spring-boot 加入拦截器Interceptor
1.spring boot拦截器默认有
- HandlerInterceptorAdapter
- AbstractHandlerMapping
- UserRoleAuthorizationInterceptor
- LocaleChangeInterceptor
- ThemeChangeInterceptor
2.配置spring mvc的拦截器WebMvcConfigurerAdapter
- public class WebAppConfig extends WebMvcConfigurerAdapter
3.实现添加拦截器方法
- public void addInterceptors(InterceptorRegistry registry){
- }
- registry.addInterceptor可以通过此方法添加拦截器, 可以是spring提供的或者自己添加的
4.实例部分
- public class WebAppConfig extends WebMvcConfigurerAdapter{
- public static void main(String[] args) {
- SpringApplication.run(WebAppConfig.class, args);
- }
- /**
- * 配置拦截器
- * @author lance
- * @param registry
- */
- public void addInterceptors(InterceptorRegistry registry) {
- registry.addInterceptor(new UserSecurityInterceptor()).addPathPatterns("/user/**");
- }
- }
- UserSecurityInterceptor代码
- public class UserSecurityInterceptor implements HandlerInterceptor {
- @Override
- public boolean preHandle(HttpServletRequest request,
- HttpServletResponse response, Object handler) throws Exception {
- return true;
- }
- @Override
- public void postHandle(HttpServletRequest request,
- HttpServletResponse response, Object handler,
- ModelAndView modelAndView) throws Exception {
- }
- @Override
- public void afterCompletion(HttpServletRequest request,
- HttpServletResponse response, Object handler, Exception ex)
- throws Exception {
- }
- }

想问下,我配置的这个拦截器为啥没有生效呢?
