {
return new ProviderManager(authProviders());
}

您尝试在应用程序上下文中注册SecurityConfig.class。但正如异常消息所说：
java.lang.NoSuchMethodException: org.springframework.security.access.SecurityConfig.<init>()
当您向应用程序上下文添加任何类时，Spring会尝试使用默认构造函数对它们进行实例化。这意味着SecurityConfig中没有默认构造函数。
我也不知道你为什么试图在没有用@Configuration注释标记的应用程序上下文中注册类，并且里面没有任何@Bean注释。如果你参考：
您将在该教程中看到他们创建了名为SecurityConfig的类。 所以我认为你应该创建自己的SecurityConfig并完全导入这个而不是org.springframework.security.access.SecurityConfig
