spring 拦截器整体配置

1.spring boot拦截器默认有

• HandlerInterceptorAdapter
• AbstractHandlerMapping
• UserRoleAuthorizationInterceptor
• LocaleChangeInterceptor
• ThemeChangeInterceptor

2.配置spring mvc的拦截器WebMvcConfigurerAdapter

1. public class WebAppConfig extends WebMvcConfigurerAdapter

3.实现添加拦截器方法

1. public void addInterceptors(InterceptorRegistry registry){
2. }
3. 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

1. public class WebAppConfig extends WebMvcConfigurerAdapter{
2. public static void main(String[] args) {
3. SpringApplication.run(WebAppConfig.class, args);
4. }
5. /**
6. * 配置拦截器
7. * @author lance
8. * @param registry
9. */
10. public void addInterceptors(InterceptorRegistry registry) {
11. registry.addInterceptor(new UserSecurityInterceptor()).addPathPatterns("/user/**");
12. }
13. }
14. UserSecurityInterceptor代码
15. public class UserSecurityInterceptor implements HandlerInterceptor {
16. @Override
17. public boolean preHandle(HttpServletRequest request,
18. HttpServletResponse response, Object handler) throws Exception {
19. return true;
20. }
21. @Override
22. public void postHandle(HttpServletRequest request,
23. HttpServletResponse response, Object handler,
24. ModelAndView modelAndView) throws Exception {
25. }
26. @Override
27. public void afterCompletion(HttpServletRequest request,
28. HttpServletResponse response, Object handler, Exception ex)
29. throws Exception {
30. }
31. }
