spring boot加入拦截器Interceptor过程解析
这篇文章主要介绍了spring boot加入拦截器Interceptor过程解析,文中通过示例代码介绍的非常详细,对大家的学习或者工作具有一定的参考学习价值,需要的朋友可以参考下
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 { } }
