setUnauthorizedUrl不起作用

setUnauthorizedUrl("/403")不起作用

 

 

SpringBoot中集成Shiro的時候, 配置setUnauthorizedUrl("/403")了,但是不起作用,只會在控制檯打印UnauthorizedException異常信息:

原因:
Shiro源碼中是這樣做的:

 

    private void applyUnauthorizedUrlIfNecessary(Filter filter) {
        String unauthorizedUrl = this.getUnauthorizedUrl();
        if(StringUtils.hasText(unauthorizedUrl) && filter instanceof AuthorizationFilter) {
            AuthorizationFilter authzFilter = (AuthorizationFilter)filter;
            String existingUnauthorizedUrl = authzFilter.getUnauthorizedUrl();
            if(existingUnauthorizedUrl == null) {
                authzFilter.setUnauthorizedUrl(unauthorizedUrl);
            }
        }

    }

只有perms,roles,ssl,rest,port纔是屬於AuthorizationFilter,而anon,authcBasic,authc,user是AuthenticationFilter,所以unauthorizedUrl設置後不起作用,只會在控制檯打印異常信息。

接下來,我們需要做一些配置,自己來處理UnauthorizedException異常:

1.第一種方式

 

@Configuration
public class ExceptionConf {

    @Bean
    public SimpleMappingExceptionResolver resolver() {
        SimpleMappingExceptionResolver resolver = new SimpleMappingExceptionResolver();
        Properties properties = new Properties();
        properties.setProperty("org.apache.shiro.authz.UnauthorizedException", "/403");
        resolver.setExceptionMappings(properties);
        return resolver;
    }
}

當然,還有其他的方法可以自己處理。
比如:

2.用spring mvc的統一異常處理類HandlerExceptionResolver

定義一個類繼承HandlerExceptionResolver,然後判斷UnauthorizedException異常即可。

 

public class MyExceptionResolver implements HandlerExceptionResolver {

    @Override
    public ModelAndView resolveException(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o, Exception e) {
        if (e instanceof UnauthorizedException) {
            ModelAndView mv = new ModelAndView("/403");
            return mv;
        }
        return null;
    }
}

然後,在啓動類中註冊該bean

 

@SpringBootApplication
public class DemoApplication {

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

    // 註冊統一異常處理bean
    @Bean
    public MyExceptionResolver myExceptionResolver() {
        return new MyExceptionResolver();
    }
}
