spring boot 作为微服务的便捷框架,在错误页面处理上也有一些新的处理,不同于之前的spring mvc 500的页面处理是比较简单的,用java config或者xml的形式,定义如下的bean即可

< bean
class = "org.springframework.web.servlet.handler.SimpleMappingExceptionResolver" >
< property name = "exceptionMappings" >
< props >
< prop key = "org.apache.shiro.authz.UnauthenticatedException" >pages/403</ prop >
< prop key = "org.apache.shiro.authz.UnauthorizedException" >pages/403</ prop >
< prop key = "org.apache.shiro.authc.LockedAccountException" >pages/locked</ prop >
< prop key = "java.lang.Throwable" >pages/500</ prop >
</ props >
</ property >
</ bean >

404就比较特殊了,有2种方法可以参考:
1. 先设置dispatcherServlet

@Bean
public ServletRegistrationBean dispatcherRegistration(DispatcherServlet dispatcherServlet) {
ServletRegistrationBean registration = new ServletRegistrationBean(
dispatcherServlet);
dispatcherServlet.setThrowExceptionIfNoHandlerFound( true );
return registration;
}

再增加处理错误页面的handler,加上@ControllerAdvice 注解

@ControllerAdvice
public class GlobalControllerExceptionHandler {
public static final String DEFAULT_ERROR_VIEW = "pages/404" ;
@ExceptionHandler (value = NoHandlerFoundException. class )
public ModelAndView defaultErrorHandler(HttpServletRequest req, Exception e) throws Exception {
ModelAndView mav = new ModelAndView();
mav.addObject( "exception" , e);
mav.addObject( "url" , req.getRequestURL());
mav.setViewName(DEFAULT_ERROR_VIEW);
return mav;
}
}

不过上面这种处理方法,会造成对js,css等资源的过滤,最好使用第二种方法
2. 集成ErrorController

@Controller
public class MainsiteErrorController implements ErrorController {
private static final String ERROR_PATH = "/error" ;
@RequestMapping (value=ERROR_PATH)
public String handleError(){
return "pages/404" ;
}
@Override
public String getErrorPath() {
// TODO Auto-generated method stub
return ERROR_PATH;
}
}
