java - Spring 安全，jdbcAuthentication

标签 java mysql spring spring-mvc spring-security

我刚开始使用 spring security，在尝试为用户使用数据库时遇到了问题。

这是我实现 WebApplicationInitializer 的地方:

public class AppInit implements WebApplicationInitializer{

    public void onStartup(ServletContext servletContext) throws ServletException {
        // TODO Auto-generated method stub

        AnnotationConfigWebApplicationContext context = new AnnotationConfigWebApplicationContext();
        context.register(AppConfiguration.class);

        ServletRegistration.Dynamic registration = 
                servletContext.addServlet("dispatcher", new DispatcherServlet(context));
        registration.setLoadOnStartup(1);
        registration.addMapping("/services/rest/*");

    }

}

AppConfiguration 类

@Configuration
@EnableWebMvc
@ComponentScan(basePackages = "glavni")
public class AppConfiguration {

}

我有 SecurityWebApplicationInitializer 类

public class SecurityWebApplicationInitializer 
   extends AbstractSecurityWebApplicationInitializer {
}

和SecurityConfiguration类

@Configuration
@EnableWebSecurity
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {

    @Autowired
    DBConnection conn;

    @Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
        // auth.inMemoryAuthentication().withUser("user").password("password").roles("USER");
        auth.jdbcAuthentication().dataSource(conn.initializeDataSource())
                .usersByUsernameQuery("select username, password from user where username=?")
                .authoritiesByUsernameQuery("select user_id, authority from authorization where user_id=?");

    }
}

这与 inMemoryAuthentication() 配合使用时效果很好，这是我在 configureGlobal 方法中评论的行。但是当我尝试使用数据库时出现错误。

我制作了 Autowiring 的字段 conn，从中我可以获得配置了 Hikari 连接池的 dataSource 对象。

我收到这个错误:

最佳答案

像这样在您的 AppConfiguration 类中配置数据源

@Configuration
@EnableTransactionManager
@ComponentScan(basePackages = "glavni")
public class AppConfiguration {

   @Bean
   public DataSource dataSource(){
      DriverManagerDataSource dataSource = new DriverManagerDataSource();
      dataSource.setDriverClassName("com.mysql.cj.jdbc.Driver");
      dataSource.setUrl("jdbc:mysql://localhost:3306/your-database-name");
      dataSource.setUsername( "database-username" );
      dataSource.setPassword( "database-username" );
      return dataSource;
   }

}

注意:DriverClassName 和 Url 值适用于 MySQL。您可以根据您使用的数据库更改此设置。

最后，像这样在您的 SecurityConfiguration 类中 Autowiring 数据源

@Configuration
@EnableWebSecurity
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {

    @Autowired
private DataSource dataSource;

    @Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
        // auth.inMemoryAuthentication().withUser("user").password("password").roles("USER");
        auth.jdbcAuthentication().dataSource(dataSource)
                .usersByUsernameQuery("select username, password from user where username=?")
                .authoritiesByUsernameQuery("select user_id, authority from authorization where user_id=?");

    }
}
