【问题描述】：
我目前正在开发一个 Vaadin spring 应用程序。根据应用规范，用户的认证/授权必须通过jdbcTemplate查询数据库来完成。如何解决这个问题？我正在使用 Spring Boot 1.4.2.RELEASE。
更新：此方法适用于 Spring Boot 1.1.x.RELEASE，但在最新版本中会产生以下错误消息。
Description:
The dependencies of some of the beans in the application context form a cycle:
┌─────┐
| jdbcAccountRepository defined in file [repositories\JdbcAccountRepository.class]
↑ ↓
| securityConfiguration.WebSecurityConfig (field services.JdbcUserDetailsServicessecurity.SecurityConfiguration$WebSecurityConfig.userDetailsService)
↑ ↓
| jdbcUserDetailsServices (field repositories.JdbcAccountRepository services.JdbcUserDetailsServices.repository)
└─────┘
原始代码如下所示：
AccountRepository：
public interface AccountRepository {
void createAccount(Account user) throws UsernameAlreadyInUseException;
Account findAccountByUsername(String username);
}
JdbcAccountRepository：
@Repository
public class JdbcAccountRepository implements AccountRepository {
private final Logger LOGGER = LoggerFactory.getLogger(this.getClass());
private final JdbcTemplate jdbcTemplate;
private final PasswordEncoder passwordEncoder;
@Autowired
public JdbcAccountRepository(JdbcTemplate jdbcTemplate, PasswordEncoder passwordEncoder) {
this.jdbcTemplate = jdbcTemplate;
this.passwordEncoder = passwordEncoder;
}
@Transactional
@Override
public void createAccount(Account user) throws UsernameAlreadyInUseException {
try {
jdbcTemplate.update(
"insert into Account (firstName, lastName, username, password, role) values (?, ?, ?, ?, ?)",
user.getFirstName(),
user.getLastName(),
user.getUsername(),
passwordEncoder.encode(
user.getPassword()),
user.getRole()
);
} catch (DuplicateKeyException e) {
throw new UsernameAlreadyInUseException(user.getUsername());
}
}
@Override
public Account findAccountByUsername(String username) {
return jdbcTemplate.queryForObject(
"select username, password, firstName, lastName, role from Account where username = ?",
(rs, rowNum) -> new Account(
rs.getString("username"),
rs.getString("password"),
rs.getString("firstName"),
rs.getString("lastName"),
rs.getString("role")),
username
);
}
}
JdbcUserDetailsServices：
@Service
public class JdbcUserDetailsServices implements UserDetailsService {
private final Logger LOGGER = LoggerFactory.getLogger(this.getClass());
@Autowired
JdbcAccountRepository repository;
@Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
try {
Account account = repository.findAccountByUsername(username);
User user = new User(
account.getUsername(),
account.getPassword(),
AuthorityUtils.createAuthorityList(
account.getRole()
)
);
return user;
} catch (DataAccessException e) {
LOGGER.debug("Account not found", e);
throw new UsernameNotFoundException("Username not found.");
}
}
}
安全配置：
@Configuration
@ComponentScan
public class SecurityConfiguration {
@Autowired
ApplicationContext context;
@Autowired
VaadinSecurity security;
@Bean
public PreAuthorizeSpringViewProviderAccessDelegate preAuthorizeSpringViewProviderAccessDelegate() {
return new PreAuthorizeSpringViewProviderAccessDelegate(security, context);
}
@EnableGlobalMethodSecurity(securedEnabled = true,prePostEnabled = true)
public static class GlobalMethodSecurity extends GlobalMethodSecurityConfiguration {
@Bean
@Override
protected AccessDecisionManager accessDecisionManager() {
return super.accessDecisionManager();
}
}
@Configuration
@EnableWebSecurity
public static class WebSecurityConfig extends WebSecurityConfigurerAdapter {
@Autowired
JdbcUserDetailsServices userDetailsService;
@Autowired
DataSource dataSource;
@Bean
public PasswordEncoder passwordEncoder() {
return NoOpPasswordEncoder.getInstance();
}
@Bean
public TextEncryptor textEncryptor() {
return Encryptors.noOpText();
}
/*
* (non-Javadoc)
* @see org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter
* #configure(org.springframework.security.config.annotation.web.builders.WebSecurity)
*/
@Override
public void configure(WebSecurity web) throws Exception {
//Ignoring static resources
web.ignoring().antMatchers("/VAADIN/**");
}
@Override
protected void configure(AuthenticationManagerBuilder auth)
throws Exception {
auth.userDetailsService(userDetailsService);
}
@Bean(name="authenticationManager")
@Override
public AuthenticationManager authenticationManagerBean() throws Exception {
return super.authenticationManagerBean();
}
/*
* (non-Javadoc)
* @see org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter
* #configure(org.springframework.security.config.annotation.web.builders.HttpSecurity)
*/
@Override
protected void configure(HttpSecurity http) throws Exception {
http
.exceptionHandling()
.authenticationEntryPoint(new LoginUrlAuthenticationEntryPoint("/"))
.and()
.authorizeRequests()
.antMatchers("/**").permitAll()
.and()
.csrf().disable();
}
}
}
P.S 如果将 Spring Boot 版本降级为 [1.1.5,1.2.0) ，则不会出现此问题（由于其他依赖，我必须使用最新的）

你的配置中没有使用（DataSource dataSource），为什么要注入？？
