我有一个实体“AppUser”的存储库,如下所示:
@Repository
public interface AppUserRepository extends CrudRepository<AppUser, Long>{
public AppUser findByUserName(String username);
public void delete(AppUser user);
}
它被自动连接到我的 UserService 类中:
@Service("userService")
public class UserService {
@Autowired
AppUserRepository repository;
public AppUser registerNewAppUser(AppUser user) {
AppUser u = repository.findByUserName(user.getUsername());
if (u!=null)
return null;
return repository.save(user);
}
UserService 自动连接到我的 CustomUserDetailsService 中,如下所示:
@Service("userDetailsService")
public class CustomUserDetailsService implements UserDetailsService {
@Autowired
private UserService userService;
最后自动连接到 WebSecurityConfiguration 为:
@Configuration
@EnableWebSecurity
public class WebSecurityConfiguration extends WebSecurityConfigurerAdapter {
@Autowired
private DataSource datasource;
@Autowired
private CustomUserDetailsService customUserDetailsService;
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.jdbcAuthentication().dataSource(datasource)
.and()
.userDetailsService(customUserDetailsService);
// @formatter:on
}
更新:我遵循了这里的一些建议,并更新了错误和 WebSecurityConfiguration 文件,如上所示。
我现在得到的错误是:
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.security.config.annotation.web.configuration.WebSecurityConfiguration': Injection of autowired dependencies failed;
nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire method: public void org.springframework.security.config.annotation.web.configuration.WebSecurityConfiguration.setFilterChainProxySecurityConfigurer(org.springframework.security.config.annotation.ObjectPostProcessor,java.util.List) throws java.lang.Exception;
nested exception is org.springframework.beans.factory.BeanExpressionException: Expression parsing failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'webSecurityConfiguration': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException:
Could not autowire field: private javax.sql.DataSource showcase.WebSecurityConfiguration.datasource; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException:
No qualifying bean of type [javax.sql.DataSource] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}
所以,我认为我需要以某种方式做两件事:
为它提供一个 DataSource 类型的合格 bean(我认为 repo 应该符合条件,但不知何故不是)
做
setFilterChainProxySecurityConfigurer
. 不知道该怎么做。我按照教程创建了:public class WebMVCApplicationInitializer implements WebApplicationInitializer { public void onStartup(ServletContext container) { ServletRegistration.Dynamic registration = container.addServlet("dispatcher", new DispatcherServlet()); registration.setLoadOnStartup(1); registration.addMapping("*.request"); } }
要添加 SpringSecurityFilterChain,我假设我需要在这里调用 addFilter 但它需要一个过滤器类。我需要创建它吗?另外,这个初始化程序是由调度程序 servlet 自动拾取的,还是我需要以某种方式配置它?
