我有一个spring应用程序配置类,其中实例bean.

应用类：

@Configuration
@EnableAspectJAutoProxy
@EnableSpringDataWebSupport
@EnableTransactionManagement
@ComponentScan(basePackageClasses = Application.class)
@PropertySource(value = {"classpath:foo.properties"})
@EnableJpaRepositories(basePackageClasses = Application.class)
@EnableJpaAuditing
public class Application {

    @Inject
    private Environment env;

    @Bean
    JndiTemplate jndiTemplate() {
        return new JndiTemplate();
    }

    @Bean
    public DataSource dataSource() {        
        DataSource dataSource = getDataSource();
        if (dataSource == null) {
            dataSource = new BasicDataSource();
            ((BasicDataSource) dataSource).setUsername(env.getProperty("jdbc.user"));
            ((BasicDataSource) dataSource).setPassword(env.getProperty("jdbc.password""));

            ((BasicDataSource) dataSource).setDriverClassName(env.getProperty("jdbc.driverClassName"));
            ((BasicDataSource) dataSource).setUrl(env.getProperty("jdbc.url"));
        }
        return dataSource;
    }

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

    //....
}

MvcConfiguration类：

@Configuration
@ComponentScan(basePackageClasses = Application.class,includeFilters = @Filter({Controller.class,Component.class}),useDefaultFilters = true)
class MvcConfiguration extends WebMvcConfigurationSupport {
    private static final String MESSAGES = "classpath:/i18n";

    private static final String VIEW_PREFIX = "/WEB-INF/views/";

    @Inject
    private Environment env;

    @Override
    public RequestMappingHandlerMapping requestMappingHandlerMapping() {
        RequestMappingHandlerMapping requestMappingHandlerMapping = super.requestMappingHandlerMapping();
        requestMappingHandlerMapping.setUseSuffixPatternMatch(false);
        requestMappingHandlerMapping.setUseTrailingSlashMatch(true);

        return requestMappingHandlerMapping;
    }

    @Bean(name = "messageSource")
    public MessageSource messageSource() {
        ReloadableResourceBundleMessageSource messageSource = new ReloadableResourceBundleMessageSource();
        messageSource.setBasename(MESSAGES);
        messageSource.setCacheSeconds(5);

        return messageSource;
    }

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

    @Bean
    public MultipartResolver filterMultipartResolver(){
        CommonsMultipartResolver resolver = new CommonsMultipartResolver();
        resolver.setMaxUploadSize(Long.parseLong(env.getProperty("multipart.max.size")));
        return resolver;
    }

    //....

}

和SecurityConfiguration类：

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
class SecurityConfiguration extends WebSecurityConfigurerAdapter {

    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }


    //....

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        //logout por POST con el valor de token csrf
        http.authorizeRequests()
                .antMatchers("/static/**").permitAll()
                .anyRequest().authenticated()
                .and()
            .formLogin()
                .loginPage("/login")
                .permitAll()
                .failureUrl("/login?error=1")
                .loginProcessingUrl("/authenticate")
                .and()
            .logout()
                .logoutUrl("/logout")
                .logoutSuccessUrl("/signin")
                .permitAll();
    }

}

我如何用JUnit测试它们？如何测试bean是在spring上下文中创建的？
