Spring安全性，jdbcAuthentication

我刚刚开始使用spring安全性，并且在尝试为用户使用数据库时遇到了问题。Spring安全性，jdbcAuthentication

这是我实现WebApplicationInitializer：

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()，configureGlobal方法，我评论的方法线罚款。但是，当我尝试使用数据库时，我收到错误。

我做了autowired字段conn，从中我可以得到配置了Hikari连接池的dataSource对象。

我得到这个错误：

哪种错误？ – Marged

您是否已将@Bean注释添加到'glavni.db.DBConnection'？ – chomnoue

尝试直接自动连接数据源。像@Autowired \t DataSource dataSource;如果你使用的是Spring引导，否则创建它的bean – Afridi

我缺的是弹簧JDBC扶养的唯一的事情。

配置数据源在AppConfiguration类这样

@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：DriverClassName和URL值是为MySQL。你可以根据你使用的数据库来改变它。

最后，自动装配数据源在SecurityConfiguration类这样

@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=?"); 

    } 
}

他已经提到DBConnection与他的其他控制器工作正常。似乎他在加载bean的方式上存在问题。 – Ashish

是的。我只想让他尝试另一种方法，看看它是否适合他。按照你的建议，他会在github上上传他的项目。 – Perry
