Question

这是我正在研究的练习项目，学习Spring Security和OAuth2。

链接到项目的zip - https://drive.google.com/open?id=0BxsYBg5XwboXdkpUdkhXWUd1Vmc

只要我添加以下课程，我的自动服务就会失败:( 它给出了NullPointerException。

@Configuration
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class MethodSecurityConfig extends GlobalMethodSecurityConfiguration {
    @Override
    protected MethodSecurityExpressionHandler createExpressionHandler() {
        return new OAuth2MethodSecurityExpressionHandler();
    }
}

我在下面的休息控制器中得到NullPointerException userService。

@RestController
@RequestMapping("/api/user")
public class UserCtrl {

@Autowired
@Qualifier("userService")
UserService userService;

@PreAuthorize("#oauth2.hasScope('write')")
@RequestMapping(method=RequestMethod.POST,consumes="application/json")
private @ResponseBody ResponseMessage registerUser(@RequestBody User user){
    user.setUser_id(-1);
    return userService.createUser(user);
}

@PreAuthorize("#oauth2.hasScope('none')")
@RequestMapping(method=RequestMethod.GET)
private @ResponseBody ResponseMessage loginUser(){

    CustomUserDetails temp =  (CustomUserDetails) SecurityContextHolder.getContext().getAuthentication().getPrincipal();
    System.out.println(temp.getUsername() + " logged in");

    ResponseMessage message = userService.getUserByUsername(temp.getUsername());

    if(message.getCode() == ResponseMessage.CODE_NOT_FOUND){
        return message;
    }else{
        temp.setUser((User)message.getData());
    }

    return userService.loginUser(temp.getUser().getUsername(),temp.getUser().getPassword());
}

@PreAuthorize("hasRole('ROLE_USER')")
@RequestMapping(method=RequestMethod.PUT,consumes="application/json")
private @ResponseBody ResponseMessage updateUser(@RequestBody User user){
    return userService.updateUser(user);
}

@PreAuthorize("hasRole('ROLE_USER')")
@RequestMapping(method=RequestMethod.DELETE,consumes="application/json")
private @ResponseBody ResponseMessage deleteUser(@RequestBody User user){
    return userService.deleteUser(user.getUser_id());
}
}

以下是我定义服务的方式：

@Service("userService")
public class UserServiceImpl implements UserService {

@Autowired
private UserDAO userDAO;

@Autowired
private RoleService roleService;

public UserServiceImpl() {
    System.out.println("service");
}

@Override
@Transactional
public ResponseMessage createUser(User user) {
    if (null == userDAO.getUserByUsername(user.getUsername())) {
        int id = userDAO.createUser(user);
        user.setUser_id(id);
        roleService.createRole(new Role(RoleType.ROLE_USER, user));

        return new ResponseMessage(ResponseMessage.CODE_CREATED, ResponseMessage.DESC_CREATED, user);
    } else {
        return new ResponseMessage(ResponseMessage.CODE_EXISTS, ResponseMessage.DESC_EXISTS, user);
    }
}

Mvc配置：

@EnableWebMvc
@Configuration
@ComponentScan({"com.rawal.sweetnote.*"})
public class WebMvcConfig extends WebMvcConfigurerAdapter{

@Override
public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
    configurer.enable();
}
}

Spring安全配置：

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter{

@Autowired
@Qualifier("userService")
UserService userDetailsService;

@Override
@Bean
public AuthenticationManager authenticationManagerBean() throws Exception {
    return super.authenticationManagerBean();
}

@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
    auth.userDetailsService(userDetailsService);
}   
}

安全初始化程序：

@Order(1)
public class SpringSecurityInitializer extends  AbstractSecurityWebApplicationInitializer{

}

DispatcherServletInitializer

public class AppInit extends AbstractAnnotationConfigDispatcherServletInitializer{

@Override
protected Class<?>[] getRootConfigClasses() {
    // TODO Auto-generated method stub
    return new Class[]{MethodSecurityConfig.class,WebMvcConfig.class};
}

@Override
protected Class<?>[] getServletConfigClasses() {
    // TODO Auto-generated method stub
    return null;
}

@Override
protected String[] getServletMappings() {
    // TODO Auto-generated method stub
    return new String[]{"/"};
}
}

Hibernate配置：

@Configuration
@EnableTransactionManagement
@PropertySource(value = { "classpath:app.properties" })
public class HibernateConfig {
/**
 * This field is automatically injected by the spring framework from app.properties
 */
@Autowired
private Environment environment;



/**
 * Creates a session factory
 * @return {@link SessionFactory}
 */
@Bean
public LocalSessionFactoryBean sessionFactory() {
    LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
    sessionFactory.setDataSource(dataSource());
    sessionFactory.setPackagesToScan(new String[] { "com.rawal.sweetnote.entities" });
    sessionFactory.setHibernateProperties(hibernateProperties());
    return sessionFactory;
}


/**
 * Creates a datasource after setting various database properties
 * @return {@link DataSource}
 */
@Bean
public DataSource dataSource() {
    DriverManagerDataSource dataSource = new DriverManagerDataSource();
    dataSource.setDriverClassName(environment.getRequiredProperty("db.drivername"));
    dataSource.setUrl(environment.getRequiredProperty("db.url"));
    dataSource.setUsername(environment.getRequiredProperty("db.username"));
    dataSource.setPassword(environment.getRequiredProperty("db.password"));
    return dataSource;
}


