Question

我刚开始使用spring安全性，在尝试为用户使用数据库时遇到了问题。

这是我实施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上课

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

}

我有SecurityWebApplicationInitializer课程

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=?");

    }
}

这与我在inMemoryAuthentication()方法中使用configureGlobal方法的行很好用。但是当我尝试使用数据库时，我会收到错误。

我制作了自动连接的字段conn，从中可以获得使用Hikari连接池配置的dataSource对象。

我收到此错误：

Answer 1

在AppConfiguration类中配置数据源，如下所示

@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进行更改。

最后，像你这样

在SecurityConfiguration类中自动装配数据源

@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=?");

    }
}

Answer 2

我唯一缺少的是spring-jdbc dependancy。

Spring security，jdbcAuthentication
