Spring不扫描和注册托管bean@AutoWired不注入任何内容，并且#{SpringManagedBean}在EL中不可用

Spring不会在Spring引导应用程序中扫描和注册托管bean。 我不知道如何配置

springboot+JSF+MyBatic

应用程序

Application.java

@Configuration
@ComponentScan(basePackages={""})
@EnableAutoConfiguration
public class Application extends SpringBootServletInitializer {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

    @Bean
    public ServletRegistrationBean servletRegistrationBean() {
        FacesServlet servlet = new FacesServlet();
        ServletRegistrationBean servletRegistrationBean = new ServletRegistrationBean(servlet, "*.jsf");
        return servletRegistrationBean;
    }

}

MyDataSourceConfig.java

@Configuration
@MapperScan("com.jg.myapp.mapper")
public class MyDataSourceConfig {

    @Autowired
    private DataSource dataSource; <----- it is also problem. cannot inject DataSource.

    @Bean
    public SqlSessionFactory sqlSessionFactory() throws Exception {
        SqlSessionFactoryBean sessionFactory = new SqlSessionFactoryBean();
        sessionFactory.setDataSource(dataSource);
        sessionFactory.setConfigLocation(new ClassPathResource("/mybatis-config.xml"));
        return sessionFactory.getObject();
    }
}

对于初学者，停止混合框架版本（boot 1.2.5和1.1.4）。另外，spring boot已经为您管理了这些版本。当您使用SpringBoot时，您的web.xml没有做任何事情。您是在运行嵌入式容器还是在部署war。还有什么不起作用呢？我希望

PostService

的名称应该是

PostService

，除非您在@Service或@Bean中定义自己的名称。为了正确创建胖jar，您缺少了spring引导插件。总而言之，很多信息缺失，而且与您的示例中的情况不符。+1。重写由spring boot starter父级管理的allready版本的依赖项会给您带来很多麻烦。
