Interceptors Configuration using Java or XML

In this section, you will learn about how to configure interceptors using Java or XML.

In Spring MVC, you can configure HandlerInterceptors or WebRequestInterceptors , which can be applied to all incoming requests or confined to particular URL patterns.

Given below sample code for registering interceptors in Java :

@Configuration
@EnableWebMvc
public class MyAppWebConfig 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/*");
	}

}

You can do the same in XML using the <mvc:interceptor> as follows :

<mvc:interceptors>
	<bean class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor" />
	<mvc:interceptor>
		<mapping path="/**"/>
		<exclude-mapping path="/admin/**"/>
		<bean class="org.springframework.web.servlet.theme.ThemeChangeInterceptor" />
	</mvc:interceptor>
	<mvc:interceptor>
		<mapping path="/secure/*"/>
		<bean class="org.example.SecurityInterceptor" />
	</mvc:interceptor>
</mvc:interceptors>
