Question

我正在创建一个基本的Spring MVC + Repositories + Security配置。我利用了THIS GUIDE并得到了我在下面报告的配置。根据该配置，我希望在localhost:8080/HPLAN/welcome显示一些欢迎页面;键入localhost:8080/HPLAN/后，我也会被重定向到该网址，但我总是收到404错误。服务器日志不会收到任何请求（服务器日志不显示任何“无请求映射”）。在部署位置，存在“HPLAN”文件夹。我还需要提一下，没有创建数据库表。

所以，我的配置是：

安全

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@SuppressWarnings("unused")
@Autowired
private DataSource dataSource;

@Autowired
private CustomUserDetailsService customUserDetailsService;

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

@Override
public void configure(WebSecurity web) throws Exception {
    web.ignoring().antMatchers("/resources/**"); // #3
}

@Override
protected void configure(HttpSecurity http) throws Exception {
    http.csrf().disable().authorizeRequests().antMatchers("/login", "/login/form**", "/register", "/logout")
            .permitAll() // #4
            .antMatchers("/admin", "/admin/**").hasRole("ADMIN") // #6
            .anyRequest().authenticated() // 7
            .and().formLogin() // #8
            .loginPage("/login/form") // #9
            .loginProcessingUrl("/login").failureUrl("/login/form?error").permitAll(); // #5
}

}

持久性

@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(basePackages = "com.tek4b.hplan.repositories")
public class PersistenceConfig {

@Autowired
private Environment env;

@Value("${init-db:false}")
private String initDatabase;

@Bean
public PlatformTransactionManager transactionManager() {
    EntityManagerFactory factory = entityManagerFactory().getObject();
    return new JpaTransactionManager(factory);
}

@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
    LocalContainerEntityManagerFactoryBean factory = new LocalContainerEntityManagerFactoryBean();

    HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
    vendorAdapter.setGenerateDdl(Boolean.TRUE);
    vendorAdapter.setShowSql(Boolean.TRUE);

    factory.setDataSource(dataSource());
    factory.setJpaVendorAdapter(vendorAdapter);
    factory.setPackagesToScan("com.tek4b.hplan.entities");

    Properties jpaProperties = new Properties();
    jpaProperties.put("hibernate.hbm2ddl.auto", env.getProperty("hibernate.hbm2ddl.auto"));
    factory.setJpaProperties(jpaProperties);

    factory.afterPropertiesSet();
    factory.setLoadTimeWeaver(new InstrumentationLoadTimeWeaver());
    return factory;
}

@Bean
public HibernateExceptionTranslator hibernateExceptionTranslator() {
    return new HibernateExceptionTranslator();
}

@Bean
public DataSource dataSource() {
    BasicDataSource dataSource = new BasicDataSource();
    dataSource.setDriverClassName(env.getProperty("jdbc.driverClassName"));
    dataSource.setUrl(env.getProperty("jdbc.url"));
    dataSource.setUsername(env.getProperty("jdbc.username"));
    dataSource.setPassword(env.getProperty("jdbc.password"));
    return dataSource;
}

@Bean
public DataSourceInitializer dataSourceInitializer(DataSource dataSource) {
    DataSourceInitializer dataSourceInitializer = new DataSourceInitializer();
    dataSourceInitializer.setDataSource(dataSource);
    ResourceDatabasePopulator databasePopulator = new ResourceDatabasePopulator();
    databasePopulator.addScript(new ClassPathResource("db.sql"));
    dataSourceInitializer.setDatabasePopulator(databasePopulator);
    dataSourceInitializer.setEnabled(Boolean.parseBoolean(initDatabase));
    return dataSourceInitializer;
}

}

的AppConfig

@Configuration
@ComponentScan(basePackages = {
    "com.tek4b.hplan" }, excludeFilters = @ComponentScan.Filter(type = FilterType.REGEX, pattern = {
            "com.tek4b.hplan.web.*" }) )
@PropertySource(value = { "classpath:application.properties" })
@EnableScheduling
@EnableAspectJAutoProxy
@EnableCaching
public class AppConfig {

@Autowired
private Environment env;

@Bean
public static PropertySourcesPlaceholderConfigurer placeHolderConfigurer() {
    return new PropertySourcesPlaceholderConfigurer();
}

@Bean
public CacheManager cacheManager() {
    return new ConcurrentMapCacheManager();
}

}

MVC：

@Configuration
@ComponentScan(basePackages = { "com.tek4b.hplan.web" })
@EnableWebMvc
public class WebMvcConfig extends WebMvcConfigurerAdapter {

@Override
public void addViewControllers(ViewControllerRegistry registry) {
    super.addViewControllers(registry);
    registry.addViewController("login/form").setViewName("login");
    registry.addViewController("welcome").setViewName("welcome");
    registry.addViewController("admin").setViewName("admin");
}

@Bean
public ViewResolver resolver() {
    InternalResourceViewResolver url = new InternalResourceViewResolver();
    url.setPrefix("/WEB-INF/jsp/");
    url.setSuffix(".jsp");
    return url;
}

@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
    registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");
}

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

@Bean(name = "messageSource")
public MessageSource configureMessageSource() {
    ReloadableResourceBundleMessageSource messageSource = new ReloadableResourceBundleMessageSource();
    messageSource.setBasename("classpath:messages");
    messageSource.setCacheSeconds(5);
    messageSource.setDefaultEncoding("UTF-8");
    return messageSource;
}

@Bean
public SimpleMappingExceptionResolver simpleMappingExceptionResolver() {
    SimpleMappingExceptionResolver b = new SimpleMappingExceptionResolver();
    Properties mappings = new Properties();
    mappings.put("org.springframework.dao.DataAccessException", "error");
    b.setExceptionMappings(mappings);
    return b;
}

}

Web.xml中

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee"

version="3.0">
<display-name>HPLAN</display-name>

我的项目结构：

我创建了数据库，服务器似乎正确启动：

无论我的要求如何，它都是这样的。怎么了？

============ UPDATE 6. AppInitializer类：

public class SpringWebAppInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {

    @Override
    protected Class<?>[] getRootConfigClasses() {
        return new Class<?>[] { AppConfig.class };
    }

    @Override
    protected Class<?>[] getServletConfigClasses() {
        return new Class<?>[] { WebMvcConfig.class };
    }

    @Override
    protected String[] getServletMappings() {

        return new String[] { "/" };
    }

    @Override
    protected Filter[] getServletFilters() {
        return new Filter[] { new DelegatingFilterProxy("springSecurityFilterChain"),
                new OpenEntityManagerInViewFilter() };
    }

}

Answer 1

在您的函数getServletMappings()中，更改

return new String[] { "/" };

到

return new String[] { "/*" };

Answer 2

您的项目没有＆＃34; Dynanic Web Project＆＃34;小面。

右键单击项目，然后选择＆＃34;属性＆＃34;。然后点击＆＃34; Project Facet＆＃34;。选择＆＃34;动态Web项目＆＃34;然后继续下一步。

<强>更新如果可以，那么检查＆＃34;部署组件＆＃34;在项目属性选项卡中。源文件夹应该具有＆＃34; WEB-INF / classes＆＃34;的目标，以及与部署相关的其他内容。

如果那也没关系，那么你需要转到＆＃34;服务器＆＃34;查看，并从那里删除服务器。重启Eclipse。然后添加一个新的服务器。
