這裏是我的Application.java樣本要點春季啓動viewControllerHandlerMapping配置
@Configuration
@EnableAutoConfiguration
@ComponentScan(basePackages = "org.com.app.client.controller")
@EnableJpaRepositories(basePackages = "org.com.app")
@EntityScan(basePackages = "org.com.app.model")
public class Application extends SpringBootServletInitializer {
public static void main(String[] args) {
ApplicationContext ctx = SpringApplication.run(Application.class, args);
}
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(Application.class);
}
/**
* Spring Web MVC Confugrations
*
**/
@Bean
public ExceptionHandlerExceptionResolver exceptionHandlerExceptionResolver(){
ExceptionHandlerExceptionResolver exceptionHandlerExceptionResolver = new ExceptionHandlerExceptionResolver();
return exceptionHandlerExceptionResolver;
}
@Bean
public ViewResolver internalResourceViewResolver(){
InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
viewResolver.setPrefix("/WEB-INF/jsp/");
viewResolver.setSuffix(".jsp");
return viewResolver;
}
然而，當我嘗試運行我的MVN春季啓動：運行該例外總是發生。我錯過了什麼？

我認爲這個問題可能是你正在使用的嵌入式tomcat的版本，你似乎已經拉到了8.0.3版本，而Spring Boot 1.2.3的版本應該是8.0.20，可以你檢查你爲什麼得到這個舊版本，並應該解決你的問題 – 2015-04-04 05:58:34
