Spring安全性，jdbcAuthentication

我剛剛開始使用spring安全性，並且在嘗試爲用戶使用數據庫時遇到了問題。Spring安全性，jdbcAuthentication

這是我實現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類

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

}

我SecurityWebApplicationInitializer類

public class SecurityWebApplicationInitializer 
    extends AbstractSecurityWebApplicationInitializer { 
}

和SecurityConfiguration類

@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=?"); 

    } 
}

這與inMemoryAuthentication()，configureGlobal方法，我評論的方法線罰款。但是，當我嘗試使用數據庫時，我收到錯誤。

我做了autowired字段conn，從中我可以得到配置了Hikari連接池的dataSource對象。

我得到這個錯誤：

哪種錯誤？ – Marged

您是否已將@Bean註釋添加到'glavni.db.DBConnection'？ – chomnoue

嘗試直接自動連接數據源。像@Autowired \t DataSource dataSource;如果你使用的是Spring引導，否則創建它的bean – Afridi

我缺的是彈簧JDBC扶養的唯一的事情。

配置數據源在AppConfiguration類這樣

@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值是爲MySQL。你可以根據你使用的數據庫來改變它。

最後，自動裝配數據源在SecurityConfiguration類這樣

@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=?"); 

    } 
}

他已經提到DBConnection與他的其他控制器工作正常。似乎他在加載bean的方式上存在問題。 – Ashish

是的。我只想讓他嘗試另一種方法，看看它是否適合他。按照你的建議，他會在github上上傳他的項目。 – Perry
