spring mvc完全基于注解的参考示例

web配置

public class SpitterWebInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {

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

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

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

}

视图解析器等

@Configuration
@EnableWebMvc
@ComponentScan("spittr.web")
public class WebConfig extends WebMvcConfigurerAdapter {

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

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

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        // TODO Auto-generated method stub
        super.addResourceHandlers(registry);
    }

}

控制器

@Controller
@RequestMapping("/")
public class HomeController {

    @RequestMapping(method = GET)
    public String home(Model model) {
        return "home";
    }

}

其它配置类

@Configuration
@Import(DataConfig.class)
@ComponentScan(basePackages = { "spittr" }, excludeFilters = {
        @Filter(type = FilterType.CUSTOM, value = WebPackage.class) })
public class RootConfig {
    public static class WebPackage extends RegexPatternTypeFilter {
        public WebPackage() {
            super(Pattern.compile("spittr\\.web"));
        }
    }
}

@Configuration
public class DataConfig {

    @Bean
    public DataSource dataSource() {
        return new EmbeddedDatabaseBuilder().setType(EmbeddedDatabaseType.H2).addScript("schema.sql").build();
    }

  @Bean
  public JdbcOperations jdbcTemplate(DataSource dataSource) {
    return new JdbcTemplate(dataSource);
  }
