Spring MVC 3, Interceptor on all excluding some defined paths
Solution 1:
Since Spring 3.2 they added that feature with the tag
mvc:exclude-mapping
See this example from the Spring documentation:
<mvc:interceptors>
<bean class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor" />
<mvc:interceptor>
<mvc:mapping path="/**"/>
<mvc:exclude-mapping path="/admin/**"/>
<bean class="org.springframework.web.servlet.theme.ThemeChangeInterceptor" />
</mvc:interceptor>
<mvc:interceptor>
<mvc:mapping path="/secure/*"/>
<bean class="org.example.SecurityInterceptor" />
</mvc:interceptor>
Here's the link to the doc
Solution 2:
For java based configuration, from the docs
@Configuration
@EnableWebMvc
public class WebConfig extends WebMvcConfigurerAdapter {
@Override
public void addInterceptors(InterceptorRegistry registry) {
registry.addInterceptor(new LocaleInterceptor());
registry.addInterceptor(new ThemeInterceptor()).addPathPatterns("/**").excludePathPatterns("/admin/**");
registry.addInterceptor(new SecurityInterceptor()).addPathPatterns("/secure/*");
}
}
Solution 3:
When configuring an interceptor, you can specify a path pattern. The interceptor will be invoked only for controllers which the path matches the interceptor path pattern.
ref: http://static.springsource.org/spring/docs/3.1.x/spring-framework-reference/html/mvc.html#mvc-config-interceptor
But as you probably noticed it, the path pattern doesn't support exclusion.
So I think the only way is to code a blacklist of paths inside the interceptor. When the interceptor is invoked, retrieve the HttpServletRequest.getRequestURI()
and check if the path is blacklisted or not.
You can build the blacklist inside a @PostConstruct
annotated method of the interceptor, and so get the blacklisted path from a property file for instance.
