@Configuration
@EnableWebMvc // 会帮我们开启一些web mvc的默认配置：比如viewResolver或者messageConverter
public class MyConfiguration{
    @Bean
    public InternalResourceViewResolver viewResolver() {
        InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
        viewResolver.setPrefix("/WEB-INF/classes/views/");//这是编译后jsp的路径