/**
 * Sets up the hibernate properties and returns an instance of it
 * @return {@link Properties}
 */
private Properties hibernateProperties() {
    Properties properties = new Properties();
    properties.put("hibernate.dialect", environment.getRequiredProperty("hibernate.dialect"));
    properties.put("hibernate.show_sql", environment.getRequiredProperty("hibernate.show_sql"));
    return properties;
}



/**
 * Creates a transaction manager using the sessionfactory injected by spring and returns an instance of it
 * @param {@link SessionFactory}
 * @return {@link HibernateTransactionManager}
 */
@Bean
@Autowired
public HibernateTransactionManager transactionManager(SessionFactory s) {
    HibernateTransactionManager txManager = new HibernateTransactionManager();
    txManager.setSessionFactory(s);
    return txManager;
}


/**
 * Creates a hibernate template instance from the injected session factory.
 * We use this to perform various db transactions.
 * @param {@link SessionFactory}
 * @return
 */
@Bean
@Autowired
public HibernateTemplate hibernateTemplate(SessionFactory sessionFactory) {
    HibernateTemplate hibernateTemplate = new HibernateTemplate();
    hibernateTemplate.setSessionFactory(sessionFactory);
    return hibernateTemplate;
}
}

OAuth2资源配置

@Configuration
@EnableResourceServer
public class OAuthResourceConfig extends ResourceServerConfigurerAdapter{

private static final String RESOURCE_ID = "restservice";

@Override
public void configure(HttpSecurity http) throws Exception {
    http.authorizeRequests().antMatchers("/api/**").authenticated()
    .antMatchers("/register").permitAll()
    .and().formLogin().permitAll()
    .and().logout().permitAll()
    .and().csrf().disable();
}

@Override
public void configure(ResourceServerSecurityConfigurer resources) throws Exception {
    resources.resourceId(RESOURCE_ID).stateless(false);
}
}

OAuth2服务器配置

@Configuration
@EnableAuthorizationServer
@PropertySource("classpath:app.properties")
public class OAuthServerConfig extends AuthorizationServerConfigurerAdapter{

@Autowired
private Environment env;


@Autowired
private UserService userDetailsService;

@Autowired
private AuthenticationManager authenticationManager;

@Override
public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
    endpoints.tokenStore(tokenStore()).tokenEnhancer(tokenEnhancer()).authenticationManager(authenticationManager).userDetailsService(userDetailsService);
}

@Override
public void configure(AuthorizationServerSecurityConfigurer security) throws Exception {
    security.allowFormAuthenticationForClients();
}

@Override
public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
    clients.inMemory().withClient("client")
    .authorizedGrantTypes("password","refresh_token","implicit")
    .scopes("read","write","trust")
    .refreshTokenValiditySeconds(Integer.parseInt(env.getProperty("refresh_token_validity")))
    .accessTokenValiditySeconds(Integer.parseInt(env.getProperty("access_token_validity")));
}

@Bean

    InMemoryTokenStore store = new InMemoryTokenStore();
    store.setAuthenticationKeyGenerator(new UniqueAuthenticationKeyGenerator());
    return store;
}

@Bean

更新1

修改了如下的用户控制器（添加了greet1（）和greet2（））。现在有趣的是，UserService属性对于这些新方法不是空的。但是对于其他方法它仍然是空的。

@PreAuthorize("hasRole('ROLE_ADMIN')")
@RequestMapping("/greet")
public String greet() {
    System.out.println(service.sayHello());
    return "Hello";
}

@PreAuthorize("hasRole('ROLE_USER')")
@RequestMapping("/greet2")
public String greet2() {
    System.out.println(service.sayHello());
    return "Hello";
}


@PreAuthorize("hasRole('ROLE_ADMIN')")
@RequestMapping(method=RequestMethod.POST,consumes="application/json")
private @ResponseBody ResponseMessage registerUser(@RequestBody User user){
    user.setUser_id(-1);
    return service.createUser(user);
}

@PreAuthorize("hasRole('ROLE_USER')")
@RequestMapping(path="/",method=RequestMethod.GET)
private @ResponseBody ResponseMessage loginUser(){

    CustomUserDetails temp =  (CustomUserDetails) SecurityContextHolder.getContext().getAuthentication().getPrincipal();
    System.out.println(temp.getUsername() + " logged in");


    service.sayHello();
    ResponseMessage message = service.getUserByUsername(temp.getUsername());

    if(message.getCode() == ResponseMessage.CODE_NOT_FOUND){
        return message;
    }else{
        temp.setUser((User)message.getData());
    }

    return service.loginUser(temp.getUser().getUsername(),temp.getUser().getPassword());
}

但是，如果我禁用prePostEnabled，一切正常。这感觉真的很蠢！帮助!!!!!

Answer 1

好的，这真是愚蠢的＆＃34;我＆＃34;。我只是注意到我的控制器中的所有方法都是私有的。 :( 公开解决问题。

无论其!!!!!当@EnableGlobalMethodSecurity(prePostEnabled = true)设置为false时，我仍然感觉很好。

如果你明白了，请评论。

希望这可以帮助像我一样愚蠢的人。：/

Answer 2

确保您的控制器为public而不是private 例如

@PreAuthorize("hasRole('ROLE_ADMIN')")
@RequestMapping(method=RequestMethod.POST,consumes="application/json")
public ResponseMessage registerUser(@RequestBody User user){
   // your code here
}
