Spring Java Config不加载资产

Question

我试图从Spring XML配置迁移到Java基础，我至少运行它，但资产（CSS，JS，IMG）不加载，我得到一个错误500从响应。 资产文件夹位于WEB-INF相同级别的webapp文件夹下 任何人都知道我该如何修复它？可能是配置上的错误。

和我的配置类

@Configuration 
@ComponentScan(basePackages = {"br.com.cheetah.catalog.*"}) 
@Import({SecurityContext.class, PersistenceContext.class}) 
@EnableWebMvc 
public class SpringMvcContext extends WebMvcConfigurerAdapter 
{ 

    @Override 
    public void addResourceHandlers(ResourceHandlerRegistry registry) 
    { 
     registry.addResourceHandler("/asset/**").addResourceLocations("../webapp/asset/**").setCachePeriod(20); 
    } 

    @Bean 
    public InternalResourceViewResolver viewResolver() 
    { 
     InternalResourceViewResolver viewResolver = new InternalResourceViewResolver(); 
     viewResolver.setViewClass(JstlView.class); 
     viewResolver.setPrefix("/WEB-INF/pages/"); 
     viewResolver.setSuffix(".jsp"); 
     return viewResolver; 
    } 
}

的持久性配置

@Configuration 
@EnableJpaRepositories(basePackages = {"br.com.cheetah.catalog.repository"}, 
         entityManagerFactoryRef = "entityManagerFactory", 
         transactionManagerRef = "transactionManager") 
@EnableTransactionManagement(proxyTargetClass = true) 
public class PersistenceContext 
{ 
    @Bean(name = "entityManagerFactory") 
    public LocalContainerEntityManagerFactoryBean entityManagerFactoryBean() 
    { 
     LocalContainerEntityManagerFactoryBean entityManagerFactoryBean = new LocalContainerEntityManagerFactoryBean(); 
     entityManagerFactoryBean.setPersistenceUnitName("PersistenceUnit"); 
     return entityManagerFactoryBean; 

    } 

    @Bean(name = "transactionManager") 
    public JpaTransactionManager transactionManager() 
    { 
     JpaTransactionManager transactionManager = new JpaTransactionManager(); 
     transactionManager.setEntityManagerFactory(entityManagerFactoryBean() 
                  .getObject()); 
     return transactionManager; 
    } 

    @Bean 
    public PersistenceAnnotationBeanPostProcessor 
    persistenceAnnotationBeanPostProcessor() 
    { 
     return new PersistenceAnnotationBeanPostProcessor(); 
    } 
} 

初始化程序

@Order(1) 
public class SpringInitializer extends 
           AbstractAnnotationConfigDispatcherServletInitializer 
{ 
    @Override 
    protected Class<?>[] getRootConfigClasses() 
    { 
     return new Class<?>[]{SpringMvcContext.class}; 
    } 

    @Override 
    protected Class<?>[] getServletConfigClasses() 
    { 
     return null; 
    } 

    @Override 
    protected String[] getServletMappings() 
    { 
     return new String[]{"/"}; 
    } 
} 

安全配置

感谢安德烈·斯特凡，我把它简单地更换工作，为

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